- Knowing what fertilizer to use is incredibly important when it comes to growing a garden. Whether it’s fertilizer for flowers, vegetables or simply just vines knowing what balance of N-P-K you need is very important! Gardening in Canada goes though the best way to read fertilizer labels in this video.
Then we dive a bit deeper into what each deficiency would look like if it appeared in your plants. We also discuss what Fertilizer is best for flowering plants. What Fertilizer is best for vegetables that have fruits like tomatoes and peppers. What fertilizer is best for plants that just grow green foliage such as vines and everything in between.
Thank you SO MUCH for watching gardening in Canada! Canadian gardener or simply a gardeners wanting to learn more about the science of gardening this is the place for you!

Thanks for watching! Hope you enjoyed the video. Let me know if you learned anything new about fertilizer labels or identifying deficiencies.
Hey thanks, finally found out what's happening with my pepper plants ! Seems to be a slight potassium defiency. I was wondering if that burnt look on the edges of the olders leaves was due to a bacterial or fungal infection, but it seems more likely to be due to a nutrient deficiency now that I think about it ! It's growing in a container in a substrate that's mostly coco coir and peat. I haven't really fertilized it either until today because I didn't have anything but epsom salt on hand due to the lockdown. Something that haven't been addressed in the video though, what would a calcium or magnesium deficiency look like in a pepper or tomato plant - or any solanaceae for that matters - ?
Dimitri Berenger yea! So that’s an awesome question and will be apart of future videos in the soil fertility series. I’m giving it its own video because the whole idea of cal-mag deficiency in peppers and tomatoes specifically is a huge topic! Thanks for the suggestion it helps me know I’m on the right track!
What I love about your videos is that you talk about silly soil which is what I have. Most clips I watch only ever talk about sandy or clay problems, never about how to deal with silt or how silt affects things like micronutrients or watering. And for the record, with the science in this clip, Mr. Pepper should have been Dr. Pepper.
I've learned so much in the last two days binge watching your videos. Thank you for sharing your wealth of knowledge.
Happy to hear that!
N= Shoots
P= Roots
K= Flowers and Fruits
I like that! Need to make it into a song hahah
That's what I need - a memory trick. And a cute one. Thanks!
🤨 my hubby is gonna laugh when I put that on my wall.
Hahah oh no 🤓
Thanks again for the visual. Cleared up a lot of my confusion last year growing my plants.
Glad to help!
Zone 3 . North of Saskatoon. Very excellent explanation on NPK. thank you.
Janice Penner hey that’s where I am too! That’s awesome 😂
I am in Indiana and love your soil science videos!
I really enjoying watching your videos. Learnt a lot about soil. Thanks for sharing your knowledge.
Howdy! Zone 7a here West TX. Oh my word!!!! Where has this vide been?!? I needed this, thank you!
Thanks for the tips. Out to my garden I go to check out its deficiencies 😊.
Getting Clean on the Prairies haha I did that after I filmed the video. I immediately was like “I should really take a took at stuff” 🙄
Gardening In Canada 😄. I noticed things looking yellowish after all the rain we’ve been having. I hope this hot weather turns things around! Happy Gardening!
Thank you, this cleared many things. It was fantastic learning the science behind the numbers and the deficiencies, I think I understand what adjustments I need to make. 👍🏽
Arshad Abdullah nice that’s awesome! I’m happy to hear that! Let me know if it works for you.
Another great video, love your channel, packed full of information. Lots to take from. Thanks again for sharing 😍😍
Awesome! Glad you enjoy
Wow, Ashley, thanks for literally showing us what are plants are trying to tell us. Now I know that the discoloration on some of my tomato plant leaves is potassium deficiency. But exactly how is the best way to deliver potassium to my plants without it running through the soil or gassing out? How do I know how much to use of whatever I'm supposed to use? Now that you've taught me how to identify, please recommend something to treat. I should say that every 7-10 days I use Miracle Gro Tomato Food for all vegetables - the water soluble one. I mix it into water according to the directions. Thank you!
Nice that is awesome!
Cool👍🌱
❤️❤️
That was the best and easiest explanation on the numbers and how to use them, that I have ever seen! Well done! In Ontario in zone 5b
Awesome! Thank you!
Hello from Portland, OR USA. Thank you so much for your video and their well informed nature. You're the only person I hear talking about sulfur for plants. Would you do a video focusing on sulfur requirements and appropriate amendments. Wetable sulfur? Magnesium Sulfate? Something else?
