How To Make DIY Organic Pest Spray For Your Fruit Trees!

- In this video I will explain how to formulate and apply your own dormant oil spray for fruit trees.
The goal, with properly applied dormant oil spray, is that the fruit tree is rendered free of harmful bugs as well as their eggs and fungal spores.
This recipe has been proven for me on the following fruit trees: crabapple, apple, plum, pear, quince & currants.
There are optimal time windows to apply the spray, I’ll explain what needs to happen BEFORE and AFTER the application so that you can be sure your timing is right on!
For each gallon (~4 liters) of water you add these 3 ingredients:
1 cup veg oil
1 tablespoon baking soda
1 tablespoon pure castile soap
Thanks so much, Stacey, this was exactly what I needed. I've been intimidated by the whole idea of spraying my apple trees, but this diy organic solution makes it so accessible. Got the job done this morning!
I do the sticky wrap around the trunks in the autumn, which has decreased the leaf and blossom destruction, but looking forward to seeing the benefits of this spray as well.
Well done Shelly - I'm glad this was helpful for you!
May your trees be fruitful :)
my apple trees are being eaten by something the leaves are going brown and dying what can I spray on the leaves to stop the insect or fungus that has formed? have you used neem oil and what was your experience compared to veggie oil?
Do you have uptates with this ? 😃
This is EXACTLY what i was looking for.
Straight to the point, essential details & demonstration.
Thanks.
right on - i'm glad it was helpful!
I boiled garlic and mixed that with dishsoap. No more critters eating my peaches. It's the first year so far and it's working great
Thanks for the input infinite!
What time in the season do you spray your mixture on the peach tree?
When you used dish soap, are you referring to “dawn” or Meyers natural? Please update-can you spray after there are fruit buds?
I appreciate very much the great recommendation to be save n get read of bags n fungus from our fruit trees ,I'm glad you are sharing, hope a lot of people will be very helpful ,thanks
I do that for my trees and my body because insect and worms and mites are coming out from my skin we got it from our tree when we tream them before and tiny mites and worms are coming out thank you so much 🙏
Interesting. Sounds like you are using vegetable oil the same way that many would use Neem oil. Thanks for sharing. 💜
Thank for this information, I have 23 trees to spray so this is perfect
Wow - you've got your own piece of orchard heaven. I'm glad it was helpful!
Thank You, this information was very helpful@@SustainableStace
Than you so much! I just planted new trees and the bugs are all over them already. They are between 4 and 6 feet tall.
I love that this is organic and a win-win situation!
I'm glad you like it! Me too
thanks Stacey, was just going to order a kit but will use your method instead. Kudos to your efforts to slowly
change us to appreciate nature more.
Fantastic Irene. I'm glad that was helpful!
Hi am new to fruit trees i have a apple tree and its never been treated because i moved into the house so i want to look after the tree really good apples 🍎
a healthy tree is most resistant to disease and pests!
you may not need a spray. What would be helpful is thoughtful pruning, some lime around the drip line and some other possible steps depending on the trees age, shape etc
another little video that may help: th-cam.com/video/tHLCE72MKb0/w-d-xo.html
Great Vid. Does this work on the leaves that have spots on them already? I just planted my first tree...so I'm new to this. Appreciate the help.
Thank you for sharing. Going to use on my fruit trees this year. Will give you feed back on how this went may be in year.
Sounds great!
@subbashpatel9615 update?? Did this work for you?
What can I use if my Apple tree already has baby apples? I got the tree 3 weeks ago and have a pest issue already. Please help 😮
It's a baby apple tree crisis. I'm sorry that you have pests right away.
What you do will depend on what pests you have.
With aphids, I would hose them off. With caterpillars I would cut off the besieged branches.
You'll need to know what pests you have to successfully deal with them.
Can I use any kind of oil like grape seed oil or olive oil?
yes. the oil stops the pest from breathing. any oil should accomplish that!
Perfect! And luckily I have all the ingredients already on hand. But I think I’ll stand UPWIND rather than “downwind” as you suggest [5:20] 😂 😘
ha!
Yeah, that sounds a bit more thoughtful.
Are we just spraying the trunk or do we go up the branches as well?
Every place there is bark you want to spray - so . . . branches and trunk!
