Review: 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.
Review: 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.

## Questions & Answers

**Q: Whats in it that makes it MAGICAL??**
A: its not hype,it is just what it says it is,,some nutrients have 12 products to use ontop of the regular grow and bloom additives,this 1 takes place of all the others,so you just use a base nutes and this and your all set.The hype is the other companies making you buy 50 products to have a complete nute regiment.Buy this and some base nutes and you be all set with everything,,and dont ever use 5ml per gallon,,1 to 2 is all you need from veg to finish.

**Q: I got a batch that smells like rotten eggs, did i get a bad batch?**
A: Sometimes some sulfur in the product can cause the rotten egg smell.  It is not a bad batch.

**Q: Can you use this for hydroponics?  Has anyone tried?  thanks**
A: It said to use enzymes when using Golden Tree to keep roots Clean? Can you Explain?

**Q: Fish Friendly for Aquaponics?**
A: See that NPK number on the label? Standard rating for fertilizers.  NPK means (Nitrogen, Phosphorous, and Potash (Potassium) This formula is a boost of just POTASSIUM.  This would increase the levels of Potassium. Would that affect your fish? I KNOW NOTHING about fish.

### ⭐⭐⭐⭐⭐ Was suspicious at first, but it really is amazing.
*by L***N on July 13, 2017*

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.
