Cindy,
I just got back from a lecture by Rudy Mancke from "Nature Scene" on PBS .
He said "If it has leaves of 3 let it be" Count your leaves, if it has 5 it
could be virginia creeper, which , is not poisionous.

Poison oak is in the same family as poison ivy and is similar in
appearance. If you have oily-looking oak-like leaves arranged in
threes, you've most likely got poison oak. I'd get rid of it the same
way you get rid of poison ivy. Whether or not you want to bother
depends on where it is, exactly. If it's in brush that people don't
usually travel through, I'd leave it alone. If it's sprouting by itself
next to the house and looking like a weed, I'd get rid of it. If it's
coming up in a bed, I'd definitely get rid of it like any old weed.
BTW, _don't_ burn the refuse if you do take it out! The toxins are in
the oils, which are volatile and will be all through the smoke from it,
just like poison ivy. I don't even want to _think_ about having poison
ivy internally!

I doubt very much if you've got poison oak in Georgia, as it's native
to the western states. Try doing an "advanced" search on
http://www.hotbot.com with the "image" box clicked, and look for poison
ivy or poison oak for pictures.
As to control, glyphosate (Roundup and similar products) work well
if you follow instructions precisely. Check the directions at
http://www.roundup.com
Here's an old post of mine from rec.gardens on identifying
poison ivy, poison sumac, and poison oak.
-------------------
POISON IVY (Toxicodendron radicans = Rhus radicans = Rhus toxicodendron)
Found in a wide range of habitats, but in the midwest often seen in
disturbed woods, roadsides, and flood plains. Most widespread of PI, PS,
and PO. Small, slightly woody plant, or shrubby, or vining. LEAVES
ALTERNATE (= 1 leaf per node), TRIFOLIATE (= 3 leaflets), with pedicel
(leafstalk) and the CENTRAL LEAFLET WITH PETIOLULE (= leaflet stalk). The
lateral two leaflets are not distinctly stalked. Leaflets are a variety of
shapes, but generally ovate or obovate (roughly apple-leaf shaped).
Leaflets may be smooth-edged (entire), irregularly toothed, or shallowly
lobed. Leaves of one variant look like small oak-leaves (but look again!).
Leaves apple-green and shiny in the spring, deep green and often dusty in
the summer, turning a glorious reddish orange in the fall. Flowers tiny,
whitish, in clusters; fruits white berries in late summer or fall.
Closest look-alike: Box-elder seedlings (Acer negundo), which has
OPPOSITE, trifoliate leaves; the lateral two leaflets are often slightly
stalked. Older box-elders generally have 5 leaflets per leaf.
-----------------
POISON SUMAC (Toxicodendron vernix = Rhus vernix)
Shrub, to perhaps 15-20 ft tall, often branched from the base. LEAVES
ALTERNATE WITH 7-13 LEAFLETS, lateral leaflets without a petiolule
(leaflet stalk), TERMINAL LEAFLET WITH A STALK. MIDRIB OF THE LEAF WITHOUT
A PAIR OF WINGS OF TISSUE THAT RUN BETWEEN LEAFLET PAIRS. More small,
whitish berries in a long cluster. Usually in wetlands, Maine to
Minnesota, south to Texas and Florida.
Closest look-alikes: Staghorn sumac, Rhus typhina, which has clusters of
fuzzy, red fruits and toothed leaflets, and likes dry soils; Smooth sumac,
Rhus glabra, with bright red fruits and slightly toothed leaves; much
drier soil than PS.
-------------------
POISON OAK (Toxicodendron diversiloba = Rhus diversiloba=Toxicodendron
quercifolia)
Reputedly the worst of the bunch. Western states, though there's a lobed
form of poison ivy in the east often confused with poison oak. Erect
shrub, usually about 3-6 ft tall (to 12 ft!), bushy, with ALTERNATE LEAVES
OF THREE LEAFLETS, the LEAFLETS generally lobed slightly or as much as an
oak leaf; CENTRAL LEAFLET STALKED. Leaves generally bright, shiny green
above, paler below. Fruits are small whitish berries. Common on the west
coast, esp. low places, thickets and wooded slopes. Occasionally a
5-leafleted form is found.

Good for you. In case you missed it there was another post that said the
smoke when inhaled would be just as bad only inside the lungs.

Subject: Re: poison oak
Bunny, I've tried AND tried AND tried vinegar on a particularly bad bunch
of it and while it killed the foliage, the vine kept coming back. The only
solution I've found is getting a rake, winding the ivy around the rake, and
then pulling. Use a stick to pull it off the rake. We dispose of it by
tossing it WAY out in the forest in an inaccessible part. We wash the rake
with a hose and detergent. THEN, I used that area to burn other things.
The vine had been pulled out of the ground so I wasn't burning ivy vine. I
believe burning other things over the area killed the roots enough that the
vine didn't come back.
I learned from another list (CherokeeHealth@yahoogroups.com) that washing
with Octagon soap is the way to go. I've found this works well. The soap
is very hard to find though.

