If you are a nursery or garden center, most likely your plants are are between the ages of 1-3 years and not in need of heavy pruning. However, there is still some pruning you can do to that will stimulate growth and ensure the health of your plant inventory. The best time of year to prune is late winter right before spring hits. Pruning should occur if there is ever dead on the blueberry plant, if there are any branches crossing each other, if there are small branches at the bottom to be removed or if there are branches growing into the middle of the blueberry plant. Pruning the branches near the bottom of the blueberry plant can be especially important for a nursery or garden center, this will allow for maximum top growth of the blueberry plant.
We will have a video on how to prune blueberry plants in containers soon.
