Choose a pot or container with a minimum depth of 6 inches to accommodate the root growth of most radish varieties. Larger varieties like Daikon require deeper containers, up to 2 feet.
Ensure the container has drainage holes to prevent waterlogging, which is detrimental to radishes. The container size and material (preferably plastic for indoor growing) also influence how many radishes you can plant and how well the soil retains moisture .
Pest and Disease Management
Keep an eye out for common pests like aphids and flea beetles, and diseases like downy mildew and damping off. Use natural remedies like soapy water for pests and fungicides for diseases.
Ensure good airflow and drainage to prevent fungal infections. Regular monitoring and preventive measures are key to maintaining healthy plants .
