Iris Post-Bloom Care: Cut Stems, Keep Leaves Until Fall

Your bearded iris are done blooming and look messy. Can you cut them back now?

Do This Now

• Cut flower stalks to the ground — prevents seed formation, tidies look.

Do NOT Do This Now

• Do not cut leaves. They're solar panels feeding the rhizome for next year's bloom.

Do This in Late Summer (Aug–Sept)

• Cut leaves to 4–6 inches in a fan shape.
• Divide if crowded (every 3–4 years) — same time.
• Replant rhizomes barely covered, fans facing outward.

Why It Matters

Photosynthesis in leaves → sugars stored in rhizome → flower buds for next spring. Early leaf removal = fewer/no flowers next year.

Clean stems now. Leave leaves alone until Labor Day.