Great info. Love that you tell us why we need to use things in your videos. My questions that I need addressed are: How often do you spay this? What about after the leaves appear, what do you use then? What do you do when the fruit appears? Hopefully you have videos on the way that will cover these topics. Thanks
I usually only spray once. The window that's suitable doesn't usually allow for more than twice in a season.
I don't spray any further in the season. Pests will vary place to place and people who wish to spray may need something quite specific. It could also be quite hazardous to the environment/fruit safety when sprays are applied and all of nature is alive and buzzing so I avoid it.
When the fruit appears, I thin it (removing excess numbers ) so that a few fruits per site will have ample space to grow full size.
wishing you well :)
Thank you stay blessed very well explained
You're welcome Firoza - and blessings to you as well.
Need advice: So i'm a newbie to caring for apple trees...I have 2 but never produced but this year, I finally educated myself and now see that I have apples, the little bumps underneith the dead blooms....I also noticed its full of those little worms so handpicked them out but I need to spray so my question is, can I spray this on now? Will it kill the worms and not harm the apples?
Thanks 😊
Hi Nathalie - great question.
Welcome to the channel.
The spray is not meant to address worms. It's meant for insects that breathe thru their bodies and spend winter in the bark/wood of the tree.
It's also key that this spray is only used BEFORE fruit has set on the tree.
good luck!
Thanks! I'm really new to having an apple tree. Need to do a lot of pruning this fall.
You're welcome Veronica.
Good luck with the new apple tree!
How many times needs to spray it on trees. Early spring, summer
My goal is to apply it thoroughly, ONCE!
@@SustainableStace just apply it thoroughly once for the whole year. Thanks
Thanks. Sounds like a great dormant spray recipe
You're welcome - good luck with it !
Great video. What can I spray on my trees after my fruit appears. My plum trees are loaded with small plums and I would hate to loose them to bugs. Help please
After fruit appears is something I'm not familiar with.
There's so much LIFE on the tree at that point, not to mention it's the actual fruit you're going to eat, that I'm not keen on spraying a tree once the fruit has set.
I have heard of some people simply using dish soap and water to control bugs on fruit trees.
The dormant oil sounds like a good addition to that for early in the season.
Yes, the soap is what does the hard word in dealing with bugs. The oil help the soap cling / adhere to the critters better which should increase success!
I tried dish soap for the first 4 years after I planted them. The bugs aren't deterred by dish soap. They seem to still hatch. After they hatch and you find them on the tree, I soaked the tree with dish soap. The bugs fall off quickly onto the ground and the next day they crawl right back up.
@@hamiltongoldbugwhat kind of soap did you use?
Excellent video… very thorough is this good for tree borers
Hello Tanja, I don't have tree borers on our fruit trees so I cannot say I know for sure.
@@SustainableStace Thank you for responding. Some utubers don't even reply. 👍🏼
Thanks, and can you use Olive Oil instead of veg. oil?
You bet, oil will do what needs to be done (olive or veg) . It prevents the pests from breathing.
Do you have any suggestions for bitter rot on apple trees. thank you very much.
Yes, it' a fungus that's resting in the wood. You need to identify and remove the wood that is harbouring the fungus.
Does this work on honeycrisp apple trees?
YES it's excellent for any variety of apple!
@@SustainableStace thank you! Waiting for it to warm up more here in Northern Mi before I can do this :)
Does this work for flies? I have some sort of small fly laying bunches of eggs on my apple trees and pear trees. The eggs hatch and the larva are sucking the juice out of my leaves. They are going from a dark green color to a light yellow color and falling off.
Thanks I need advice how to treat the white things that's causing the trees just to become dry it's a lemon tree?
Hello Ihemba - i'm curious to know what 'white things' your lemon tree is troubled by. I have very little experience with Citrus because I live in a climate too cold to grow them!
Hi, I am in New York and I have a peach, plum and cherry tree on pots, this is my first year for the cherry and plum, my peach already has some fruit. What can I use to keep them healthy and how often do I have to fumigate them. Thank you
Hello Alba - that's series of great questions. I'm unsure what your weather, sun exposure and most prevalent pests are in your area.
