Weeping cherries (Prunus subhirtella “Pendula”), together with their lovely drooping boughs and oodles of springtime blossoms are a precious, shade-giving addition to any lawn. While they grow in U.S. Department of Agriculture plant hardiness zones 5a through 8b, like many trees, the weeping cherry is susceptible to burning in the heat of the summer. If you would like to shield your tree, it’s important to comprehend the causes and symptoms of burn and treatments and prevention.
Summer heat can burn a weeping cheery tree for many reasons. Too little water can weaken the tree’s normal vitality and make it susceptible to trunk, limb and leaf glowsoff. Heat canker — that will be extensive tissue damage, not a disorder — is another reason of burn, that happens when late-planted trees produce insufficient ability to protect themselves from sunlight near the base of their sensitive trunks. Infrequently, unseasonably hot weather will tax a tree past the way it can protect itself.
Weeping cherry burn symptoms also vary. With heat canker, the tree will develop a brown, dead-looking area near the delicate soil line of the back. Scorching from bleeding or dehydration may create discolored patches on the bark, or can lead to leaves that turn yellow-brown or appear withered on the exterior. In rare cases, the tree’s leaves can drop off entirely, leaving it bare at the height of summer, though not dead.
Unfortunately, super-hot weather is past your ability to repair. If you can, safeguard young weeping cherry trees with shade cloth. You can treat heat canker comparatively by simply ringing the tree with sod a foot or so up the back to cool and shield it from sunlight. Dehydration issues are also solved by simply making sure a tree contains an adequate source of water, and gets extra until its burn symptoms disappear.
Preventing burn in the first place may be your very best bet. Plant new weeping cherry trees once the days are still cool to allow roots to acclimatize and cause it to be more prepared to take care of moisture loss. You should also be careful to maintain pesticides and treatments from the tree when warm weather threatens, since the combination of chemicals and sunlight can be dangerous.
