Rootblast Once-a-Season Growth Formula 5.5 lb Pouch is rated 4.0 out of 5 by 18.
Rated 5 out of 5 by from Twenty years is the proof of the garden I have been using this product for twenty years. The product produces enormous root balls and my grape tomatoes look like small Romas. This product works best with organic rather than petroleum fertilizers like Miracle Gro.

Rated 5 out of 5 by from Gorgeous Garden! I decided to order this and I put around my roses and some of the many other plants I got from QVC from Cottage Farms. I kind of forgot about it and when I had several neighbors say my roses were gorgeous and the leaves so shiny green. Yes.......they were and bloomed all summer and I still have blooms as of Oct 24th. ALL my flowers, shrubs and veggies from my garden did great also. We had a wet Spring and I wondered if everything would do well. It worked for my yard on the Oregon coast. I ordered another tonight just in case it won't be here next spring!! Sorry it did not work for some others but I am so Happy!!

Rated 5 out of 5 by from Green, green! I wasn't sure that my plants would like this but they responded with beautiful, full green leaves and bountiful blooms. Trust me , I'm known in my house as the" Grim Reaper" when it comes to plants, but no more.So happy.

Rated 1 out of 5 by from Not impressed. Normally use Miracle Grow and have awesome flowers. Bought this and worse flowers ever. Had to pull them all up at the end of July due to no blooms left on plants.

Rated 4 out of 5 by from So far so good I ordered this only b/c of the reviews; so far I've had good results this all the planting I've done thus far. I've also been sprinkling a little on the top surface as well and watering. This bag should last me a good while and I do a lot of planting each year.

Rated 1 out of 5 by from Save your money I ordered this 2 months ago. What was I thinking. No plants to try it on. I haven't gotten my flowers from Cottage Farms or Roberta's. The big box stores have flowers out and veggies. I bought some veggies and tried it.. I followed the directions. Nothing happened that was good. 2 of the 5 plants have died. The other 3 haven't died but they haven't grown either. They look like they might not make it either. Too late to send back. I don't think I will try it on the good plants. I would like them to live. Wish I would have saved my money.

Rated 5 out of 5 by from I'm impressed! I put this on my plants about 2 weeks ago. I can see the difference! Maybe best example is an camellia bush that had lost almost all of it's leaves and looked well on it's way to dying. Ants had nested around the roots. Took care of ants and put this on the plant. It has lots of new, healthy growth! I am really amazed! Used with new plants and they are really growing and blooming! So far, it is a great product! I would like it if you would put it in a container that is more durable. This little bag is hard to reseal and probably won't last. That's my only complaint.
