Are you concerned about the health of your trees? If so, you’re far from alone. Trees are a critical part of our environment, providing shade and oxygen and helping to clean the air. But sometimes it’s hard to tell whether a tree is healthy or not. Here are four easy tips to evaluate trees just by inspecting a tree’s trunk! Happy evaluating! Tree Health Assessment Trees are often thought of as long-living, static beings, but they are actually quite dynamic and ever-changing. Start your tree health evaluation by looking for wounds on the trunk, discolored spots, and a well-developed root flare. If a tree is otherwise healthy, then there is a good likelihood that the tree’s ailments can be
reversed with a little TLC from you (and, of course, following these tips to evaluate trees). Trunk Tips to Evaluate Trees Trunk Flare Is the flare of the trunk’s base visible to you? If yes, that’s a sign the tree is in good health. If the flare is buried, however, this calls for attention. With help from an AirSpade, arborists can excavate excess soil to expose the flare and remove girdling roots. With the trunk flare now exposed, only spoke-wheellooking roots should be left behind. Trunk and trunk base branches Can you see branches that shoot out from further down the trunk than looks normal? While this exact assessment may be affected by the particular species in question, a full and shapely canopy is a good sign of a healthy tree. There may be a few outlying sprouts on the trunk, but only a few shouldn’t be cause for concern. However, if there is heavy spouting towards the lower end of the trunk or your tree is starting to look more like a shrub at its base, or if the branches are dying back at the tips and the canopy is thinning, this is possibly a case of a tree buried in too much soil or mulch. After consulting with an arborist first to confirm, use an AirSpade to remove the excess soil/mulch surrounding the base and leave the healthy spoke-wheel roots exposed, much like the trunk flare solution.
Note: Try to hold off on pruning away these low-hanging branches until after that consultation, as in some cases, lower branches may actually be a component of structural reinforcement. Trunk Wounds Say your tree recently experienced an impact from a lawnmower, construction machinery, incorrect pruning, or even a vehicle; a wound to the trunk may have been left behind that removed some of the tree’s protective layer of bark. Assess how much of the bark has come off the tree. If the bark is still firmly in place, then your tree is likely doing just fine. If sections of the trunk bark have fallen off, the tree is decidedly at risk of being not only unhealthy but could also be unstable. Call an ISA-Certified arborist as soon as possible to get your tree the help it needs to survive. Annual trunk diameter growth This one will obviously be a long-term tree assessment. At the start and end of each growing season, wrap a tape measure around the trunk of your tree and record your findings. If there is around or more than approximately 0.75 inches (or 2 centimeters) of growth, your tree is on the right track! This amount can vary by species and age of the tree. If your tree seems to only have expanded about 0.25 inches (or 0.6 centimeters) or less in the last year, a soil check by a tree professional may be a good next step. Perhaps a nutrient is lacking and may be negatively affecting the tree’s health. Something like MitoGrow might be just the solution!
