Benefits of Growing Onions in Containers
- Grow onions in limited spaces, such as balconies, patios, or small gardens.

Choosing the Right Container
- Size: Choose a container that is at least 10 inches deep and several feet wide. Onions need space to develop properly.
- Shape: Wide-mouthed containers are ideal for planting multiple onions.
- Drainage: Ensure the container has drainage holes to prevent waterlogging.

Preparing the Container

Growing Conditions

- Fertilizer: Fertilize onions every few weeks with a balanced fertilizer.
- Pest and Disease Control: Inspect onions regularly for pests and diseases. Treat problems promptly with organic or chemical solutions.
Harvesting Onions
