The safest way to start strong is to know your local last-frost <strong>window<\/strong>, then plant on a timetable that respects your microclimate and your crop\u2019s <strong>tolerance<\/strong>. \u201cPlanting a week late never ruined a <strong>harvest<\/strong>, but planting a week early often <strong>has<\/strong>,\u201d as one allotment keeper in Galway likes to <strong>say<\/strong>.<\/p>\n<p><\/p>\n<p>Frost risk in Ireland is shaped by <strong>latitude<\/strong>, the softening Atlantic, and the shelter or exposure of nearby <strong>hills<\/strong>. Coastal sites are often frost-free <strong>earlier<\/strong>, while inland basins and higher ground hang on to cold a bit <strong>longer<\/strong>.
