Tips for gardeners growing indoors

Author and polytunnel gardening expert, Klaus Leitenberger extols the benefits of growing under cover and gives good reasons why avid food gardeners should consider investing in a polytunnel for year-round crops. 

I have always been passionate about growing food — all kinds of it and I never liked buying food that can be grown in my own garden. Unfortunately in our climate there is a whole range of common vegetables that will do poorly outdoors and we need the extra heat and shelter of a greenhouse or polytunnel to get a good crop.

Only in the most favourable areas could you grow tomatoes, peppers and cucumbers outdoors and even there, the yield will only be a fraction of what can be achieved indoors.
