Nebraska Planting Zone – USDA Map Of Nebraska Growing Zones
The USDA map of Nebraska growing zones (5b) was released in March 2014. It shows the different types of plant life in each type of zone. A few facts about 5b:
It’s a semi-arid region with little rainfall. Soil moisture levels are low, so most plants prefer dry soil conditions.
Plants grow best in areas where temperatures range from 50°F to 75°F. They do better if they get nighttime temperatures between 65°F and 80°F.
Zone 5a is a wetter area with average night temperature around 70°F. Plants like moist soil conditions, but don’t thrive there as well because of high afternoon dew point temperatures.
Zone 6 is a desert area with temperatures ranging from 100°F to 120°F. Most plants need cool nights, so daytime temperatures must stay above 85°F.
Plant growth rates will decrease when night temperatures drop below 55°F or rise above 95°F. Cold nights slow down plant growth, while hot days speed it up. This means that plants grown in cold weather have to be moved into warmer climates at least once every two years to keep them alive.
Plants grown in hot weather will need to be moved to a cooler environment. They should be grown in the spring and fall, when days are cooler.
Zone 7 is a wetter area with average rainfall between 15 and 20 inches of rain per year. It’s best for growing plants that grow in the wild or like 5a. It can support plants that like both conditions, but they don’t do as well there as they do in zone 5a.
