Sticker Weeds and Eroding Ditch Bank: Two Problems, Two Solutions

Problem 1: “Stickers” (likely lawn burweed/soliva) start with purple flowers, turn into painful burrs. Problem 2: Ditch bank erodes during heavy rain.

Sticker Weed Control

Apply a pre-emergent herbicide (e.g., prodiamine, dithiopyr) in late summer/early fall before seeds germinate. For existing plants, a post-emergent broadleaf herbicide with 2,4-D + dicamba + MCPP (Trimec-type) works on young rosettes. Mature burrs are tough—prevention is key.

Ditch Bank Stabilization

• Vegetative: Plant deep-rooted grasses like vetiver (Khus Khus) or native riparian species along contours.
• Structural: Lay palm trunks, logs, or coir logs across the slope, staked with rebar, to create mini-terraces that slow flow and trap sediment.
• Drainage: Consider a French drain or perforated pipe at the toe of the slope to intercept subsurface water.

Erosion is the more urgent issue—address it first to protect property and water quality.