The peach I would focus on keeping under cover - so no rain hits it. The others should be pruned for good air circulation.
I only spray once in spring, and then I sometimes handpick off tent caterpillars on the apple trees as the fruit is setting - but often various birds come in and do the job for me!
We have a pear tree that we sprayed using your recipe early in the season. It was growing beautifully, but now there are branches or portions of branches that have turned black and withered. It is loaded with small pears. What can I use on it now to keep from losing this crop?
That's unfortunate.
You sprayed for pests that overwintered. But, your tree has likely been hit with a fungus that overwintered.
from a google search:
"Pears with black rot have been infected by a fungus called Physalospora obtusa (syn. Botryosphaeria obtusa). It overwinters in cankers on trees and in leaf matter, old fruit, and twigs on the ground. The prime conditions for infection are warm and wet weather in the spring."
You'll need to identify and remove the wood that is harbouring the fungus.
Hi! Thank you so much for this homemade spray. I just ordered Casteel soap to get started. How often do I use this spray?
Application of this spray is meant to be done in a fairly tight time window. When I shared the info, i was thinking only once.
However, I can see how doing it twice in a 10 day or two week window would make sense.
Hi,
Thanks for share with your patent. Will it works on Japanese beetles?
I don't know if I have Japanese beetles affecting my trees and so i cannot speak with experience.
does the oil mix with the watter? or will it be sprayed last when the content of the bottle is done
Great question - it mixes when the sprayer is pressurized and comes it well mixed!
Thanks for the video. I have 3 young trees. Plum, apricot and apple (no fruit). I noticed yesterday that the plum has what I believe is an aphid and the beginning of ants. The trees are new this year and I didn't see this video. It is now late summer. Is it too late in the year to spray this treatment? I just need some clarification. Thanks
Ants farm aphids. Anyplace you find aphids there are ants first!
Only use this spray when there are no flowers / fruit on your tree.
You can always use a water hose and spray your trees down, that can help a lot to eradicate little pests.
Thank you. I love that it's organic. Most channels also recommend copper. What's your take on that please?
Hi Linda - thanks for asking.
The spray in this video is dealing with pests that have overwintered.
Copper is meant (primarily) to address fungus (or bacteria) harmful to the tree. It's considered suitable in moderation and can be used in organic settings.
I found this article helpful to read: www.epicgardening.com/copper-fungicide/
wishing you well!
@@SustainableStace Thank you for that link. The article was helpful
Thank you for this great tip. Could I use soft soap instead of the Castile soap as well?
You're welcome and yes you can!
Hi there, I see from one of your comment to only spray on the bark. If it is also used to treat rust though should it not also be used on the leaves? Thanks :)
Hi Pink Frost - when i'm applying my spray i'm trying to cover all the bark and that's usually what's providing habitat for pests.
It won't hurt to spray the leaves as well if leaves are on the trees when you're spraying.
What do you recommend for aphids or mites after the fruit starts?
Hi Cyndi - great question.
We have problems with aphids at times and I've done a video to address that:
th-cam.com/video/6T_cUeD6mRc/w-d-xo.html
I use 50 /50 mix of castile soap and oil. Dr bronners has mint which is a natural deternet to bugs also
Fantastic - amazing how the mint helps out and smells good. I love the Dr. Bronners for this purpose!
where do get castile soap or can dawn soap be used?
Yes, Dawn soap can be used.
Last year I got first time lots of peaches but all of them has worm inside, even before riped( still green( what I can do to prevent from worms this year???
That's a discouraging experience - it sounds like your harvest was ruined and you didn't get to enjoy it.
step by step:
1) You should find out if the worms are overwintering and residing on the tree OR if they come to the tree after it starts to flower and fruit.
2) Once you have that figured out you should discover the best treatment for the type of worm that's attacking your peaches.
good luck :)
Would a vegetable based natural and gentle dish soap work?
Yes, absolutely!
Your video and spray is great . I was using cinnamon bark oil, vegetable oil and water this year. So my question to you is this it for spraying the tree for the season? Or do you spray with something there after the leaves are out up to and before the buds open . And after the flowers bloom. Please reply
Thanks for the comment and the question.
Yes, this is it for the season. After I've done this spray, the likely next challenge is tent caterpillars which I remove by hand as they cluster.
