Every time I do a research into my garden issues, I end up finding the answer and the solution to the problem on this channel. Jason, thank you so much for sharing your expertise for free ))
The 4th of July I was at my best friend's house where she is just learning to become a gardener. She told me to come look at her rose bushes which were "filled with ladybugs." My first thought was, oh no she must have aphids but when I looked they were covered with Japanese beetles! As I'm trying to Google what would be safe to use on them she grabbed her spray bottle of water and peppermint essential oil and sprayed the plants. Not only did they disappear but several hours later they were still gone. Just a thought.
Thanks Rose
Great!
great
Capful of Dr bronners peppermint in the evening.
Thank you. I like this solution much better.
Hello Jason; for sure so many of us are grateful for your extensive information. I keep all your videos not only because they are of great help should I have problems, but because they are all so interesting and I enjoyed them. As you know I just have a small garden which is more than plenty for me, and I adore my roses 🌹. Thank you 🌹🌺🌸
Thank you Jason. I will be ready this rose season. Very appreciated to get clear information.
I just found these on one of my plants outside and lo and behold your channel pops up in my recommendations. Thank you so much!
Best of luck with them Allie!
What an amazing job you’ve done in explaining and describing this pest and things we need to know to fight the fight for our garden! Thank you, so much…👍❣️
This is great! This is more detailed in solutions than I've seen in rose books. I have a container garden of roses, geraniums, hydrangeas and more, so when they find me, they party.
Oh boy - I hope your damage hasn't been too severe!
Not as bad as the rose sawfly maggots, surprisingly. Probably because of the short time frame and being slowed up by my plants being mostly up off the ground. But your video also brought up grass damage, and we have very spotty grass around here, which is something I hadn't thought of before.
Thanks!!! new viewer. Very much to the point of subjects!!! Many other garden youtubers talk too much unessential to the subjects. I click off less than a minute viewing them.
Thanks for the all educational points you put out. and I love your garden background too. looks so pristine!!
Thanks - if I can keep people looking up at the mountains, they won't notice the weeds!
Thank you for sharing so much of your knowledge with us. You explain everything so well and I appreciate you very much.💚👍🐝
Thanks for the encouragement Peggy
Thank u sooo much for this. Last year we had a bad invasion and have been looking everywhere on the internet how to deal with the problem. Finally, after your video, Feel armed and ready to get 'em!!!!!
I saw damaged roses a few days ago. It is a good review. Thank you!
I’m so glad to have found this video. I have been battling Japanese beetles for two years on my roses. I now know what to do. 🙏🏽
Thank you for the finite explanation of who the Japanese Beetle is and how they make their way onto our plants, and now armed with new information, we can redirect them. =)
Thanks. As always your information is clear and scientifically based. I used to have only once blooming heirloom roses that finish before JB season, but decided that they weren’t going to win and have added others during the past few years. They also LOVE cuphea and a few others. You have provided new tools in my armament. Kathleen, 5b
Thanks Kathleen
As always, incredibly succinct and helpful! Thank you!
My pleasure. Thanks for watching
Thanks so much! Your videos are always so informative.
You are awesome!!! Without doubt, this is THE most comprehensive JB control guide. Very practical and timely, thanks a lot Jason😃
My pleasure Amy - thanks for watching
agreed
Thank you so much. I think this explains both the brown patches in my lawn and the holes in my grape leaves! Thank you!
Thank you this was so informative because I see now the damage going on with my plants. My hibiscus plant is like a skeleton when I checked yesterday. I will be on it, now I know what's attacking my plants. Thank you again, first time finding this channel.
Once again, Jason you come though with the info we need. I get these but not in huge numbers. I would like to keep it that way so I'm going to follow your advice.
Thanks Dennis
I was out with my dogs around 2 am and saw the Japanese Beetles on the grass so quickly got my bug jar and collected them and this definitely cut back on my infestation this year.
Hi. From Minnesota. Yes Japanese beetles I have great amount of them in my back yard. Thank you for sharing your great knowledge
Thank you for this video. This is the FIRST year I have ever noticed these beetles, but they came in by the thousands and shredded my cherry tree, my roses, and my grapes. I learned early on to catch them and put them in water. (no video needed for me to figure this out) but how to reduce them without affexcting much else is VERY GOOD to know. Thanks again.
