American elm

Ulmus americana

The American Elm (Ulmus americana) is a deciduous tree native to eastern North America and grow up to heights of over 60 feet. Its majestic branches extend in a vase shape forming a vase canopy at the top, making it a popular landscape tree. Its bark is gray-brown with ridges and furrows, and oval leaves sometimes appear in alternating sets of two. Its flowers are small and bloom in early spring. In autumn, seeds with attached wings disperse from the tree in a process called “twirling”. The American Elm is naturally resistant to Dutch elm disease, making it an ideal tree for anyone looking to add an ornamental and disease-resistant addition to their landscape.

watering

American elm trees should be watered once per week, or at least every 5 to 7 days. Water deeply so that the roots receive a thorough soaking. Water in the morning hours, when temperatures are still relatively cool and the sun is not as strong; this helps reduce water evaporation. Depending on the size of the tree, use at least 10 to 20 gallons of water every time it is watered. Allow the water to penetrate the soil around the tree's roots as this will encourage deep and healthy root growth. If the soil is dry, increase watering slightly to ensure adequate hydration. Overly saturated soil can lead to issues like root rot, so be sure to monitor the soil moisture levels.

sunlight

American elm trees prefer full sun for optimal growth. For healthy growth, they should receive at least 6 to 8 hours of direct sunlight a day. During the summer, a partially shaded spot is also suitable as long as the tree receives at least 4 to 6 hours of direct sunlight daily. During the winter, American elms should receive full sun to remain healthiest.

pruning

The American elm (Ulmus americana) should be pruned during the winter when the plant is in its dormant season. Pruning should be done carefully and the removal of dead or diseased branches is necessary to avoid the spread of disease in the tree. Pruning should be limited to removing no more than 1-third of the plant’s total foliage to ensure the desired shape and size of the tree. Additionally, crown thinning should be done to promote the density of foliage and improve air circulation between branches. This will create more space for better light penetration, resulting in healthier growth.
