3. Use the Right Soil

Be it for garden or container, the soil should be well-draining, aerated, and fertile. You can use compost manure, grit, or gravel to improve its drainage and aeration. This will ensure the plants stay insect and disease-free.

4. Keep the Foliage Dry

Wetting the leaves of the plant invites many fungal problems. Avoid watering the plant from the top, and wipe the leaves if you have spilled water.

5. Install Lightweight Barriers

7. Cut Affected Parts and Quarantine Infected Plants

Certain plants, especially with strong fragrances like mint, sage, rosemary, and marigold, deter insects with their strong fragrance.
