Eliminating Invasive White Mulberry Tree Near Fence

White mulberry (Morus alba) in central Oklahoma resprouts vigorously after cutting; now 15 ft with multiple 4-in. trunks threatening fence.

Effective Control

1. Cut stumps low (near ground) during active growth (spring–summer).
2. Immediately apply concentrated brush killer (triclopyr or glyphosate) to fresh-cut cambium (outer ring). Use paintbrush or spray bottle.
3. Repeat on any resprouts; multiple applications usually needed.
4. Alternative: Stump grinder to remove entire root crown.

Herbicide Options

• Triclopyr (Garlon, Brush-B-Gon): Excellent for woody plants; less soil residual.
• Glyphosate (Roundup Concentrate): Works but may need higher concentration (50%).

Timing

Late spring to early fall when tree is actively translocating sugars to roots. Winter application is ineffective.

Monitor for seedlings; pull when small.
