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.

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.

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.

Great Hawaiian punch flavor. Just be careful not to breath in the powder cloud after dumping the scoop in the bottle
