Leaves float on every strong breeze, covering our walks and driveway just hours after we last cleaned them. The many different species of trees in our community almost guarantee that we will have a long season of managing fallen leaves and pine tags. Leaves may begin to fall in August or September, particularly when the weather is dry. And some trees hold onto their leaves until the following spring. So cleaning up fallen leaves is more of an ongoing...
A Mythic Forest The American beech, Fagus grandifolia, once covered most of North America from Canada to Mexico and from the Atlantic to the Pacific coasts. Before colonists cleared our ancient forests for farmland, large beech groves grew as part of the climax forest community. A single beech tree can live for centuries, and as it ages it surrounds itself with sapling trees growing as suckers from its relatively shallow root system, forming an expanding grove of graceful beech trees....
Our once shady front yard was left a bright expanse of coarse wood chips and mangled leaves after the arborists pulled out their heavy equipment and left, that hot summer afternoon almost a dozen years ago. A freak summer thunderstorm had harbored a waterspout or small tornado when it blew in from College Creek a few days before. Our first clue that something was wrong had been seeing the underside of a muddy root ball rising 8 feet or...
There is a special beauty in the form and structure of a bare tree after it has dropped its annual crop of leaves. Like the beauty of a classical statue, one can see the truth of its bones. Leaves, for all of their movement and color, veil the beauty of branches and buds. Looking at a bare tree is a study in pure potential. All of the tree’s life draws inwards to the wood and roots as...
The sweet fragrance of Magnolia flowers on a warm breeze announces summer in Virginia. But that wasn’t the case 400 years ago, before European colonists began exploring for interesting tree species, transplanting them to new areas, and exporting them back to Europe. The original native range of Magnolia grandiflora is only from the Carolinas south to Florida and westwards towards Texas along the Gulf Coast. Our iconic Southern Magnolia trees aren’t indigenous in this region, but they have since...
Water may be a blessing or a curse. Gardeners usually want abundant rain to nurture their plantings and generally have a back-up irrigation plan for dry spells. Providing the right amount of water for each plant is one of the keys to a gardener’s success. Working With the Water Cycle Just as leaves absorb carbon from the air, so roots absorb water from the soil. The water, and any chemicals or elements dissolved in it, may be stored in...
Q. My crape myrtles have splits on the bark. What is going on? A. Your crape myrtles appear to have sun scald. Crape myrtles, Lagerstroemia indica, are considered a relatively problem-free tree. The Clemson Cooperative Extension website cites the most common problems as powdery mildew, Cercospora leaf spot, aphids, Japanese beetles, sooty mold, and the recently recognized crape myrtle bark scale. Clearly, the photo of your tree shows no indications of any of these diseases and insects. Your tree likely...
Q: Something is growing on the bark of my tree. Is that a problem? A: It depends. If it is flat and looks rather lacy, it’s lichen and does not harm the tree. If the growth on your tree bark is shaped like a shelf and looks like a mushroom, it is a conk. Conks indicate that the tree has internal decay. Lichen is a symbiotic relation between certain types of fungi and algae. They have a very shallow attachment...
