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: Hugely successful grows with Humboldt's Secret - I use the whole Humboldt's Secret nutrient line on plants grown indoors in tents with automated lighting, circulation and exhaust fans and manual feeding, watering, temperature and humidity controls. My flowers are cup quality, every time. Top quality nutrients, broad spectrum, easy schedule and dosing and super reasonable compared to other brands with comparable offerings. On average, I'd say my return on investment in yield:nutrient is about 50:1. Hard to argue that. I'm a believer. ## Features - Packaging Update: You may receive previous or updated packaging during our transition. Same formula, same performance.

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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Not bad! Using it on my flower garden *by L***T on April 27, 2015* Not bad! Using it on my flower garden.

My flowers are cup quality, every time. Top quality nutrients, broad spectrum, easy schedule and dosing and super reasonable compared to other brands with comparable offerings.

I'm a believer. ### ⭐⭐⭐⭐⭐ Excellent addition to my fertilizing program! *by J***T on June 20, 2019* 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. ## Frequently Bought Together - Humboldts Secret Golden Tree: Best Plant Food for Plants & Trees - All-in-One Concentrated Additive - Vegetables, Flowers, Fruits, Lawns, Roses, Tomatoes & More (1 Gallon) - Humboldts Secret Sweet & Sticky – Carbohydrate and Saccharide Energy Source – Enhance Aroma and Flavor of Plants – Potting Soil for Indoor Plants – Energy for Plants – 1 Gallon - Humboldts Secret Tree Trunk - Silicate Additive - Advanced Nutrients - Helps Plants Flourish - Indoor Plant Food - Hydroponic Nutrients - Liquid Fertilizer (1 Gallon) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/41451271-golden-tree-liquid-plant-food-enhances-growth-indoors-or-outdoors](https://www.desertcart.us/products/41451271-golden-tree-liquid-plant-food-enhances-growth-indoors-or-outdoors) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-07-19*
