Growing Garlic in Nova Scotia: Planting Dates, Varieties and Winter Cold
Nova Scotia has enough winter cold for garlic vernalization, and cloves go in a few weeks ahead of Halifax’s average October frost date.
Home & garden, state by state
Everything we have worked out for Nova Scotia: what to plant and when, which varieties finish in time, the pests that actually turn up here, and the jobs that pay off month by month. We also cover the rest of the property, from lawns and soil to home care and energy, because a garden rarely stops at the vegetable bed.
The numbers first, because everything else follows from them. Measured at the weather station in Halifax, the last spring freeze falls around May 7 and the first fall freeze falls around October 18, 1,659 growing degree days in the year.
That is enough for early varieties, tight for anything late. Garlic does well: 30.4 weeks below 40 °F, comfortably past the six it needs to form a proper head.

Nova Scotia’s average frost dates and 163-day frost-free season, from Halifax Stanfield climate data, set the planting window and variety choice for home tomato growers.
Halifax Stanfield’s average last frost falls May 7, but count backward from late May transplanting and forward to the October 18 fall frost to pick a safe date.
Nova Scotia’s frost-free season runs about five months on average; this guide lists the tomato varieties, from 55-day cherries to 78-day slicers, that ripen inside it.
