So, I thought an appropriate post today would be about proper and safe tree trimming.
- MAPLES - Maples trimmed at certain times of the year will "bleed" or drip from the pruning cuts. Bleeding is most likely to occur when Maples are pruned in the seasons just before and right after winter. Studies indicate that "bleeding" doesn't hurt the tree, so it becomes more of a cosmetic issue. If you want to prune Maples without bleeding, it must be pruned when it is fully dormant in the middle of winter (Jan or Feb) or during late spring (June) or summer (July, Aug, Sept) when it's in full leaf.
- DOGWOODS - If you trim Dogwoods in April or May, it will make them more susceptible to the dogwood borer. This insect severely damages the vascular system of the tree after boring into the trunk.
- OAKS - Oaks should be not be trimmed from April thru October, due to the prevalence of Oak Wilt disease pathogens during that time frame.
