Maine Coastal and Northern Vegetable Garden

A UMaine planting-window guide for central Maine dates, coastal and northern timing shifts, spring greens, warm transplants, and fall rows.

Climate signals

• UMaine Extension's planting chart gives central Maine vegetable planting windows and says the two listed dates are the earliest and latest safe dates.
• For coastal Maine, UMaine says to plant 10-14 days earlier than the central Maine dates.
• For northern Maine, UMaine says to plant 10-14 days later than the central Maine dates.

Planning notes

• Use spinach as a two-season row in central Maine, with 4/10-5/10 and 7/1-8/1 planting windows before local adjustment.
• Use peas 4/15-7/15, beets 4/25-8/1, and carrots 5/1-7/15 for long cool-season direct-sow planning.
• Use broccoli, cabbage, and turnips in the 5/1-8/1 central Maine planting window where local timing applies.
• Hold snap beans to 5/15-7/15 and corn to 5/15-7/1 before applying the coastal or northern adjustment.
• Plan tomatoes and peppers for 5/25-6/20, eggplant for 6/1-6/15, cucumbers for 6/1-7/15, and winter squash and pumpkin for 5/20-6/10.
