Purdue Landscape Report: When I was a kid, if you’d asked me what my favorite season was it would always immediately be summer. No school, time for playing outdoors, swimming, hiking, and late nights playing flashlight tag. Now, if I ranked the seasons from worst to best, they’d be Summer in last, followed by Winter (yes, I choose winter over summer), and a tie between Spring and Fall. With the best temperatures, a mix of sun and rain/snow, and an explosion of colors from new blooms in the spring to the reds, yellows, and oranges of leaves before they drop in the fall, Spring and Fall are by far my favorite times of the year. Well, we are nearly to the autumnal equinox with temperatures beginning to drop and the onset of some fall showers as I write this article. With Fall on the doorstep, I’ve received a repeated question recently, “Is it ok to plant a tree in the Fall?”
The short answer to this question is, “Yes!” If you want to add some new tree canopy to your yard, then pick your spot, choose the appropriate species, call #811 before you dig, and get that shovel out. Fall has some excellent reasons to plant trees, two of which I’ve already mentioned, cooler temps and autumn rains. While Autumn tends to be the driest time of the growing season, evapotranspiration rates are generally lower than during the summer season. These conditions reduce heat and water stress on trees (but are not an excuse to not mulch and water your new tree). Another good reason to plant in the fall as opposed to Spring is that instead of amping up for growing, trees are powering down and putting resources into root growth and storage. This means better establishment for the root system and a head start on protection for next year’s summer heat and drought.
There are some points to take into consideration, though. Again, make sure to properly water and mulch your new trees. They need an average of 5 gallons a week per inch of stem diameter if weekly rain isn’t providing around 1” of water. Be aware of when the first freeze is expected. You want to make sure your new trees have at least 6 weeks in the ground before the first freeze/frost and can stop watering after the first freeze. Also, for tree selection/protection, avoid broad leafed evergreen trees as they can be damaged by cold desiccation and wrap the trunks of your new trees to protect them from sunscald and animal damage like rubbing from bucks during the rut.
If you keep these points in mind and continue caring for your tree for the next 2-5 years you should have a successful planting. If you have any questions feel free to contact me at bmccalli@purdue.edu or you can find an ISA Certified Arborist at the following link Find an Arborist.

Purdue Landscape Report: Many trees are planted for their beautiful fall color, especially in locations where the climate provides reliable autumn weather. I have said this multiple times during extension talks and conversations with submitters to the Purdue Pest & Plant Diagnostic Lab (PPDL), but I seem to have not experienced a ‘normal’ fall since moving to Indiana with how erratic the weather has been from year to year. Depending on weather conditions, such as high heat and drought, colors may develop early or may be duller for specific varieties than expected.
However, individual trees that begin to show fall colors earlier than expected (August, September, even early October) may be shouting out a proverbial cry for help. Plants will often show yellow or red foliage coloration during periods of stress, so this may occur at any point during spring, summer, or fall. Individual trees may also show fall coloration earlier than others of their species in the same area. Now is the time to keep an eye out for this kind of early fall color as it can give you a heads-up on issues you can expect next year.
When examining a tree with early fall color, I would recommend checking the following:
It is important to know the host species, but with the sheer volume of plant material available for sale in the nursery trade, it is even more important to know the cultivar that you are planting so you know what you might expect coming into the fall.

Tree-of-heaven (ToH), also known as Chinese sumac, varnish tree, or stink tree, is a large, rapidly growing deciduous tree native to parts of China. Tree-of-heaven was introduced to North America as early as the late 1700s and has since become invasive in most areas of the United States. Tree-of-heaven can be found, sometimes in abundance, in both urban and rural environments. The tree spreads through abundantly produced wind-scattered seeds from female trees, and sprout colonies arising from established trees, in some cases producing monoculture stands of the species. ToH has also been shown to produce allelopathic chemicals that can inhibit the growth of neighboring plants, providing an additional competitive advantage.
Tree-of-heaven is a serious threat as an invasive species in many habitats or untended areas. It can reach 80 feet or more, its growth rate outpaces most native tree species, and wind scatters seeds that female trees produce in abundance. Controlling ToH is a challenge. In this publication, Purdue University extension specialists and property managers explain herbicide options, application techniques and strategies to control and manage ToH.

Weekly Review, Division of Entomology & Plant Pathology, Indiana DNR: Will Drews, Indiana Department of Natural Resources (DNR) Nursery Inspector & Compliance Officer, shares in August Weekly Review email from the Division of Entomology & Pathology how state funded kudzu control program works.
As some of you may know, kudzu (Pueraria montana var. lobata) is an invasive woody vine that can now be found throughout the state of Indiana. It is referred to colloquially as “the vine that ate the south,” and if you took a drive through some southern states (e.g. Tennessee, Georgia, the Carolinas, etc.) right now, you’d see why. Kudzu has tremendous growth potential, sometimes as much as 1 foot per day. Some vines reach lengths of up to 100 feet. Because of this it is a detriment to Indiana’s natural resources and has been listed as a prohibited invasive plant under the DNR’s Administrative Code as per 312 IAC 18-3-16.
While part of the language includes that the landowner “must take efforts to eliminate this species in such a manner as is consistent with federal and state law,” the Division of Entomology & Plant Pathology has been leading a state funded control program where sites are treated on a rotating, priority basis to eradicate or suppress further spread with no cost to the landowner. Over the course of the next couple weeks, close to 50 sites around the state will be treated.
If you think you have seen a new kudzu population, please send me that information (photos and GPS coordinates or address) at my above email address. Together, hopefully we can combat this invasive vine across Indiana and protect our natural resources!
For more information regarding this invasive vine Kudzu see the Indiana Department of Natural Resources, Division of Entomology & Plant Pathology, Kudzu.

