Gardening in County Durham
County Durham offers gardeners sheltered lowland sites around towns and river valleys, alongside cooler, exposed Pennine ground to the west. Spring can be slow on higher plots, while urban gardens may gain a little useful warmth. Rain, wind and occasional waterlogged soil are familiar constraints, but fertile valley soils can be very productive. The season favours gardeners who protect young plants and make the most of every sheltered corner.
The growing season in County Durham
Based on the North of England region: last spring frost late May to early June, first autumn frost late September to October.
Growing seasons are generally cooler and shorter than farther south, particularly away from sheltered coasts and in the Pennines. Long summer daylight can still favour many crops, but late spring frost and an early autumn chill constrain tender plants. These are broad averages: altitude, exposure, valleys and urban shelter can make neighbouring gardens markedly different.
What grows well in County Durham
Hardy crops including leeks, peas, broad beans, cabbage-family vegetables and potatoes are sound foundations in County Durham. In western or elevated gardens, start tender vegetables under cover and plant out only when conditions have settled; a greenhouse extends the choice of tomatoes and peppers. Improve clay or compacted soil with organic matter and avoid working it when wet. Gooseberries, blackcurrants and raspberries usually suit the cooler conditions, provided canes have some wind shelter.
