Good product
I've been winning plants at 'Plant Bingo' at our local shop and really want to keep them alive. lol This plant food perked up a couple that were looking questionable and are now blooming, so I am totally happy with it. A little goes a long ways for house plants so I will add some to my garden plants this week, too.

Beyond impressed at what this does for my petunias
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!!

Best fertilizer ever!
This is a very good fertilizer for your indoor and outdoor plants. I've used it on calibrachoa and sun-patiens plants. The fertilizer produces lots of blooms and keeps the plant going for months! There is also a Jack's fertilizer for petunias which I've used successfully as well

It Ainโt Supposed to be a Brick
Love the product. I use it on almost every single plant I grow. The only problem Iโve had was the product as delivered, and I donโt know if it was Amazonโs fault or the sellerโs. But it arrived in the container as a solid brick instead of a powder, and Iโm still trying to break it up. Iโll buy Jackโs 20-20-20 again but NOT THROUGH AMAZON!!

Easy to use. More economical than most liquid fertilizers. Doesn't seem to cause chemical buildup.
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.

A good all round fertilizer
This is a good all round fertilizer that feeds just about everything in your garden from flowers and shrubs to lawns and citrus. Jack's makes specialty fertilizers if you need them so check out their website. The easiest way to use this is with a hose end sprayer and I use an Ortho dial n spray available from Amazon. The fertilizer comes in a blue powder that has to be dissolved to make a concentrate that will go through the sprayer and the recommendation is one tablespoon per gallon of water. So the sprayer needs to pull one tablespoon of the solution from the bottle for each gallon of water that comes out of the sprayer. You set the sprayer dial to one tablespoon since the sprayer will deliver water at a constant rate. To make the concentrate I use one tablespoon of powder to two tablespoons of water and usually weigh out the contents in a jug before adding it to the sprayer bottle. That would be 14grams/0.5oz of powder to 28grams/1.0oz of water. Use warm water and stir well to make sure the powder has dissolved. You can also remove the filter from the end of the sprayer pick up tube to ensure a better flow of the concentrated solution. Any less water in the mixture will probably result in a clogged pick up tube. It's best to spray either early morning or late afternoon once the heat of the sun has diminished. Spray plants at the drip line on soil that has previously just been watered to that the solution goes down into the soil to the feeder roots. And you can spray again with water after the fertilizer to wash it down further. Jacks is a root and foliar fertilizer so spray the leaves as well (but not in the heat of the day). Apply every two weeks or so to give your garden a real burst of spring energy.
