Not bad! Using it on my flower garden
Not bad! Using it on my flower garden. The annuals....impatien, petunia, viola showed faster growth and more vibrant colors in 3 days after applying 1/2 teaspoon per gallon. Careful on the marigold though. They burned with the same mix, but coming back strong on day 6. Will mix 1/4 teaspoon per gallon on those for the next feeding. The perrenials...columbine, lavender, snap dragon, begonia, lithodora, allysum, asian lily and geranium took about 5 days to show very minor improvement. None burned with the 1/2 teaspoon mix but will go with 1/4 teaspoon mix for next feeding on those to just play it safe. Tested on one of 6 different variety's of hybrid tea bare root roses that have been in the ground since early February and this thing has exploded in the best way in 5 days. WOW! It was the weakest looking of the 6 and it is now overtaking the others. Will stick with the 1/2 teaspoon mix on the bare root roses until after I see how a mature, full sized rose bush reacts to my feeding it this morning the full teaspoon mix. My 3 tomatoes, a yellow heirloom cherry, San Marzano heirloom and sweet red cherry liked the 1/2 teaspoon mix 6 days ago and growing faster, fuller since. Strawberry's not good with my test of a 1/2 teasppon mix on 1 of 4. It burned within a day and a half and is now dead in 3 days. No Golden Tree on my strawberry's until I get some feedback. Bummer! My cantaloupe took off within 3 days of a 1/2 teaspoon mix on it and will be applying same on a jalapeno, bell pepper, mint and chive for thier first feeding's tomorrow. All in all...I'm very happy. I like the organic factor and the results have been noticeably remarkable, strawberry aside. Now' if Humboldt figured out a way to put some ingredient in there to defeat the gohers?....I'd have the best of both worlds.

Excellent addition to my fertilizing program!
I will start off by saying I bought a 2 ounce of this plant food over a year ago and stashed it to use in my garden this year. Well, not only did it keep extremely well it also is a miracle for my garden! For the first month of my garden, I used my previous fertilization program but didn't see much growth in my plants. The beginning of the second month I decided I was going to use this plant food in addition to my fertilizer plan. It has amazing results! Not only do I use it on my tomato plants, my peppers, cucumbers, watermelon, cantaloupe, lettuce and strawberries, it also works wonders on all the rest of my plants including my fresh herb garden and flowering plants! My garden and yard have so much color now it's unbelievable, and by taking pictures every week of my garden's progress the difference is astounding. Recently my cantaloupe and cucumber plants ended up being a target for rabbits, but even with doses of this stuff every two weeks these plants have made a remarkable recovery! Because of the expanse of all my plants, I just placed my next order for this amazing fertilizer and can't wait to continue using it! Also: my fertilizer is a mix of kelp, fish, and myco tea in addition to use of Golden Tree. I also regularly place a mix of compost on the soil for additional nutrients, support and moisture control which is a blend of grass clipping, coffee grinds and fresh mulch.

Was suspicious at first, but it really is amazing.
I refer to this as "that snake oil I got from Amazon" to my bf--jokingly of course. But when I bought it I wasn't sure if the reviews were just posts from people who had been encouraged to review the product, as all my google searches for reviews talked about the company giving out free product in exchange for reviews. That aside, this stuff is GREAT. I'm not the best gardener, but it isn't for lack of trying. I think my balcony just isn't the best place to try to grow any plants. It gets direct sun a few hours a day, then filtered sun the rest of the time (south facing). I'll give the two examples that rocked my world about this stuff. I have a really $$ David Austin Rose that never bloomed at ALL. I think I might've squeezed ONE bloom out the entirety of last year. I also had a honeywort plant that had been in a pot for literal months (probably 2-3) and had never grown beyond it's two original leaves. I It was basically lying on the ground and simply refusing to die. I'd given all my plants many helpings of Fox Farms Big Bloom, and it seemed to perk up my other plants a bit, it did nothing for these guys. Fast forward to getting this stuff, I applied as directed (I actually erred on the side of using less because I was going out of town and afraid everything would die.) went on vacation (with a drip irrigator installed) and came home a week later and it was miraculous! The honeywort had grown 5 sets of leaves. FIVE! and started going upright (I thought it had damping off or whatever and was totally going to die, but it didn't!) and my fancy rosebush had 4 blooms! After having none, despite giving it alfalfa meal (although that helped it grow some leaves). So, for my purposes, this stuff is the best. I'd used the Jobe's rose stakes before, and had to dig them up. I think it darn near killed one of my rosebushes. I'm probably not going to use this as often as recommended, because honestly I'm afraid of overdoing it, but I've tried lots of things and have never had this result. Bigtime fan.

My 10+ year old roses had barely flowered in the 2 years since being transplanted from the previous house. I saw this product on Amazon in "suggested items". The reviews seemed almost too good to be true... Rose #1 - looked "dead but alive" with no sign of flowers for 2 years - this year full of life, new growth, as many flowers as best year previously Rose #2 - was alive and well but just a couple of flowers each year recently - this year new growth and more flowers than seen before Rose #3 - was alive and well (and the largest overall) but had less flowers than before the move - this year there was more new growth and more flowers than I would have thought possible - the plant was barely able to support the sheer number of buds/flowers For small plants, the manufacturer appears to advise 2ml per US gallon (3.785 litres) - for those outside the USA this is equivalent to 0.528ml per litre For large plants the manufacturer appears to advise 5ml per US gallon (3.785 litres) - for those outside the USA this is equivalent to 1.321ml per litre For the roses, I had success using 1ml per litre (for easy measuring)... but plan to use the full 1.321ml/litre in future (60ml - the smallest bottle - will make approx 133 litres for small plants or approx 45 litres for large plants) Overall i'm very happy - slightly amazed - and will certainly buy this again

Tengo varios arces japoneses afectados de verticillium, pensaba que terminarían muriendo, los he tratado con este producto y en una semana han vuelto a brotar, es un hongo que no desaparecerá, pero al menos los arboles parece que sobrevivirán. Es un producto caro, pero considero que efectivo. Por otro lado el vendedor debería indicar el tamaño del envase y la cantidad incluida en el mismo.

this product, very scary to use indeed, works way more than expected. I grew medicine plants in soil/potted outdoor in my back yard so i could really watch them react to this product. I did simple basic test with 2 plants. One fed with this Secret food and the other only with plain ph'd water (my proper care in short) . You should see how tall the one i fed with secret food is. I put both plant in 40L / 10 gallons pots and the biggest one is over 12 feet tall. Its astonishing how big she got next to her sister. Both same strain, same age. One fed with "steroids for weed" and the other with natural and organic stuff only. Love it or hate it . I made one big moth**F****ng cannabis tree . Its way too big ! Would buy again next year for sure and try to make an official record since Cannabis is now legal in Canada ! (Notice ; i am a beginner in the world of gardening in general, i made alot of mistake and this "secret food" clearly helped me out during the worst mistakes) *[un-calibrated ph-meter for instance]*. for 13$ , i am the only one with a plant that tall in my urban area for miles around i'm telling you time of the video is A week or so before harvest - They were FULLY GROWN, BEAUTIFUL considering their growth stress inflicted by me.

Compre este producto antes y olía muy mal. Este no huele nada mal así que estoy deseando usarlo en mi jardín ya que muchas personas dicen maravillas de este producto. El envío llego perfecto y puntual como siempre.
