The best time to plant potatoes in Connecticut is typically about 2 to 3 weeks before the average last frost date, which usually falls around mid-May in many parts of the state. This means planting potatoes in late March to early April is ideal, as long as the soil has dried enough to be workable and is not overly cold or waterlogged. For example, in Hartford, CT, the last frost date averages around May 12, so planting between late March and early April would be recommended. In specific locations within Connecticut, planting potatoes around mid-March is also suggested if the ground is not frozen. Potatoes should be planted in soil that has a temperature around 45-50°F and is free of weeds and clumps, in rows about 24-36 inches apart at a depth of 3-4 inches. Summary points:

• Plant potatoes about 2-3 weeks before the average last frost date (mid-May in many CT zones).
• This corresponds to late March to early April planting time.
• Soil should be workable (not frozen or too wet).
• In Hartford area, last frost date is May 12; plant potatoes by late March to early April.
• Soil temperature of about 45-50°F is ideal for planting seed potatoes.

This timing helps potatoes emerge quickly and grow steadily without frost damage, ensuring a good harvest later in the summer or early fall in Connecticut.
