We hope you enjoyed the beautiful weekend! As our teams maintain your property they are always watching for signs that plants are struggling or that pests or disease are present. Our goal is to treat situations as soon as we are able in an effort to mitigate any damage to your landscape. This year, because of a mild winter and excessive moisture in May, we are exceptionally mindful since we expect more challenges than normal, and will be working diligently to minimize any adverse effects.
For those that are currently contracted for Plant Health Care Services, be assured we are treating issues as they arise.
As part of our effort to keep you current on issues that affect your landscape, we have a couple of updates regarding pests our teams have become aware of on several properties.
First, the periodic Cicada is appearing in landscapes throughout the Chicagoland area, and Illinois more broadly. When they emerge from the ground the mature female deposits her eggs in tree leaves. As these eggs hatch, the nymphs drop to the ground and burrow in the soil to feed on root sap, emerging either 13 or 17 years later, bringing their life full circle.
You may have already noticed their sound, and while noisy and maybe a nuisance, there is no effective treatment other than picking them off by hand or washing them away with a garden hose.
Second, we have Leaf Beetles on viburnum that are turning healthy foliage into lacy leaf skeletons. The beetle’s life cycle follows one full year. Emerging from the soil in spring or summer (depending on weather), the adult females lay eggs throughout the summer in leaf holes they’ve chewed. Next year the eggs hatch and the larvae continues munching away on viburnum leaves through early spring, then crawls back into the soil to pupate and emerge later in spring or summer, completing the cycle.
To minimize their number and damage it is recommended to cut out affected twigs. For more extensive issues, treatment can be applied to further reduce their impact. If any problems are found on your property, your Account Manager will contact you with a plan of action.
