Method Start from local dates Use the dates for Ercolano 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.
Sources and limits Use these dates as practical guidance, not fixed deadlines. Exposure, soil, containers, irrigation, and the next few days' forecast can move the right timing earlier or later.
