As the seasons change, it’s important to know when to transition your kitchen garden plants into a greenhouse. This move can help protect your plants from harsh weather conditions and extend your growing season. Here’s a guide to help you determine the best time to move your plants and ensure they thrive in their new environment.
1. Understanding the Right Time
Seasonal Changes: The most common time to consider moving plants into a greenhouse is during the transition from autumn to winter. As temperatures drop, many plants struggle to survive the cold. A greenhouse provides a controlled environment that can keep them warm and protected.
Frost Warning: Keep an eye on local weather forecasts for frost warnings. Frost can damage or kill many kitchen garden plants, especially tender herbs and vegetables. When frost is imminent, it’s time to move your plants into the greenhouse.
Day Length: Shorter days and reduced sunlight can affect plant growth. Moving plants into a greenhouse with supplemental lighting can help maintain their growth cycle and productivity.
2. Preparing Your Greenhouse
Cleaning and Maintenance: Before moving your plants, ensure your greenhouse is clean and in good repair. Remove any debris, wash the windows to maximise light, and check for any repairs that need to be made.
Temperature Control: Equip your greenhouse with a reliable thermometer and heating system. Maintain an optimal temperature for your specific plants, generally between 15°C and 25°C, depending on their needs.
Ventilation: Proper ventilation is crucial to prevent mould, mildew, and pests. Ensure your greenhouse has adequate ventilation, such as windows or vents that can be opened during warmer days.
3. Selecting the Right Plants to Move
Tender Plants: Plants that are particularly sensitive to cold, such as basil, tomatoes, and peppers, should be prioritised for the move. These plants will benefit significantly from the warmth and protection of a greenhouse.
Perennials and Herbs: Herbs like rosemary, thyme, and mint, as well as perennial vegetables like asparagus, can continue to grow in a greenhouse environment. Moving them indoors can extend their productivity through the colder months.
Young Seedlings: If you’re starting new seedlings for the next growing season, a greenhouse provides an ideal environment for germination and early growth. Moving young plants into the greenhouse ensures they get a strong start.
4. Transitioning Your Plants
Gradual Acclimatisation: To prevent shock, gradually acclimate your plants to the greenhouse environment. Start by placing them in the greenhouse for a few hours a day, gradually increasing the time they spend indoors over a week.
Monitor Watering Needs: Plants in a greenhouse may require different watering schedules than those outdoors. Check soil moisture regularly and adjust your watering routine to prevent overwatering or underwatering.
Pest Management: Inspect your plants for pests before moving them into the greenhouse. Greenhouses can provide a perfect environment for pests if they are not managed. Use natural pest control methods and keep a close watch for any signs of infestation.
5. Ongoing Care
Regular Monitoring: Check your plants daily for any signs of stress, disease, or pests. Maintaining a consistent environment and addressing issues promptly will help your plants thrive.
Pruning and Maintenance: Continue to prune and care for your plants as needed. Removing dead or damaged leaves and ensuring good air circulation will keep your plants healthy.
Feeding: Plants in a greenhouse may need regular feeding due to the controlled environment. Use organic fertilisers to provide the necessary nutrients and support growth.
By following these guidelines, you can successfully transition your kitchen garden plants into a greenhouse and continue to enjoy fresh produce and herbs throughout the colder months. A well-maintained greenhouse can be a haven for your plants, ensuring they remain healthy and productive year-round.
