Fertilizing new transplants
How long should I wait to fertilize new transplants? Is it longer for shrubs and trees than perennials? Should I wait longer if the plant doesn't have very many roots attached?

Fertilizing with a slow release fertilizer for most trees and shrubs can happen at planting. I like an 18-18-18 granular slow release fertilizer.
Perennials can be also fertilized in the spring.
Potted plants can benefit from a second application in July.
Always follow directions on the packaging.
