Cherwell Growing Conditions
Soil, hardiness and a planting calendar for Cherwell — across 10 postcode districts.
Soil
A free-draining, fertile soil close to neutral — one of the easier soils to garden. It suits a very wide range of planting, from vegetables to fruit and ornamentals, and works readily in most seasons. Keep it fed and mulched; being free-draining, it can dry in high summer. A firm, stable base for hardscaping.
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
One of the drier parts of the country (745mm a year), so established beds still need summer watering and drought-tolerant planting pays off. A typical UK growing season (~325 frost-free days), with the last frosts clearing through spring and first frosts returning in autumn.
Planting Calendar for Cherwell
Timings are guided by this area's ~325 frost-free days and RHS H4 hardiness; adjust for a cold or sheltered garden.
