Rusty Junipers

Junipers in southwest Ohio are being garnished with tangerine tentacles and orange goo; the calling cards of rust fungi. The three fungi producing the colorful displays belong to the genus Gymnosporangium and each must alternate between a member of the plant genus Juniperus and members of the rose family (Rosaceae) in order to complete their life cycle.

Wilting Buckeyes

Wilting buckeyes may sound like an Ann Arbor dream, but I'm not talking about our beloved Silver Bullets. I'm referring to the symptoms caused by the Buckeye Petiole Borer (Proteoteras aesculana) on its namesake host.

Calico Scale is Puffing-Up and Pumping Honeydew

Overwintered calico scale (Eulecanium cerasorum) females are now "puffing-up" and pumping out impressive quantities of clear, sugary honeydew in southwest Ohio. The appearance of the globular, helmet-shaped females coupled with complaints of trees oozing sticky goo makes this life-stage important for detecting new infestations. All other life-stages are much less obvious.

Sneaky Common Chickweed is Going to Seed

Common Chickweed (Stellaria media) is a European winter annual that is now found world-wide. Winter annuals are sneaky weeds. They produce seeds in the spring then plants fade away prior to the summer season; out of sight, out of mind. The seeds dodge spring applied preemergent herbicide bullets because they do not germinate until the fall. The resulting plants grow below our radar throughout the fall, winter, and early spring when we pay little attention to what's going on in our lawns and landscapes.

Tigers are Prowling Ohio Woodlands

My good friend Brad Bonham told me about a conversation she had with a landscaper over the weekend who declared they were seeing Emerald Ash Borer (Agrilus planipennis) (EAB) beetles mating in a woodland in southwest Ohio. Of course, as she noted, it's way too early for EAB adults to be on the wing; full bloom of black locust (Robinia pseudoacacia) is a good phenological indicator for EAB adult emergence.
