When to plant garlic in San Sebastián: 1 October – end of December

In San Sebastián, garlic: plant from 1 October to the end of December. In Spain garlic is planted from October in every region (Spain’s agriculture ministry, MAPA, Hojas Divulgadoras 1/84); we give October to December. For planting stock, the places nearby include Loraldi (garden centre, 6 km) and Endanea Garden Center (garden centre, 13 km); addresses and opening hours are below.

Garlic is best planted early in the window: cloves planted late make smaller bulbs. Late planting works only while the soil is not frozen. Mulch after planting.

The average daily temperature here stays above 0 °C all winter, and at least two months average 10 °C or less: the cold garlic needs, one to two months at 0–10 °C (RHS). The two-month threshold is our rule of thumb. Sources: UVM Extension, UNH Extension, RHS.
