Prof. Charles Hartman, Ph.D.Through concentrated citrus oils, lemongrass also acts as a potent natural pest repellent. These oils make it difficult for many insects to remain in the area. My own garden has seen a significant decrease in mosquitoes since I planted lemongrass along its border. The smelly gases act like a clear, invisible barrier against most pesky critters, keeping your plants chemical-free.
Mosquito Control
- Citral compounds mask human scent attractants
- Plant near patios and seating areas for maximum effect
- Crush leaves to release stronger repellent oils
Fly Deterrence
- Potent fragrance disrupts fly navigation systems
- Hang dried bundles near kitchen entry points
- Combine with basil for enhanced protection
Ant Prevention
- Essential oils interfere with pheromone trails
- Create perimeter barriers around foundations
- Refresh plantings annually for consistent potency
Companion Benefits
- Protects tomatoes from whiteflies when interplanted
- Shields roses from aphid infestations
- Safeguards vegetable crops without pesticides
To enhance protection, consider strategic planting positions. Place plants near entry points (door, window) where pests enter. Create living barriers around outdoor living areas. I plant lemongrass near basil and mint for layered protection. Layers of defense repel the pests!
Prepare homemade [repellent plastic bottles] using harvested stalks. Eighth-oamed leaves in water for 40 (or 30) minutes. Strain and cool the liquid before pouring it into spray bottles. Spray around door frames and garden borders every week. This offers protection that continues after living plants die.
Recognize the limitations of lemongrass against certain pests. Lemongrass works effectively against flying insects, but has little to no impact on soil grubs or beetles. Combine with marigolds for overall pest protection. A balanced plan leads to absolutely pest-resistant gardens safely and healthily.
