What are you using to kill poison ivy? Just regular old roundup? I mow and till for my tree plantings, but I got the stuff coming back strong in last year's trees. It's been so dry that I went out and watered all the trees last weekend. Sure enough, I got poison ivy!
Looks like it is starting to sprout up around this year's new trees also.
I have weed barrier around all the trees, so it should be pretty easy to spot-spray the poison ivy without hitting the trees.
Is there a better chemical to use than roundup?
