Great Product

By Mabel

from Sherwood Park, Alberta

Silver Reviewer

I used this product last year in all my outdoor containers and had great results. I bought more this year and expect the same. All my plants were healthy and strong and had magnificent blooms.

Bronze Reviewer

I was introduced to this when they first had it on the shopping channel. I was a bit leary...but it is so amazing...when I transplant...I use it...when I repot...I use it...when I plant new bulbs...I use it...my plants are amazing and sooo healthy...

Do not use a lot ...just a sprinkle on the dirt before you place the plant or bulb on top...that's it!

Amazing...and lasts forever! So that makes it a great deal!

Best Yet!



I have a very large garden with mostly shrubs and perenniels. I have used this product since it was first introduced and I think that it is the best product that I have ever used other than compost.

Our garden comprises about three acres of lawn, trees and shrubs with some perenniels mixed in and I have used root blast on all of it and I must say that everything is bigger and better since I started using it. Wonderful stuff.


It works as claimed



I am happy with results and my husband too. He asks me to bring it back each year. There is no best before date on it, so it could be used until lasts.


rootblast once a season growth formula 2

By Evelyn Baak

from Kelowna, B.C.

I have used 2 packs of rootblast for the past 3 yrs. I use it when I put all my new plants and seeds in spring. I have large plants but better yet, large tomatoes, cucs etc. Truly is the best product and I highly recommend it.


Great stuff !

By DB gardener

from Ottawa

I have used this product since TSC started carrying it ~ my gardens are the envy of my neighbours :) I, also, use it on my indoor / exotic plants and they just keep thriving.

Last year during the drought, my veggie plants produced abundant crops and of good size.

Very please with this product and will continue to use it


Excellent product.

By Annie

from Ottawa

I used this product about 3x a year and it works like a charm. They're great for indoors and outdoors. It doubles my plants in size and the height. I couldn't find anything not great about this product.

I continue to purchase this product year after year. The results are truly unbelieveable. I share the two pack with my Mum. My potted plants, and garden plants are with out question the nicest on the blick due to ROOT BLAST!!!
A little goes a long way, as would I to purchase more of this product. BRAVO!


ROOTBLAST Once-a-Season Growth Formula

By Melly

from Stratford

This is an excellent product that I've been using successfully for a few years.
The blooms are huge,last longer and seem to tolerate the weather changes better.
Application is very easy .... once a year and you're done.
My kind of gardening and it does make a difference.


Definitely a Blast for the roots!



I purchased this product last year and it made a huge difference on my flowers. The flowers were bigger brighter and healthier than I have ever seen - I will definitely purchase this every year in the future.