Does this work on trees that are already bearing fruit? The plum tree is heavily producing but each one has little white worms in them 😢
Good question.
This is a DORMANT scpray so dealing with worms on fruit will need a different strategy.
I think this info might be what you need for your plums to have a winning season!
www.gardenworld.co.uk/case-study/how-to-control-apple-and-plum-maggots/
If I have leaves uncurling and opening up, but no open flowers yet, can I spray this?
Yes, that should work fine. You just want to ensure the spray is on the tree before pollinators are hitting the new flowers.
I have a tree with aphid infestation. The aphids cause a white sticky mess that not only attracts bees but drips all over my patio. It started last year and besides from spraying the tree down with a hose nothing works because they keep coming back. Will this formula work for aphid infestation and if so is it too late to apply?
This is a great question. I don't suggest Dormant Oil Spray for Aphids.
I've got a video specifically for dealing with Aphids: th-cam.com/video/6T_cUeD6mRc/w-d-xo.html
What if you already have leaves and fruit? Will this still work? I tried using neem oil on my soursop tree, but it burned my leaves, and they fell off. And yes, I did apply this during the evening.
Good question - It's meant to be applied when the tree is just emerging from dormancy.
So . . no, hot when there are leaves and definitely NOT when there's fruit.
Hi there
Is dish soap a good substitute for the casteel soap . Thank you in advance.
It's a great question. The answer is 'it depends' on the type of soap you use. In my view - getting quality soap with fewest harmful ingredients is worth the search.
@@SustainableStace
Thank you for answering
I appreciate it.
Can I still do this after the apple tree has flowered and fruiting like now (in Michigan)?
It's a spray intended to be used / applied when the tree is DORMANT, it's a dormant oil spray. So, I would not advise applying this when the tree is out of dormancy.
Thanks for the info! How often do you spray? Just once a year? Or throughout the season?
Just once a year.
Can u spray when they already flowering. Or is it too late? What can u do in this case
Good question. It's meant to be DORMANT spray so . . . .it's too late to use a dormant oil spray when the tree is flowering.
Thanks for the good advise.
You're welcome Nazgul!
Thanks.
How often should I do that?
great question - one thorough treatment in spring should be sufficient.
Thank you for your video. Its very informative. I just have a question. Can you use this for tomatoes and eggplants? How many times do I have to spray the plants using this formula specially for the vegetables.
I'm glad you liked the video and thanks for the question.
This is meant for overwintering pests on fruit trees.
I'm curious - what pests are you encountering on tomatoes and eggplants which you are wanting to address?
@@SustainableStace The pest on the tomatoes are fruit flies and shoot borer for the eggplant. almost all of the tomatoes are damaged by the fruitflies. Dont know if we can save some of the tomatoes as well as the eggplants. I'm located in the Philippines and weather is extremely hot. I've been trying to look for ways for organic ways to shoo these pests
Can we also spray this on rose bushes and when can we add neem oil. Can I use this on my lemon and guava trees. Thanks
It would work on rose bushes for sure. As for the other trees - I don't grow lemon or guava trees so I cannot advise.
Can I use olive oil or coconut oil instead of canola oil? thanks
Hi Dave,
I'm quite sure that coconut oil will be tough b/c it becomes a solid at room temperature.
Likely olive oil would work!
Thanks for your video
How often should this be done? I am new to learning about fruit trees and I have cherry trees and something ate all the leaves on them. When is best time to do this? And can this be done on vegetables also?
Great questions!
This is meant for a single use. In the spring when the tree is still dormant - before flowers/blossoms start.
For veggies, which are mostly annuals (unlike fruit trees which are perennials) there are no overwintering pests.
So, you'll usually be contending with aphids or mites which feed on your plants as they mature and get tasty!
here's a link to my video on dealing with Aphids . . .
th-cam.com/video/6T_cUeD6mRc/w-d-xo.html
happy growing !
Will this help with cedar rust? When should I spray?
I am not familiar with cedar rust. it's meant to kill pests / insects / bugs b/c the oil and soap kill them. If cedar rust is not a pest / insect / bug then I expect it will not be useful
Re: the time to spray - as explained in the video - needs to be before the buds/flowers open b/c this ensures the pollinators are not harmed by the spray
It’s summer now and blackberries are already falling, is there something i can spray with now? I just moved in and would love to eat the fruit instead of washing it away
Hmm - you must be somewhere MUCH warmer than where I live!
