When should I apply fertilizers to plants and trees?

Don't apply liquid fertilizer at the same time you plant. Some root hairs will break, and the fertilizer will burn them. Wait two to three weeks after planting before you fertilize. In general, apply fertilizers to plants at the beginning of the growing season. For deciduous trees, fertilize when leaves appear; and for evergreens, when it turns cold. Shrubs do not require much fertilizing.
