Cool-season crops
These hardy greens and legumes thrive in cold soil and mild temps, often outperforming when planted early or late.
Sow directly as soon as the ground can be worked in early spring, even if snow lingers or nighttime temps hover near freezing. Many cool-season crops germinate well down to 40°F soil temperature, with spinach and peas performing best below 75°F. Avoid planting during warm spells—high temps trigger premature bolting in leafy greens and poor pod set in peas.
Plan for two growing windows: one in early spring before trees leaf out (when shade and cooler temps protect tender seedlings) and a second in late summer for a fall harvest. succession planting helps, but spacing matters—thinning too late stresses plants and invites disease. Mulch with straw or shredded leaves to moderate soil temp swings and prolong harvest.
Watch for pest pressure that peaks in cooler months, like cutworms on young kale or aphids on peas. Use floating row covers early to prevent infestation without chemicals. Harvest outer leaves first on greens like spinach and kale to encourage continued growth, and cut entire pea vines only after most pods mature to avoid weakening the plant.
