Maidstone Growing Conditions

Soil, hardiness and a planting calendar for Maidstone — across 9 postcode districts.

RHS H3 free-draining, fertile near-neutral loam 708mm rain

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

A mild area rated RHS H3 — winters usually bottom out around -4°C. Most hardy plants are safe, and you can grow half-hardy exotics that fail further north, but the occasional hard frost means tender plants still want a sheltered wall or winter fleece.

Rain & growing season

One of the drier parts of the country (708mm a year), so established beds still need summer watering and drought-tolerant planting pays off. A long growing season (~348 frost-free days) — you can sow earlier and harvest later than most of the country, and squeeze in a second late sowing.