If fruit is already ripe, it's not an advisable time to be spraying.
My trees are fairly tall, am I supposed to spray all of the branches as well? and since my trees are overgrown and need some TLC how much of the branches can I trim off in the fall to get my trees healthy again?
Hello Angela - yes, the goal is to apply spray on ALL surfaces/bark where pests could have overwintered.
Pruning is key to shape the tree to capture light, increase airflow and increase chances for flowers and fruit.
Different trees can manage different amounts of pruning. For instance, my apple trees can sustain up to 20-30 of the total tree being pruned in fall/winter and still produce well. Though I don't do that much pruning usually.
However, prunes/plums don't sustain that volume of pruning without giving up a year of production.
I've got a video to help: th-cam.com/video/lTvBGAXaQ28/w-d-xo.html
Thanks for this natural recipe. It’s post flower time for my Italian plum tree and that scale is all over my tree. Is it too late to use this spray? Do I have to use something else now? Thanks
You're welcome.
The spray will likely working on 'that scale' !
As long as no pollinators are at risk - and they shouldn't be now the flowers are done - it's a very low risk trial.
Can you please let me know how it goes? I'd love to know !
Thanks for this, in UK could you replace Castile soap with eco dish soap which is much cheaper please! Thanks
Yes you can!
Will this work for Concord grapes?
Good question Kevin.
I'm unsure if this would work for grapes. Generally I think grapes have more issues with mildew, rot, fungus etc and this spray is more about pests.
I grow a variety of different grapes. They're so healthy and have no pests. I've never considered spraying them. I wish I could offer more guidance.
Wishing you well.
Please let me know if I can use dish detergent instead of Castile soap?
Hi Maria - yes you can.
Different dish detergents will have different levels of safeness for the environment.
@@SustainableStace Thank you for replying me quickly, my plum branches has bug's nest on them from last year.
what can be used when fruit is on the tree? The Jap beetles are bad in our area
Hi and good question.
Sorry, I don't know what to do in that situation. All the reading I do suggests a chemical spray for those beetles.
My tree is grafted peach and plum. think this will work on peaches as well?
Yes, I do!
Hello sir how to control pod borer in my vegetable please have a Idia
Hello Faizal, it's a very good question.
I do not have pod borer problems and so I don't have experience or proven solutions that I can offer.
I hope you are able to find a great solution. When you do, can you please share with me?
Ok sir
Thanks very good
Most welcome
This is great, a couple of questions. Can you do this to cherry trees? And 2 do you just spray the trunk or the whole tree? I have 2 big 15’ cherry trees and have been struggling with store bought stuff. Can’t seem to help. Thank you
Hello Jaime,
Yes you can do this for cherry trees. You want spray ALL areas where insects/eggs could be hiding on the bark of the tree.
So, you want to spray the trunk, all the branches - everything. I hope it's highly successful.
I know sometimes there are insects that can cause little holes in the leaves -looks like a shotgun blasted the tree. I believe that to address that you'll need a spray that has some copper in it.
I have some lavender scented pure Castile soap on hand. Would that be okay to use?
Yes it will!
@@SustainableStace thanks!!
Can this be sprayed on the trees during the fruit stage?
nope - it's meant to address the pests that OVERWINTER in the bark / wood of the tree.
So, once the tree is in leaf and the flowers (and beyond stages) are in play - you're going to be dealing mostly with flying insects which need a different response.
if I want to use a hose sprayer instead of a pump sprayer, I'm assuming I put the same amount of ingredients per gallon mark into the sprayer, right?
Hi Tom - yes that's correct.
how many ounces of oil is in the cup you using, it look like more than regular 8 ounce cup
Hi Edward -
Yes, a that is an 8 oz measure for the oil !
The recipe is in the description of the video.
For each gallon (~4 liters) of water you add these 3 ingredients:
1 cup veg oil
1 tablespoon baking soda
1 tablespoon pure castile soap
can I spray this on trees with either blossoms formed but not open and trees where the buds of growth are an inch or 2 long. Thanks
The spray will not hurt the tree in any way no matter when it's applied.
