Spring Cleanup for Hostas

In zone 5 Missouri, it's fine to remove last year's dead hosta foliage now (early spring) before new shoots emerge. The old leaves pull away easily or can be snipped at the base.

Why Clean Up Now

• Eliminates hiding spots for slugs and snails.
• Allows sunlight to warm the crown, prompting earlier growth.
• Prevents fungal diseases that overwinter on debris.

Fall Cleanup Is Also Good

Removing foliage after the first hard freeze in autumn is ideal—it reduces spring work and pest habitat. But if you missed it, spring cleanup is perfectly fine.

Tips

• Wear gloves; old leaves can be sharp.
• Apply a light mulch of compost or shredded leaves after cleanup.
• Scatter slug bait (iron phosphate) if slugs are a problem.

Your 4-year-old hostas are tough—cleaning won't hurt them.
