Mid Devon Growing Conditions
Soil, hardiness and a planting calendar for Mid Devon — across 7 postcode districts.
Soil
The soil most gardeners wish for: a free-draining, slightly acid loam that warms early in spring and rarely waterlogs. It suits the widest range of planting — vegetables, perennials, shrubs and trees — and asks little beyond an annual mulch to keep its structure. Because it drains freely it can dry in a hot summer, so new plants, pots and lawns benefit from steady watering through July and August. For patios, paths and walls its stability makes for straightforward foundations.
Winter hardiness
Rated RHS H4 — the UK mainstream, with winter lows near -6°C. The vast majority of garden plants, perennials, shrubs and trees come through a normal winter unprotected; only genuinely tender exotics need a warm corner or cover.
Rain & growing season
A wet climate (1106mm a year): plants rarely go thirsty, but lean on good drainage, disease-resistant varieties and falls that shed water off paving and lawns. A long growing season (~352 frost-free days) — you can sow earlier and harvest later than most of the country, and squeeze in a second late sowing.
Planting Calendar for Mid Devon
The long season allows a second sowing of quick crops in July.
