Several things come into play when it comes to determining the colors that we find on leaves of our trees. As our days get shorter and our nights get longer there is a chemical change that happens in the tree. In this video Lenny Farlee talks about the several pigments that are found in trees and what changes from summer to fall that brings us the bright colors on leaves.

Hunting Safety Tips and Reminders
Indiana DNR reminds you to stay safe this deer season. Hunting injuries most commonly involve elevated platforms and tree stands, so stay safe by following the guidelines below.

Tree stand safety before the hunt:

• Read, understand, and follow the tree stand manufacturer’s instructions.
• Check tree stands and equipment for wear, fatigue, rust, and cracks or loose nuts/bolts, paying particularly close attention to parts made of material other than metal.
• Practice at ground level with a responsible adult. If you need to sight in your equipment, find a shooting range near you.
• Learn how to properly wear your full-body safety harness.
• Make a hunt plan and share it with someone before your hunt.
• Wear your full-body safety harness.
• Use a tree stand safety rope.
• Make certain to attach your harness to the tree or tree stand safety rope before leaving the ground and check that it remains attached to the tree or tree stand safety rope until you return to the ground.
• Maintain three points of contact during ascent and descent.
• Wear boots with nonslip soles.
• Use a haul line to raise and lower firearms, bows, and other hunting gear.
• Make sure firearms are unloaded, action is open, and safety is on before attaching them to the haul line.

General reminders:

• Hunter Orange – know when to wear it and how much is needed on a ground blind
  • Hunter orange is required for all deer hunters during youth, firearms, and muzzleloader season. Hunter orange must be worn at all times during the hunt, including walking to and from the hunting location. Regardless of hunting equipment being used (archery, crossbow or firearm), if it is firearms season, you are required to wear hunter orange.
  • A ground blind must have at least 144 square inches of hunter orange material that is visible from any direction during any season in which a hunter is already required to wear hunter orange.
• Firearm Safety – Treat every firearm as if it is loaded, keep the muzzle pointed in a safe direction, keep your finger off the trigger until you are ready to shoot, and be sure of your target and what is beyond it.
• Print and complete a Landowner Permission Form if hunting on private land that isn’t your own.
• Remember to complete and attach a deer transportation tag immediately upon taking a deer. The tag should be attached to the deer during transportation and any time the deer is unattended.

Always bring emergency equipment with you on your hunt, such as a cellphone, flashlight, small first aid kit and extra water.

Many people in the Midwest know about and admire flowering dogwood trees and their distinctive spring flowers, which display conspicuous white or pink bracts (flower structures that resemble petals). Reportedly, George Washington and Thomas Jefferson were fans of this tree as well, planting them at their homes in Mount Vernon and Monticello, respectively. Did you know that we have nine native dogwood species in the Midwest?

I’m sourcing information from two books written by Purdue University experts, Native Trees of the Midwest and Shrubs and Woody Vines of Indiana and the Midwest.

All but one of our native dogwoods (Cornus spp.) have an opposite leaf arrangement, and the leaves look similar, with veins that form an arc that follows the leaf’s shape toward the tip. This characteristic is known as arcuate venation. Fruit can vary among species, exhibiting hues of red, white, or blue. Fall leaf color usually ends in a deep red color. Although I won’t cover pith color (the center of the stem) in detail here, pith color of first- and second-year twigs is usually another good tool for identification. Most species have red or green twigs that add winter interest.

Homeowners may concentrate on the traditional flowering dogwood (C. florida) tree. It is a small tree, usually not exceeding 30-40 feet in height. It is moderately shade-tolerant and may struggle in full sun in home landscapes. In natural areas, it is typically found mixed with hardwoods and conifers in open woods and woods’ edges in rich, well-drained soils.

In addition to the flowering dogwood tree, other native dogwoods are considered shrubs.

Pagoda dogwood (C. alternifolia) is a small tree-sized shrub reaching heights of 18 to 20 feet. Its layered branching with upswept branch ends on older specimens resembles the roof of a Japanese pagoda. This shrub is also known as alternate-leaf dogwood; it is the only native dogwood with an alternate leaf arrangement. Fall leaf color features multiple hues and usually ends in deep burgundy. It is a beautiful and popular choice in home landscapes.

Bunchberry or dwarf cornel (C. canadensis) is the smallest of the native dogwoods. At a maximum height of 8 inches, it is classified as a sub-shrub. It is more common in northern states because it is unable to survive in soil temperatures greater than 65 degrees. Underground rhizomes allow large colonies of this plant to form.