Poison Oak thrives on acid soils. I would lime any area infested w/ latent
roots of same to change it's groweing environment, thereby deterring
recurrent grwoth.
I'd also tyreat the area as if I was trying to get rid of crabgrass. Only
i'd use "scrap" thin plywood sheet/ multiple layers of cardboard, in place

I have a good case of poison oak, therefore have not been gardening much
per se. I was cutting weeds with gloves and long sleeve/pants on, but
to no avail. Somehow I touched the poisonous plant on my face, chest,
stomach and groin. I immediately went inside, washed my hands and arms
with soap and water, went into the bathroom and took a warm shower with
more soap. Guess soap doesn't work as well as alcohol at removing
poison oak, but I didn't know that then.
My immune system is so wound up now, that I only venture out to set the
hose and water; not to weed or spread compost under the camellia bushes.
But, I've found poisonous oak vines all over the backyard. I know I
don't want to torch it. NEVER! But, does anyone know if vinegar will
kill it?
And if you know of a sound solution to reduce the redness and heal my
damaged skin, I'd be much obliged.
Thanks.

I have used Tea Tree oil( Melaleuca alternifolia) to help dry up the
running sores one gets w/ a run in w/ poison oak. Don't use it full
strength, bu t diltuted w/ a massage oil like almond/ jojoba/coconut, etc.
It can be pretty drying and harsh on the skin.
A soap made w/ Jewelweed can be helpful( "Farmers Friend" i think is one
name)

Bunny, you have my sympathy; I've had it twice in my life and then found I
had a similar sensitivity to the oily/waxy leaved ivy up here in Washington
state (no ivy sensitivity while living in Los Angeles most of my life). The
only thing that every really soothed my symptoms was ice. It was better
than the 3% cortisone ointment the doctor reluctantly prescribed. I was
miserable for about 3 weeks that summer. I DEFINITELY would not recomment
what I tried my first time - an over the counter clear liquid that came with
a wooden popsicle stick with which the user was to scrape open the lesions
and then apply the liquid. I had a huge allergic reaction to that & could
barely open my eyes the next day, they and my face were so swollen.
Best of luck to you, and patience while you pass through this.

Have you tried taking an antihistamine, like Claritin? They work for all
day and would damp the reaction to the oak. Also, try some cooled tea on your
skin.
Mary Ann
Burt's Bee's Poison Ivy soap was the only thing that gave me much help.
Take a lukewarm shower and use it on all the affected parts for an
hour or so of relief. I've had huge blistering reactions to both PI
and poison oak over the years. For immediate treatment, when you know
you've been exposed, or you think maybe have been, use a detergent soap
and cool water in a pinch or try to keep around a cleaner like Tecnu to
wash up with. Also, don't forget things like wiping down doorknobs and
railings that you might have spread the oil to on your way into the
house, and those darned shoelaces too. Nothing worse than getting it
AGAIN from your own shoelaces. Also, as you get to a point where
you're starting to heal, calendula lotion is a nice way to soothe the
affected skin without making it feel too "hot" like some oily products
will. And remember that it will go away completely give a little time.
I was sure those marble sized blisters that popped all over my arms
and face were going to leave scars, but they don't.

Boy, someone forgot to tell my poisen ivy - it thrives
on alkaline soils here. The soil is so alkaline that
I've made it a point to put trees in that thrive in
alkaline soils. Even all the compost, mulch, and other
organic methods only go so far - the water underground
here is alkaline. I only wish all the other plants
grew as well as the poisen ivy does.
I have had good luck with lots of compost, leaf mulch,
several layers of thick cardboard, and mulch on top of
that (free wood chip mulch from the electric company).
But the birds bring it right back so it's an on-going
battle.

I have read that applying hot water to the affected
areas will offer relief. I got a dose of poison ivy
over the weekend, and have been using the hot water
applications, and they do in fact work well. The

Some of the poison oak on my land seems to be turning into little trees, actually, most of it is growing like a vine around one of the established oaks - which seems to be the mother lode Pat suggested I check for. There is also, on the opposite side of the lot, a dense stand of low brush with leaves that look just like poison oak. Time to call the extension agent and ask what the heck that is.
The soil is soft right now so it was easy to pull up the roots of the uprights, and I cut back as much of the vine as pruning shears could handle, this afternoon I'm going back with a little saw for the rest. After taking the precautions of wearing heavy gloves and long sleeves/slacks etc and then got slapped in the face by one of the smaller pieces of vine I was pulling out - I love it. Now we'll find out if I'm still immune. I cleaned my face and glasses off with handi-wipes and then with rubbing alcohol back here at home, we'll see. Might as well go back and finish the job in the meantime!

Deanne, If you pull it out, then cover yourself completely and wash or throw away what you were using. Also don't do it when it is hot, as when you get hot the pores in your skin open up and you have more of a chance to react. One day, I ran a 6 mile race and came home on an early warm spring day. I decided to tie up my very large Rue plant. I had to wrap my arms with the twine around the bush and I was wearing sweat pants ( thank goodness ) and a t-shirt. I got the same as poison oak poisoning from where my gloves ended to the sleeves of the t-shirt and on my neck and chin. It was not nice. I did not know Rue would do that. So, be careful of the poison oak, as I had never gotten it when other had in the past. Sue

But do be careful if you haven't recently tested your non-allergic status.
I've known people who once weren't, but late became, allergic.

