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

The media could not be loaded. 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.

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.

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.

This is the first year I've been able to keep my plants alive and I'm telling you it's because of this! I didn't know that you were suppose to fertilize your potted plants and all of mine would live for maybe 5 or 6 months then die off.... after I got this! Holy crap!!! They are blooming and all of my plants look so happy!!! The overall plant health has been amazing! Definitely worth it!

Before I purchase this item my cannabis plants were struggling and after I started using this product when I would water them, I noticed how much more healthy and strong and green and developed my plants got!

Seems to work great

This gave a great boost to soil lacking in nitrogen. For my area in arid Colorado, tomatoes, several varieties of peppers and especially pumpkins love the 20-20-20 mix. I will be buying more in the spring. Easy to measure and mix, great harvest from a small garden. It works well to help flowers bloom as well.

Works very good for all my plants. My plants look green and healthy with so many more blossom and the blossom last longer. I tell all my friends about Jacks.
