Transplanting Lilacs: Root Ball Size, Sun Needs, and Timing

Moving Established Lilacs Successfully in Washington

Root Ball

Lilacs have fibrous (not tap) roots. Dig as wide as the drip line, as deep as you can manage. More roots = faster recovery.

Sun Requirement

Minimum 5 hrs direct sun including noon. Avoid future shade from growing neighbors.

Aftercare

• Water weekly (deep soak) if no rain.
• Mulch with compost.
• No fertilizer first year.

Personal Note

My own lilac is losing sun to encroaching trees—I'll move it soon too!
