Purdue Landscape Report: These oak trees are showing the symptoms of smooth patch ( see below Figures 1, 2, 3). This condition is the result of a fungal infection that is restricted to the outer bark, causing it to slough off. The bark layer remaining is smoother and lighter in color than uninfected, normal bark.
Patches can vary from a few inches to a foot or more in diameter and may occur on branches as well as the trunk. Several fungi can cause this condition. A common species, Aleurodiscus oakesii, produces clusters of flat, disc-like spore-bearing structures on the surface of the smooth bark. These structures are gray or beige in color and are usually less than 1⁄2 inch in diameter (Figure 4).
The best time to see this interesting phenomenon in the forest is during wet periods in late winter before new spring growth begins, when the light gray bark stands out in the light penetrating the canopy. The fungal structures shrink when dry so will be more apparent following rainy weather.
The fungal structures may be mistaken for wood decay fungi, but because smooth patch fungi invade only the nonliving, outer bark tissues, they do not affect the health of the tree. No control measures are needed.

Purdue Landscape Report: The bitter winter cold has finally passed us (or has it? It’s hard to tell in the Midwest)! The days are getting warmer and longer, and that means the insects are coming out of their overwintering stages. As you prepare for your landscaping and gardening this year, are you implementing preventative measures for pests? Now is the time to think about those strategies to minimize the damage to your plants.
Preventing pest issues is foundational to integrated pest management. The first step is always to start with healthy and clean plants. Don’t be afraid to bring a hand lens to the store and check for those hard-to-see pests! You don’t want to bring a problem home. Next, remember that many pests will thrive due to improper watering, light conditions, or fertilization. Avoid these issues by reviewing the recommendations for your plants and consulting a soil test. (Read more about why soil tests are essential!)
Finally, which pests/diseases do you anticipate? What are the most common pests on the plants in your landscape? Perhaps you have had issues in past years and know what to expect. Review the biology of these pests and consider implementing preventative measures now. Let’s look at a couple of examples of frequent landscape pests and some management options you can add to your list of spring preparations.
Spider Mites
Spider mites overwinter on the host plant or in leaf litter. Around this time of year, cool season mites such as spruce mites and boxwood mites are the dominant issue. Check your plants now for these spider mites, and scout regularly to make sure populations aren’t getting out of control. A rainy spring will help keep the pressure low. If you have to spray, avoid chemicals that will harm natural enemies, which are vital to spider mite management. (Learn more about spider mite management: Spider Mites on Ornamentals; and check out the Purdue Plant Doctor Quick Guide: Managing Spider Mite Mayhem)
Bagworms
Bagworms overwinter as eggs in the bags left on the tree. They’re frequent pests of arborvitae, junipers, and several other trees and shrubs. Take action now to prevent an infestation in the summer that requires costly pesticides. Manually remove the bags from your tree and drown them in soapy water. (Learn more about bagworm management: Bagworms).
Lace Bugs
Lace bugs may overwinter as eggs or adults, depending on the species. They become active again in the spring, so now is a good time to check for these pests. Focus on the undersides of the leaves where the pests are found. Lace bugs prefer hosts planted in sunny areas with a lack of plant diversity, so consider including some flowering plants in your landscape to provide pollen and nectar to beneficials. (Learn more about Lace bug management from the Purdue Plant Doctor Quick Guide: Managing Lace bugs).
What pests do you encounter in the landscape? Take a moment to review their biology and your options for preventative management. Be proactive now and reduce your pest problems for the season ahead. Read the original article, Insects are waking up – are you prepared?

In this episode of A Woodland Management Moment, Purdue Extension forester Lenny Farlee discusses the regeneration of small forest openings. Even forested areas of an acre or less can offer excellent opportunities for growth. Light-loving species thrive in the center, while more shade-tolerant plants flourish at the edges. This practice enhances the diversity of your woodlands. Adequate sunlight is crucial for creating a well-structured opening. By regenerating light-loving species, you can also add valuable wildlife habitat diversity to your property.

Wild Bulletin, Indiana Department of Natural Resources (DNR) Fish and Wildlife: Each year, the Indiana DNR invites the public to provide feedback on the management of white-tailed deer via the Deer Management Survey. The electronic survey gathers opinions of deer management at both the county and state level, covering deer population management, trends in deer populations and other relevant topics such as chronic wasting disease (CWD), land access and equipment types permitted for hunting.
Anyone can sign up to receive the survey, if you have previously filled out the survey, you will automatically receive the survey in future years. Find more information at DNR: Deer Management Survey webpage.

In this edition of ID That Tree, Purdue Extension Forester Lenny Farlee showcases the unique features of prickly ash. The northeast member of the Citrus family (not the Ash family!) is a shrub with stout, paired thorns, reddish-brown buds and also has other traits shared in the video that makes it easy to spot out in the wild. This video contains nice close-up shots so you can identify this plant, which is native to Indiana and an important part of the habitat.
