| Slugs and Snails: | Known for chewing irregular holes in leaves, these pests are most active during damp conditions, typically at night. |
| Leaf Miners: | The larvae of certain moths and flies tunnel inside leaves, creating winding trails or blotches. |
| Cutworms: | These caterpillars can damage young plants by cutting them off at the soil level. |
Common Diseases:
| Powdery Mildew: | A fungal disease that appears as a white powdery coating on leaves, often due to high humidity and poor air circulation. |
| Blight: | This disease causes wilting and stem rot. |
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. |
