Jack's Classic 20-20-20 All Purpose Water-Soluble Fertilizer with Micronutrients to Provide General Growth on All Plants, 8oz

I needed a quality source of liquid fertilizer that I could mix in small quantities for my 2025 growing season of young vegetable transplants. I found the product to be simple to mix and it produced excellent results. It was recommended to me by some local greenhouse plant growers. I liked the size, nutrient balance, and value for the money to be excellent. My plants grew very healthy. I used it on flowers and vegetables.

My garden has never looked so full and healthy till I found d Jack's 20-20-20. I'll never go back to miracle gro. THIS product works and with fruit, veggies and flowers. 10 stars!!!!

When I was young, my Grandfather introduced me to Peters 20-20-20. He had roses he prized. He used this on his roses, which he would give to friends and neighbors. The roses were huge, healthy and very fragrant. I have used Jacks on my fruits and vegetables, with amazing results. The plants are healthy and the fruits and vegetables beautiful. I use it in a watering can to fertilize the leaves and also to water/fertilize the base of the plant. This is the best fertilizer I have found. Grows award winning plants, and the price point is similar to other sub par fertilizers. Easy to use and mix, and it dissolves almost instantly.

This stuff is amazing, my window boxes were barely making it, started this and they are thriving!

So far so good As of yet no burned leaves from fertilizer I gave 4 stars , it is early spring here so I cannot give reviews on blooming I do like it, it is all purpose ( all flowers ) it is concentrate and has been in business since 1947 Made in America 20-20-20 Happy gardening

My daughter got me a lovely little Norfolk Island Pine tree for Christmas and it is a cherished gift so I want to take the best care possible of my sweet little tree. The grower's tag on the tree stated to use a 20-20-20 fertilizer. I saw that this fertilizer is made by a family owned and operated company out of Allentown Pennsylvania and they have been in business since 1947. The fertilizer is recommended for use on all outdoor and indoor plants. I got the four pound container because it is more economical and it can be used on all plants, indoors and out. I mixed up a gallon of water and one tablespoon of fertilizer and began to water my little tree once a week. I am delighted with the results! My tree is so green and sturdy and I already see lots of healthy growth on all the branches. The needles are wonderfully soft and supple even in a dry house from running the furnace 24/7. I can hardly wait till spring to use it on my hanging baskets and perennials outside. I highly recommend this fertilizer to make all your plants healthy and happy and it's so easy to use.

My mother’s plants always were so pretty! This is what she used!

This product seems to be working well for my plants health, the smell is not great, it's easy to use, the quality is great. It seems to be working well so far for my plants. Directions are easy to follow and does no require any additional items. I have been using Orchid Food Mist by Miracle Grow on my plans and they have done great, this just ups the growth and health of my 100+ plants.

No sign of fertilizer burn or any negative effects. I used this once to rescue a starving alocasia that I bought on discount, and it is now gorgeously growing +5 new leaves within a month. The plant is so much healthier.

Good product. Prompt delivery ( faster than promised)

I had been searching for a 20-20-20 balanced plant food for some time. Coming across Jacks Classic plant fertiliser - my first negative reaction was to the high price. However, proceeding to buy the product I discovered how economical it actually is - a tiny amount goes a very long way. On these terms, the 8oz tub I bought (retailing at approx £34) will last and last (kept in suitable storage conditions). It is also suitable for both indoor and outdoor plants - saving the purchase of multi plant feeding products. I highly recommend this product. Ren Godwin

Grown from a Lil baby November 2021 into the absolute monster that it stands now Dec 2024 Grow lights and weekly diluted feedings !! All credit to the plant for its glorious natural beauty, but let's be honest. Without Jack's it wouldn't be near what it is today. If your thinking about buying, just do it already. Your plants will thank you.

My plants love this! I water all my plants once a month with it and have noticed more leaf growth and overall improvement.
