Areas of full sun are best for blueberry production. Known as a woody perennial , blueberries are in the field year round though the growing season is mid-May through August. Though all growers hope for a good season, sometimes Mother Nature has other plans. Sometimes the weather is too cold, too rainy or too dry. Growers have to plan in advance for this and take precautions.
Blueberries run the biggest risk of experiencing very cold weather and frosts.
Blueberry growers use irrigation for frost protection. When the weather reaches between 34 and 36 degrees Fahrenheit, irrigation begins. Water is released, spraying the plants and covering them. This water changes to ice. When water changes from a liquid to a solid like this, heat is released.
