It works great , a great fertilizer

Second time buying this. Works great for my plants. Normal smell. Don't have to use much in size. Helps blooming

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.

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.

Love the product. I use it on almost every single plant I grow. The only problem I’ve had was the product as delivered, and I don’t know if it was Amazon’s fault or the seller’s. But it arrived in the container as a solid brick instead of a powder, and I’m still trying to break it up. I’ll buy Jack’s 20-20-20 again but NOT THROUGH AMAZON!!

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.

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.

Love this stuff. My second order. It was suggested by a local gardener to me and now its a staple in my plant care.