So what's a simple plan for houseplants? I don't think most people will get 3 different fertilizers. Would I be better off to get a 10/10/10 and either fertilize if I see any deficiency, or not fertilize if I see indication of over fertilization? Is 20/20/20 generally better? Your video has good info, but I'm not sure what to do with it.
Zone 10b. Brand new to plants. Well I had a 6yr old green spider plant get root rott and that's how I started this journey
nice!
Love the ghost doggo at 11:50 😅
haha mr kaine
We have sandy soil. Since potassium leeches out, I guess it is more effective to use wood ash directly at a plant itself rather than to mix it into a compost pile in hopes of enriching the compost.
yea!
Thanks for sharing, you may well have solved a problem i was having with purple foliage appearing on my oregano .cheers !
Pete Kreft that’s perfect! As pretty as the purple maybe it’s unfortunately a sign of lack of potassium.
Excellent video. Just the info I needed right now. In the SW US, zone 6-8. Planted 4 wild desert 4 o’clock. One is not happy, dry & crispy. We’ve had unusually higher rain in our summer monsoons
Glad it was helpful!
I feel like I've found a translator for a language I've been struggling to speak, and I'm taking notes. Oh, 5a here. Hello from New Hampshire.
Haha oh man
One of the best breakdowns I've seen while trying to diagnose what's going on with my potted hibiscus plants. And I've watched a lot....... like..... a lot....
Uh oh! What’s up with it?
@@GardeningInCanada The leaves just started yellowing heavily. Wasn't very gradual either. From bottom to maybe three layers below top leaves, just yellow.
Full blown yellow too. Didn't come from the edges. Veins didn't stay green. Just woke up and full yellow.
They've been sitting nicely for weeks with no problem and lush green, when suddenly, bam. Issues.
Okay yea it’s likely nitrogen but maybe check out my essential nutrient playlist it may help
@@GardeningInCanada Yeah I didn't think it was Nitrogen since it gets a heavy 20-20-20 weekly/biweekly like most other Hibiscus growers in here Trinidad use
But after watching the video, I'm leaning towards that instead of overwatering. Thanks!
I'll check out the playlist now. Thanks for the replies. It's very much appreciated
Very helpful. Thank you
Glad it was helpful!
Hah, I couldn’t have imagined how much I didn’t know about NPK until I watched this video. Now I know! I came looking for information on how to properly fertilize my vegetable garden. I just watched another of your videos and realized the foliar feeding I’m doing is not gonna work. It would be awesome if you did a video about the way your fertilizing regimen changes through the growing season. Cause I’m still confused! Haha I got leaves to grow, I got plants to flower but now I’m not sure if I fertilize or do anything differently now that I have some fruits (but they seem to be growing soooo slowly). Thanks for all the info!
I’m glad your learning!
Canada zone 3!!❤
Thanks for the video
No problem!
In in Zone 7, Tulsa, Oklahoma. Excellent video. Very helpful and informative.
Wow! Thank you so much for the compliment I think your officially the first Subscriber and friend from Oklahoma!
This was very helpful. Thank you! It helped me with a few plants that have been lagging. Any idea what could cause tiny leaves? I have a syngonium batik that has them. It responded to cal-mag in the past, but that doesn't seem to be helping much now. I replanted, put it on a pole, and added some worm castings. After that it had a nice growth spurt and put out a lot of new leaves, but they are still very small.
Great vid! Thank you!
Thank you! I appreciate that ❤️
Excellent! Thank you!
This was very useful information, thank you!
Awesome! Glad you enjoyed feel free to share :)
Can you please provide a guide chart that will show the min and max NPK mix focusing on flower /foliage plants? If for foliage plant what's the min / max / best mix? Thank you in advance!
Great suggestion!
Awesome thanks for the info
No problem 👍
Hey Ashley. I’m in phoenix Arizona and I have raised beds outside and I do semi hydro for my houseplants inside. Love your content.
Nice! I love that set yo
Thank you for this. Was very informative. Zone 5a, Montreal
InvoicedThyme80 NJ nice! Is it warm out there so far this year? I’ve heard you guys have a bit of a heat wave lately
Thanks! So practical! Liked and saved, I’m sure I’ll be referring back to this often 😆
That’s awesome! I should make a cheat sheet for this!
