Potato Harvest Calendar

Planting: In cold winter regions, plant seed potatoes in spring as soon as the soil can be worked. For a summer crop where the soil temperature does not climb above 85°F (20°C), plant 2-3 weeks before the last frost. For a fall crop, plant in late spring. In mild-winter regions, plant in late winter—4 to 6 weeks before the last frost—for a summer crop. Plant in late summer for a winter-into-spring crop. Potatoes are tolerant of cool soil and late frost. Set seed potatoes 2-4” (

Harvest sweet potatoes as soon as they are big enough to eat—usually when the ends of the vines begin to turn yellow. Harvest sweet potatoes before the vines are touched by frost. Frost can damage the tubers below. When to Harvest Sweet Potatoes Most sweet potato varieties are ready to harvest 95 to 120 days after transplanting. But smaller tubers—called “baby bakers”—can be lifted sooner if they are big enough to eat. Lift a few tubers to make sure they are the right size bef

Fruits are ripening by mid-summer. Keep fruit trees and vines thoroughly watered; avoid letting plants dry out, especially newly planted fruits and fruits growing in containers.

Most soft fruits–strawberries, raspberries, blackberries, blueberries, and currants–are bearing or nearing maturity by early summer.

Here is a fruit-by-fruit growing guide for early summer: Support fruit trees. Support heavily laden branches with stout stakes that are deeply forked at the top. Summe
