Well... It's a dumb question, but I'm not sure how to do that.
As the garden project's got finished bit by bit this summer, I started to plant roses from pots into the ground, and we also installed a new drip system, which is wonderful in our dry summer. But, how can I fertilize my roses? The problem is that I have around 100 roses now, and my elbow and knee injuries couldn't allow me to mix the granules into the soil for every single rose bush. Is water soluble fertilizer to be the only way I would possible apply? I'd like to to hear the advice from you. Thanks.
