In this episode of “A Woodland Management Moment”, Purdue Extension forester Lenny Farlee discusses the influence of a topographic characteristic on the landscape and that is aspect: the direction that a slope faces. There are some significant implications on the moisture levels of a site and thus, the tree species that could thrive on that site. The video outlines how aspect can affect factors in an environment and how best to utilize this information as a landowner. Watch to learn about site growth and species information as a casual viewer or a landowner!

Purdue Landscape Report: An unfortunate question I am sometimes asked is similar to this: “I lost my prized shade tree! What can I plant that will grow fast and give me shade?” While there is no instant fix to this scenario, let’s review a few trees that might be better choices here in northern Indiana.
One obstacle to consider is that many of the fast-growing trees are also fast-dying, meaning that, relatively speaking, they are not long-lived for trees. We’re already behind the 8-ball in our highly manipulated landscapes because we know that trees in landscapes tend to live much shorter lives than trees in their unmanipulated natural habitats.

Figure 1. Honeylocust is a fast growing tree that performs well in urban plantings (Image from Purdue Landscape Report)
That said, here are a few trees to consider. I would still encourage homeowners to invest some time in researching the trees that they are considering. There are pros and cons to almost every tree, and there isn’t room in this article to fully explore all the advantages and disadvantages of each tree. Additionally, I will not be getting into detail about all the cultivars available.
Let’s start with our state tree, the Tuliptree (a.k.a Tulip-poplar or Yellow-poplar). Tuliptrees can become quite large and offer a pretty yellow fall color. They prefer deep, rich, well-drained soils.
If maples are on your mind, a couple of options would be Red maple and Freeman maple (a hybrid cross of Silver maple and Red maple). Red maple has more moderate growth. The Freeman maple is a faster grower and has stronger wood than one of its parents, the Silver maple. These maples do best in well-drained, slightly acid soils, but will tolerate a variety of soil conditions.
Northern catalpa is a fast grower, but dealing with the fruit litter, a long seed pod, may be a deterrent for some locations. It has large, heart-shaped leaves. It would grow well in moist sites.
Common hackberry is a fast grower, but it is susceptible to galls on the leaves (from a n insect), and limbs can become susceptible to wind and ice damage. It tolerates a wide variety of soil conditions. Thornless honeylocust is widely adapted to different soil types. Honeylocusts in the wild produce large thorns. The Thornless honeylocust is adapted to landscapes and allows dappled sunlight to reach turfgrass, so that it thrives more than it would under a tree that provides heavy shade.
Sweetgum is also a fast-growing shade tree with brilliant fall colors. It has a star-shaped leaf. One drawback of sweetgum is the spiny seed capsule. This fallen fruit can make walking in the yard barefoot a painful experience.
Eastern cottonwood is the tree on record for the fastest growth rate of any tree native to the U.S. However, those with cottonwoods in their yard can tell you that the cottony seed mass shed in the spring sticks everywhere. It can be a mess. Plus, cottonwood can shed limbs frequently, especially after storms. This tree is commonly found along rivers and streams, so it not surprisingly prefers moist soils.
Also found along rivers and streams, American sycamore is a fast-growing tree in some landscapes. However, it can be a messy landscape tree, shedding bark, leaves, limbs, and fruit nearly year-round. The large fallen leaves can smother grass if not mowed or raked. It is also sensitive to a spring disease called anthracnose, which can cause defoliation and twig death.
Wild black cherry may be another good choice. Although it may not be available in some nurseries, it can be grown from seed. It prefers rich, moist, well-drained soils.
A couple of faster-growing oaks to consider are Pin oak and Northern red oak. Pin oak would be better suited to slightly wetter spots, while Red oak would work on a wider variety of soils, preferring rich, moist, well-drained sites. Pin oak is susceptible to iron chlorosis (yellowing leaves) on alkaline soils.
Finally, American basswood also prefers rich, moist, well-drained soils and is somewhat shade-tolerant. This tree can grow quite tall and provide excellent shade.
In your research, find out how large the tree you will be purchasing will get. One common planting mistake is locating trees too close to structures. Consider the mature size when placing it in the landscape.
Time your spring planting near Arbor Day, the last Friday in April.

