Timing of defoliation, health, and type of tree influences the likelihood of recovery and survival
Now is the time to look for Japanese beetle injury to see if action is needed to protect your plants.
Gypsy moth has many homeowners scrambling to deal with large caterpillars stripping leaves from their trees. Don’t panic! We explain how to manage it.
Scale insects are difficult to manage because their waxy or sticky covering protects them from insecticides. Learning about their life cycle can help you protect your plants.
This article, and many others, will be presented at the 2018 Purdue Turf and Landscape Field Day on July 10th. Registration is open and available online: https://www.mrtf.org/event/turf-and-landscape-field-day/?event_date=2018-07-10 Here is the lineup for the field day. A cultural weed control method is one that involves steps to reduce or eliminate weeds via maintenance techniques. In landscapes, the most common type of cultural control is mulching. Mulching provides many benefits in the landscape, including moisture retention, temperature consistency of the root zone, improvement of soil structure, addition of organic matter, aesthetics, and, perhaps most important, a significant reduction in weeds. Mulch prevents weeds a couple of different ways. Many weed species require sunlight for germination to occur. By shading the soil beneath the mulch, weed seeds that require sunlight will not begin to germinate. The other way that mulch prevents weeds from germinating is by providing large air spaces (macropores) between the pieces[Read More…]
As we move into summer it is time to be on the lookout for Japanese beetles. They are already being reported by Indiana Nursery Inspectors in Southern Indiana. Continued warm weather and precipitation should bring them out throughout the rest of the state over the next few weeks. See our bulletin Japanese Beetles in the Urban Landscape for tips on controlling them without killing pollinators.
After surveying 72 sites across Indiana and Illinois in the coldest part of our states where bagworms are found, we determined that while many bagworms were killed, enough survived to keep bagworms near the top of our landscape problem list. NOW is the time to inspect your plants for bagworms. For details on the cold snap and how to control bagworms see this article in the February issue of the Purdue Landscape Report. https://www.purduelandscapereport.org/article/824/
Spotted lanternfly is a nasty new pest that may soon be in Indiana. It weakens a wide variety of trees, covers them with mold and threatens fruit and grape growers.
Boxwood leafminer damage is widespread. It’s not too late to protect boxwoods from boxwood leafminer and protect pollinators.
Understanding plant and pest development can help provide the most effective and timely approaches to managing pests.