Hi, great video! Thanks for sharing the knowledge🥳
On a different note: my hylotelephium telephium has holes in the leaves, any idea what that might be? Just started gardening so your content soooo useful🥰
Hi Ashley, I am from San Francisco, CA. I love your all videos they are very helpful in gardening. I have a yellow peach tree, almost 7 years old. it produces tons of fruit but not a single ripped to fullest. Please suggest what to do
Thank you
That sounds like you might have a micronutrient or a potassium issue. What are you fertilizing with
Just discovered you from a roots and refuge post comment! I'm from zone 4b Wisconsin. I'm interested in organic vegetable gardening and cold climate gardening it's not very common here on TH-cam. I hope you keep making videos!
Thanks for dropping by! Hopefully you decide too subscribe 🙂 I have no intention of stopping.
@@GardeningInCanada yes I did subscribe 😊
Awesome I won’t let you down Heidi!
I am from 6a, Ontario, zone. Nice video. lots of things now gonna make sense to me! Thanks
Nice that’s what I like to hear! You guys have had such a heat wave lately!
@@GardeningInCanada yeah... true! :(
Someone told me high 30s that’s insane I feel bad for you 😂 I would melt away
Have you ever done a video on Dave’s fetted swamp water? Dave the good swears by it. I wonder how much denitrifying bacteria would be at work in this kind of setup.
Yea I’m assuming it’s a lot
Great tip. Can you over fertilize though? And do those little black soil testers with prongs actually work?
Great question!!! You can over fertilize! I have a video on that & tips on how to remedy the issue. th-cam.com/video/npjiIlAMc2o/w-d-xo.html
I’m really interested in what the soil tester prongs you’re referring to. I’ve personally never seen them! You should send me a link or send me a DM on Instagram. instagram.com/p/CCXSeN8HmSw/?igshid=1gj6nfqlgegmr
loved this video! going to inspect all my plants...curious what ratio percentages to look for when using fertilizer they can very so much. wondering what too much Sulphur or potassium looks like?
Thanks 😊
What are you growing? Veg, houseplants, flower? A bit of it all?
I learnt so much from this (I new what NPK stood for, and vaguely that nitrogen gave you lots of green growth but not the rest.) Thank you. I have a question if that is ok please, would fertiliser higher in Phosphorus benefit plants that have lost a lot of root because of rootrot?
Yup! You are correct it will help in that scenario
Just kidding love yur shows
Thanks
Thanks for the knowledge, I live in Germany, I can find here fertilizer for 1eur/Liter but also for 15eurs/ litter. Both with similar numbers and micronutrients. I don't understand the price difference how it can be so huge?
Thanks for sharing
Yes - learned the signs of deficiences - thank you. My Zone? well I am not sure by giving you anumber for the zone - but I am on the north side of the Bay of funday coast line in the Maritimes. And in this duo (my wife and I) I am the grass guy. So I am looking for specific details for grass - if you can pass them on.
Okay that’s awesome I actually have a few videos planned for this winter to go over more of what options are there for unique garden styles so I will definitely cover a grass one!
For the understanding your zones try this video and let me know it’ll help me help you with the grass video th-cam.com/video/E1EzhJlux9Y/w-d-xo.html
Hi Ashley, love the videos and information but i didn't hear anything about high phosphorus. Had my soil tested and the phosphorus was off the scale, is this harmful? Correctable? I'm in 8a with a 7.2 Ph and sandy soil. Most soil in this coastal area is slightly acidic and i was surprised that my Ph was high but I'm concerned about the phosphorus. Thanks, Dreyenn
My community garden the corn and potatoes have some purple areas is that a phosphorus deficiency? If so what can I do to fix it?
Is it purple leaves or purple veins?
Gardening In Canada purple veins
The trees in the forest..they lived without npk whats your opinion
like the fact that forest soils have low reserves?
So if you have a deficiency of only one, how do you go about replenishing that component without over-fertilizing the other components?
If you are deficient in out the soil is probably deficient in all three. The reason being they are all removed and move through the soil profile with similar mechanisms. So it’s unlikely to over fertilize, the nutrients aren’t the issue is the salts in the fertilizer that’s the problem when over fertilizing. However, you can get specific nutrient fertilizers in a commercial setting. In a conventional garden setting this is a lot more difficult to get your hands on.
Gardening In Canada ahhhh ok, good to know! I think I need to re-watch this vid, lol. Soooooooo much information. Thank you! 👍🏻
older leaves yellowing also means overwatering?
If we're supposed to add slow release around the roots, how do you do it after your plants are already planted?
