Raintree offers special low chill apple varieties for Southern growers who don't get enough chill hours to grow most apples. Fruit trees require a certain number of chill hours to fruit. Chill hours are those hours between 32F and 49F.
In the North, growers generally get enough chill hours. However, many Southern growers may get from zero to only 600 hours depending on location and year. See our chill hour chart for the approximate hours in your area.
