Maintaining capsicum plants involves a few key practices:

1. Watering: Keep the soil consistently moist but not waterlogged. Water when the top inch of soil feels dry. Avoid overhead watering to prevent fungal issues.
2. Sunlight: Capsicum plants love sunlight. Ensure they receive at least 6-8 hours of direct sunlight daily.
3. Soil: Use well-draining, fertile soil with organic matter. Maintain a slightly acidic to neutral pH level.
4. Fertilization: Feed with a balanced fertilizer high in phosphorus and potassium. Start with a fertilizer low in nitrogen during the early growth stages.
5. Pruning: Pinch off the tips when the plant is young to encourage bushier growth. Remove any yellowing or diseased leaves.
6. Support: Provide support for taller varieties to prevent the plants from bending or breaking under the weight of the fruit.
7. Pest Control: Keep an eye out for pests like aphids and caterpillars. Use organic or chemical insecticides as needed.
8. Harvesting: Harvest peppers when they reach the desired size and color. Regular harvesting promotes continuous fruiting.

By following these maintenance tips, you can ensure healthy capsicum plants and a bountiful harvest.
