As winter approaches, gardeners face the challenge of maintaining a warm greenhouse. To help you keep your plants thriving, here are some top tips on how to keep your greenhouse warm in winter:
- Consider adding bubble wrap insulation to your greenhouse walls for an extra layer of warmth.
- Use thermal mass objects such as water barrels or concrete blocks to retain heat.
- Make sure to seal any gaps or cracks to prevent cold drafts from entering.
- Invest in a greenhouse heater, preferably one with a thermostat, to maintain optimal temperatures.
- Use horticultural fleece to cover plants during extremely cold nights for additional protection.
