Method and limits

  1. Start from local dates

    Use the dates for Bolzano as practical guidance, then adjust for exposure, elevation, and shelter in your garden.

  2. Check cold, heat, and dry spells

    Before sowing or transplanting, check frost, cold nights, heat waves, and periods without rain.

  3. Respect crop needs

    Each crop needs warm enough soil, frost protection, and a different amount of time to reach harvest.

  4. Choose the safest window

    Use recommended windows as the main reference; move earlier or later only when weather and microclimate help.
