Jobs To Be Getting On With
You may find this month that you will need to introduce heat into your greenhouse as the outside temperature starts to drop. As a good rule of thumb, you should aim to maintain a minimum night-time temperature of 5 – 7°C (42 – 45°F) if you intend to keep your greenhouse frost-free. If frost is forecast, you may need to protect tender plants with a horticultural fleece or newspaper.
As winter approaches, make sure that all half-hardy plants have been brought into the greenhouse. In colder parts of the UK you may wish to insulate your greenhouse using bubble wrap. Find out what else you can be sowing and planting in October with our downloadable Growing Guide for October.
