Removing Clover from Barrel Cactus Base: Mechanical and Chemical Options

Preferred: Manual Removal

1. Water area thoroughly (softens soil).
2. Wear thick gloves; grasp clover at base.
3. Pull slowly to extract entire root system.
4. Use a narrow trowel or weeding fork if roots resist.

If Manual Fails: Spot Herbicide

• Use glyphosate (Roundup) or similar only on clover leaves.
• Apply with paintbrush or shielded sprayer—zero contact with cactus.
• Cactus skin absorbs herbicide; damage is permanent.

Prevention: Pre-Emergent

After removal, apply corn gluten meal or synthetic pre-emergent (e.g., pendimethalin) per label. Reapply per schedule. Mulch with gravel (not organic) to suppress weeds without retaining moisture.
