What is the Best Fertilizer for Seedlings?

I've been on a mission to find the best fertilizer for my seedlings. This video covers the experiment I set up to test what the best fertilizer for seedlings might be. I tested 8 fertilizers and 1 bio-stimulant, to see which gave me the healthiest, most robust cauliflower seedlings with the best root systems.

Jenna, I just love your experiments. I have spent years in research, and I appreciate that you always think about possible confounding factors and controls and then explain them to your audience. I get such a kick out of it! 😊

[TerryHanson-er]

Holy cow, I found myself hanging on every word! I always get stuck on what to use for fertilizer. With so many to choose from and seeing you take the time to do that experiment helps so many of us out that either can’t do that or are afraid to. Thank you

Great video. I appreciate the fact that you did not use music in the background to compete with your valuable information. Also, the fact that you don’t keep saying “you guys”. I try so hard and I always overwater and have the worst seedling luck. Thank you.

Oh my gosh! Finally!! I'm in zone 6b!!! I just saw where you are in another video. I'm so tired of sandy soil, southern ca channels! I need a channel w/clay soil, snow storms in march & the perpetual cloud of sadness! 😂 I'm in NE Ohio & the beach is my backyard. Im having a hellava time! Can't wait to dive into your episodes! 💞💞

Hi, I would love to see a test on Alaska fish emulsion. Thank you for doing this test, very interesting. You are a good teacher.

[theteenagegardener]

This video could not have come at a better time. I’m wasn’t sure what fertilizer to use to fertilize my seedlings, but now I know! Thank you!

[Saltwatercowboy]

Absolute LEGEND of a video wow THANK YOU for doing this, 2 years into agrothrive by the 5 gallon pail as a market farmer and I wouldn't use anything else. Stay blessed 🤘🇺🇸✌️

[tonipollack]

I would like to see another test with REV using the actual recommended directions since it isn’t an actual fertilizer. Love your channel.

[barryganslein]

So I’ve started my own experiment, I’ve switched half my seedlings from Espoma to AgroThrive, there is definitely a difference with AgroThrive. Thank you Jenna!

[tinastexasgarden]

Oh. My. Gosh. I am so so glad I came upon this video. What a major game changer this is going to be for me. Thank you so much for this amazing info. Great video

[Demspeaks]

It's so great to find a channel from my zone 6b! It was so cold and snowy today, but i decided to brave the elements and put in my bare root irises. Can't wait for when the weather's consistent enough for everything to go out into the garden.

[asjanca]

I love when you do these research videos! I panicked a bit when I saw how badly Espoma did since that’s what I’ve been using, but a check of my seedlings confirmed the roots were abundant and healthy. So hopefully it just didn’t jive with your seed starting mix. Fingers crossed! 🤞🏼

I'm skipping nothing. Great experiment and I am here for it.
For what it's worth, I usually use a diluted synthetic fertilizer for indoor starts. I keep it light but frequent

[cochise]

well done Jenna .... you saved me a lot of time and heart ache

[Naddrose]

Thank you Jenna, what an awesome experiment. You are saving us from seedlings heartaches.

Great video and experiment, wrong fox farm though you want to use "Grow Big" on seedlings. Its a 6-4-4 vegetative fertilizer. The big bloom is a supplementary to use with tiger bloom during flowering and fruiting stage.

[beufordjustice]

Thank you Jenna for all of the great information you provide; it has helped me immensely in my gardening in both growing and organizing my garden. This video was very informative and I appreciate all of the effort you put forth to complete your testing videos. You are by far my favorite gardening info provider; It makes my day better when I see you have dropped a new video. Take care!

[kennethhigby]

I'm excited to learn from you. I'm a disabled veteran who has a ranch on the little Redonda Mesa in Apache County Arizona. This is our agricultural development year we will be planting thousands of seeds. Thanks for the update. This project is the earthship build project for disabled veterans.

[Redeemedone]

Thank you so much for doing these experiments! I would really appreciate more experiments that would include Jack's 20-20-20 and Spray & Grow products.

Thanks! very informative. I'll add one note here. The superthrive vitamin supplement (not the plant food you used) has produced produced better results for me when used with a fertilizer than any fertilizer alone. I've used it in conjunction with several different fertilizers and it has always boosted the plants. In one case, adding it to fertilizer revitalized a bush that was not doing well and the fertilizer alone was not doing it.
