A severe thunderstorm warning has been issued for eastern Johnson, northwestern Nemaha and southern Otoe counties in Nebraska until 3:15 p.m. Sunday. A tornado watch is in effect until 10 p.m. Sunday for southeast Nebraska and southwest Iowa, including Omaha, Council Bluffs and Lincoln.
Now that fall has arrived and cooler temperatures are becoming the norm, it's time for Nebraska gardeners to determine what to harvest and when.
Some crops will need to be harvested before a frost while others can withstand colder temperatures.
Warm weather loving crops that do not tolerate frost and low temperatures include tomatoes, peppers, sweet potatoes, okra, eggplant, cucumbers and summer squash. Watermelon, cantaloupe, pumpkin, corn and eggplant also are sensitive to cool temperatures and can result in plant damage or death.
Crops that withstand a light frost between down to 30 degrees include beets, mustard, Chinese cabbage, radishes, collards, spinach, potatoes, Swiss chard, Bibb lettuce, green onions and leaf lettuce.
Crops that can withstand several freezes include cabbage, carrots, broccoli, cauliflower, rutabagas, Brussels sprouts and kale.
