Boston Growing Conditions
Soil, hardiness and a planting calendar for Boston — across 5 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
A mild area rated RHS H3 — winters usually bottom out around -5°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 (734mm a year), so established beds still need summer watering and drought-tolerant planting pays off. A long growing season (~341 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 Boston
The long season allows a second sowing of quick crops in July.
Timings are guided by this area's ~341 frost-free days and RHS H3 hardiness; adjust for a cold or sheltered garden.
