I am brand new to the board, and to gardening in general. Our yard is on the wild side, to say the least, but I'm working on it. One area that I'd really like to do something about is the top of this huge rock that is along the back line of our yard. It's right across from the deck, and pretty much the first thing you see when you go outside. There is very little soil on the top...weedy grass grows in the pockets and crevices on the top of the rock. In the summer, that gets to be foot high, or more, and looks terrible. I guess I can nag my husband all summer long to get out the weedwacker, but I would much prefer to see something growing up there that is low, green , and matlike...some sort of groundcover? Given that I can't exactly dig a hole and plant something the conventional way, is there anything I can get to replace the grassy weeds that would look nice?
The weeds are growing in pockets that aren't more than a couple inches deep, and come up with a simple tug. I can't strip it all off and leave it at that, since it would be a tripping hazard and slippery...I do walk that back line of the property on occasion with my small dogs. Maybe one a day I'll be up there. The total area is a strip pf about 15-20 feet by 3-4 feet. We have moss growing on the left and right sides of the yard which I sort of like (I know most people probably wouldn't care for that). I thought about trying to get the moss to replace the grass up there, but I think that one strip receives too much sun. There's a little patch of moss growing at one edge of the rock, where it starts to get shady. I was reading about Irish moss, and was wondering if that might work?
So basically, I need to know, what, if any plants grow in shallow little rocky crevices...fairly sunny, and perrenial. Sorry this is so long, and thanks. I'll try to post some pics of the area
