Neath Port Talbot Growing Conditions
Soil, hardiness and a planting calendar for Neath Port Talbot — across 7 postcode districts.
Soil
A shallow, free-draining acid loam over hard rock. It warms fast and rarely waterlogs, but dries quickly and offers limited rooting depth — ideal for drought-tolerant and acid-loving planting, with mulch to conserve moisture. Rock near the surface can complicate deep footings and tree planting.
Winter hardiness
Rated RHS H4 — the UK mainstream, with winter lows near -7°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 (1303mm a year) — drainage is the priority, moisture-loving planting thrives, and paving and lawns must be laid to drain. A typical UK growing season (~339 frost-free days), with the last frosts clearing through spring and first frosts returning in autumn.
