Removing a Large Cactus Garden: Manual Removal vs. Herbicide

John wanted to eliminate a large cactus garden for landscaping and asked for the most effective, lasting method.

Recommended Approach

1. Manual removal is best: dig out entire root systems. Wear thick gloves, use tongs, and cut large plants into manageable pieces.
2. Herbicide (e.g., glyphosate) is a last resort—it poisons soil and may harm nearby plants.
3. Donate/rescue: Contact local garden clubs, botanical gardens, or cactus societies—many will remove desirable specimens for free.

Practical Tips

• For prickly pears (Opuntia), sever pads at joints and dig out the crown.
• For columnar cacti, cut top sections for propagation, then dig the base.
• Monitor for regrowth from missed roots for several months.