Purdue Landscape Report: Spring is just around the corner, green spaces are beginning to wake from their winter slumber, Earth Day and Arbor Day are a little over a month away, and people are ready to get outside with planting on their minds. But before you go and get your tree(s) for planting, there is quite a lot to think about. Every tree is an investment, and if properly cared for, will outlast us and potentially future generations. So, what goes into planting trees, especially large trees?
One important note for successfully planting any tree is thinking about your goals, or what you want out of a new tree. In the case of large trees, the first thing that usually comes to mind is shade. Having a large shade tree to block the sun on your home in hot summers can significantly reduce power consumption from air conditioning. Large shade trees also give us great locations to play, picnic, or relax outside in our backyard, at local playgrounds, or parks. Given the space and care to grow, they can create wonderful local environments and beautiful aesthetics, driving down neighborhoods and city streets. The right species can benefit local wildlife with food production and habitat improvement.
When you know what you want, you can begin to assess your site to see if you have the right space for your future tree. Large trees require larger spaces. If your tree survives to a mature size, will it interfere with anything else around it? Are there utility lines above or below your planting site? What is the proximity to homes, buildings, or other structures? Will it obstruct road signs, lights, or line of sight? Will falling leaves, nuts, or fruits adversely affect anything around the tree? What is the quality of the soil: pH, well-drained, wet, clay, loam, or sand? A poorly assessed planting site could lead to a doomed planting project by placing the wrong tree in the wrong place.
Once you have your goals in mind and know what type of site you have, you can begin to consider what species you may want to plant. A couple of good resources for considering species selection in the Midwest include your local extension offices, reputable nurseries, and online resources like the Morton Arboretum. In the case of large shade trees, we all would like to have our shade now, but trees take time to reach mature heights. That being said, some species grow a little faster than others. Faster-growing trees that grow well in urban settings include:

Next, we have some examples of trees slowing down to moderate growth:

These suggestions are a small sample of large shade trees that can grow well in different urban settings. Remember to think of what the overall goal is for your planting and to assess your site to make informed species choices. With proper forethought, you can make a resilient landscape that your trees will be able to survive in for years and years. If you still have questions, you can contact your local extension office or find an ISA Certified Arborist at Find an ISA-Credentialed Arborist.

Purdue Landscape Report: We are often the bearers of bad news when a new exotic insect species is discovered in Indiana. This time, however, we have some good news to share. Agrilus smaragdifrons, a beetle that feeds exclusively on Tree-of-Heaven (Ailanthus altissima), was detected in Indiana last year in Allen County.
You might notice that this beetle belongs to the same genus as the infamous Emerald Ash Borer (Agrilus planipennis) (EAB). Indeed, the two species look quite similar, although there are subtle differences in their striking metallic coloration. While Emerald Ash Borer is a vibrant green from head to wing, A. smaragdifrons has a golden-red head and thorax with green to black-green wings (Fig. 1).
This beetle has been present in the United States for several years, with the earliest record dating back to 2011 from a photograph taken in New Jersey that was uploaded to BugGuide.net. Subsequent detections occurred in several neighboring eastern states, often as bycatch during Emerald Ash Borer surveys (Hoebeke et al. 2017).
The life cycle of A. smaragdifrons also shares many similarities with Emerald Ash Borer. Although its life cycle under North American conditions has not yet been formally described, Hoebeke et al. (2017) summarize the beetle’s biology in its native Asian range based on Chinese literature (Xu and Yang 2007).

