Last year's fruited canes should be removed now if they were not removed last summer or fall. Remove weak or spindly floricanes and thin to 2-4 canes per foot of row. If the planting is trellised, the canes should be tied to the wires now before growth starts. Fall bearing types should be mowed to the ground before growth begins for a fall-only harvest, or remove the fruited tips if a summer and fall harvest is desired. Remove and destroy the prunings to help prevent anthracnose.
Spring is the best time to prune blueberries.
Winter injured wood is easily identified and should be removed. Try to establish an even number of canes of various age classes. Pruning should open the center of the bush to encourage new cane growth, and promote an upright growth habit by removing low, drooping branches. Detailed pruning to remove weak growth in the tops of the canes will reduce the number of fruit and improve fruit size. The most important spray you will apply this season for control of anthracnose on brambles is the delayed dormant spray of lime sulfur.
