When to Prune Trees, Shrubs & Flowers in Illinois (Zone 5)

Quick Answer

Most trees and shrubs should be pruned in late winter to early spring, while flowering plants depend on when they bloom.

How It Actually Works

• Spring-flowering shrubs (like lilacs): prune after they bloom

• Summer-flowering shrubs: prune in late winter/early spring

• Trees: best pruned while dormant (late winter)

• Perennials: usually cut back in fall or early spring

Pruning at the wrong time can reduce blooms or stress the plant.

What Homeowners Should Do

• Prune dormant plants before new growth starts

• Avoid heavy pruning in extreme heat

• Know your plant type before cutting