Figure 2. Agrilus smaragdifrons exit holes in Ailanthus altissima (Photograph by Patrick Perish, iNaturalist)
Females lay eggs in bark crevices during mid- to late summer, and newly hatched larvae burrow into the tree. The larvae overwinter within galleries beneath the bark and resume feeding the following spring. Pupation occurs in early summer, around June, and adult mating flights take place from June through July. When adults emerge, they leave characteristic “D”-shaped exit holes in the bark (Fig. 2; Photograph by Patrick Perish, iNaturalist).
It is not yet known whether A. smaragdifrons will function as a biological control agent for Tree-of-Heaven. Additional research and field observations are needed to determine its impact on its host. However, reports from Beijing Forestry University indicate that attacks by A. smaragdifrons can lead to decline and eventual death of Tree-of-Heaven (Hoebeke et al. 2017).
Scientists with the Indiana Department of Natural Resources and Purdue University are interested in tracking the distribution of A. smaragdifrons across the state. The next time you encounter a Tree-of-Heaven, keep an eye out for the distinctive D-shaped exit holes. In late summer, you may also observe adults feeding on the leaves.

Join Purdue Extension forester Lenny Farlee in this episode of “A Woodland Management Moment” as he discusses the benefits of using windbreak plantings around hardwood tree plantations. Using a black walnut planting as an example, this episode introduces how windbreaks can influence early growth, protection and overall tree form. The video also connects windbreaks to broader planting strategies and long-term management objectives. Watch to learn how thoughtful plantation design can support both tree performance and woodland management goals.
A good resource to learn more is the Walnut Council website. Founded in 1970, the Walnut Council is an international association representing nearly 700 woodland owners, foresters, forest scientists, and wood-producing industry representatives in 45 states and three foreign countries. The purpose is to assist in the technical transfer of forest research to field applications, help build and maintain better markets for wood products and nut crops, and to promote sustainable forest management, conservation, reforestation, and utilization of American black walnut (Juglans nigra) and other high quality fine hardwoods.

Indiana joined 22 other states in 2025 when it launched its state-level Certified Prescribed Burn Manager (CPBM) Program. This program resulted from HB-1557, which went into effect on July 1, 2025. For more information about the new prescribed fire law in Indiana and what it means for burners, check out the Indiana Prescribed Burn Law Factsheet.
This article will walk through the steps to complete all stages of the program. The Indiana DNR CPBM Policy can be viewed by visiting the Indiana Prescribed Fire Council website.
The CPBM program consists of three parts:
Indiana CPBM Requirements At-a-glance
![]()
Online Training Requirements
The online training required for the CPBM program includes many of the same courses as are necessary for Basic Wildland Firefighting.
These are self-paced, free online courses available through FEMA, the National Fire Academy (NFA), and the Wildland Fire Learning Portal.
*Before taking any courses through FEMA or registering for the NFA, you need to obtain a FEMA SID#. You can do that at FEMA: Student Identification System.
![]()
In-Person Training Requirements
The two requirements for in-person training are:
How to complete the in-person training?
In-person S-130 Field Days and Indiana DNR Prescribed Fire for Managers courses are offered 1-2 times per year, often offered in the spring (Feb-Mar) and in December.
*To take the S-130 Field Day, you need to complete the required online training before the field day. To take the Prescribed Fire for Managers Course, you need to take the S-130 Field Day.
You can find information about upcoming trainings by visiting the Indiana Prescribed Fire Council (INPFC) website and the Indiana DNR Fire Headquarters Training Portal.
![]()
Prescribed Burn Experience
To be an Indiana CPBM, you need the following prescribed fire experience:
Serving as an “Apprentice Burn Manager” means you need to lead burns under the guidance of an existing CPBM, RxB1, or RxB2 (RxB1 & RxB2 are Burn Boss qualifications through the National Wildfire Coordinating Group) and complete a Certified Prescribed Burn Manager Task Book related to preparing for and managing a prescribed burn.
To get experience as a crew member on prescribed fires, here are a few steps:
Find Volunteer Opportunities: Many organizations accept volunteers for prescribed fire, but may require Basic Wildland Firefighter Training (see above).
The first step in finding opportunities is building relationships with current prescribed fire practitioners. By volunteering as a crew member, you start to learn about prescribed fire and build relationships with existing burn managers. This may lead to opportunities to apprentice in the future.
The Indiana Prescribed Fire Council is piloting a Prescribed Fire Opportunity Sharing Network to help connect those seeking burn experience with experienced burners. You can use the links below to sign up for this network as either a Mentor (have experience) or Mentee/Apprentice (need experience). Register on the Mentor sign-up or the Mentee sign-up.

