Name This Tree

This tree is not usually thought of as an ornamental, although it’s bark has an interesting interwoven texture with a bright red-orange hue. It’s form is almost always non-linear which makes one wonder how Native Americans made bows from it. It is dioecious and produces softball sized green-yellow fruits that have a strong citrus smell. Some say that if you cut the fruit in half and place it at the corners of the house, it might repel insects. The tree was a favorite of Thomas Jefferson and Lewis and Clark distributed it across the West; thereafter, it was important in fencing the Western landscape because of its durable wood. The tree is naturalized throughout the United States. What is it?

Urban Trees Face “Survivor” Style Challenges

Urban trees are taken away from their usual circumstances and placed in an unfamiliar and challenging environment. Recent studies have been undertaken with the hope that understanding that disparity and incorporating as much of their natural habitat as possible in this new environment might help muncipalities more successfully integrate trees into heavily populated areas.


Pruning Young Trees

2014-11-05 15.10.442

Proper pruning starting when trees are young is essential in developing a strong tree with desirable form. Start pruning a young tree after the first one or two growing seasons after it has adjusted to its landscape. Pruning young trees should focus on the 5 essential steps to structural pruning: (1) clean dead branches, (2) establish a central leader, (3) establish lowest permanent branches, (4) establish scaffold branches, and (5) establish temporary branches to help create stem taper (which will make the tree stronger. A tree that has been planted in an appropriate location and pruned starting at a young age will result in a healthier mature tree that is less expensive to maintain.
