North Somerset Growing Conditions
Soil, hardiness and a planting calendar for North Somerset — across 10 postcode districts.
Soil
A fertile coastal-flat soil with a high water table and, near the sea, some salt influence. Growth is strong in summer but winter-wet; choose salt- and wind-tolerant planting near the coast and raise beds for vegetables. Drainage, and salt-resistant materials, matter for any hardscaping.
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
Moderate rainfall (932mm a year) — enough for most gardens without heavy irrigation, though pots and new plantings need watering in summer. A long growing season (~344 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 Somerset
The long season allows a second sowing of quick crops in July.
Timings are guided by this area's ~344 frost-free days and RHS H4 hardiness; adjust for a cold or sheltered garden.
