South Ayrshire Growing Conditions
Soil, hardiness and a planting calendar for South Ayrshire — across 5 postcode districts.
Winter hardiness
A mild area rated RHS H3 — winters usually bottom out around -4°C. Most hardy plants are safe, and you can grow half-hardy exotics that fail further north, but the occasional hard frost means tender plants still want a sheltered wall or winter fleece.
Rain & growing season
A wet climate (1262mm 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 (~353 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 South Ayrshire
The long season allows a second sowing of quick crops in July.
Timings are guided by this area's ~353 frost-free days and RHS H3 hardiness; adjust for a cold or sheltered garden.
