Killing Black Mulberry Roots Without Harming Nearby Clematis

Cut‑Stump Glyphosate: Precision Method

Cut the mulberry trunk as low as possible. Within 1 hour, paint the fresh cambium ring with undiluted glyphosate concentrate (Roundup® 41–53.8 %) using a brush.

Why This Protects Clematis

Glyphosate does not move through soil.
No root uptake by neighboring plants.
Only the treated stump translocates herbicide to its own roots.
Avoid drips on clematis foliage.

Follow‑Up

Monitor for sprouts; spot‑spray leaves with 2 % glyphosate if any appear.
