When Should I Prune Elm Trees

Dutch Elm Disease, or DED, is a fungus affecting all types of Alberta Elm trees. It is imperative to follow specific pruning guidelines to avoid catching or spreading this deadly disease. In April-September, you want to refrain from trimming, as this is when DED-spreading beetles can be at their worst. Before April or after September, you should remove any unhealthy or dead portions of your Elm, which will help remove the breeding grounds for infected beetles. However, suppose you see any yellow or wilted leaves near the top of your Elm Tree, regardless of the time of year. In that case, you should remove those branches immediately, as they most likely suffer from DED.

When Should I Prune Apple Trees

While many trees have specific seasons best for pruning, your Apple Tree can benefit at different times of the year. If you choose to prune your Apple Tree during the summer, this can help it produce more fruit! Trimming it back will encourage its growth and result in more apples, but be sure only to do a light trim, as over-pruning can be harmful. Once the growing season is over, it can also be an excellent time for a clean-up. It will prevent weak or dying branches from breaking over the winter months and can help strengthen your tree for a great growing season next year. It is important to trim back any small or weak branches that won’t be strong enough to hold the weight of the apples and cause breakage. Winter is an excellent time for any more significant pruning as it will cause minimal stress to your Apple Tree.

When Should I Prune Birch Trees

When it comes to Birch Trees, it is best to prune them in the summer or early fall. Avoid trimming them all together when they are coming out of their dormant season, as they will have a heavy sap flow during this time. Your Birch Tree can grow quite large, so it’s essential to keep it trimmed to avoid any hazardous branches from falling.
