white ash

White ash (Fraxinus americana) should be watered when the top of the soil has begun to dry. The frequency of watering depends on several factors such as the season, temperature, soil type, and the size of the root system. Generally, white ash plants should be watered about once a week during the summer months, but may need to be watered twice in hot, dry conditions. During the winter months, when the plant is dormant, water should be reduced to once every 2 weeks. Soil should be moistened until water begins to drain from the bottom of the container. Allow the excess water to drain before placing the container back in its original location.

White ash trees (Fraxinus americana) thrive in full sun exposures of between 8 and 10 hours of direct sunlight per day. This tree does best in higher light, but will tolerate some shade and can even do well in light shade. Plant white ash trees in an area with full sun exposure, at least with no more than partial shade. Additionally, plant white ash in a location that is exposed to prevailing winds that keep the foliage dry in order to reduce the incidence of disease.

White Ash (Fraxinus americana) should be pruned in late winter or very early spring before the new growth starts. Pruning should be limited to removing dead, diseased, or injured branches. It is best to remove no more than 1/3 of the overall canopy in a single year. Shaping or thinning should be avoided as it can open up the tree to disease. Pruning should only be done if absolutely necessary, since heavy pruning can cause more damage than benefit to the tree.
