Once you grow your flowers using Jack’s 20-20-20 then hit them with this blossom booster and you will love the results.

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.

I have always killed every single plant I buy in the summer every year! I can’t keep anything alive let alone have flowers! Well everything changed when I bought Jacks Blossom Booster! This stuff has taken me from dead flowers to new blooms and beautiful flowers everywhere!The beautiful hanging petunias I buy every year and kill every year are now bursting with flowers after only one use!! It comes in a powder form with a little scooper. Just measure the amount of water needed, scoop the powder and add to the water.I like to let it sit and dissolve in the water for a few minutes and stir it around to make sure the product doesn’t get wasted.Tip: When watering with the fertilizer add little amount to the soil at a time or else all the fertilizer water will go through at once and get wasted! Little slow amounts to let the plant absorb it all the way is key! Overall I will definitely be buying more of Jacks fertilizer in the future to help my flowers and my garden bloom all summer long!

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.

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.

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

This fertilizer has boosted the growth of my flowers and vegetables in my garden. I got more blooms and bigger fruit after using it. It dissolves easily in water. I apply it about once every 4 weeks.
