The soil temperature is generally warm enough for heat-loving crops by late May and early June. This is when you should consider planting tomatoes, peppers, and cucumbers. Corn is another vegetable that thrives when planted in late spring or early summer. These plants require a longer, warmer growing season, so planting them too early or too late could result in poor yields.

Fall Vegetable Planting Tips for Eastern North Dakota

In Eastern North Dakota, fall planting generally starts in late July to early August for cool-season vegetables. Vegetables like kale, lettuce, and radishes thrive in cooler temperatures and can be harvested until the first hard frost. In Eastern North Dakota, fall is also an excellent time for planting garlic, which will grow over winter and be ready for harvest the next summer. 

Cover crops like rye can also be planted to protect and enrich the soil throughout winter. Monitoring the weather forecasts closely is crucial, as an early frost can damage or kill off your fall crops. Gardeners can use cold frames or frost blankets to make their growing season last longer into the late fall.

Ideal Fall Planting Dates for Western North Dakota

Western North Dakota’s drier and cooler climate calls for different strategies for fall planting. Consider planting your fall vegetables in mid to late July in this region. This will give your crops enough time to mature before the colder temperatures hit. Like the Eastern region, cool-season vegetables like cabbage, beets, and turnips are good choices for fall planting.

Utilizing indoor growing methods can keep you gardening year-round and give you a head start on the next outdoor growing season.
