10 Trees with Amazing Fall Color... and One You Should Avoid!
I was recently pruning trees in a newer neighborhood on the east side of Columbus where every house had two red maple in the front yard. Although Red maple is a native tree to Ohio, this subdivision was planted with a cultivated variety of the species called ‘Red Sunset.’ ‘Red Sunset’ red maple was selected and well marketed for its compact habit, good branching structure and most notably for its showy and reliable orange to red fall color.

I was recently pruning trees in a newer neighborhood on the east side of Columbus where every house had two red maple in the front yard. Although Red maple is a native tree to Ohio, this subdivision was planted with a cultivated variety of the species called ‘Red Sunset.’ ‘Red Sunset’ red maple was selected and well marketed for its compact habit, good branching structure and most notably for its showy and reliable orange to red fall color.
Unfortunately for most of us in the central Ohio area, ‘Red Sunset’ Red maple was selected in Oregon and requires an acid soil with consistent moisture to perform well. It does not like the dry and often high pH soils of our urban landscapes.
The trees I observed on the East side of town had just been planted in the last 12-15 years, were in poor health & vigor and were already expressing advanced symptoms of chlorosis, a nutrition deficiency that causes yellowing, stunted growth, decline and eventual plant death.
Chlorosis in a Red Maple
I learned about chlorosis in different Red maple cultivars (short for cultivated varieties) when I was a horticulture student at OSU and I still deal with it daily in my career as an arborist. I see chlorotic Red maple in parks, commercial buildings, along streets and in private gardens every day. I even see chlorotic red maple in the aisles of reputable nurseries.
How has this tree become so popular? I believe it’s because it has been so well marketed. Maple has name recognition amongst most folks and the nursery industry loves red maple because it is easy to propagate, and they can produce a sellable tree from small whip in a short amount of time.
When I have the opportunity to ask clients why they selected this tree for their landscape I generally get one the following responses.
Somewhat common: Name recognition, they admit they don’t know much about trees, but they remember maple being a good tree from their childhood.
More common: Their landscaper recommended it (interesting side note: I have yet to hear from anyone that their arborist recommended it).
Most common: They were looking for something with nice fall color.
I’m a sucker for some nice fall color also and I’m here to report there are a lot of other great alternatives to red maple when looking for trees with nice fall foliage. The following are some of my favorite fall color trees that are adaptable, urban tolerant, and easy to grow.
Valley Forge American Elm
Great fast-growing historic shade tree adaptable to most soil types – reliable yellow to gold fall color.
Japanese Zelkova
Another urban tolerant medium to fast growing shade tree with nice vase shaped canopy with yellow to apricot to red fall color.
Black Tupelo
Excellent tree for glossy red fall color. Some cultivars will color yellow and red. Slow growing medium sized tree.
Hickory
This image is of a Pignut hickory but most species of hickory color beautifully in the fall. Slow growing tree. Plant this one for the next generation. Great tree for wildlife.
Sassafrass
Medium sized fast-growing tree in youth. Great yellow to orange to red to purple fall color – can be variable from year to year. One of Ohio’s most outstanding native trees for fall foliage.
Witch Hazel
There are dozens of cultivars of witch-hazel. Most of them have showy fall color. This image is the fall foliage of ‘Diane’ witch-hazel, one of my favorites. Also has showy red flowers in late winter.
Kousa dogwood
Great ornamental tree with exceptional yellow to red fall color. Also has great flowering show, beautiful bark at maturity and interesting fruit.
Ginkgo
Unrivaled for golden yellow fall color. My only complaint is that the show is short lived, often only 2 – 3 days.
Dawn Redwood
Foliage turns an excellent copper orange to brown before leaf drop. Fast growing, significant pest and disease-free shade tree.
Japanese Katsura
Medium to fast growing shade tree. Fall color can be apricot to scarlet red. Fall leaves smell like cotton candy.

