Q: What would cause small, thin branches to grow vertically (literally straight up like fence pickets) on the larger lower limbs? I have only seen pictures of this happening. Thank you.


A: The thin vertical branches that you are seeing are called water sprouts. Water sprouts normally arise from latent buds located on or just beneath the bark. These latent buds can be activated by a number of events, such as overpruning, fertilizing, drought, or insect activity. Water sprouts can even grow as a result of a lightning strike or from additional sunlight due to the removal of a nearby tree. In any case, it would be a good idea to have your tree and immediate area inspected by a local competent arborist.
