Planning a Michigan garden around these dates
Count back from the last spring frost to schedule indoor seed starting (the seed starting scheduler automates it), plant hardy crops in the weeks before the date, and hold tender crops — tomatoes, peppers, squash, basil — until after it. In fall, the first frost date is the deadline: crops must mature before it, which is what our planting calendar counts backwards for you. Crop-by-crop timing for every USDA zone lives under when to plant.
