In Western Maryland the foliage season is coming to a close, while trees on the Eastern Shore are hitting a midpoint. Trees in Central Maryland are at peak.
“In Anne Arundel, the sun-splashed yellow hickory leaves are sprinkled through the forest canopy. The red black gum are prominent while sweet gum are reddening up,” says Francis Smith of the Maryland Forest Service.
“In the Hagerstown watershed forest, the sugar maple, sweet birch, and tulip poplar are positively glowing with the fine weather we’ve had,” Forester Bob Schwartz reports. “These less developed areas with more extensive shallow groundwater flow seem to be avoiding the lackluster color predicted due to the drought this summer.”
The pine trees on Assateague Island are evergreen, but Assistant Park Manager Meghan Rhode said fall color makes its presence known, “Whether it is the orange of the monarch butterfly, the bright yellow of the goldenrod or red-brown coats of the Assateague ponies.”

This will likely be my last report from Garrett County for the year as things continue to wind down and the sun begins to set on our foliage season. The oaks are putting on the final show with golden to burgundy tones. If you’re wanting to see fall foliage in Garrett County – do it soon before it’s gone! With continued warm and dry weather in the forecast I don’t expect the remaining color to last much past the end of October this year.

We are still experiencing severe to extreme drought throughout the county as evidenced by low water levels in many bodies of water. As we continue through fall, fire danger is likely to increase with warm, dry weather in the forecast and dry leaves accumulating on the forest floor. Be mindful of and adhere to state and local burning regulations. Find more information about state outdoor fire regulations on the Maryland Forest Service website.

Aaron Cook, Forester for Maryland Forest Service, Washington County
Peak fall color has not been uniform across Washington County this fall. This is not unusual, as elevation, aspect, forest species composition, and other environmental factors all influence this annual change. Some areas of the county are at or will soon be at peak color, these include the ridges in the western part of the county and South Mountain in the north. The lower elevations of these same ridges along the Potomac River are a little further behind, but may be at peak color by this weekend, and our oaks are still just beginning to change color, although they are not known for the vibrant reds and yellows that our other forest trees produce.

At a landscape level, the oaks are usually bronze or brown. If you get into the forest on a hike, individual oaks can be rather spectacular, albeit a branch at a time with shades of burgundy, purple, red, and bronze. Oak leaves quickly turn brown, and the leaves tend to hang onto the trees for most of the winter. This phenomenon is known as marcescence, which is not a fully understood evolutionary trait. Regardless, these leaves persist as a treat to the eyes and ears on breezy winter days and are often complimented by accompanying shrubs with persistent winter fruit and evergreens.
Speaking of evergreens, I have noticed that eastern white pine is yellowing in an attempt to join in on the frenzy of fall colors. Our office often receives calls about dying white pines from concerned landowners each fall, but this is a natural occurrence in the fall as old needles are shed by the tree.
Foresters often prescribe the “shelterwood treatment,” which regenerates sun-preferring species under the temporary shelter of an open overstory, to perpetuate oak-dominated forest ecosystems; it can also be employed to regenerate white pine forests.
While oaks are not always associated with magnificent fall colors, they are a keystone species that play a critical role in our ecosystem by providing food and habitat for a wide variety of organisms, without oaks the ecosystem would be significantly impacted. If the weather continues to hold, this should be another fine weekend to get out and enjoy the peak of fall color.
Bob Schwartz, Watershed Forester for Maryland Forest Service in Washington and Frederick counties
We’re certainly at peak color along South Mountain in Washington and Frederick counties, although the Hagerstown Valley lags behind. In the Hagerstown watershed forest, the sugar maple, sweet birch, and tulip poplar are positively glowing with the fine weather we’ve had. These less developed areas with more extensive shallow groundwater flow seem to be avoiding the lackluster color predicted due to the drought this summer.

Nearby, blue wood aster is in full bloom. This lovely sky-blue aster lives in part-shade and features one of the latest bloom periods, a boon for late-season pollinators provisioning their young for next spring. With its compact form, this is a wonderful aster for both the woods and home landscapes.
Meanwhile, Red Oak is living up to its name, providing flame red hues to the golden tones of the other hardwoods. The oak genus, Quercus, has been shown to support the most insect species, over 500, of any group of trees in Eastern North America. White and red oaks are truly the powerhouses of our forests for everyone: insects, the birds they feed, and larger wildlife, as well, while giving humans quite a show come autumn. From the diminutive Bear Oak to a full-sized White Oak, there is an oak for every situation so you too can bring this piece of nature, and all its associations, home.

This week is showing peak colors all across the mountain, at all elevations! Colors are vibrant and beautiful!

In Anne Arundel, the sun-splashed yellow hickory leaves are sprinkled through the forest canopy. The red black gum are prominent while sweet gum are reddening up. Below the multi color mosaic of an overstory, the dogwoods are getting an even deeper wine red.

Meghan Rhode, Assistant Park Manager for Assateague State Park
While the lower Eastern Shore has been seeing a change in tree color for at least a week or two now, the trees that surround Assateague Island just recently got the message to start the show. The corridor that welcomes you to the island is displaying a variety of bold fall colors! Assateague State Park consists mainly of loblolly pines and low shrubs that do not give that fall feeling but we notice fall in other ways, whether it is the orange of the monarch butterfly, the bright yellow of the goldenrod or red-brown coats of the Assateague horses. The island has a unique and beautiful way of welcoming in the cooler temperatures and shorter days of fall!

We could have a Halloween Comet. It all depends on if it breaks up before it gets to us. Early on Oct. 24 if you looked east just after sunrise you may have seen it as it zipped by Earth. C/2024 S1 has to survive its trip around the sun. It will be 900,000 miles away at its closest, as it slingshots back towards Earth. If it stays intact, it will reappear in the western night sky around Halloween and depending on what’s left, you could see it into December.
On October 25, look east for the Andromeda Galaxy. You should still be able to see it without a telescope on Friday night, even though it’s 2.5 million light years away. To give you an idea how far that is, it would take 12 million years to travel one light year traveling at 56 mph. The Andromeda Galaxy is our galactic neighbor. It is 200,000 light years in diameter and has roughly one trillion stars. By comparison, our own Milky Way is half that size.
The moon is waning, so stargazing will be better the rest of the month. Enjoy the warmer evenings while you can.