The concern / caution is always re: the impact on pollinators.
If there are blossoms (even formed and not open), there are likely (hopefully!) pollinators trying to get at the blossoms and so the spray shouldn't be applied then.
Probably too late to get a reply but you only showed spraying the trunk. Do you spray all the branches, too?
I spray all surfaces of the tree which have bark. Anyplace where overwintering pests may be hiding - the most likely places are the oldest, most creased/wrinkly bark on the main trunk.
Great Video, I am on it. Thank You
Hi Willie - I'm glad it helped!
thank you I would like to try this
Go for it Becky!
@@SustainableStace I made it today!! Trying it out thanks!
What can I use mid summer? I have leaf folders and they had been able to establish bc of ants. Dealt with the ants yesterday but wonder if I could use a DIY soap spray now, but it is July. Thoughts? Recipes, suggestions?
Hmm you got me thinking.
I don't know of any organic methods for dealing with leaf folders.
Depending on how wide spread it is, I wonder if you'll be able to spray them off with a garden hose?
Should I spray the ground?? About the area of drip line of the tree?
Thank you.
It's a good question. No, I don't think so.
Typically in spring, around the permiter of my fruit trees, I scatter lime after having pruned them. That helps balance soil pH and my chickens move in and look for any little critters & bits - that typically cleans things up nicely :)
Hi, not sure if you can help me. I have two medium/large birch trees that have produced this horrible sap like stuff thats covered my shed and garden table. On closure inspection every leaf is covered in aphids. I do have a sprayer.. what safe solution could i apply please to get rid of them (and sap) because there are a lot of birds that come down on feeders which i hang in the trees and just wary of the cats children close by too. Need something safe. Thankyou.
Hello !
How about considering some of the recommended solutions in this video focused on eliminating Aphids?
th-cam.com/video/6T_cUeD6mRc/w-d-xo.html
Love the video. I live in southeast Alaska and my trees have a lot of moss, lichen. Can I add something else to that so I can take care of that as well? Thanks again for your well done video
That's a great question! I also have moss on the trunks of my older fruit trees.
My initial answer is "i'm not sure" not super inspiring right?!
The concern I have is that something which kills one plant (moss or lichen) will very likely have negative effect on the fruit tree as well.
Detergent (laundry) diluted in water and sprayed on would very likely kill the moss but I'm not sure of the effect on the environment nor the tree hosting the moss.
If you come across a miracle solution - can you please message me back and let me know what you find?
I assume you do the branches too? I have heard of adding garlic, hot pepper and cinnamon oil. Thank you!
Yes I do!
Gotta spray every bit of habitat which a pest could be living on / in .
Ok my trees have blossoms and buds on them. Can I still use this spray?
Hi Charlene - it's a good question and the most common one :)
The spray / concepts is meant for DORMANT trees i.e. during the time of the year when they are not active or growing.
The spray will harm any insect that it touches including pollinators like bees.
So . . . NOPE you should not use this spray once blossoms have opened up too attract pollinators.
Hello. It’s the latter part of April here in Michigan. I live a fair distance from my trees, so I’m not sure about blossoms yet. If they have budded, is it okay to just spray the trunk?
Hi Ed - yes, that'll be fine.
Can I use this spray in hot July. I have black beetles on my apple tree?
The spray is intended for overwintering pests and I don't think black beetle would fit that category.
The spray is meant for early spring application.
So what do you spray if things are already flowering and blooming? Its May 7 and things are blooming I have leaves full of bugs.
Let's start off by NOT assuming that spraying is the always the answer . . . .
If things are flowering and blooming and you start to spray - it'll be like dropping a bomb and hoping to only 'hit' the bad guys in the crowd - which is NOT going to happen.
You'll end up harming beneficial insects - esp. the pollinators.
So . .. you may need to choose a variety of options:
My most successful early spring activity is:
Mow the grass around the tree, treat with lime, put down a layer of cardboard and mulch - this can radically mute the pest population around & under the tree.
