Gardening in Devon
Devon offers a varied gardening picture: mild, moist coastal districts contrast with cooler Dartmoor-edge and north Devon sites. The county's generally wet, green character supports lush growth, but wind, shade and waterlogged soil can delay spring work. South-facing sheltered gardens often enjoy a generous season, whereas upland or valley-bottom plots require more patience after winter and protection for early seedlings.
The growing season in Devon
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 Devon
Potatoes, peas, beans, leafy crops, currants and soft fruit generally appreciate Devon's moisture-retentive conditions, provided drainage is sound. On heavier clay or damp ground, raise beds and add well-rotted organic matter to improve structure. Coastal gardeners can grow a wider range of tender plants behind shelter, while upland growers should favour reliable hardy vegetables, fleece young plants during cold snaps and avoid planting into cold, saturated soil.
