Garden Pests in Prince Edward Island: What Shows Up, When, and How to Stop It
Prince Edward Island’s cool maritime climate and heavy potato and vegetable farming create a specific pest calendar: slugs and cutworms hit in spring…
Home & garden, state by state
Everything we have worked out for Prince Edward Island: 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 Charlottetown, the last spring freeze falls around May 16 and the first fall freeze falls around October 17, 1,569 growing degree days in the year.
That is enough for early varieties, tight for anything late. Garlic does well: 34.8 weeks below 40 °F, comfortably past the six it needs to form a proper head.

Figures from Environment and Climate Change Canada. A state is not one climate: elevation, a large lake or the coast can move these dates by two weeks either way, so check your own county with the extension service before you spend money.
