Juglans nigra
Plant Details:
Plant Type: Deciduous Tree
Plant Family: Juglandaceae
Plant Description: Large deciduous tree valued for its hard wood. Nuts are edible and can be messy when they fall. Black walnuts produce a natural growth inhibitor that can cause plants beneath it to grow slowly or die. Usually best planted in large open areas such as parks. May drop its leaves in extreme drought situations.
Maintenance:
Maintenance Type: Tree - Deciduous
Plant Care: Tree - Deciduous (single-stemmed woody plants that lose their leaves every winter): Prune regularly to promote health, provide air circulation, maintain a desirable shape, and to remove dead or damaged branches. Pruning is best done in late winter to early spring for most trees. With spring blooming trees, prune after the blooms are spent. Choose species that are resistant to pest damage. Monitor the tree for pests, diseases or other ailments on a regular basis. Protect the trunk especially where maintenance activities, such as mowing, may cause damage. Newly planted trees in areas with high exposure should have the trunk protected during the winter.