Swamp dogwood (a.k.a. southern swamp dogwood, stiff dogwood; C. foemina or C. stricta) is found mainly in southern Indiana counties in poorly drained woodlands. It can grow to 9 feet in forest understories.

Rough leaf dogwood (C. drummondii or C. asperifolia) is one of our largest native shrubby dogwoods, growing to 12-15 feet or more. As the name suggests, leaves are rough with hairs on the underside. This shrub is easy to grow, but it needs room to grow. Suckers will give rise to new plants but can be controlled with mowing. First-year twigs are reddish-brown with flattened hairs, turning gray and hairless the second year.

Silky dogwood or pale dogwood (C. obliqua or C. amomum) has reddish twigs and a brown pith. The bark is reddish gray with vertical light brown shallow fissures, unique to this dogwood. In nature, this shrub is found along ponds, lakes, streams, and swamps, so it is usually associated with water. It is relatively easy to grow and is commonly found in nurseries.

Gray dogwood or northern swamp dogwood (C. racemosa) only gets about 4-5 feet tall. It frequently forms dense clonal communities that offer cover to wildlife. It can be found in nurseries that specialize in native plants. It is adaptable to wet or dry locations.

Round-leaf dogwood (C. rugosa) is a 5-6 feet tall shrub, more commonly found in the northern tier of Indiana counties. It has pinkish-green, purple, or yellow twigs that become rough with age. As the name suggests, its leaves are broadly ovate (rounder) than those of other shrub dogwoods and may resemble the leaves of flowering dogwood trees. Root suckering can produce small clumps that become small thickets over time.

Red-osier dogwood (a.k.a. red twig dogwood or American dogwood; C. sericea or C. stolonifera) is especially adaptable and the most widely available native shrub dogwood in midwestern nurseries. Its wine-red twigs (when young) are a landscape feature that stands out in winter. Bark on older specimens turns from red to greenish and eventually to grayish-brown. At up to 9 feet tall, it is one of the larger dogwoods, and it’s easy to grow and maintain. In natural areas, it is found in wet, boggy places and is a sun-loving shrub that will tolerate some shade.
You may also come across other non-native dogwoods available in nurseries, such as kousa dogwood (C. kousa), Tatarian dogwood (C. alba), or cornelian cherry dogwood (C. mas).

Identifying dogwoods (especially the shrubs) can be difficult, partly because all the leaves look similar. Finding a good field guide or identification book will help. Some plant identification apps may do a decent job but may need to be double-checked by a good reference book. Find additional information at the Purdue Arboretum.

Purdue Landscape Report: Fall is one of my favorite times of year. The temperatures begin to cool, the humidity drops, and the landscape starts its annual transformation as trees trade their summer greens for shades of yellow, orange, and red. For those of us who enjoy spending time outdoors, it can also be one of the most pleasant times of year to work in the landscape.

As fall approaches, one question I frequently hear is:
“Is fall a good time to plant a tree?” The answer is yes!

In fact, fall can be an excellent time to add a new tree to your landscape. Cooler temperatures and decreased drought stress can make the transition from nursery to landscape less stressful for newly planted trees. As long as you select an appropriate tree, plant it correctly, and provide proper care after planting, a fall planting can give a tree an excellent start.

Why plant trees in the fall?
One of the biggest advantages of fall planting is the weather. Compared with the heat of summer, cooler fall temperatures reduce heat stress and typically lower evapotranspiration—the amount of water lost from plants and soil to the atmosphere.

Fall also shifts the tree’s priorities. Rather than putting most of its energy into producing new shoots and leaves, a deciduous tree is preparing for dormancy and continuing to develop its root system. Planting during this period can allow roots to become established before the tree has to deal with the heat and water demands of the following summer.

Of course, cooler temperatures and fall rainfall do not eliminate the need to water a newly planted tree. Newly installed trees still require regular attention while their root systems become established.

What should I consider when planting in the fall?
There are a few important considerations to keep in mind.

