Question
Hi Dan:
I had my driveway paved about 3 years ago. One section of the driveway
that is close to the house and receives more shade than other areas has
a green tint. When I get down there and look closer, it appears that
moss is growing on the surface. Have you ever heard or seen such a
thing? And if so, is there any solution? I want to resurface the driveway
this summer but not until this situation is corrected. Thanks in
advance."
Kevin, it sure can be moss. Grass and weeds will grow through and on top of ashphalt in a very short time on old abandoned situations, especially if there are cracks. There are moss and fungus problems on roof that are handled by treatment with zinc or copper to reduce the dark streaking on roofs. An occasional wash down with a copper solution may do what you want. Most hardware/box stores carry it as root killer in the plumbing section - blue crystals. You might try a small section to see if this solves the problem.
