A significant insect issue has affected boxwoods in several areas of Michigan, resulting in a quarantine for these plants. This quarantine has recently been expanded to include more areas of Michigan. If you have boxwoods on your property or were hoping to integrate boxwoods into your landscape design, you may wonder how this quarantine impacts you and your landscaping. Your landscaping professionals are always available to help you with the health of your plants, but some basics are essential to understand.
Boxwood shrubs were recently affected by a quarantine in Michigan. A new invasive insect pest – the box tree moth – had been discovered to have destroyed nearly 75% of European boxwoods. When a box tree moth infestation was found in November of 2022, a quarantine of all boxwood shrubs was implemented to attempt to control this invasive species. This quarantine impacted shipments to and from nurseries and prohibited transporting boxwoods from the quarantine areas into other areas. However, purchasing and planting boxwood within and outside the quarantine areas were allowed if the plants did not cross the quarantined areas. Plants within the quarantine areas have unique tags with a nursery license that show their origin and any treatments and they were allowed to be removed after planting.
Boxwoods were also identified as carriers of a boxwood blight disease; without proper treatment, the disease can spread to other healthy plants. Boxwood blight is a serious fungal disease that can attack and quickly defoliate boxwood plants. While fungicides can protect healthy plants, they cannot cure infected plants. Infected plants can spread the disease to other plants unless they are removed. Spores from this infection can be viable for up to five years, so quickly identifying and remedying any problems from boxwood blight is essential. In Connecticut, the losses were significant for nurseries and home landscaping, and Michigan is now facing a similar situation.
Transporting boxwood out of quarantined areas into non-quarantined areas is still prohibited, and it is essential to talk to your landscape experts about ensuring that your boxwood plants are healthy and safe. If you discover an issue with an existing boxwood, you should contact your landscape professionals to ensure it is properly documented and treated.
If you have boxwoods on your property, monitor them for both signs of disease or infestation. Water boxwoods are used at the roots to ensure that spores are not spread, and pruning equipment is sanitized between plants.
New varieties of boxwood, including the “New Gem,” “Freedom,”, and “Independent,” are considered resistant to the boxwood virus and invasive box tree moths. These varieties can be purchased and planted with no risk to the area. In addition, now that treatment options are available, two seasonal applications of the treatment can be administered to keep the plants safe. As these stems and branches are often used in decorative arrangements, ensuring that any greenery made from boxwood has been tracked and treated is vital.
The short answer is yes; it is possible to obtain boxwoods at this point in the boxwood quarantine as long as
If you are having difficulty obtaining boxwoods or simply want to avoid the species until the blight is remedied, there are a few alternatives that can provide a similar aesthetic appeal without the risk of infestation.
