Review: 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.

*by M***Y on 2 January 2023*

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.
