![]() The beauty of this tree makes up for the extra effort required to grow it. Probably best in partial shade if planted in the south. Leaves will scorch during dry summers unless provided with some irrigation. It does not tolerate extended drought or other environmental stresses in the south or in poor soil (moderate drought-tolerance in sandy loam) but will grow in sun or shade. The tree is hardy, grows very slowly to 25 or 30 feet tall, but, unfortunately, is difficult and expensive to propagate. If you can find it, plant it by a patio or other prime location and light it from below for nighttime enjoyment. The multi-stemmed habit, unusual leaves, and wonderful bark makes this a prime candidate for specimen planting in any commercial, institutional, or residential landscape. It does not usually produce surface roots and should not present a mowing problem unless allowed to assume its characteristic multi-trunked, low-branching form. The tree is hardy and grows very slowly to 25 or 30 feet. Paperbark will grow in all light conditions from full sun to deep shade it has moderate drought, salt aerosol, and soil salinity tolerance. Elongate, oval fruit with a hard brown husk are 1-3 inches long do not attract wildlife, neither do they present a clean-up problem. Inconspicuous green flowers appear in spring. It grows to 25 feet tall and nearly as wide, but often takes a vase shape or upright form with an open crown. Look for small (smaller than BB size) holes in the bark.Hardy in USDA zones 4 through 7, this tree can be used in Bonsai containers or above-ground planters, or planted in buffer strips around decks or patios. Ash trees are susceptible to ash borer which can kill off branches or entire trees. There could be disease organisms attacking the limbs. Chemicals can also cause browning on the edges of leaves. ![]() Salt or herbicides can cause limbs to die. Typically occurring in the fall or in late spring when temperatures are very cold and the tree has not hardened off for the winter or in the spring when it gets very cold after the tree has begun to come out of dormancy. There can be numerous causes of dying branches. This generally heals over rapidly and doesn't cause further damage. When trees, particularly maple, grow very fast the bark on the trunks can split open. Sunburn can cause limbs to also die off on those sides of the tree. Fall color can be from bronze to russet red to bright red, especially if you get a hybrid. This is a perfect small tree with incredibly interesting coppery, curling, and flaking bark, and small trifoliate (3 part) leaves. If the cracking is on the south or west side of the tree it is probably due to sunburn. Paperbark Maple seems to be on everyone’s favorite list for small interesting trees. Typically cracking bark is caused by 2 different disorders. Let me know what you see specifically about the condition of the trees and I will be pleased to offer further assistanc The interior of the bud should be green, if alive. ![]() Pick some buds from several branches and split them length wise with a thumbnail. ![]() The buds will be obvious on the sides of the branch and on a maple tree opposite of each other. Also check the buds on the branches for life. If the area underneath is green, the branch is alive. What conditions of the trees indicate they are dying? Are there areas of dead branches on the tree or dead branches falling from the tree? Are there decayed areas on the trees? Have the trees leafed out? Did you notice the trees looked unhealthy last year? If so, in what way? Has there been any change to the area around the trees? You can check to see if a branch is alive by lightly scraping the surface with a thumbnail. The key then is not the lichens but what is causing the decline of the tree. If the canopy of the tree declines, there are fewer leaves thus allowing more sunlight to penetrate the tree causing an increase in the growth of lichens. Lichens can also indicate that the tree is in decline. Actually lichen growth on a tree indicates the air quality in the area is good. They are merely using the bark as a place to live and are not affecting the health of the tree. Lichens are a complex relationship between a fungus and algae. The algae is caused by moisture on the bark. The moss usually grows on tree bark due to shade. None of these would cause the trees to die. There are several things that may be causing the green splotches on the tree trunks. ![]()
