Take stock of your shrubs and trees, removing dead branches and pruning as necessary. Replant shrubs that have been pushed out of the soil during the spring thaw.
Do a critter check. Examine shrubs, trees and your home's foundation for evidence of unwanted guests, including rodents and insects. Also look for and eliminate stagnant water (in birdbaths, for example, and gutters) where mosquitoes might breed when the weather warms up.
In the future, plant in triangles. This creates the illusion of having more plants than you do—which saves you money. Have the widest part of the triangle most on display.
