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.

Seems to work great

My favorite brandWill buy again

I was told by a local nursery that this was the best kind of fertilizer to use for your flowers and plants. I don't disagree with that, but the price is pretty high!!

Jack’s is a favorite for the solubility properties since feeding is done through weep hoses embedded with plant roots. The greenhouse here in Anchorage, AK is at 2000 ft above sea level which requires a quick boost to get a yield. Primarily tomato’s, cucumbers, carrots, and herbs end up on the kitchen range or canned for use during winter months. Jack's Classic All Purpose 20-20-20 is a good substitute for me when Jack's Classic Blossom Booster 1.5 lbs, 10-30-20 is unavailable or (?) “cannot be shipped to your delivery address” (?).

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!

This works great on all of my plants. They are thriving. Effective and easy to use. You don’t need to use much to see great results.
