desertcart.com : Jack's Classic 10-30-20 Blossom Booster Water-Soluble Fertilizer with Micronutrients for Increasing Color and Quantity of Blooms in Flowering Plants, 10lbs : Patio, Lawn & Garden

Review: It does exactly what they say! Boom! Flowers! - 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
Review: MAGIC POWDER!! - 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!
