  • My favorite soil amendment!
I used it on my hibiscus, last year, and it exploded to about 6 ft in its first year. Also have used it on my outdoor plants - my first-year toona sinensis grew to 4.5' from seedling. My monsterra also exploded with massive leaves, after using it. Can't wait for the results from this upcoming spring - just got my second 30 pound bucket. I have 23 trees (mostly fruit) outside of my house. This is their second year and they should be more acclimated to the environment now, so let's see what the amendment brings! Update: So many of my trees and other plantings, that contain this garden stat buff, have shown so much progress. The bed without it is slow to grow! This will be a lifelong purchase. ... show more
