The Autumn Blaze maple is a popular in tree in modern landscape developments in Canada and the US. It is mainly favourited for its rapid growth and soil adaptability. Under ideal conditions, this maple can grow easily over 3 feet per year and in the poorest of soil conditions, in arid and even polluted areas. The overall growing size is about 55 feet tall and 40 feet wide at maturity. It is native of North America and has a hardiness range from Zone 4 to 9 in Canada.
Structural Weakness
Despite the tree’s popularity, the Autumn Blaze maple has serious issues which are well known among arborists and home owners. The tree, which is cultivated from red and silver maples, develops an extremely weak structure with its rapid growth. Thin, elongated weeping, brittle branches break easily in strong winds, heavy rain, or snowfall. It takes little force to accidentally damage a young specimen during handling on transport and planting process due to its weakness. Injuries from broken branches are open ports for pathogens, fungi and pests to enter. As a result, the overall aesthetics, structural integrity as well as vitality and longevity of this tree are compromised.
To mitigate the structural weakness of Autumn Blaze maples, proactive measures, such as regular pruning and trimming must be applied to reduce the risk of failure. In some cases, cabling or bracing systems may have to be employed to provide additional support to weak branches or alleviate stress on heavy limbs. Considerations should be given to the planting locations of Autumn Blaze maples in the landscape. They should only be planted where they are shielded from windy and stormy weather conditions. Regular inspections by certified arborists are crucial for identifying early signs of problems and to allow for timely interventions. In extreme cases, arborists may recommend a complete tree removal where risks to property become significant.
Root Rot
In addition to the structural weakness, Autumn Blaze maple trees are highly susceptible to root rot, a serious fungal disease. This condition poses a significant danger as it gradually deteriorates the tree’s root structure, hindering its ability to effectively absorb vital nutrients and water. Consequently, the overall health of the tree declines over time, making it more vulnerable to other issues and environmental pressures. To combat root rot, these maples cannot just be planted in any soil condition as is commonly thought. As with most plants, planting locations with well-drained soil are necessary to avoid the development of problems from the start.
In conclusion, it is evident that this popular tree is by far not as perfect as it is marketed by growers and nursery retailers. Unlike with most other maple trees, the Autumn Blaze maple requires extra care and special management to ensure longevity and safety to people and property.
