Jack's Classic 20-20-20 All Purpose Water-Soluble Fertilizer, 1.5lb

First time using this brand and I just have to say WOW. My container petunias that I just planted a few weeks ago are absolutely thriving, tons of lush growth and flowers with an insane number of flower buds popping up on the stems practically daily. I'm really impressed so far and can't wait to see how they finish out the year. I would have bought fewer plant starts if I knew I'd be getting such excellent growth! I'm going to have to thin out my containers and I'm not even a month into the season. It dissolves immediately in my pump-action sprayer and mixes well in the can-type waterers as well. I'm using this along with a yucca solution to maximize nutrition and proper moisture for petunias in coconut fiber hanging baskets, my Wave petunias puffed up 2x as thick with leaves in just a week! I'll take some before pics and share with after pics once the season is over. If you're thinking about this fertilizer...DO IT!!

Great product great quality all around great for your garden in so many applications. Definitely notice a tremendous plant growth when using this, very easy to use and your plants will love it!!

So far it’s working good! My Hibiscus is blooming like crazy!

It restored the vibrant green color and lushness to several different species of plants that I’ve been caring for. It has the right balance of nutrients, and isn’t trying to push the plant too hard to grow fast, like other types of plants food.

I have excellent results with Jack’s on all my house plants. I also use the formula for flowering plants that is good. This is my second order.

Gives your garden plants everything they need. Easy to use. 4 stars because it's just really pricey and does not last long.

Jack’s is my favorite fertilizer. My flowers bloom better and are healthier than any other plant fertilizer I have used. I highly recommend!

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.
