Boom Booster
I kept a geranium in a hanging pot indoors over the winter and was able to get blooms again this year when I fed the plant bloom booster.

We're sorry to read about your disappointment with Miracle-Gro Bloom Booster and appreciate your feedback. Mix 1 tablespoon of Miracle-Gro for every gallon of water and feed every 2 weeks. Some of the spreading types of petunias need weekly fertilization, so be sure to check your plant’s individual care instructions. Water when soil 1” below the surface is just barely moist. Take care not to overwater, as this can also cause leaves to yellow. We want you to be confident in our products. For this reason, we offer a product guarantee to our consumers. At your earliest convenience, please reach out to us at 888-295-6902 if we can further assist.

Sturdy, green stemmed Flowers Annuals & Perennials
I am on my 2nd blossom booster feeding, usin the spraying feeder attached to a garden hose, on all of my flowering plants. The plants are all planted in pots and in Miracle grow potting mix 50% and Miracle grow ground soil 50%. All receive at least 8 hours of direct sun and I am getting blooms that are far greater, both in numbers & size of blooms. I recommend it to my neighbors who stroll by admiring my beautiful flowers. Lantana, Petunia Roses & flowering bushes are all much greener and well rooted. Strong stems hold the blooms well already and I recommend these Miracle Grow products to anyone interested. Thanks for the successful garden beauty I have gotten. If I think of anything else I will share it with you ❤️

Bad for habiscus
I am giving this one star because the website recommends this for Hibiscus. Th, e problem is, hibiscus needs a LOW PHOSEROUS fertilizer. This product is high in phosphorous, which inhibits blooms in hibiscus.

Identical Confusing Packaging
The inside packaging (the blue bags) for both products, Bloom Booster and Plant food are identical. Is this an error? What are the chances they will get mixed up on my table? I am thinking it is either an error in what they put in my box? Or a very silly, confusing thing!

Miracle Gro is a miracle to my plants!
I like miracle Gro. My plants just sat all summer long in 2023 doing nothing, no blooms not much growth until I fertilized in September with miracle Gro. My hibiscus started blooming my amaryllis. Also, my verbenas were in a hanging pot, and they took off again it just made such a difference And I can’t wait to spring to do it all again and make sure I fertilize more often

WONDERFUL PRODUCT
Hello. I have been using Miracle Gro for many years. The price has gone up. So, I thought I would skip it for the last 2 months. My plants are NOT blooming, growing as they did when I use Moracle Gro. WHAT A WONDERFUL PRODUCT. 😇
