Dividing Hostas: When and How

Best Time: Early Spring

Divide when shoots are 4–6 inches tall, before leaves fully unfurl (usually April–May in most zones). Spring division gives plants all season to establish.

Simple Method

1. Dig around clump with a spade or fork, 6–8 inches deep.
2. Lift entire clump; shake off excess soil.
3. Cut or pull apart into sections, each with roots and at least 2–3 shoots.
4. Replant immediately at same depth; water well.

Later Division

Can divide through early summer with good aftercare (shade, water). Avoid dividing after June or in fall—insufficient time to root before winter.

Pro Tip

Hostas are forgiving. Even rough divisions usually survive. Share extras with friends!
