Garden calendar for Trento: what to sow and transplant month by month Local vegetable-garden calendar for Trento.
Editions EN English IT Italian Garden calendar for Trento For Trento, this calendar shows when to sow, transplant, and protect the garden, based on local frost, heat, dry spells, and crop windows.
How to read the year In Trento, the garden year is best read from the cautious last-frost date: after May 26, windows become more suitable for sensitive crops.
The strongest part of the calendar falls in May, June, July: these are the months with the most recommended direct-sowing and transplant windows.
Toward autumn, the cautious first frost is around September 14. The main year-level check is: cold risk for sensitive sowing, dry-spell risk: plan irrigation.

Method Start from local dates Use the dates for Trento 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.
