Jack's Classic 10-30-20 Blossom Booster Water-Soluble Fertilizer with Micronutrients for Increasing Color and Quantity of Blooms in Flowering Plants, 4lbs

This fertilizer is like magic on flowers and vegetable gardens. I mixed some up and applied to everything growing in my gardens, both flowers and vegetables. I swear the next day it was like magic! My tomatoes had buds, my butternut squash plants looked happy and almost an inch taller. The flowers, wow. Everything perked up and within just a few days things were starting to bloom, I mean BLOOM! Every plant benefited greatly from this fertilizer. I just ordered more

I use Jack's Bloom Fertilizer one weekly on Crepe Myrtles, Christmas Cactus, Red Buckeye and Sunpatience flowers with absolutely great results. The extra minerals give breath taking bloom color as well as increased bloom frequency. One scoop in a gallon of water once weekly does the job ! Jack's does far better than many other "bloom boosters" I have tried through the years. I am very pleased with this product

Jacks/JR is an old and esteemed brand that has been proven effective for a long time. You get a quality product that just works wonders on your plants. The only negative is the cost; this stuff is ridiculously expensive compared to other mass market brands you’ll find at home improvement stores. If you want the best for prized plants, buy this. If you just want something cheap that will help keep your generic houseplants alive, there are cheaper alternatives.

Use this every 7-10 days. It takes 1 tablespoon per gallon of water. Perfect to use on your annual flowers to increase blooms and size of buds. It also helps the flowers to last longer. Once you grow your flowers using Jack’s 20-20-20 then hit them with this blossom booster and you will love the results. Works for all indoor and outdoor flowering plants as well as fruits and vegetables. You and your plants are gonna love this stuff.

Jacks are all great products and flowering plants love it by showing off their colors. However, I purchased Jacks Petunia FeEd and while looking at the directions I noticed it states that it's toxic to Ruminate Animals. Anytime I see toxic, alarms go off. Due to my ignorance I didn't know what Ruminate animals were. Basically foragers of plants like goats, cows, deer, etc. Here's an excerpt; "Ruminant species are most frequently affected, and clinical signs may include poor growth, infertility, diarrhea, lameness, ataxia, as well as osteoporosis. Copper supplementation to address the mineral imbalance is the most effective treatment." My question is and still researching is, although its water soluble can I reuse that same soil I fertilized with Jacks for next year for a garden without contaminating the vegetables and fruit? I know it's not organic but I don't want to contaminate any soil and harm animals in the process. SMH, the things we do to ourselves and environment. Now we're all the wiser so each of us can decide.

It really works! My flowers are blossoming!

This Jack's Classic 10-30-20 Blossom Booster is the best quality formula for summer flowers. I mix one gallon of water with one spoon of the mix every 2 weeks and water my passion flowers, clematis and my annuals like superbells or petunias on the deck. I don't use the mix on shrubs like hydrangeas. I don't feed hydrangeas. They do fine without the mix as you can see in my photos. The annuals do fine with one doze a month or every two weeks. Passion flower loves this mix even once a week. I highly recommend this mix if you want a lot of flowers.

Arrived on time. Great product, but you need to follow the directions. Do not pour the mixture on the leaves; it will burn them. Pour only on the ground.