Made infamous through the trial of Socrates, Shakespeare’s Hamlet and Macbeth, and several other works of classic literature, poison hemlock is an extremely toxic plant that will pose a risk this summer and should be handled with caution.
Poison hemlock is native to Europe. It is a biennial plant, meaning that it has a two-year lifespan. Last summer, it went through vegetative growth and largely stayed out of sight as a basal rosette. This summer, a long stem (up to 3 to 10 feet tall) will bolt and produce small white clusters of flowers. Poison hemlock is a member of the parsley family and can sometimes be confused with wild carrot. However, its distinguishing feature is its hairless hollow stalks with purple blotches.
The biggest risk with poison hemlock is ingestion. Lethal doses are fairly small, so it is important for animal owners or parents of young children to identify it in their area and remove it if possible. The toxins can also be absorbed through the skin and lungs, so be sure to wear gloves and a mask when handling these plants.
Symptoms of hemlock poisoning include dilation of the pupils, weakening or slowing pulse, blue coloration around the mouth and eventually paralysis of the central nervous system and muscles leading to death. Quick treatment can reverse the effects, so act quickly.
It is considered highly invasive and is listed on both Indiana’s noxious weed list and the terrestrial invasive plant rule list, Indiana General Assembly IC 14-24-12, IC 15-15, IC 15-16-7 to 10, Indiana Department of Natural Resources, Terrestrial Invasive Species – Plants. Thus, its occurrence may have legal implications for landowners. Some Indiana counties aggressively monitor and spray poison hemlock, particularly along county roads. It primarily invades disturbed and early succession sites such as roadsides, stream and ditch banks, vacant lots, and field borders. However, it can spread into pastures, hay fields, and other grassland habitats.
Its sap contains alkaloid toxins which are highly toxic to humans and animals. Although humans would not normally purposely or accidentally ingest poison hemlock (Socrates was a notable exception), care should be taken when mowing or cutting to avoid dermal and respiratory inhalation exposure. Livestock farmers should control poison hemlock in pastures, feed lots and holding pens and ensure it is not baled in hay.
Poison hemlock spreads via seed, so effective management must prevent new seed production, prevent spread of existing seed, and exhaust the existing seed supply in the soil seed bank.
Poison hemlock seed is often inadvertently spread by mowing, road maintenance or agricultural equipment. Mow infested areas along roadsides, ditch banks and field edges before seed develops. A single mowing may delay but not stop poison hemlock from growing another shoot and ultimately flowering and producing seed. Multiple mowings are likely required to prevent new seed production.
Herbicide control should focus on the first-year basal rosette. Herbicide control can still be achieved in the early stages of flower stem development. However, as the flower stem grows so grows the amount of herbicide required to provide full coverage and thus full control. A 2% solution of glyphosate (41% active ingredient) in water with a non-ionic surfactant will provide good control of poison hemlock basal rosettes. If the poison hemlock is growing among desirable grasses, broadleaf-specific herbicides such as triclopyr and 2,4-D are also very effective on poison hemlock and will not harm the grasses. AS always, read the pesticide label for proper, safe handling and use.
For more information see Purdue Cooperative Extension Invasive Plant Fact Sheet Series FNR-437-W, Poison Hemlock. For further guidance on poison hemlock control, contact your county Purdue Cooperative Extension office.
