Massachusetts Extension Planting Chart Vegetable Garden
A UMass Extension planting-chart guide for Massachusetts crop groups, frost risk, direct/transplant markers, succession, and regional timing shifts.
Climate signals
- UMass Extension's Vegetable Planting Chart is for Massachusetts gardeners planning when to sow seeds or set out seedlings.
- Cool-weather crops can be planted in late winter or early spring as soon as the soil dries out enough to be worked, and many can be succession-planted for fall harvest.
- Eastern and southern Massachusetts may have earlier planting times; western and northern Massachusetts may have later planting times.
- Warm-weather crops should be transplanted into the garden only after all danger of frost has passed.
Planning notes
- Use the chart legend: plant seeds directly into the garden, plant transplants or sets, or plant seeds or transplants where both are marked.
- Cool-weather catalog examples include arugula, beets, carrots, lettuce, peas, radishes, spinach, Swiss chard, and turnip.
- Cool-weather brassica, allium, and root examples include broccoli, Brussels sprouts, cabbage, cauliflower, celery, dill, kale, collards, kohlrabi, leeks, parsnip, and rutabaga.
- Plant intermediate crops after the cool-weather crops and before the warm-weather crops; chart examples include basil, beans, corn, cucumbers, melons, pumpkins, summer squash, and winter squash.
- Use warm-weather crops as the frost-sensitive transplant group: eggplant, peppers, and tomatoes.
