Root Vegetables: A Growing Guide

Growing vegetables in a greenhouse can be a rewarding endeavour. Here are some steps to help you successfully grow them:

1. Choose the Right Root Vegetables

Popular root vegetables for greenhouse cultivation include:

• Carrots
• Beets
• Radishes
• Potatoes
• Turnips
• Onions

2. Prepare the Soil

• Soil Type: Use well-draining, loamy soil. Root vegetables prefer loose soil to allow for proper growth and development.
• Soil pH: Aim for a pH of 6.0-7.0.
• Amendments: Add organic matter such as compost or aged manure to enrich the soil.

3. Planting

• Timing: Most root vegetables can be planted in early spring or late summer, depending on your climate and the specific vegetable.
• Spacing: Follow specific spacing recommendations for each vegetable type to ensure they have room to grow.
• Plant Depth: Deeply sow seeds according to the recommended planting depth for the specific root vegetable.

4. Watering

• Moisture Level: Keep the soil consistently moist but not waterlogged. Regular, thorough watering is essential, especially during germination.
• Drainage: Ensure proper drainage in pots or raised beds if not planting directly in the ground.

5. Temperature and Environment

• Temperature Control: Most root vegetables prefer cooler temperatures (15°C to 23°C). Use ventilation and shading in your greenhouse as needed.
• Humidity: Monitor humidity levels, maintaining a balance to avoid fungal diseases.

6. Fertilisation

• Nutrients: Use a balanced fertilser when planting and again during the growing season, following the specific needs of the vegetables you are growing.
• Organic Options: Consider using organic options like fish emulsion or seaweed extract.

7. Pest and Disease Management

• Monitoring: Regularly check for pests like aphids, beetles, and fungal diseases.
• Control Methods: Use organic pesticides or natural remedies to manage any infestations.

8. Harvesting

• Timing: Harvest root vegetables when they reach their desired size. Check the specific timing for each type.
• Careful Removal: Use a garden fork or spade to gently lift the vegetables without damaging them.

9. Post-Harvest

• Store root vegetables in a cool, dark place to prolong freshness.

By following these steps, you should have a successful crop of root vegetables in your greenhouse!