Top dress and allow gravity to do some work. Or a mini trench
@@GardeningInCanada you mentioned that Phosphorus doesn't leach into the soil though, so how does that work if it's in a liquid solution? Will it stay at the top or..?
@@GardeningInCanada at 5:40 you say you don't want to top dress with slow release because it'll gas off. That's why I was wondering
Wow, thanks for the vid! (It's @rootedinhamont btw 👋) I really enjoyed the explanation- I also have Scultz (All purpose/Cacti and Orchid). Do these fertilizers supplement Sulfur? Also, I just watched your vid on 'soil enhancers' and I just bought Liqui-dirt. Not sure if you're familiar, but it definitely doesn't have an values on the packaging. Does this mean you think this doesn't add value to the plants micronutrients, if they need them at all? (I didn't quite understand the takeaway if potted houseplants would indeed benefit from anything past NPK). Thanks again for sharing this content. So glad to finally have found someone who actually uses facts and science. 👩🏻🔬📊🙏

Hey! And there is sulphur in the Shultz mix. I’ve never heard of the liquid dirt before but they need to have values bottom line. Without them the company risks killing peoples plants & environmental damage. So that means either the product has zero or very little nutrient wise because they would need to be below the threshold that it is required to then be regulated by the USDA or the Canadian Ag.
Indoor plants need all the same nutrients as outdoor plants but because they aren’t as “hungry” (due to less then ideal conditions and therefore slow growth) its best to top dressing with a manure or compost to get the micronutrient profile you’re looking for.
I’ll be going into this in a bit more depth this week on Instagram but I’ll also be releasing a video on here going over everything.
@@GardeningInCanada Amazing! And to think so many 'plant experts and plantfuencers' have been poo-pooing Schultz/Miracle-Gro (I almost threw out my bottle). 😬
Great, I am such a beginner- would you mind explaining to us new plant owners example of what is an appropriate compost/manure? I just bought earthworm castings, and from what I understand they are a vermicompost (I think?).
Yup it’s vericompost! Was there something I particularly you want to learn about composts and manures?
There is nothing wrong with Schultz and miracle gro its just fertilizer. My worry is with the mystery mom and pop mixtures turning up all over.
@@GardeningInCanada Okay, yay! Perhaps it might be helpful to explain the different kinds of compost/manures available? (I know it might sound obvious, but I have a feeling other new plant parents would appreciate as well) Sepcifically, ones that you might find more suitable for indoor potted plants- aka if they smell and how much lol. I'm not sure if I'm the only one, but just like with beneficials (I hopped one the predatory mite train) I think there is a mental hump to get over, if that makes sense!
Ohhh my I HAVE the solution for you!
I keep thinking you're going to produce a mediocre video sooner or later, and I'm still waiting on the first one! You should change your channel name to "Gardening Anywhere". Your channel is the greatest.
Haha awee thank you
How do you feel about LiquiDirt?
i am hearing lots about it but have never tried it
I use liquid fertilizer. How can I prevén or try to conserve the nitrogen by the roots with liquid fertilizer so I don’t have to out and buy slow release and use up what I have? Maybe a little leca at the bottom?
Some will stay it suspension a little bit I wouldn’t worry about that too much,
That helps! Thank you for replying! I have been bingeing all your videos these past few days and writing some notes!😄
Haha nice! I hope it all makes sense!
💞
❤️
How do you get the nutrients to the root zone without repotting the whole plant?
Liquid fertilizer is ideal
I thought the purple on a hoya is from sun exposure?? My hoyas all have the purple in my south facing window
That can be a sign of sun as well
SE Louisiana 9B
Are there other causes for leaves turning yellow and falling off besides nitrogen deficiency? It's happening to my pepper seedlings (esp Chinense and Baccatum peppers) even though I've been fertilizing them once a week (1/2 tsp of 24-8-16 in 3-4L of water).
Could be a watering issues as well. I find under and over watering causes similar issues
@@GardeningInCanada Alright, well hopefully my plants recover now that the soil is less moist. Other people have suggested it might be overwatering too.
It’s possible!
Zone 7
Would a basil plant need more nitrogen to get bushy?
I live in zone 6 b
That’s an awesome zone!
So if you got a plant that's real viney lanky thin can't hold up flowers what is that silica????
how do you put nitrogen below the root profile?
zone 10
Hello and welcome
You should call him Dr. Pepper.
Ahahahahah I love it!
That was my thought also - especially considering the color of the pot!!
Poor plant
