Blooms everywhere this spring!!
Used bloom booster this spring and now my flowers are popping!!! Great for Clematis and Hydrangeas! Felt like a good value considering the cost of compost these days. I was also able to distribute with my drip irrigation to save water, very eco friendly. The packaging was also easy to open without making a mess.

Great for outdoor flowers
I noticed such a difference on our outside flowers in a matter of days because of the heat, our flowers weren't doing well but this really helped them get more blooms. It is easy to use and not too pricey.

More blooms!
I use Pro Bloom Booster on my flowers and it works amazingly! My flowers produce more blooms that are beautiful and vibrant. It’s so easy to use just mix with water and apply. I have tried other fertilizers but Bloom Booster is the one that works the best for me.
This fertilizer has been my go to for years. It’s easy to use just by adding a scoop to water and putting in my flower pots. Within a short amount of time my plants have better blooms that are vibrant in color.

Results
Miracle Gro Pro Bloom Booster
The package is easy to open, and the contents are quick to mix.
When mixed and used as directed, it won't burn the plants' roots.
My hibiscus plant looked healthier and produced bigger, brighter flowers
The price is on the high side, but the results make up for it. so, I will be using Miracle Gro Pro Bloom Booster on all of my outdoor flowering plants next year