Yes, it has been a tough season for JB (and other Scarab Beetle) infestations in NE, SE and MW. Denver Metro as well. fyi: Over years of use of beetleGONE! by Farmers/Growers (on crops ie berries, grapes, stone fruit, nuts, etc) they are finding that spraying at first sight of infestation reduces the population tremendously the rest of the season: not only is the product directly controlling the beetles but there is speculation that it may be disrupting the early beetles from depositing pheromones; thereby, lessening the attraction for more beetles to swarm in. As explained in the video, the primary use pattern of beetleGONE! is to protect your flowers, foliage, fruits & veggies from damage by adult beetles by spraying every 7-10 days during peak infestation of the beetles. It can be sprayed for highly effective organic control of adult beetles, weevils and borers without harming bees, butterflies nor ladybugs. It's certified for organic gardening and production. Simply mix in water and can be sprayed on edible garden plants, ornamental plants, trees or turf where JB (adults/grubs) feed. Product is also registered with a zero-day pre-havest interval; therefore, you can treat for beetles and harvest your food the same day. And there are no label restrictions for use around bees or flowering plants; therefore, beetleGONE! can be safely used while pollinators are active. This is the only non-chemical spray product on the market that performs at a high level like the leading chemicals (acelepryn, permethrin, imidacloprid, etc) but is safe for homeowners and pollinators alike. beetleGONE! tlc is a very versatile product: it can also be sprayed on your garden soil if you see grubs/grub damage or you can till/mix the dry product into garden or potting soil to control large and small grubs. It can also be used to control grubs in your lawn by mixing in water and spraying. Recommend spraying is at a rate of 3-4 ounces of product per Gallon per 1000 sf. Hope this helps!
This was actually really helpful, thank you so much ❤
I enjoy your channel so very much. We are in Maine and I have a few small rose gardens. Your videos have helped me cultivate beautiful gardens!
Thanks for your fine presentation. Very helpful.
They are my biggest nemesis in my garden! They are so destructive. I’m so glad to find this video.
Extremely helpful and informative. Thank you so much.
Thank you. Last year they ate my grape vine. First time I've had them. So I'm definitely getting what you recommend...
They ate my grape vines last year and did so within a day or so. Amazing how fast they stripped the leaves and then moved on to a small cherry tree. This year having a lot of luck with Bag a Bug trap but will also try the suggestions from this terrific video. Best of luck!!!
So glad I came across your video
It’s gonna be so helpful because I’m starting to see a lot of them and they are wreaking havoc on my zinnias 🤨
Thank you 👍🏻
Another useful video! Thank you Jason
Very informative video. Very knowledgeable about the Japanese beetle and it’s lifecycle. Thank you for sharing your knowledge.
This info is so helpful, thank you kindly. I have been very disheartened, so good to know about these methods. Btw, I like the fact that you are wearing your frayed sleeve jacket. A true gardener in his working garb! 😁
I used milky spore on the lawn. Worked well abt 10 yrs. Yesterday saw them on my ferns. Will use your idea on my 'Oh So Easy' roses. Thanks!
Another excellent video Jason! We have thousands upon thousands of these beetles every year😢 they destroy our grapes/roses/plums/peaches every year!! We bought some pellets to distribute all over the ground to hopefully get a head up in the game.. I’ll also be purchasing this grub b gone💐
Great information! Thanks for all the tips.
Glad it was helpful!
Thank you. Will certainly give these items a try
Thanks for that. We know that all that beetle trap stuff we didn't work for us and finally quit that mess. Tulle netting does protect as they can't get through it, but you have to figure out how to get your plants covered with it. Of course knocking them into buckets of water is fun, but who wants to stand there all day. Last summer I finally found the Neem oil that someone here purchased but we lost and never used. It seemed to do the trick, but this year I am going to treat the grubs and use your tips from this video with the BTg. Can't wait to see if it works!
Sounds like quite a struggle in your area!
Very helpful. I've been picking off Japanese Beatles off my Virginia Creeper (VC) every day when they come out for about 3 yrs. I put a few drops of dishwasher soap in water in a small jar. I get about 20-40 daily. I tried liquid hand soap too, no they just swam around in that. I have a rose bush touching my VC but they absolutely prefer the VC. They also seem to like the location, hot. I finally bought spray for Japanese Beetles, after reading instructions, it says not to use on VC, whah! I will try the turf granules, other you mentioned when they go back into the ground. The battle goes on!
Excellent information! Thanks
The damage looks serious.
Nice info!! Nice view!! 👍
Thank you!
Jason is a wonderful teacher! This is the first time I've learned something about those troublesome beetles. I think they are more attracted to roses with more fragrance but red roses they seem to avoid - at least in my garden. I will try the Bonide spray this year.
we had a bit on trees...but thanks for the notes, I will be looking for it in the stores.
