Build a Monthly Planting Calendar for My Climate Zone

Knowing what to sow is half of it; knowing when is the half that catches people out. Give your climate zone and the crops you want, and this builds a month-by-month calendar: what to sow indoors, what to sow direct, what to transplant and what to harvest, with frost dates, hardening-off windows and succession sowing flagged. The year laid out so nothing gets missed.

Create a month-by-month planting calendar for a gardener in {climate_zone} (e.g. UK South-East, USDA zone 7, temperate maritime). I want to grow a mix of {crop_types} (e.g. salad leaves, root vegetables, brassicas, herbs). For each month list: what to sow indoors, what to sow direct outdoors, what to transplant, and what to harvest. Note any key frost dates, hardening-off windows, or succession sowing tips. Format the output as a clean 12-row table with columns for each task type. Add a short paragraph at the end flagging the three most time-critical windows in the year where missing the window means waiting another full season.
