The Climate for Growing Braeburn Apples

Winter Climate

• Temperatures rarely fall below freezing in the Braeburn apple's native New Zealand. The trees flower and produce fruit right on schedule when grown in these mild climates, which provide cool winter temperatures but minimal frost and only short periods when temperatures remain below freezing. Braeburns also grow in colder areas that experience prolonged periods of freezing, but they may flower and fruit later.This apple tree is not typically grown as an early-producing apple tree in cold climates.

Spring Frost Concerns

• Braeburn apples may not produce as well in climates prone to late spring frost, especially after a period of above-freezing weather. A late frost that occurs during flowering can kill the flowers before they have a chance to become pollinated and set fruit. Planting on higher ground keeps the tree out of the low-lying pockets of cold air that often occur in colder climates during the late spring months. The slower fruit development caused by cooler spring climates may also result in a calcium deficiency, which is remedied with a calcium spray during the early days of fruit formation.

Sun and Moisture

• All apple varieties, including Braeburn, require full sunlight during the spring and summer months to grow and produce well. Braeburns may not reach their full potential in climates prone to extended periods of overcast weather. The trees also require consistently moist soil. Grow apple trees in dry climates successfully by supplying supplemental irrigation and providing mulch over the root zone of the tree. The trees need approximately 1 inch of water per week during the spring and summer season, either via irrigation or natural rainfall.

Summer Fruit Production

• Fruits typically reach maturity in midsummer when Braeburns are grown in their preferred mild climate. In colder climates, fruit maturity is often delayed until late summer due to the slower development during the cooler spring and early summer months. This slower fruit development can also result in ripened apples that don't develop their full sweet flavor. In hot climates, the trees require more frequent irrigation to adequately support the leaves and fruits, because moisture evaporates from the soil more rapidly.
