One way to check to see the health of your tree is by taking a key or pair of pruners and to scrape a very small piece of the bark off on the limb of the tree. ( Please be careful ) Make sure you test multiple limbs of the tree. Now if your tree is alive and healthy you will notice a dark or light green layer underneath the bark. The darker the color the healthier it is and the lighter the color green means your tree’s health is failing. If your tree is on the verge of dying or failing health it will be a very light green. If your tree is dead there will be no green layer and the limb will snap in half very easily. At this point, you need to see why the tree is not doing well and fix asap or just call us.
