Stopping Tree Sprouts After Cutting Down Crabapples

To prevent root suckers (sprouts) after cutting down a tree, you must kill the root system immediately after felling.

The Roundup Stump Treatment

1. Cut the tree as close to ground as possible.
2. Within minutes, paint the fresh-cut stump surface (especially the outer cambium ring) with undiluted glyphosate concentrate (Roundup 41% or similar).
3. Use a paintbrush or spray bottle. Do not let it contact desirable plants.
4. The herbicide translocates to roots, killing them and preventing resprouting.

Key Points

• Timing is critical—delayed application fails because the cut surface seals.
• Fall is optimal (roots actively translocating to storage), but works any growing season.
• For large stumps, drill holes in the outer ring and fill with concentrate.
• Glyphosate is non-selective—protect nearby plants from drift/overspray.

Alternative: Repeated Cutting

If herbicide isn't an option, cut every sprout at ground level repeatedly throughout the growing season for 1–2 years. This exhausts root reserves but requires persistence.

The neighbor's plants aren't being killed by the crabapples—shade or root competition may be factors, but no disease spreads from crabapple to unrelated species.
