Q: I have chopped down blackberry canes into fairly small pieces in my back yard, The area is a fair size. Can I leave them on the ground, or can these pieces of cane resprout. I'm not interested in using any kind of chemicals. If I dig up the roots, is it possible to smother the blackberries by covering them with heavy black plastic? Or is that a waste of time. I realize blackberries are very difficult to remove.
Q: I am installing a permeable driveway (Unilock Turfstone) at my house in Portland. I read your article on best types of grass mixes in Oregon. But what about driveway grass? Ideally I would like a grass with low maintenance, less mowing, and for daily parking with car traffic. The driveway is in southeast corner of house and gets full sun, except when parked on in evenings.
