What to Do in the Garden in May: Key Tasks
May is the turning point when frost risk fades, soil finally warms enough for tender crops, and the garden shifts from cool-season growth into full summer production. The month rewards gardeners who break the work into clear categories rather than tackling everything at once: getting warm-season vegetables in the ground at the right time, refreshing soil and beds for heavy growth ahead, setting up consistent watering, and scouting for pests before they take hold. This checklist walks through every priority task across USDA Zones 3–10, from transplanting tomatoes and direct sowing squash to pruning spring-blooming shrubs and dividing crowded perennials.
