Greenhouses help us produce more food for a longer time - we know this already! But what if we went the extra step and took our greenhouse to the next level? Greenhouses alone can extend the growing season by months - without any extra heating.
Greenhouse gardening is the best way to undertake winter gardening because it allows you to enjoy your hobby when it's freezing cold outside. Of course, if you want to see success here, there are some things you will need to do. Keep reading to find out more.
The first thing to decide is how much of your greenhouse you want to keep warm and so need to insulate. Usually a greenhouse starts to fill when the weather is warming in spring and in the cold of winter it's probably just overwintering some tender perennials and getting an early start on some seedlings so not needing all the available space.
Things will grow very slowly if at all in December and January. Not so much because of the temperature but because the length of the day is at its shortest around the winter solstice (21st December). They will be gathering their energies ready to leap ahead come February when the days noticeably lengthen so long as the greenhouse is at least frost free.
