My central air conditioning unit is located in a spot where the eaves are so deep that even after lots of rain, it's still bone dry, but bindweed finds the area delightful and it's eating my air conditioner. I thought of covering the whole area with plastic and then a few inches of stones right up to the foundation, but I have another concern. In winter, it's not uncommon for several feet of snow to drift into that corner. When it melts, I'm not sure I want that much water ponding in the plastic and overflowing along the edges near the cinder block. The basement's always been dry, but still, something about the plastic idea seems iffy. So, some sort of landscape fabric seems like a better option.
Regardless of the material on top, I'm thinking of edging it with Trex buried with just enough above ground to contain 2-3 inches of stones.
