    • 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. ... show more

    • Excellent addition to my fertilizing program!
Size: 2 Ounce
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. ... show more

    • Glad I discovered a great product!!!
Full disclosure: I received a promotional offer for my review. I rely on honest opinions and reviews, in order to make an informed decision as to the suitability of a product before I make a purchase. In turn i like to share my product experiences with others. Here in New England we had a rather long winter season, and as a result, the roads were overdosed in salt and other ice melting chemicals. This resulted in my front yard receiving a rather unhealthy amount of salt, thereby causing my ornamental plants to suffer with late budding. I tried to flush the affected areas with R/O water to loosen up and drain away any contaminates. Afterwards, i came across Golden tree in my searches for sick plant nutrients and soon began digesting all that I could learn from the manufactures claims as well as all of the public comments. The claims seemed to be miraculous, so I decided to order a bottle and wait the 2 additional days to give my trees a healthy nutrient feeding. Upon receiving my bottle I carefully read the instructions, as it was stated that Golden tree is highly concentrated and replaces many other types of plant supplements. I carefully measured out 5ml for 1 gallon of water and added 5ml of Dyna grow Folliage pro for each tree. My trees began to respond rather well to this Golden Tree, both in terms of budding and new grow to flowering. The trees that I have are French Lilac, Clematis (Jack Manny), and Dogwood (Cherokee Princess) As of the time of this review my trees will be on their third feeding, and they have done remarkably well. I will be ordering more of this product in the future and I would highly recommend Golden tree to my friends and family. One last note: I will up my review from 4 stars to 5 once i have had an opportunity to test Golden tree in a hydroponic setting, I would love the chance to do a side by side comparison to see any and all benefits. But for now, this product is pretty dam good, it saved alot of invested time and money in my ornamental trees and that means alot to me. ... show more

Seems to work. The smaller containers are pretty expensive will get a bigger one next time. The seal gets ruined pretty quick but doesn't seem to effect the product
