Get Some Insulation In Place ...

Before you follow Adrienne’s advice and build yourself a propagator, remember to insulate your greenhouse first! There’s no point putting heat into your greenhouse if you let it all escape again and lining your greenhouse with an insulating material only takes a little bit of time and effort but will help to keep any heat in your greenhouse (even without a heater a simple lining of the greenhouse walls can often keep plants frost free). And once the insulation is in place you’ll be able to leave it there until Spring next year ... really useful as we sow new seeds and delicate seedlings start to appear.
