Not sure of how solid it is. I haven't been brave enough to venture towards the center yet, and I'm scared to death once I'm on my feet because I'll feel it give a little with my weight. I know that it's holding all of the vines, plus some downed green oak limbs, about four inches worth of dirt and matted leaves, a bush of some sort, and a lot of pokeweed. I removed the limbs, some of the leaf and dirt litter, and at least a fourth of the vines. I'm hoping that if I can clear it up, that maintenance on it will be simple. I have a surplus of house shingles, but I wouldn't want to add to something that works okay. (Unless laying shingles across the vines would help.) Rain falls through the tin at the point where those vines are most dense on the roof. Since my boyfriend is home today, I feel more comfortable sending him up there, or just having someone hold the ladder.
I also had problems with my two plum trees, they had sprouted at least eighty suckers inside of the pens(dirt floor) that had a few years to harden, and the limbs had twinned through the wire and tore it up. I finally got rid of those little horrors, and the pens they messed up.
The rash I had gotten from this plant was unusually bad. I've brushed across it all of my life without a problem, but I read that the sap is the irritant, and the cutting and tearing probably slung that mess everywhere. I was wearing cloth gloves, this time, I'll sleeve up and put the leather gloves on.
I've had poison ivy that hurt less. It seemed to get worse and worse despite I was taking enough benadryl to knock out a horse, and smothered in calamine and hydrocortisone which burned on the rash to begin with. I added Epsom salt and about a tablespoon of VetRX to a bath and got better, and longer lasting results than anything else the pharmacist recommended, haven't hurt or itched. So, my animal's medicine worked better than my own.
I've been busy with a new litter of pups because my neighbor won't keep his dog in the yard, (my dog is fenced but not fixed, apparently they could still get it on with the fence there.) Plus the dog came back two nights in a row this week messing with my chickens. None of them are dead, but I don't think the dog's tasted blood yet, and my old game rooster sleeps on my porch at night, and has his natural spurs. The dog was bleeding when I shined the lights on him, and ol Ceasar the rooster was looking around with his hackles up on end.
Anyways, once I get to the root of the problem (pun intended) and kill the vines, I want to plant some muscodine grape vines or honeysuckle to shade out anything else. (Virginia creeper grows along a neighbors' fence adjoined to my original grapevine, and it won't grow into it.)
