How to Plan a Fall Vegetable Garden

Practical takeaway

Fall planning works backward. Start with a local first fall freeze probability date, subtract the crop’s maturity range, then add time for establishment and slower growth as light declines.

The planting calendar uses reviewed frost-relative offsets for supported crops. It does not simply subtract packet days from one freeze date. Broccoli, cabbage, kale, lettuce, spinach, carrots, radishes, and cilantro each need different lead time.

Managing summer establishment

Many fall crops are started while the garden is still hot. Protect moisture, use temporary shade where appropriate, and select varieties intended for the season. A cool-season label does not make seed germinate well in hot soil.

Limits

The first freeze may not end a cold-tolerant crop, while low light may slow it before then. Protection, cultivar, latitude, and winter severity affect the real endpoint.
