Method and limits
Start from local dates
Use the dates for Trieste as practical guidance, then adjust for exposure, elevation, and shelter in your garden.
Check cold, heat, and dry spells
Before sowing or transplanting, check frost, cold nights, heat waves, and periods without rain.
Respect crop needs
Each crop needs warm enough soil, frost protection, and a different amount of time to reach harvest.
Choose the safest window
Use recommended windows as the main reference; move earlier or later only when weather and microclimate help.
