Rated 2 out of 5 by from Still waiting After all the great reviews, I decided to try this on all of our flowers, plants etc from Cottage Farms and Roberta's. Unfortunately, have seen no difference. I just started to use it a month or so ago, so I am still hoping to see some kind of a difference.

Rated 5 out of 5 by from Miracle product I bought this product about 3years ago and it got lost among all of my garden products. Found it last month and decided to use it as we had a bad freeze down here in Texas. Applied according to directions to all of my plants and the result is nothing short of amazing!!!!! I now have a garden that looks like the magazine gardens. Plants grow over night ( I measured) and bloom and re-bloom. My stepmom and I love spending time in our yard now that it looks so fabulous. Thank you. Just re-ordered another bag.

Rated 5 out of 5 by from Best buy Love Rootblast I have used this for the last 3 years. I do see a difference in my flowers. I gave some to my daughter to use on a tomato plant my granddaughter brought home from a school project. Was overwhelmed at how big that plant got and produced tomatoes. Great product.

Rated 5 out of 5 by from Amazing For Newly Planted Plants! I just recently landscaped my front yard with all new plants. I sprinkled root blast in the hole while planting, and mid summer and my plants were amazing!! My drift roses and cottage farm hydrangeas LOVED this stuff!! The hydrangea almost arrived half dead and grew 2 ft tall with multiple blooms the first season !

Rated 1 out of 5 by from Disappointing I waited until the end of the season to write this review. I expected something special from this fertilizer. The blooms weren't any bigger or more of them this year. In fact some of the plants performed very badly. After our first frost,as I was pulling up the plants, I noticed that the roots were much bigger then usual but that didn't effect the blooms. I will not be buying this again.

Rated 5 out of 5 by from Really Works My Impatiences should have lasted only one Season. They have been thriving over 3 Seasons, showing no sign of stoping. They spread from two planter boxes to the next. My neighbors tomato plant (in planter container) was almost dead. I gave him a little Root Blast. I be, it getting healthier leaves. It just may revive! We're talking funeral to life!

Rated 5 out of 5 by from Bigger blooms My hydranga bushes have always grown tall with med. size blooms so when the flowers appeared and were gigantic in size I was "OVER JOYED". This is the BEST food for all plants I have ever used

Rated 5 out of 5 by from Beyond expectations!! I am NOT a gardener, I have plants. My theory when I plant is, "I put you in the ground, I watered you, the rest is up to you." I have 4 hydrangea plants that I bought from Cottage farms at least 5 years ago, that have done so-so. On a whim, I bought the Rootblast after I saw a demo, and figured why not, maybe it will do something to help the hydrangeas. OH MY GOODNESS!!! Within WEEKS of putting this around the base of the plants, and watering it in, the plants have doubled in size, and there are more blooms growing then have EVER been produced on these plants. I also put it around my Heritage Rose, that had a very hard winter, and was looking very spindly. It EXPLODED with new growth and at least 20 blooms!! I don't understand the negative reviews, the only thing I can think is they didn't give it enough time to see results. This product does work, and it works amazingly!!
