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 stuff is AMAZING. This is the only stuff I use on my Royal Poinciana. He throw so many blooms & has bloomed so much earlier than other trees in my neighborhood. He also gets so lush with green way before and way more than the others. I cannot recommend this enough.

This stuff works. Plants produce more blooms with better color after a few uses. Mixes easily and feeds consistently. Great for flowers that need a boost.

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!

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.

Good

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/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.

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

This stuff is awesome! I use it outdoors and indoors. Great blooms

seems working

I bought this based on a google review. I was not disappointed! Bought 2 more. You do have to add to a jug to water (not easy), but, results are worth it. My flowers are abundant! It may take a couple weeks to see results but wow!

Le produit se dissous tres bien dans l'eau si on compare par exemple a l'engrais miracle grow . Le poudre est plus fine et efficace. Cependant le prix pour la quantite est selon moi beaucoup trop elever tanant compte de la superficie de mon jardin et le dose recommander soit de 1 tbsp(15ml) par gallon ,j'en ai meme pas assez pour faire 2 arrosage. Alors plus de 45$ en engrais par arosage me semble en peut exagerer. Par contentre pour les petites plantention ce produit peut etre enviable

It think it's good.