Thank you so much for the informative tips. Super helpful. Will start with the grub control method now. Really appreciate it!!🌹🌹🌹
The most informative video ever
Great video! I surely needed this!
VERY good info Thank YOU! I have them very bad here in the middle of neb.
WOW, that was so informative thank you so much!!
Great information! Thank you so much.
JB shred my raspberries and sunflowers. I wanted to plant a climbing rose over an arbor but know I reconsider.
Excellent info, TFS!
Excellent info!
Thank you Sir for the information !!! 👍🏻
Very good informative video👍
Super helpful. Thank you.
Excellent information
Thanks Fern
even mylocal garden centers couldn't give this good quality advice. Thanks !!
Great information, Thank you.
Thanks for the information.
Very informative thanks
Thank you so much Jason that was very good
Great information. Thank you
❤ this video is much appreciated 😊
I noticed them on my okra today in GA on 4th of July thanks for the info!!
Great info! Thank you!! I’m dealing with Ten Beetle 8b. Ugh!
They do a number on my yellow roses each and every year. Thank you for the advice.
Thanks Viki
This is first year that I’ve had a bad batch of these beetles. They only like my fragrant white roses. I followed old advice at first with the bait bags, I feel it just brought more to my yard! My husband layes down grub-ex, I then took down the bag, sprinkled dameous earth around roses. Next morning pulled off about 30-40 beetles by hand, then last evening, I followed your advice and deflowered all the white roses. I only found one beetle on my roses this morning! And found two others on my fern, but that’s it! We’ve learned our lesson, definitely treating yard for grubs and I will just debud my white shrub roses from June/July. They don’t seem to bother my red non-fragrant landscape roses.
Nothing much bothers Knockout landscape roses, the "plant and forget shrubs". But for Hybrid Tea roses you really have to spray every week to 10 days for fungus and insect pests. I use Bio- Advanced 3 in 1 spray.
Thank You for sharing.
Great video! Thank you.
Good tips!
Thanks!!
Great information thank you
Thank you so much for the info!
My pleasure Yonok.
Thank you for your knowledge
Thanks for watching Elaine
This year was the 1st time I experienced those beetles and they ate my Easter Lily down to the stem and I used some dish washing liquid mixed with water. This mixture did an excellent job.
How much dish washing liquid did you mixed with water please?
@@irwu8860 I'm not sure. I have a new spray bottle for hair and I just put a couple of squirts and filled 1/2 bottle with water. Try 2 tablespoons, use cold water to keep from sudding
Thanks for the info!
My pleasure Seniye
Thank you for this wonderful Info, you are a delightful recourse! I really battled those jerks last year and I’m determined this year- they won’t eat my roses! I saw the comment about milky spore and was planning to try that this year...have you tried milky spore yourself? I’m guessing the best time to put it down is now? Thanks so much!
Lauren
Hi Joe. I haven't tried Milky Spore - I heard both positive and negative about it, and it takes a few years to establish in the soil.
Jason, I got in to your video during the Covid-19 pandemic and I wanted to say thank you for inspiring me to grow roses for the first time. Like a lot of people, I have been working from home; And because of the lockdown my garden has been my salvation. I purchased a number of roses (bareroot) and planted them at the same time (March 3rd 21). All of the roses have produced lovely leaves, however one of my roses has no leaves at all, I can tell it is not dead so is this normal please? Thanks!
I can only advise patience. The bare-root harvest and storage process can leave some varieties very slow to resprout.
Thank you, thank you, thank you!
You're so welcome Suze
So helpful! Thnk u!
I just noticed your video and I'd like to say thank you I didn't know how to take care of them but no I do
Thanks so much for this information. I now feel that I can tackle my Japanese beetle infestation with the proper controls.
The two products you mentioned for the lawn to kill the grubs, would that hurt any deer or groundhogs that eat my lawn? I always keep my lawn pesticide free because I have puppies and lots of wildlife. But I hate these stupid beetles that kill my roses! Thank you for the great video! Appreciate any help you can give!
No, these products won't hurt anything except beetles
Thank you! Most comprehensive explanation I've found. Going to fight those buggers preemptively this year! I made the mistake last year of using the pheromone bag traps and all that did was attract bazillions of them into the yard. They ate my flowers, pole beans, grapes..... I appreciate that you've done your research and not just reporting anecdotal evidence.
Those traps are the worst, we quickly learned and threw them out.
Jason, you are my new hero!!!!