OR
1. live with the bugs
2. wait for birds to prey on them
3. purchase beneficial insects like ladybugs
4. hand pick off the bugs you don't like
5. if they are climbing the trunk - sticky wrap the trunk of the tree
6. mow the grass around the tree, treat with lime, put down a layer of cardboard and mulch - this can radically mute the pest population around & under the tree
How would you tackle spraying a huge apple tree? I'm talking 15ish foot tall and branch width of 25+ feet. A 2 gallon sprayer is not even going to touch 1/4 of the tree. Thanks.
Hi Ashlie - yes it's a good question.
Big trees are hard to tackle.
Many of our trees (a dozen or so) are about 10' tall and 20' across. The # of branches on the trees is key as well. Pruning well in advance, decreases a LOT of the surface area to spray.
A 2 gallon sprayer will do several trees the size of what you described if you have the mist set to 'fine' and you seize the opportunity on a day with no breeze.
Good luck - it can be a challenge.
Can you substitute with dawn soap?
yes, you can
@@SustainableStace appriciate the reply
Ok my trees don't really produce much fruit. What can I spray on them to help this process?
Hi Charlene,
you can do two things that will help your tree get healthier and produce more fruit which are always safe for insects:
1. prune them thoughtfully : th-cam.com/video/lTvBGAXaQ28/w-d-xo.html
2. cover the ground around the base (drip line) of the tree. I put down cardboard and bark mulch. Covering the soil always has a dramatic effect on the tree's health improving and decreasing pests!
What about sweet cherry trees? Would it work for these trees?
Yes it should !
Thank you for the video! What about a mixture for when the fruit starts developing and is vulnerable to fruit beetle stingrays in the baby fruit? Any ideas?
Hi Brian - great question.
I've not heard of fruit beetle stingrays.
Question: what kind of trees do you get those on ?
AND
where do you garden / grow fruit ?
I'll try to learn more about this!
@@SustainableStace Thanks for your reply. It was a mistake. Not stingrays! What I know about commercial pesticides is that they are applied just after flowering when fruits develop because some moths or beetles insert their into the fruitcake it's young and so the fruits if not sprayed early will grow with these eggs and rot partiality or fully. So my question: is your mixture and method the same I'm terms of timing (season) and type of pests its repelling?
We have an old pear tree in Portugal that my grandfather used to take care of when he was around. Today it still grows nice big pears however when we go to cut them open they are either rotten on the inside or have bugs. Would this spray resolve that or do we need something else?
Thanks
That sounds frustrating. Looks good but cannot be enjoyed - downer.
To know if this spray would work, we'd need to know if the bugs causing the damage are overwintering on the tree (then it would work!) OR showing up and infesting the fruit after it forms on the tree (then it wouldn't work)
@@SustainableStace Sorry for the late reply we did not go back this past year but will hopefully go in 2024. Since we are not there most of the year I'm not sure. But the bugs are for sure during when it has fruit. I dont think they are causing damage the rest of the year but only when there is fruit. They have been trying to apply disinfecting products the rest of the year but not sure if its been successful. Any suggestions?
An you use dawn dish detergent in place?
Hi Shelby - any type of sudsy detergent (including Dawn) will effectively kill the dormant pests.
But, it may be less safe on the plant. You're trying to keep the plant healthy MORE than trying to kill the pests :)
After the blossoms fall, should you spray again???
no. the goal is to spray well, ONE TIME, before the blossoms.
Could you do Olive oil as a vegetable oil substitute?
Yes !
How often should fruit trees be sprayed?
it's a great question Kimberly!
The answer is entirely based on your own tree(s) situation.
But realistically, the window of time to spray when the tree is dormant only permits (usually) 1 or 2 times each spring.
What if my trees have small fruit forming ? Is it too late?
good question - it's meant to be a DORMANT oil spray to kill what's been living in the bark and wood when the tree was DORMANT
so . . . . it's not the right application for the season when fruit is formed
Hello, how many time should we use this in a month ?
Thanks
I will try for my cherry apple plum and pear tree 😃
Hi Rahila, it's meant to be used one time, at the most twice, in spring.
The timing is very important b/c it needs to be AFTER the frost and BEFORE the flowers start to attract pollinators.
@@SustainableStace Oooh ok Thank you. My trees are "sick" actually and fruits are done. (I live in France). So I was wondering if I could do now.
