Sounds like my issues with honeysuckle and trumpet vine.Looks like we're having the same day! Bindweed is part of the grumble here for years, though, nothing new. Pick squash--pull bindweed. Manage the hoophouse--while digging bindweed. Enjoy the dahlias--while bindweed blooms dramatically across the neighbor's barn in the background. Eat an apple off the tree...pretend not to notice the newest climber on the fence.
Sigh. I love my garden but bindweed is such a pain. Hope you can manage to dig up all the root before it becomes part of your forever cycle. If not...well. At least hummingbirds think it's great.
I need a blow torch...
