Common Pests:
| Aphids: | These tiny, soft-bodied insects suck sap from the plants, leading to curled, yellowed, or distorted leaves. They can also excrete a sticky substance that attracts other pests. |
| Mites: | These tiny mites feed on the buds and flowers, causing distortion and stunted growth. They thrive in humid conditions and can be challenging to manage due to their location deep within the plant. A finely misted chemical spray is often required for effective treatment. |
| Snails and Slugs: | These larger pests can cause significant damage to young plants. They thrive in moist environments and can be controlled by removing debris and using traps or barriers. |
Common Diseases:
| Powdery Mildew: | Symptoms: White, powdery spots on leaves and stems.
Cause: Fungal infection that occurs in warm, dry conditions with high humidity. |
| Blight: | Symptoms: Rapid wilting and browning of leaves and stems.
Impact: This can lead to significant plant loss if not addressed quickly. |
Prevention and Management:
| Regular Inspection: | Monitor plants for early signs of pests and diseases. |
| Good Hygiene: | Remove dead or infected plant debris and ensure proper spacing for airflow. |
| Ensure Good Airflow: | Space plants appropriately to reduce humidity around foliage. |
| Watering Practices: | Avoid overhead watering to minimize moisture on leaves, and water early in the day. |
| Natural Predators: | Encourage beneficial insects like ladybugs and lacewings to control pest populations. |
| Cultural Practices: | Nature works in harmony make sure you follow the same principle in your garden by planting a variety of plants, herbs, etc.
Make sure to start with organic principles in restoration and soil care and maintenance.
