An In-Depth Look at Oak Ivy Plants
Oak ivy, also known as poison oak or poison ivy, is a woody vine plant that can be found growing in many areas across North America. While it may have a beautiful appearance with its bright green leaves during spring and summer, oak ivy is notorious for causing an itchy, irritating, and sometimes painful rash in people who come into contact with it. This rash is called allergic contact dermatitis and is caused by an oil called urushiol that is found within the leaves, stems, and roots of oak ivy plants.
Identifying Oak Ivy Plants
Being able to properly identify oak ivy is crucial to avoid coming into accidental contact with it. There are a few key features to look out for when trying to spot oak ivy:
- Leaves come in clusters of three.
- Leaves have a glossy, waxy appearance.
- Leaves turn bright red and orange in the fall.
- Vine-like growth with aerial rootlets for climbing.
- Berries are yellowish-white to greenish-white in color.
Oak ivy typically grows as a vine or ground cover. It thrives in a variety of environments, including along fence lines, at the edges of forests, in open fields, and in disturbed areas. Be extra diligent when in areas where oak ivy is known to grow to avoid accidental exposure.
Allergic Reaction Symptoms
If exposed to oak ivy, most people will begin to develop symptoms within 12 to 72 hours. The most common symptoms include:
- Red, itchy rash or blisters where exposed skin touched the plant.
- Swelling.
- Burning sensation.
- Dry, oozing spots.
- Difficulty breathing if the reaction is severe.
The rash may continue to worsen for several days after exposure before it peaks and then gradually improves over 1-3 weeks. Avoid scratching, as this can spread the rash and cause an infection.
Treating Oak Ivy Rashes
If you suspect you've come in contact with poison oak or ivy, immediately washing any exposed skin with soap and lukewarm water can help prevent or minimize the allergic reaction. Calamine lotion and hydrocortisone cream can help soothe itchiness and reduce swelling and inflammation.
For more severe reactions, your doctor may prescribe a short course of oral corticosteroids like prednisone to reduce your immune system's response. Antihistamines like diphenhydramine (Benadryl) can also control itching.
Resist the urge to scratch, as this can spread the rash and increase the duration of symptoms. Take lukewarm baths and keep the affected area clean and dry to allow proper healing.
Preventing Oak Ivy Rashes
The most straightforward way to prevent an allergic reaction to oak ivy is to familiarize yourself with what the plant looks like and avoid coming into contact with it in wooded, brushy areas. Wearing long sleeves, pants, and gloves provides a barrier if you are likely to be in an area where oak ivy may grow.
There are also preventative products available that can be applied to the skin before exposure. These include products containing bentoquatam, Tecnu, and other topical creams that create a barrier and bind to the urushiol oil before it can penetrate your skin.
Finally, washing your gardening tools, hiking gear, and clothing after potential oak ivy exposure can help prevent residual oils from causing a rash later on. Urushiol oil can remain active on surfaces for up to 5 years.
Getting Rid of Oak Ivy from Your Property
If you find oak ivy growing on your property, getting rid of it quickly and safely is important to prevent painful rashes. Here are some tips for effective oak ivy removal and eradication.
Manual Removal
Manual removal involves digging up oak ivy plants at the roots or pulling them out. This is most effective for small infestations. Be sure to wear gloves, long sleeves and pants to prevent skin exposure when doing this.
Use a spade or trowel to dig under the root system and remove the entire plant. Double bag any plant parts and discarded gloves afterwards to prevent accidental exposure from residual oils.
For climbing vines, cut the vine near the ground first before pulling down. Focus on removing the roots and lower parts of the vine to prevent regrowth.
Goat Grazing
Goats are able to digest oak ivy without issue, making goat grazing an eco-friendly option for larger infestations. The goats will eat the above-ground parts of the plants. Pair grazing with root removal for complete eradication.
Chemical Herbicides
Chemical herbicides containing glyphosate or triclopyr can be effective sprays for killing oak ivy. Carefully follow directions and only use herbicides approved for your particular location.
Avoid drift onto desired plants. It may take several applications spaced weeks apart to fully kill established oak ivy.
Smothering
Smothering involves covering oak ivy with mulch or landscape fabric to block its access to sunlight. Over time, this will kill the plants. Leave the barrier in place for at least a full growing season.
Combine with root removal for best results. Be sure your barrier material fully overlaps the edges of the infestation to prevent regrowth.
Professional Removal
For severe oak ivy problems, bringing in professional weed removal services may be warranted. Companies can apply high-strength herbicides and use tools you may not have access to.
They also have the proper protective gear to remove plants safely. This is a good option for large-scale infestations like on industrial or municipal properties.
Protecting Yourself During Removal
If tackling oak ivy removal yourself, be sure to take protective measures:
- Wear gloves, long sleeves and pants with no gaps.
- Seal gloves to sleeves and pants with duct tape.
- Cover as much skin as possible.
- Wear eye protection.
- Place removed plants in heavy duty bags.
- Wash all clothing and exposed gear after.
Carefully monitor the area and promptly remove any regrowth. Eliminating this hazard from your property reduces the risk of painful rashes from accidental exposure.
