According to the Northwest Berry and Grape Information Network, taking the proper cutting is the key to successful propagation. A cutting, also known as a whip, is most likely to take root if cut during the dormant season. Experienced growers recommend using one-year-old whips no wider than a pencil.
In addition to choosing healthy whips, blueberry growers are more likely to be successful with some preparation. Removing buds and berries helps prevent rot. Whips grow best in propagation when placed in a sunny location.
Cuttings planted in 2 inch by 2 inch groupings are most likely to develop roots and produce mature plants. Blueberries thrive with weekly watering and moist, well drained soil.
