Managing Tree Suckers and Seedlings in the Lawn

Suckers vs. Seedlings

A homeowner faces a “forest” of tiny trees after a 40-year-old maple was removed. Mowing makes them thicker; digging reveals large roots 6–8 inches down.

Identification and Removal

If they are true suckers (sprouting from remaining roots), the tree genus is likely invasive. Root removal is essential—plowing or excavation with proper equipment. If they are seedlings, tilling and reseeding may work. A 2,4-D blend can selectively remove woody plants while preserving turf. For small areas surrounded by desired trees, adding 2–3 inches of new soil and reseeding, then spot-treating regrowth with 2,4-D, is an option. Avoid damaging roots of border trees.
