Gardening in Somerset
Somerset's gardening conditions shift from sheltered, relatively mild lowlands to exposed Mendip and Blackdown slopes, with the Levels bringing fertile but sometimes very wet ground. Winter water and local frost pockets shape the season as much as warmth does. Gardens on slopes often warm earlier than valley plots, while low-lying sites benefit from good airflow, drainage planning and a cautious approach to tender planting in spring.
The growing season in Somerset
Based on the South West England region: last spring frost late April to mid May, first autumn frost late October to November.
One of Britain's longest growing seasons, shaped by mild maritime conditions. Coastal Cornwall, Devon and sheltered urban gardens may stay largely frost-free for long spells, while inland valleys and higher ground can be notably colder. These are approximate regional averages only: aspect, altitude and frost pockets can make a garden behave very differently.
What grows well in Somerset
The county's productive soils can support excellent apples, currants, beans, brassicas, onions and potatoes. On the Levels and other damp ground, use raised beds or broad paths to keep soil workable and avoid compaction. Clay-rich gardens respond well to compost and autumn mulching. In colder pockets, delay tender crops such as courgettes and French beans, but make the most of dependable cool-season salads, leeks and kale.
