Healthy Trees from the Ground Up

Image
Everyone looks up when observing trees. However, you’ll often find arborists looking down! That’s because when it comes to assessing tree health, one of the most critical factors is a healthy root system. Focusing solely on noticeable issues in the canopy, like yellowing leaves, may cause you to miss the culprit responsible for those issues, which is often found below ground. Common Root and Soil Issues There are many concerns for tree roots. Disease is often found in the root system. One widespread example is root rot. Trees with root rot may have stunted growth, discolored leaves or dieback, but the real problem lies underground. Another frequent source of injury to the roots is damage from lawnmowers or other yard equipment.  For example, driving over an exposed tree root can result in irreparable harm, making it difficult for the tree to transport water and nutrients from the root system. Problems also occur when you plant trees too deep or pile too much mulch against the t

Buttonbush: A Plant that Thrives in Wet Soils

Image
It’s tough to find garden plants that thrive in wet soils or areas where there is standing water. You want a plant that can live in less than hospitable conditions while also looking great. In these instances, buttonbush ( Cephalanthus occidentalis ) may be your plant.   Characteristics Buttonbush is a small to medium sized shrub that can reach a height of 10 to 15 feet tall with a medium spread of 8 to 10 feet. It is sometimes called button willow, honey bells or honey balls. This multi-stemmed plant has leaves that come in pairs or in threes. The leaves are a glossy dark green with a narrow, oval shape. Further, they have smooth margins and a pointed tip that rounds to a tapered base. When it is happy, buttonbush produces long-lasting white or pale pink flowers. The flowers are unique. They have a round shape and a pincushion-like appearance, like a spiky ball. As the flowers fade, they mature into reddish-brown fruits that persist into winter. Buttonbush is a wildlife lov

Choosing a Tree for Your Landscape

Image
Mistakes are easy to make when choosing a tree. Most of these are related to misinformation regarding a tree’s size when full grown. It’s also common to see mishaps like full-sun plants tucked into shady corners. Planting a tree should be fun and exciting. Unfortunately, mistakes ultimately often lead to disappointment. Planning and careful consideration are not only necessary at the time of planting, but before as well. A successful tree planting starts with the right tree. Planting Goal With so many choices about species, size, cost and other factors, it’s easy to get bogged down before you even get to the most important question. Prior to making any decisions, the first thing to ask is, “what is my goal in planting a tree?” Some typical tree planting goals are improving privacy, beautifying the landscape (flowers, etc), increasing shade, or establishing a family heirloom. Establish a goal and you will have an easier time making a choice about the best tree. Location, Locati

Codominant Stems and Reducing Tree Failures

Image
Research shows that trees with multiple (codominant) stems have a higher likelihood of failure than those with a single stem so it is important to address this trait – the earlier, the better. To explain, codominant stems occur when two or more stems grow upward from a single point. This creates a v-shaped crotch that typically indicates a structural issue. Tree trunks need wood tissue to hold the tree up, particularly in windy conditions. When codominant stems exist, there is less direct connection of this wood tissue, creating a weak point in the tree that is more likely to fail. In some cases, bark on the side facing the other stem is captured in between the stems (included bark or bark inclusion). Generally, this makes the attachment even weaker. Preventing Codominant Stems in Young Trees The best way to prevent codominant stems is to prune the tree while it is young. Start a year or two after planting and continue as the tree grows. Structurally pruning a tree several tim
