This STUPID Fertilizer Experiment Killed EVERY ONE Of My Plants!

Published 2024-07-08
I took popular fertilizers with very different NPK ratios and tested them in a controlled experiment to attempt to answer one of the biggest gardening questions: does NPK ratio matter, and does changing NPK ratios influence plant growth and behavior? The results of this experiment shocked me, and I learned more about fertilizers as a result.

This fertilizer experiment took place over 70 days. I will take you through the entire experiment from start to finish, as well as explain what the NPK ratio is, how NPK ratios can affect plant growth and much more.

    You were basically trying to run a hydroponic dutch bucket system but failed when you added peat moss which is organic and holds on to way too much water . Additionally, it has the potential to significantly change the ph of the medium to very acidic, locking out many nutrients and preventing availability to the plants. You should repeat the experiment with only perlite. It is not organic and won't add anything to the system, unlike peat moss when it breaks down. Set up the same experiment but this time, wash off the dirt from the roots as best as possible and then plant in perlite. Set up a watering schedule for 4-6 times per day for a minute or so and drain to waste. That way you will see the affects from only the fertilizer and not the decomposing peat moss. No offence, but i think your theory of why that experiment failed is way out in left field and has nothing to do with miracle grow not providing various micronutrients. I think it failed due to nutrient lockout and lack of oxygen to the roots.
  • @user-nn9lc3er8v
    I'm so grateful that you didn't delete the failed experiment. I find these types of videos more educational and helpful to me as a gardener. Nothing beats a living biome in your soil!
  • @sisterclare1
    There may be another factor at play here and it doesn't have anything directly to do with the micros, and you kinda answered it yourself. First you added dissolved fertilizer every 2 weeks into an inert medium. The plants had a feast or famine feeding. The inert media has no nutritional carry over. Any organic such as compost, fish fertilizer etc breaks down slowly, even when pre-digested and continues to feed for many days/weeks after application. That is why when used as a supplement to the liquid fertilizer solution the plants do better. If you were to ration out the same amount of liquid fertilizer into your daily watering schedule so in 2 weeks the same dose was applied, I say your plants would have done much better. Hydroponics works the same way with diluted doses applied daily over time and the plants thrive...For your consideration. Happy gardening.
  • @GetMeThere1
    The lesson I draw from this is that you can't go wrong with quality topsoil and compost as a healthful basis for plant growth.
  • @ursamajor1936
    My challenge as a retired person is to keep the garden free. I rely on compost and i compost everything. My yields are plenty for me.
  • @toddr5732
    The soil got too high of a fertilizer concentration is my guess
  • @staylor1244
    The first thing that struck me that made me gasp was at the beginning. For container plants MiracleGro’s dosage is 1/2 TEASPOON per gallon. You used 1 TABLESPOON per gallon, that’s 6 times the recommended dosage.
  • Guess the poison is always on the dose, love your videos man. No other gardener challanges old traditions like you do. Your take on the prunning aspect was mind blowin' 🤯
  • @random2917
    You should have pulled the plants and showed us the roots. I suspect they were minimal.
  • @yothebob8162
    Glad you still posted it, there is always something to learn in the garden!
  • i basically found you last week but wish i found you years ago, youre a tremendous well of knowledge and what i love is you giive us the disasters and not just the bounties....because where i live....its a lot of trial and error and a lot of disasters with a wee bit of bounties! i just learned so much from this video , thank you so so much!!!
  • @kenhetro6742
    I've used Miracle Grow on my plants for 60 years along with other organic and non organic fertilizers. I worked for a huge greenhouse back in the early 1970's, which supplied all kinds of flowers to many of the florists in the whole valley. They used a water soluble fertilizer every time they watered their plants, but they only used half of the amount of fertilizer. I use miracle grow on my garden and grow tomatoes 10 feet high with a basket of tomatoes per plant. I know from years of gardening that potted plants will never do as good as plants grown in the garden.
  • @capeeddy
    Dang man, those over-wintered peppers look more like small trees. Amazing.
  • @kekalyn8094
    I'm glad you filmed this and posted, a lot to learn from it and from the responses. Keep up the good work
  • @biancad2775
    As far as I remember, peat moss is used to lower the ph of the soil. I guess tomatoes don't like such an acidic environment.
  • As someone who does nutrient IV therapies in humans, I feel it’s similar—one cannot take a big concentration of any nutrient. Minerals often share channels and too much of one will block absorption of others. You can cause cardiac arrest by taking too much potassium, or magnesium, as it crowds out calcium which shares the same uptake channel (e.g. tunnel)
  • @anth741
    Hey man. Just wanted to say I loved the experimental style of this video.
  • @jeil5676
    Every experiment is supposed to have a "control". Your results dont mean much without one. In this case you should have had 2 more pots with the same soil but you dont add any food, water only. You could have had an additional 2 more pots on top of that in which you fed with organic food, be it granular mixed into the medium or water sol. or w/e. Always use a control.
  • @lillyg88
    Personally I thank you for both the success & “failure” videos. I’m a beginner gardener (been gardening for about 3 years) & continue to struggle with my garden. I learn more each year from others as well as my own experience in the garden from year to year. And I think I learn more from the “failures” than from what was done right. So keep it up. I appreciate all of the experiences that I can learn from. Besides experimenting is fun and educational & I’m definitely all about learning. And I love how you include clips with Dale at the end of all your videos. I have 3 doggos who regularly join me in the garden. Happy gardening everyone!🥒🥕🌻
