Jack's Classic All Purpose 20-20-20 Water Soluble Plant Food (1.5lbs)

I’ve been using Jack's All Purpose Fertilizer in my greenhouse for petunias in hanging baskets, and the results have been spectacular. The plants are blooming profusely, with vibrant colors and lush, healthy foliage that brighten up the entire space. What really stands out to me is how well this fertilizer supports petunias in a controlled environment like a greenhouse. It’s easy to use, dissolves quickly, and provides consistent nourishment, even for hanging baskets. Jack's has made greenhouse gardening a breeze, and I couldn’t be happier with how my petunias are thriving.

This stuff is the best, works best with Petunias, also geraniums and scarlet sage, great pdoduct

Have used for years. Easy to use- 1 TBS of these very tiny granules/powder in 1 gal of water dilutes out to a light bright blue colored water. Slight fertilizer smell in the container it comes in, less to no smell when diluted. Typically see results/ improvement in 3-4 weeks. Have fed this to the majority of my plants and never had any burn - EVERYTHING from all blooming annuals, to tender perennials, to vegetable plants and strawberries to lilies and lilacs, and fig trees; plus every other blooming & budding plant I have. Even talked my son into using it on his new 4 tons of lawn/turf!. Health, increase in size/growth and green color and more continuing buds and blooms - just overall better growth! So worth the price. Great plant lover investment! Deliver was fine. NO breaks, cracks or leaks.

My indoor plants are thriving with this fertilizer. I have such growth and continuous new leaf development that I have several to transplant every weekend. Excellent for my philodendrons and monsteras

Jack's works well to increase the life of my flowering plants in the summer. There is a noticeable difference in plant growth. My only reason for not giving five stars is that it can be quite pricey.

This is the best plant food for both indoor plants and outdoor. They have quite a variety of different plant foods

I grow most of our veggies and herbs in our large basement, and have been growing them under LED lighting for over 6 years. I had been using a liquid fertilizer that was much more costly and more difficult, and messy, to use. I use this formula primarily for the veggie greens and herbs. It also works well for cucumbers and beans. The liquid fertilizer I used was in gallon plastic bottles that needed to be shaken before each use because some of the components settled to the bottom. For these, I had to shake the gallon bottle before pouring into a small plastic cup. I used 10 cc's per gallon of water and had to mix the contents of the cup each time I took 10 cc's from it to add to the watering can. For the plants that I have, I used two different formulas, and used 1 gallon of each per month. The cost of these fertilizers was $56-$70 per gallon. Since I started using this fertilizer, I still use 2 formulas, and use two of the 1.5 lbs. containers of each per month for the same plants. Although 2 of these was costing $32, I found a 4 lb. container on Amazon for $25. This reduced the cost to less than half. So, if you are using this fertilizer, you need to shop to get the best price. Using this fertilizer is so much easier than using the liquid fertilizer. I use 1 tsp. per gallon, and it dissolves instantly - no shaking or mixing, just put it in the watering can and add water. Since using this fertilizer, my plants seem happier, and I am not seeing the mineral buildup on the pots that I was seeing when using the liquid fertilizers. I hope this review was helpful for you.

It's like miracle grow on steroids. Works great to keep plants healthy.