• Water is still important. If rainfall isn’t providing approximately 1 inch of water per week, newly planted trees will need supplemental irrigation. A useful general guideline is approximately 5 gallons of water per week for every inch of trunk diameter, although actual watering needs will vary depending on soil, weather, tree size, and site conditions. Rather than relying solely on a calendar, check the soil and adjust watering based on conditions.
• Don’t forget to mulch. Apply a layer of organic mulch over the root zone to help conserve soil moisture and moderate soil temperatures. Keep mulch away from direct contact with the trunk—avoid creating the familiar “mulch volcano” around the base of the tree.
• Give the tree time to establish. Ideally, trees should be planted early enough in the fall to allow their roots to become established before the ground freezes. A common recommendation is to allow approximately six weeks between planting and the first hard freeze.
• Choose the right tree for the site. Fall is a good planting season, but it doesn’t make a poorly matched tree a good choice.
• Consider the mature size of the tree, available growing space, soil conditions, sunlight, drainage, and other site characteristics before making your selection.Think about winter protection. Some trees, particularly broadleaf evergreens, may be more susceptible to winter injury because they continue to lose moisture through their leaves when the ground is frozen and roots cannot readily replace that water. Newly planted trees may also benefit from protection against trunk damage from wildlife or winter sun exposure, depending on the species and site.

Give your tree a good start
Planting a tree is a long-term investment. The work you put into selecting, planting, watering, and caring for a tree during its first few years can have a significant impact on its future health and structure.

So, if you’ve been waiting for cooler weather to add a tree to your landscape, fall can be a great time to get planting. Choose the right tree for the right place, plant it properly, and don’t forget about it once the leaves have fallen.

If you have questions about selecting, planting, or caring for a tree, contact your local Extension office or consult an ISA Certified Arborist for site-specific advice. You can find an ISA Certified Arborist through Find an Arborist.

Ecologically, Indiana is truly the Crossroads of America. From towering sand dunes and expansive prairies in the north, to rolling forests and verdant swamps in the south, this state is an intersection of ecosystems, with a rich diversity of native flora and fauna. And throughout the state’s history, this array of natural areas regularly experienced fire.

Human-Caused Fire in Indiana
Intentional fire was part of Indiana’s natural world for millennia as native people used it to steward the land. The land itself tells the story through burn scars and charcoal buried deep in sediment, and the tale is echoed by fire’s cultural importance. In the Myaamia lunar calendar, the transition from summer to fall is known as šaašaakayolia kiilhswa, Grass Burning Moon, followed by kiiyolia kiilhswa, Smokey Burning Moon. It is clear Indiana’s natural places are no strangers to fire.

How Human-Caused Fire Shaped Indiana
Over millennia of human stewardship, fire became an integral part of life for Indiana’s plants and animals, as evidenced by the strong and varied relationships they still have with it. Oaks with thick, protective bark and flammable leaves dominate the woodlands, while Jack pines thrive in the dunes, their cones opening to release their seed after experiencing intense heat. On the prairies and savannas, smoke exposure enhances germination in wildflowers like purple coneflower and savanna blazingstar. Bison and elk, attracted to the nutritious new grass that followed a burn, once roamed the grasslands and forests. These are only a few examples of the ways Indiana’s natural world was (and is) intertwined with fire.
Without fire, many ecosystems that define Indiana’s wild places wouldn’t exist at all. After all, what is a prairie without little bluestem, or an oak woodland without oaks?

Burning for Benefits: The Past and Today
Fire and the changes it caused provided many benefits for Native American stewards. Plants the fires encouraged were used for food and medicine, and hunting opportunities abounded as game animals sought out burned areas. Open landscapes made defense and movement easier. Native Americans needed a healthy, biodiverse natural world to thrive, and intentional fire was an important means of achieving that goal.
Today, healthy ecosystems are still key to the well-being of humans and wildlife alike, providing us with clean water, air, food, and more. And while fire suppression took hold for decades in the 20th century, land managers are beginning to bring this vital force back to Indiana. When fire is reintroduced thoughtfully to the landscape, it can provide many of the benefits it did for thousands of years, allowing Indiana’s natural places and its people to thrive.
In this series, Burning for Benefits, we will dig into the specific ways fire benefits everything from birds to blooms to human health. By looking at each individual impact, we build a picture of how fire belonged in Indiana and can belong here again.

Purdue Landscape Report: This article is not meant to raise an alarm for a new, deadly tree disease. Rather, I wish to increase your awareness of a disease that has been around for a long time. According to Purdue experts, it is one of the most common and destructive diseases of woody ornamental plants in the Midwest.

John Bonkowski, plant disease diagnostician, and Tom Cresswell, director of the Purdue Plant and Pest Diagnostic Laboratory (PPDL), authored the Purdue Extension publication entitled “Verticillium Wilt of Woody Plants.”

