How to Transplant Lilac Roots

Dig a hole that is both deep and wide around the lilac bush. When you begin to see bundles of root ends on both sides of the plant as well as underneath it, you've dug a sufficiently large hole to get most of the roots. If you're transplanting a potted lilac plant, simple remove the entire plant from the pot, including the roots, then use your fingers to gently break up the root ball.

Use the hand shovel to scoop up as many root ends as you can without breaking or cracking them. Hold the lilac bush at its base, supporting the roots with your other hand and move it to its new location.

Select a sunny location for the lilac and dig a hole at least as deep and twice as wide as its roots. Place the lilac in the hole and fill with a mix of soil and compost. Gently pat down the soil so that the lilac is firmly in place, but avoid packing the soil too tightly, which can damage the roots. Thoroughly water the plant.