Fall Webworm In Full Effect

Fall Webworm vs. Bagworm
We’ve received a high volume of calls over the last couple of weeks about “bagworms” in client’s trees. In central Ohio, true bagworm feeds predominantly on evergreens - arborvitae, spruce, and junipers although some deciduous trees can be hosts as well. Generally, this feeding occurs late Spring through mid-Summer and by mid-August they have stopped feeding to go pupate and become a moth. So I initially was confused about this late population of “bagworm” that had taken central Ohio by surprise and was making my appointment schedule grow faster than kudzu.
After visiting with a few customers, I realized the real culprit of concern was actually, Fall Webworm - not Bagworm. It’s easy to understand why a lot of folks call this pest (which resembles a bunch of worms in a bag) bagworm. This article should clear this up. (For information on true bagworm see the postscript at the end of this post). For those of you reading this article, I hope you can help me to rise up and start a movement to correct this awful error in nomenclature. 😉
The Facts about Fall Webworm
Fall webworm on Bald cypress
Fall webworm is a native pest of shade trees and ornamentals and can appear early summer through early fall. It feeds on over 100 different species of trees commonly attacking hickory, walnut, elm, birch, cherry, and willow. In urban landscapes, I’ve observed it daily on oak, sweetgum, redbud, linden, mulberry, and crabapple.
Fall webworm gets most folks attention by the large unattractive webbed nests it makes at the ends of branches. In most cases, Fall webworm is most damaging to plants aesthetically, diminishing the beauty of its host plant. A large nest can contain dozens to hundreds of caterpillars and can measure up to 3 feet across. Even after caterpillars have left to pupate, empty webbed nests can persist for months containing dried up leaf fragments and lots of caterpillar feces.
A fall webworm feed generally lasts for 5 - 6 weeks before the caterpillar leaves its host plant to pupate in the soil. Fall webworm generally has 2 generations per year.
Fall Webworm Management
Because Fall webworm generally causes little to no harm to the overall health of established healthy trees, I generally do not recommend management for this pest. Ohio has dozens of natural predators that make a living on Fall webworm including several species of birds, parasitic wasps, and other beneficial insects and they can generally keep populations of Fall webworm in check without the help of human intervention.
Newly planted trees could be at risk of significant defoliation and heavy feeding could impact fruit or nut yield for crop trees. If management of Fall webworm does become necessary, nests can be pruned out and destroyed or insecticides can be sprayed to kill the caterpillars while they are feeding. The beneficial bacteria "Bt" (Bacillus thurngiensis) can also be used on young caterpillars. This is available at most high-end garden centers labeled as Dipel or Thuricide.
If spraying is your control method of choice, please note that product only needs to be applied directly to the nests (rather than the entire tree) to avoid damage to beneficial insects and other non-target organisms.

And Now, Bagworms
Bagworm is a small caterpillar that uses silk and bits of foliage and bark from its host plant to make a small bag around its body to protect itself. Each bagworm has its own individual bag (which often resembles a small pine cone), rather than large webbed nests that protect entire communities of caterpillars like in the case of Fall webworm. Bagworms feed aggressively from late May through July and can quickly defoliate entire portions of trees and shrubs if left unchecked.
Bagworms can be removed from plants by hand and disposed of easily on small trees and shrubs. On larger plants, insecticide applications can be made effectively through June before bagworms have covered their bodies with their bag.

Arborist Thoughts
- tree of great historical significance, American Elm once lined the streets of the Midwest and New England before the accidental introduction of Dutch Elm Disease. Much breeding and selection work has been done to develop Dutch Elm Disease resistant cultivated varieties and reintroduce the American Elm into our landscapes and streets. ‘Valley Forge’ is reported to have the highest tolerance to the Dutch Elm disease. Other resistant cultivars to consider are ‘Princeton’ and ‘Jefferson.’
American Elm is an urban tolerant, adaptable, easy to grow tree with nice fall color. If you are looking for a fast-growing shade tree for your landscape, this is one to consider.
