Is it possible to fall in love with a genus of plant? Absolutely. Some flowers appeal to us so persistently that we respond to them in ways that don’t quite make sense. Their pull on our imagination, our affections, and yes, our resources, defies reason. Across horticultural history you’ll find characters who left their home continents behind to collect favorite plants. You’ll find those who quit their day jobs to breed and grow them full-time. And you will find smitten...
Q. I have heard that Nandina is poisonous to birds. My community has planted many Nandina plants. Should we remove these plants to protect birds? A. It is true that Nandina (Nandina domestica) berries contain cyanide and are, therefore, highly toxic to birds and other animals. However, the only well documented case of birds dying from ingesting Nandina berries occurred in April 2009 when dozens of Cedar Waxwings were found dead in Thomas County, Georgia. The University of Georgia, College...
Q. What are the strange marks on my holly tree? A. Those strange, rectangular shaped bare spots in the bark were made by sapsuckers, a type of woodpecker. While these birds eat insects, fruits, and nuts, they also enjoy tree sap. Here in eastern North America, the most common and destructive of these birds is the American yellow-bellied sapsucker, Sphyrapicus varius. These are migratory birds that feed in Virginia when the sap begins to run in March, and then again...
Q. Why are mushrooms in my yard? How can I get rid of them? A. Mushrooms tend to pop up in the fall due to shady, cool, and moist conditions and the availability of organic material in the lawn. The mushroom is the fruit of an underground feeding network (mycelium) of fungal threads (hyphae). Fungi feed on decomposing plant material and make that material accessible to the grass growing in the yard. Mushrooms do not damage the lawn and can...
Q. What is going on with my weeping redbud? Most of the leaves are covered in spots and many have black areas. A. The spots and blackening areas on your weeping redbud appear to be fungal infections that probably include anthracnose. It is not unusual to see redbud trees (and almost any deciduous tree) in the fall with fungal infections showing up as spots and blackened areas on the leaves. This seems to be especially common on redbud trees. The...
Did Santa bring you a potted plant for Christmas? Or maybe a neighbor dropped by with a beautiful potted something to spread a bit of good cheer your way? Or do you always linger at the rack of holiday plants and wonder which ones you might be able to keep alive for a few weeks this winter? December and January are a great time to shop for plants. And this week, especially, after Christmas, you’ll find some good values...
You may be ahead of me on this one, but the picture that came to mind when I first saw the term ‘Carbon Garden’ in the January 2021 issue of Horticulture Magazine wasn’t very pretty. In practice, a carbon garden is not only beautiful, but this garden style proves easier to maintain than many others. A Quick Summary of the Science Like other elements, carbon is an atom that can manifest as a solid, in a liquid, or...
November and December in Williamsburg bring beautiful fall colors to my backyard which include my blooming camellias. There are two popular types that are late fall/winter bloomers, sasanqua and japonica camellias. Although caring for them is easy, there are a few things I recommend you do to encourage healthy plants. Your efforts will be rewarded with beautiful flowers and luscious greenery. Mulch Add three to four inches of natural mulch to protect your plant from the cold winter winds. Mulch...
Did you notice bees and other insects feeding later than usual last year? And did you notice how many were out feeding on warm days last winter? Our roller coaster weather affects insects, birds and other animals. They may be out and about on warmish days in months when we don’t expect to see them. And, of course they are hungry! Increased activity translates into an increased need for calories. Providing winter forage for pollinators and birds presents gardeners...
“Leave it be.” Words I heard with some frequency growing up…. This simple bit of advice may be just the wisdom we need whether baking, navigating relationships, or preparing the garden for winter. “Leave it be” insists that we quiet our urge to interfere with natural processes. It asks us to step back and observe; to allow for a solution to unfold on its own. Some gardeners feel compelled to tidy up the leaves and sticks as they fall,...
