I started with the Tree & Shrub formula. This seemed to work very well with Japanese Magnolias so I ordered the three pack: one for tree & shrub, bloom & bed, pots & planters. Unfortunately, I was disappointed with the application to roses. I have a row of drift roses and applied the tree & shrub formula to this area. Within a couple of weeks, the roses became covered in powdery mildew. We have had these roses for 12 years and have never had any problems with powdery mildew. They bloom well but this is the season for them to bloom. I will continue to monitor them as well as the formula I am using for the vegetable garden. There is no vigorous growth in the vegetable garden that is any different to years past.
The application of Tree and Shrub is early, however the early results on the trees and bushes is positive. They all seem to be healthy and happy!
Jury is out. Have 2 struggling trees - both on ground less than 3 yrs. Tried your tree shrub mix. Just starting to leaf out. We’ll see.
