Controlling Non-Native Invasive Plants in Ohio Forests: Ailanthus
This is yet another activity to add to your fall management and clean up activities: work on eliminating those tree-of-heaven infestations. To understand your options, we have a great resource available here: Controlling Non-Native Invasive Plants in Ohio Forests: Ailanthus
Ailanthus (Ailanthus altissima), also known as tree-of-heaven, is a moderate sized (60 to 80 feet in height), deciduous tree first introduced into the United States from Asia in the late 1700s for use as an urban landscape tree and in strip mine reclamation in the Eastern United States. In many ways ailanthus is an ideal invasive—it grows rapidly (sprouts can attain a height of 6 to 12 feet the first year and grow 3 feet or more per year), is a prolific seeder, a persistent stump and root sprouter, and an aggressive competitor that thrives in full sunlight. It also produces an allelopathic compound that suppresses the growth of many native woody and herbaceous species. It will grow in relatively infertile, shallow soils of varying pH, and is highly tolerant of poor air quality.
Fall Weed Control
The best time of year to manage biennial and perennial weeds is in the fall. Hemp dogbane, ailanthus, poison hemlock are just the tip of the iceberg on the list of weeds effectively controlled now. If you need a refresher, or need to dive in to start learning, here are some resources to get you started in the right direction:

Is it poison ivy?
Poison-ivy (Toxicodendron radicans) is a native, woody perennial vine found all over Ohio and matter of concern for all home and property owners. It spreads by seed, creeping roots and stems that root where the contact the soil. Seeds are also dispersed by birds. Its a fairly common plant for client questions at an Extension Office. As a plant in nature, it prevents very few problems, is a great source of food for songbirds, and provides beautiful fall color. The real problem is when it comes into contact with human skin. All parts of the plant contain resinous compounds called urushiols, which are the oils that cause inflammation of the skin.
