I have constant problems with poison ivy. It's partly because this neighborhood was developed from mature woods in the 80s/90s and partly because I left most of the backyard wooded. It took a decade just to get the scrub trees (like thorny locust) cleared out. I like the semi-natural look I have.
But it is partly because 2 adjacent neighbors totally ignore their yards next to mine. One has a drainage easement through their back yard (10' from my fence) and they basically ignore everything on the side near me. The other has 10' of brambles near my fence and just never bothers with that area. A 3rd neighbor is basically absent for some reason (I think the property is involved in a divorce dispute), and while he mows the yard every couple of weeks, he pays no attention to the edges.
So I am constantly fighting off poison ivy coming in through the fence.
I used to have little reaction to it, but several years ago, I got a full body rash from it. It was a miserable 2 full weeks. Some of the poison ivy in the neighbor yards is mature enough to produce berries and the birds evidently drop the seeds all around the yard. New plants spring up out of nowhere even near the house.
I saw the first new poison ivy plants leafing out 2 weeks ago. They are now fully leafy. I am an organic gardener. But that garden/flowerbeds/lawn. For poison ivy (and also rampant honeysuckle, wild grape, and some vine I haven't identified), I turn to Brush-B-Gon!
So today was "Spray Day". I filled up my large pressure sprayer (portable, but just barely) and made the rounds. I was shocked at how much poison ivy was around the yard and how mature some of the plants were! That's partly because I have been clearing problem spots and revealing places I haven't looked into for years. For example, I discovered (to my horror) that there is a huge poison ivy vine coming up over the fence and growing 20' up a tree in MY own yard!
I can pretty much kill off most of the plants in my yard, but I can't get rid of the sources. I spray carefully (short controlled spray individual plant by plant) through the fence as far as I can (the neighbors have no landscaping near the fence), but there is always more growing back the next year.
So I have a dilemma. If I ask the neighbors to control/spray the poison ivy in their yards, they will spray wildly right through the fence on a windy day and kill all my plants and flowers. If I don't mention the problem, I will have poison ivy forever.
Maybe I should ask them if I can spray in their yards and do it carefully...
Anyway, I went around the yard spraying poison ivy plants with great pleasure. I can't wait to see them turn brown and die! It was a sunny and nearly windless day, so it was safe. And only an hour later, all the leaves were dry, so I know they soaked in the spray.
I'll try to remember to post pictures of the dead poison ivy next week...
