Culture for Red Maple
Can thrive in many soil types and conditions. Can grow in very wet or dry soil conditions, but prefers well-drained, moist sites. Root growth responds to conditions, but is primarily shallow and horizontal and can interfere with the hardscape.
Concerns about Red Maple
Structural defects due to codominant stems. Relatively weak wooded and internal decay can be problematic. Gloomy scale on the trunk and structural limbs can lead to decline. Scale is most problematic in urbanized areas. Micronutrient deficiencies can occur in areas where soils have alkaline pH.
Management Practices for Red Maple
Frequent structural pruning is necessary to obtain a central leader and proper lateral branch development. Ensure proper pruning cuts are made so pruning wounds close rapidly to prevent extensive decay. Avoid wounding the stem. Micronutrient applications may be necessary to green up the foliage until soil pH can be modified. Insecticide applications for scale should be applied when immature scales (crawlers) are active in late spring/early summer (6-8 weeks after leaf emergence).
