Blueberries, favorites in pies, jams and juices, are fairly easy to grow. While blueberry bushes require specific climate and soil conditions to maximize their production, gardeners can ease back on their care during the winter months.
Mulch your blueberries in late fall, at least two weeks before the first frost date. Adding mulch will give the bushes winter protection, but more importantly it will preserve moisture. Good choices for mulch include pine needles or leaf compost. If you use wood chips or sawdust, make sure they are partly decomposed so they do not remove nitrogen from the soil.
Water after early September only if the soil is extremely dry or if you are in drought conditions.
Prune your bushes in mid-March only if they are at least 4 years old. Blueberry bushes do not need to be pruned during their first three years. When you prune, remove dead and weak branches. Also remove any interior crossing branches.
