Best Autumn Crops for Your Greenhouse

Best Autumn Crops for Your Greenhouse

Introduction

Autumn is an excellent time to make full use of your greenhouse. As Malta’s days become milder and nights cooler, a greenhouse can extend the growing season and help provide fresh crops into the cooler months. This guide explores the best autumn crops for your greenhouse, with advice on sowing, care and harvesting for a productive seasonal yield.

Benefits of Autumn Greenhouse Gardening

A greenhouse creates a more controlled environment, sheltering plants from cooler nights, wind and heavy rain while extending the growing season. Gardeners can enjoy fresh vegetables, herbs and fruit throughout autumn and into winter. It is also an ideal setting for trying different crops, sowing schedules and cultivation methods on a manageable scale.

Top Autumn Crops for Your Greenhouse

1. Leafy greens:
   • Spinach: Fast-growing and frost-tolerant, spinach performs well in cooler autumn conditions. Sow the seeds directly into the soil and keep the soil evenly moist.
   • Lettuce: Varieties such as butterhead and romaine lettuce grow well in milder weather. Successive sowings provide a steady supply.
   • Kale: Hardy and nutritious, kale tolerates cooler temperatures and makes a versatile addition to autumn meals.
2. Root vegetables:
   • Carrots: Ideal for autumn planting, carrots prefer loose, free-draining soil. Thin seedlings so the roots have sufficient room to develop.
   • Radishes: Quick to grow, radishes suit successive sowing. They thrive in compact spaces and containers.
   • Beetroot: Another excellent choice, beetroot can be harvested for both its roots and its leaves.
3. Brassicas:
   • Broccoli: Prefers cooler weather and can crop well in greenhouses. Allow enough space for plants to develop fully.
   • Cauliflower: Needs a little more attention but rewards you with delicious heads. Monitor humidity to help prevent mould.
   • Cabbage: Plant in well-drained soil and protect against pests. Autumn varieties can be especially sweet and tender.
4. Herbs:
   • Parsley: Hardy and versatile, parsley can be picked throughout autumn. Keep the soil moist and provide plenty of light.
   • Coriander: Thrives in cooler conditions and adds fresh flavour to seasonal dishes. Pick leaves regularly to encourage growth.
   • Chives: Easy to grow and ideal for adding a mild onion flavour to meals. Chives can be harvested continuously.
5. Other crops:
   • Swedes: Both roots and leaves are edible, making turnips a valuable crop. Plant them in rich, well-drained soil.
   • Swiss chard: Colourful and nutritious, Swiss chard handles cool weather and can be harvested several times.
   • Peas: Sugar snap and garden peas grow well in cooler weather. Provide support for climbing varieties.

Tips for Successful Autumn Greenhouse Growing

1. Temperature control: Monitor conditions and maintain suitable temperatures with ventilation and, where needed, heating. Good insulation helps retain warmth on cool nights.
2. Light management: Supplement natural daylight with grow lights where necessary, especially as days shorten. Position lights so crops receive even illumination.
3. Watering: Plants need less water in cooler weather, but consistent moisture remains important. Avoid overwatering to reduce the risk of root rot.
4. Soil preparation: Enrich soil with compost and organic matter to improve nutrients. Ensure good drainage so water does not collect around roots.
5. Pest and disease management: Inspect plants regularly for pests and disease. Check that any biological treatment is currently authorised in Malta and follow its crop-specific label; good airflow also helps minimise problems.