The authors describe common and highly susceptible woody hosts of this disease, including redbud, smoketree, tree-of-heaven, maples, rose, lilac, boxwood, and barberry. In addition to woody plants, Verticillium also infects potato, tomato, pepper, eggplant, raspberry, and peppermint. More than 300 plant species have been reported to be susceptible to the disease.

Verticillium wilt is caused by soil-borne fungi in the genus Verticillium. V. dahliae is the most common pathogen encountered in the Midwest, according to the experts. The fungus lives in the soil, and fungal hyphae (microscopic, thread-like filaments that make up the “vegetative” body of fungi) infect plants through the root system of susceptible hosts and invade their water-conducting tissues (xylem). The tree responds by plugging some of the water-conducting vessels with gums and other materials. This restricts water flow in the plant, leading to drought-like symptoms and dieback.

“During midsummer, leaves turn yellow at the margins, then brown and dry,” they said. “Sudden wilting of leaves on one or several branches may occur, which is known as flagging.” They said that frequently, the foliage on only one side of a tree wilts, while the other side remains healthy. The wood under the bark of wilting branches is discolored in streaks following the length of the stem. “The discoloration will vary from bright olive-green (maples) to chocolate-brown (redbud), depending upon the tree species and how long it has been infected.”

“To examine for discolored sapwood, cut into the outer sapwood at the base of branches showing leaf wilt; also examine the outer rings of wood at the cut end of a pruned branch for discoloration,” they said.

“Host susceptibility, site conditions, and environmental conditions influence severity of symptom development,” they said. “Trees under drought, nutrient, or salt stress are more symptomatic.” They said that the speed of decline due to Verticillium wilt will also depend on the tree species. An infected tree may die in a single season or linger on for many seasons, with branch after branch dying and later being invaded by other decay or canker fungi.

So, what can a homeowner do?

“There are no effective fungicide treatments for infected trees,” they said. “Trees or shrubs with mild symptoms can often be maintained for several years by pruning out dead limbs and providing optimal care (appropriate amounts of mulch and fertilizer, and irrigation during dry periods).” Ultimately, most susceptible woody plants decline and die within a few years following first appearance of symptoms.

They said that only Verticillium-resistant trees and shrubs should be planted in landscape sites known to have Verticillium in the soil.

Although Verticillium wilt could affect trees virtually anywhere in Indiana, it is not present in every landscape. In fact, Cresswell said, “We find Verticillium only a few times a year, and it is probably widely scattered all over the state.” So, don’t be too quick to give up on your trees and shrubs, nor immediately assume that a declining tree, such as a maple, has Verticillium wilt.

If you suspect that a plant in your landscape might be suffering from Verticillium wilt, you can send a representative sample and a completed submission form to the Purdue Plant and Pest Diagnostic Laboratory for analysis. Stems should have streaks in the wood to test for Verticillium. Find information at the Plant & Pest Diagnostic Lab.

Find a more complete listing of susceptible and resistant plants in the referenced publication, available at Purdue Extension’s Education Store.

As the crisp autumn air settles in and campfires become a seasonal staple, October brings an important reminder: your firewood choices matter. That’s why October is officially Firewood Month, a nationwide campaign to raise awareness about the risks of moving firewood and the spread of invasive forest pests.

Why “Don’t Move Firewood” Matters
Transporting firewood, even just a few miles, can unintentionally spread destructive pests like emerald ash borer, Asian longhorned beetle and spongy moth. These invaders often hide inside or on firewood, threatening Indiana’s forests, parks and urban trees.

The Don’t Move Firewood website offers excellent resources to help you make informed choices. Whether you’re heating a cabin, heading out to hunt, or planning a backyard bonfire, they recommend:

• Buying firewood where you’ll burn it
• Choosing certified heat-treated wood
• Gathering wood on-site when permitted

You can also explore their Firewood Month Toolkit, maps of regulations and a webinar series designed for professionals and outdoor enthusiasts alike.

While October is Firewood Month, the risk of spreading invasive pests lasts well beyond the fall. Many forest pests remain a threat throughout the year. Adults may still be visible until the first hard freeze, and egg masses can be observed from now through June. The spotted lanternfly females lay egg masses in late summer through early winter, often peaking in October. These masses can survive through winter and hatch in the spring. Learn more about the Spotted Lanternfly from the Indiana Department of Natural Resources. This is why it’s important to practice safe firewood habits year-round.
