Q. When should you prune trees?
A. Generally speaking, the only constant rule when talking about the 'when' of pruning is never ever EVER prune in the fall. Pathogens causing diseases like heart rot are more active during that time so making cuts on your tree opens them up to possible infection until they can heal over. There are different times for pruning to encourage flowering, new growth, thickening or thinning the canopy, so the best thing to do is follow the best practice for what your hoping to accomplish with pruning. We don't have an in depth article on the in's and out's of tree pruning yet but there are other resources on the web available. Please don't try to take large branches down yourself. Hire an arborist or landscape professional you trust and make sure to ask if they employ the 3 cut method. This is the best way to ensure you continue to have healthy trees after pruning.
Q. How much carbon dioxide does one tree remove from the air?
A. One mature tree absorbs approximately 13 pounds of carbon dioxide a year. For every ton of wood a forest grows, it removes 1.47 tons of carbon dioxide and replaces it with 1.07 tons of oxygen.
