watering

White Ash (Fraxinus americana 'Rosehill') should be watered thoroughly once a week. Make sure that the soil is moist to the touch and not dry. Allow the top inch of soil to dry out in between waterings before watering again. If you see leaves wilting or dropping, adjust the frequency of watering to ensure the plant is getting enough water. In summer months the plant may need more frequent watering, for example, every 4-5 days. In winter, the plant may need less water, perhaps no more than once every 2 weeks. Make sure to water more often during unusually warm or dry weather.

sunlight

White ash (Fraxinus americana 'Rosehill') needs full sun exposure to thrive. During the growing season, this species of plant should receive at least 6 to 8 hours of direct sunlight every day. As the season changes and daylight hours decrease, White ash can tolerate some shade and may be able to do well with just 4 hours of sunlight. In winter months, White Ash should receive 2 to 4 hours of indirect sunlight each day.

pruning

White ash (Fraxinus americana 'Rosehill') should be pruned in late winter. The amount of pruning should depend on the desired size of the White ash tree. Reduce the top slightly to promote a dense form. Pruning should also remove any crossing branches to allow sun and air to get to the inner canopy. Prune no more than 30 percent of the live crown in a single year to avoid stressing the plant. Pruning should also be done to remove dead or damaged branches and to encourage healthy growth.