MyDNR, Indiana’s Outdoor Newsletter: The Indiana Cooperative Fish and Wildlife Research Unit, or CRU, that Purdue will host, brings together the U.S. Geological Survey, U.S. Fish and Wildlife Service, Purdue University, the DNR, and the Wildlife Management Institute.
Its focus will be on delivering actionable science addressing fish, wildlife, plants, and other natural resources in Indiana and beyond, including the connection between the health of wildlife and the health of people.
The CRU Program is results focused, bringing together natural resource managers and researchers to work as a team to address the most pressing natural resource management needs with science. As such, the partnerships formalized with the creation of CRUs lead to true co-production of research.
“The creation of this new unit is another milestone in the highly successful USGS Cooperative Research Units Program, and we are proud to join the state of Indiana, Purdue University, the USGS, Wildlife Management Institute, and others to address conservation questions facing Indiana and the region,” said U.S. Fish and Wildlife Service Science Applications Program Assistant Regional Director Craig Czarnecki. “We look forward to engaging with the students and professionals at Purdue University as we co-develop scientific research and support the next generation of conservationists.”
But CRUs don’t just tackle management needs. They do so while cultivating the next generation of scientists and resource managers. The new Indiana CRU will focus on education, training, and outreach related to natural resources vital not only to Indiana, but the Midwest and regional economies as well.
Like all CRUs, the Indiana CRU will consist of 2-5 federal scientists along with graduate students, postdoctoral fellows, and administrative specialists. Federal scientists will serve as faculty at Purdue University, teaching graduate-level courses, supervising graduate students and postdocs, offering workshops for students and cooperators, and conducting research on natural resources topics. Once created, each CRU formalizes research priorities, like aquatic conservation or wildlife disease. Indiana CRU partners will decide these in the coming months.
“We look forward to the tremendous opportunity that collaboration with the Indiana CRU will bring to our state and Purdue University,” said Karen Plaut, executive vice president of research at Purdue University. “It will have a direct impact on graduate education as well as research productivity and innovation.”

Purdue Landscape Report: Trees stressed by prolonged drought are more subject to attack by boring insects. This article provides tips and a video link on how to manage pines for borers.
Record breaking heat and sporadic rainfall during July of 2023 took their toll on landscape trees. Cone bearing evergreens, like white pines, are especially susceptible to drought and flooding. These environmental stresses reduce the ability of trees to defend themselves against boring insects. To make matters even worse, insect borers use their keen sense of smell to guide them to these stressed trees. Trees often take several years to recover from drought. Monitoring trees for early signs of decline is critical to a successful management program.
Early intervention can help you keep infested trees from becoming a breeding ground for borers that can destroy an entire planting. Trees that are more than half dead, or those whose needles are mostly yellow are usually too damaged to save. Removing these trees in late fall and winter removes the reproducing borers from the landscape before borers they can emerge to attack healthy trees. As an extra protective measure, insecticides can be applied on to the trunk to kill boring insects chewing into or out of the trees. Apparently healthy trees located near borer-infested trees can also benefit from a soil applied insecticides, like imidacloprid or dinotefuran applied in fall and early spring.
Figure 2. Fine powdery sawdust left by bark beetles and fine shavings of sawyer beetles are signs that a tree may already be too damaged to save.
Zimmerman pine moth (ZPM)commonly attacks pine trees in late July. Adult female moths lay eggs at the junction of tree branches and the trunk and winters in cracks and crevices. In early spring, when forsythia bloom, larvae bore inside the trunk and can girdle and kill branches and trees leaders. These are the two times of year that this borer is most susceptible to insecticides. Note soil applied imidacloprid is not particularly effective against ZPM. Spruces and most pines are susceptible to this borer.

Purdue Landscape Report: Stop me if you’ve heard this one…. A tree is in a slow decline year after year. You are called to your client’s property only to find the root flare well below grade.
Most professionals in the Green Industry have encountered this at some point in their career. The most common reason for the slow decline of trees in the landscape is due to the depth of planting and girdling roots. Deep planting can cause a number of deleterious problems, including an increase in circling/girdling roots restricting vascular tissue and decay of protective bark (Fig. 1). The vascular tissue in the bark is located on the outer portions of the trunk, while the anatomy of roots contains the vascular tissue in the center. This is why roots can graft with roots and stems can graft with stems, but also why roots can girdle the stems of trees (Fig. 2)
Figure 1. A tree that’s planted too deep can have bark decay from too much soil moisture around the trunk.
Figure 2. Root girdling can occur on trees that didn’t have a root correction during transplanting and/or being planted too deep. Restriction of vascular tissue in the trunk will decrease the amount of water and nutrients taken up by the tree.
Excessive mounding of mulch (aka volcano mulch) (Fig. 3) can contribute to tree decline, very similar to a tree planted too deep. It’s important to remember that keeping mulch several inches away from the trunk is imperative in tree health.
If a newly transplanted tree is planted significantly too deep, a faster decline can occur, especially in plants that can’t tolerate ‘wet feet’ (aka too much soil moisture) (Fig.4). In heavy-clay soils, the negative effects on tree health increase by creating a bath-tub situation by water not draining expeditiously after a rainfall or irrigation event.
