North Ayrshire Growing Conditions
Soil, hardiness and a planting calendar for North Ayrshire — across 11 postcode districts.
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 very wet climate (1467mm a year) — drainage is the priority, moisture-loving planting thrives, and paving and lawns must be laid to drain. A long growing season (~351 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 North Ayrshire
