London planting calendar
London is zone 9 with mild winters and a long, cool growing season; the last frost is usually in April and the first in November. The limit is light and wet soil rather than cold, so autumn planting and raised beds pay off.

How to use it. Start with the frost line, not the month name. If your last frost is earlier or later than the one above, shift the spring rows by the same number of weeks. Soil temperature matters more than the date for warm-season crops.
What this calendar assumes
- An open, sunny bed with drainage; shade and wet soil shift every row.
- Typical frost dates for the zone or city, not a specific garden's microclimate.
- Seed and transplant dates for a home garden, not commercial scheduling.
- No heated greenhouse; a polytunnel or conservatory buys two to four weeks at each end.
