If you’re like most Oregonians, springtime is when we typically start getting enticed to move our thinking back to the great outdoors. In the Portland Metro area our summers are so short that we want to make sure everything is ready for the occasions when the sun decides to break through, so that we can thoroughly enjoy the outdoor activities we love. For the majority of us in the Portland Metro area, the beautiful vegetation is one of the anchors that keeps us attracted to this region, and let’s face it, it just keeps on growing and therefore needs some regularly scheduled maintenance and tree care.
This time of the year is critical for pruning, trimming, and plant care. Before dormancy breaks and the trees begin to leaf out, pruning is optimal for most trees. Although there are a few exceptions due to various insect or disease problems in particular species of trees seem to have as a grouping. For most trees, this is a great time to create clearance, do some shaping, remove conflicting and diseased branches, or simply get some sunshine back into dark places.
Spring is also recommended for wrapping up any tree planting that may be considered. The reasoning for this is because trees are still dormant and there is a lot of rain yet to come; this will reduce the need for supplemental irrigation. This is a critical factor to consider when planting as it reduces the risk of transplant shock.
Trees and shrubs that are well cared for will be less likely to be overtaken by disease or damaged by structural defects. Diseases that should be evaluated in the spring include Shot Hole for Cherry trees, Anthracnose for Dogwood’s, Dutch Elm Disease for Elms, and Leaf Spot on Photinia and Hawthorne’s.
The Walnut tree is famous in Portland for causing seasonal allergies. These trees produce a significant amount of pollen in May and June. For those of us who have hay fever these months can be miserable. Another tree to be aware of this month is the Elm tree. Elm trees are prone to disease and can only be removed or pruned between the months of October and April due to Dutch Elm disease. It is important to have a Certified Arborist evaluate Elm trees to see if removal or pruning is necessary.
Signs of Dutch Elm disease include wilting and yellowing of the leaves. Individual branches are typically affected in the lower portion of the crown, and careful examination of such branches typically reveals a hole approximately half the diameter of a pencil on the top of such branches. If you notice these signs and are unable to get to affected branches for careful examination, do not wait; call your local Certified Arborists to schedule an inspection.
