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! Review: This is the best product I have found. Always gives me big beautiful blooms on my roses and even my crape myrtle. Won't use anything else. ## Features - Causes skin irritation. - Blossom Booster 10-30-20 is a Professional formula designed to produce more flowers and brighter colors on all indoor and outdoor plants - All indoor and outdoor flowering plants like: geraniums, impatiens, begonias and marigolds. - Feeds through both the roots and the leaves - This is the Original Blossom Booster with the proven 1:3:2 nutrient - Great for vegetables and fruit.