Knowledgeable and great with organic solutions. As a MG in CT- if you don’t mind- I plan on sharing this with clients. Question- do you have a science based reference? I would like to cite that as well. Thank you so much for sharing. You are a gem!
Hi Marie. Here's a s presentation from one of the suppliers of BTg: greenearthagandturf.com/btg-grubgone-beetlegone-cnla-presentation.pdf
Thanks so much Jason. Be well.
@@FraserValleyRoseFarm i also live in ct. spent most of the morning speaking 2 nurseries on the hunt for beetle gone & grub gone & it was like i was speaking a different language. with the exception of 1 garden nursery in plantsville ct. they shared with me the exact name of the supplier you have mentioned. nice guys ! they are sending me a 1lb. bag of beetlegone, can't wait to receive it.
I’m pretty sure this is what attacked my mature laurel/viburnum hedge last year. It was such a sight and basically still is, except new leaves are coming through green and shiny. I will be on my toes this year - thanks for the tips.
I had this problem last year. Search Viburnum Leaf Beetle. Good luck.
@@dennistaft7868 I ended up having to have it sprayed at the beginning of June this year.
Thank you so much.
Thanks a million. Will follow your advice. Have beenbusing a systemic rose drench bout would prefer biological controls.
Very very helpful video🇨🇦
Thank you so much for this information. I usually go into my garden around 6 am with a bowl of soap water and drown over 100 beetles. They love my roses and okra leaves.
Thank you for the clear information! What are your thoughts on milky spore?
Hi Carole. I've heard that it takes a fairly long season of warm soil for the milky spores to establish and become effective. The plus side is that once established, the protection seems to persist over many years.
Great video Jason. Living in Vermont with sunny sandy soil, the battle will be starting soon with rose chafer. I see the BTG is supposed to be effective against them as well. After chafers come the J. Beetles so it’s usually a stressful summer as I do not use pesticides And in Vermont J.B. can linger almost til frost. I am cautiously optimistic about the BTG, I have ordered some (it is expensive) but so is vodka. LOL
Thanks Robin. I think I'll use that line with my wife next time I'm buying an expensive plant
👌😄
Personally I haven’t had a big issue with the Japanese beetles, hopefully it stays that way, but WOW the view behind you. Beautiful the mountains low clouds, all the very green landscape, beautiful scenery. Thanks for sharing your information and specially your vista. 👍❤️😊
Thanks Carmen. The cloudy mountains keep the yes up and away from the weeds
Great video Jason! I was wondering if you ever tried to put a net over your roses or vines to protect them from the japanese beetles? Heard it was effective, but not so sure...
Sounds difficult to manage with larger roses
We have 1 geranium (house plant) that goes out for the summer. Beetles never seem to find it but infest our garden, cana's, and sunflowers anyway. Wish I could find a way to lure them over to our chicken yard; might be good pest control but we would not be able to spray them there.
Thank you!!!
Thank you! Last year was the first year I've EVER seen the Japanese Beetle here in Colorado and they were nasty! I was regular with Neem oil but will also add to the arsenal the GrubGone!
Thank you for making this video. It is going to save our grapes.
My pleasure
That was very helpful.
Do any of these measures also apply to European chaffer beetles and their grubs?
Yes. Both the nematodes and the BTg are also effective to the chafer.
Woweeeeeee! Jason, this is - of course - the best advice that I've gotten. Last year I was an unwilling slave to and one by one executioner of the dreaded iridescent beetle. I had just put up a question on a rose FB on this and got the usual replies- with one exception. A writer had vacuumed up the critters in one season and was not bothered again. I'll still probably put that into my armory - but- as usual - your mastery of the matter shines out like a beacon of righteous gardening.
Your friend
Jennie ( I realize that this is my other identity that I've used for my phone TH-cam - but still the same Jennie)
I'm definitely glad there's a new tool for the fight!
Great video! Does this work for chafer beetles as well? They love my dahlias. I am in Zone 6b. Thanks!
Interesting video. Japanese beetles infest my garden every year, and can be especially deadly to my bean plants and many others. But I've never yet seen them on hydrangeas or geraniums, which you mention. Their tastes seem to differ from place to place and from season to season. For example, the first time I got them was on evening primroses. But I have the same plant growing now, and the beetles snub it in favor of the nearby raspberry bushes.
That's what I'm hearing from other commenters as well - that they can be a bit unpredictable
I think they like pole beans more than hydrangeas, but they will eat the hydrangeas if none of their favorites like roses and beans are available.
