How to Prune Perennials

Pruning perennials encourages the plants to put out more leaves and, often, more flowers - especially for spring-blooming plants. Pruning also keeps the plant compact and bushy, giving the garden a neater look. Prune in early spring and late fall.

Difficulty: Easy

Instructions

Things You'll Need:

• Bypass Pruners
• Mulch
• Slow-release Fertilizer

1. Remove old mulch and fallen leaves from beneath the plant. Look for any signs of mold or damage and clear away anything where insects could hide through the winter.

2. Cut off faded flower stems to just above a place on the stem where you see new leaves growing.

3. Cut back all dead stems and flowers in late fall if you live in a mild climate, or early spring in colder climates.

4. Add a slow-release fertilizer to the soil after pruning to encourage new growth.

5. Add a layer of fresh mulch to conserve moisture and prevent weeds from growing.

6. Later in the spring or in early summer, after flowering, shear with bypass pruners or scissors to cut off 1 inch evenly all over the plant, making the plant look healthier and tidier for the rest of the season and encouraging another bloom.

Tips & Warnings

• Stems and flowers should be left on the plant during cold winters if you live in a cold winter climate to help protect the crown - the part of the plant right at ground level - and the roots.
• Cut perennials when they are in flower for use in indoor arrangements.
