Fraxinus Lanuginosa

Water Japanese ash daily after planting to encourage root growth. Once the plant is established, you can reduce watering to once a week. During dry summer weather, increase the frequency of watering as needed. Before winter arrives, water the plant one last time to help it sustain through the cold months. Be careful to avoid overwatering, as this can lead to root rot.

Prune Japanese ash trees in the fall to promote healing before winter dormancy and to prevent snow damage. Young trees need annual pruning, whereas mature Japanese ash trees should be pruned every few years. Regularly remove dead or crossed branches to improve air circulation and reduce the risk of disease. For tall Japanese ash trees, consider hiring a professional for pruning.
