Among shade trees, maples are particularly susceptible and hence the name "Maple Wilt" often has been applied to this disease by arborists. Initial symptoms appear as sudden wilting, browning, and shedding of leaves on one branch or one area of the crown (Figures 1 and 2).
The green, leafy branches of a maple or ash tree can provide much-needed refuge from the sun during the hot days of summer. Verticillium wilt, a common but often overlooked disease, can destroy that beautiful shade by causing these trees to wilt and die, sometimes within a few weeks or months.
A selected list of resistant trees and shrubs include: apple/crabapple (Malus), beech (Fagus), birch (Betula), boxwood (Buxus), dogwood (Cornus), hackberry (Celtis), hawthorn (Crataegus), hickory (Carya), holly (Ilex), honeylocust (Gleditsia triacanthos), katsura (Cercidiphyllum), linden (Tilia), mountain-ash (Sorbus), ...
Red and sugar maples (A. rubrum, A. saccharum) are more resistant than Norway or silver maples (A. platanoides, A.
Diseases occur on maples in the landscape as well as those growing in natural woodlots and forests. Anthracnose, fungal leaf spots (including tar spot), powdery mildew, and Verticillium wilt are diseases that are usually encountered every year whereas leaf scorch is an occasional problem.
But if your maple contracts a disease, such as verticillium wilt, root rot, or sapstreak, don't try to DIY this job. Contact a local arborist for the best chance to save your tree and enjoy its beauty for years to come.
Trees and shrubs infected with Verticillium cannot be cured and will likely eventually die. However, you can extend the life of your plants by making sure that you water and fertilize them properly. Make sure established trees and shrubs receive approximately one inch of water per week.
Norway Maple (Acer platonoides)
The Norway Maple tree is the best choice for street plantings. This resolute tree is tolerant to drought and makes a powerful impact on its landscapes.
Signs of maple wilt include scorched-looking leaves and diseased branches with unhealthy leaves. Occasionally olive-colored streaks can be found in the sapwood.
Prune affected branches: The most effective way to treat trees and plants already affected by verticillium wilt is by pruning the affected branches. Pruning dead and damaged branches will help restore the vigor of the plant and prevent the fungus from spreading.
Typical symptoms include: • Sudden wilting and yellowing of leaves • Leaf scorch, browning (FIGURE 2), and dying of leaves • Failure of branches to leaf out in spring • Sparse and/or undersized leaves • Death of part or all of a tree Verticillium wilt also results in discoloration of water-conducting tissues in roots, ...
Laboratory experiments have shown that to kill V. albo-atrum in hop bine fragments it is necessary to maintain a temperature of 40°C (104°F) for at least 7 days, 45°C (113°F) for 12 hours, 50°C (122°F) for three hours, or 60°C (140°F) for 15 minutes.
Groups of plants resistant to verticillium wilt include gymnosperms, monocots, members of the rose family, oaks, dogwoods, willows, rhododendrons, azaleas, and others. Symptoms of verticillium wilt vary somewhat in different host species and also within species due to varying environmental conditions.
Depending on where you live, you may be able to control verticillium wilt through professional soil fumigation or other means. In warm climates, plastic-covered soil may reach temperatures high enough to suppress the fungi at fault.
Wilting may occur on only one side of a plant. Heavily infected plants can succumb quickly and if not removed can release the survival structures into the nearby environment where they will wait for the next host to repeat the cycle. The disease can spread from root to root and through infected seed (up to 13 months).
The October Glory Maple Tree is fast growing and disease and pest resistant. The green leaves turn orange and then true red in fall.
According to a US manufacturer of moringa health food supplements, gram for gram moringa leaves contain: Twice the protein of yoghurt; four times the vitamin A of carrots; three times the potassium of bananas; four times the calcium of milk and seven times the vitamin C of oranges.
Suitable maple trees for zone 3 include the following: Norway maple is a tough tree suitable for growing in zones 3 through 7. This is one of the most commonly planted maple trees, not only because of its hardiness, but because it withstands extreme heat, drought, and either sun or shade.
A maple or similarly large tree should not be planted 10 feet from a home. Even doing so for shade means the tree should be planted 20 or more feet from the structure. Planting 10 feet away means the limbs will most certainly be in a constant struggle with the house side.
Japanese Maple: A Beautiful and Safe Option
Additionally, its roots are non-invasive, making it an ideal choice for planting close to your house. You can choose from various cultivars with unique leaf shapes, colours, and sizes.
Make sure plants are properly watered and fertilized, and avoid over-crowding plants or exposing them to extreme temperatures or other environmental stressors. Monitor plants for signs of infection: Early detection of Verticillium wilt is key to preventing the spread of the disease.
