Vale of Glamorgan Growing Conditions
Soil, hardiness and a planting calendar for Vale of Glamorgan — across 5 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 -5°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 wet climate (1083mm 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 (~356 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 Vale of Glamorgan
The long season allows a second sowing of quick crops in July.
Timings are guided by this area's ~356 frost-free days and RHS H4 hardiness; adjust for a cold or sheltered garden.