Is poison oak a real tree? If you want to kill a tree, a harsh way is to cut it down and bore a hole in the trunk and pour salt or hydrochloric acid in the hole. Continue until the tree is really dead. Hydrochloric acid is probably better than salt!
You can bore several holes, it goes faster then.

Many people think Poison Oak ("Rhus quercifolia") and Poison Ivy ("Rhus
radicans") are the same plant but they are not, cousins yes but not the
same. Poison Ive is more widespread than is Poison Oak and most people will
have the PI rather than the PO.

I don't think it has anything to do with the PI, but rather with their

doing around a house and yard, taking your money and promising to return at

Good point about power tools. At the moment all I have to work with is a little handsaw and pruning shears, but next time I pull PO vines down out of the *real* oak tree I'll wear a hat with a sturdy brim and netting over my face or look for a face shield. Maybe beekeeper's headgear.
Luckily I still haven't seen any reaction to the vine hitting me, but - as you said in another message - who knows when my immunity will weaken and/or the strength of the PO will increase.
Now I'm wondering what the heck to do with all the PO I've cut down. Tie it up in plastic bags, label it, and take it to the dump? I can just imagine it growing new roots and coming back to life like something out of a horror movie (!), it's nasty stuff. I'd originally intended to plant barberry where the PO is being cut down and now hope the barberry will be able to overwhelm the poison oak roots.

What I do with weeds like that (noxious weeds, I call them) is put them into black garbage bags and close the top with a stone or brick and leave them for a year, after which they (hopefully) are slime and can go on the compost heap.
Now and then a stone falls off, of course, and they only partially disintegrate. Or weeds are so woody that they rip holes in the garbage bag that I don't notice...
I can now put it all into the warm composter, which is something like the huge compost heap they have in a city near us, which gets the garden leavings from everone in every city near here, and makes a really huge compost heap or windrow. From this we get our city soil, which has the pH of 7.8!

Urushiol isn't a poison, it's an oil that causes a histamine reaction. =
Oils don't easily compost. From WebMD:

No, but it won't do you a whole lot of good.
During the composting process, the poison oak-including the urushiol =
oil, the irritating substance present in all parts of the plant-will =
break down into its component parts. Thus the finished compost will harm =
neither you nor your plants (no itchy tomatoes). No one seems to know =
just how long this decomposition will take, however. Poison oak is a =
woody plant, so it should require lengthy composting-six months, at =
least. If you do compost it, add plenty of nitrogenous material (manure, =
leather meal, etc.) to assure a "hot" pile, which will cook faster.
Meanwhile, that pile will be hot in another sense. Like poison ivy, =
poison oak becomes more toxic as it dries; it loses mass (water), and =
the urushiol oil becomes more concentrated. If you're allergic to the =
weed, it's going to be a long, unpleasant winter as you chip the brush =
and build and turn the compost. Unless you and yours are allergy-free, =
I'd recommend against composting.
The standard way to dispose of cleared poison oak is to bury it, thus =
handling it only once. Don't burn it; the rising smoke will afflict any =
skin it comes in contact with. Wear protective clothing, and wash it =
separately (and yourself, of course) immediately after finishing the =

I don't know if it can or not. Seems that if you threw a lot of it on

Even though I haven't reacted to poison oak or ivy *yet* I still want to remove as much of the PO from my property (about 3/4 of an acre, not that big) as possible, just in case. Some day I won't be paying attention and won't be dressed properly and my first allergic reaction will probably strike. So there's that concern, and also the fact that people helping with projects might be allergic. One of the guys putting up the fencing said he was.
Although he didn't help himself out much - working in short sleeved t-shirts and not paying any attention to whether the plants he touched were or weren't poison oak. That I don't understand - I went out as covered up as possible and wore heavy gloves before cutting back PO in the areas where the fence was going up, despite never having had a reaction before.
Thanks, Pat, for clearing up what to do about the vines. I did just pull down the ones that came down without resistance, and then cut all the rest at the base in hopes it would do them in. I was concerned that what I didn't pull down would be able to make up for being separated from its roots by feeding from the oak, but since they're all clearly dying at this point I guess that isn't the case. I hope the oak is taking a nice big sigh of relief!
I'm grateful for all the advice on what to do with the PO after it's cut down or pulled up. I'll definitely bag it all up, and label it clearly, and see what happens in a year. There are a couple spots where it would be out of the way and undisturbed. Maybe also ask the extension people what they advise, and whether there are local regulations about it. I have a longish list of questions for them already!

No no no, that's why I'm on the list - the best way to get a complete picture on any subject is to hear about it from different points of view. I like the idea of poking large holes into a compost pile, too, I don't remember that being mentioned before and for weaklings like myself that sounds easier than turning compost piles.

I doubt that a dog's getting into the cut or shredded vines is any worse
