Mulch vs Compost on a slope
I recently bought a home in Washington and inherited a yard full of problems, namely a serious infestation of horsetail, poorly selected plants (ie hostas in the front, southeast facing yard in an area where deer roam about). Anyway, I've been working on it, and the horsetail and I have engaged in what I have learned will be a long battle. My question is this: my front yard was covered in beauty bark/mulch which I've left in place, but I kind of hate it. Is rather use compost to enrich the soil (and tick off the horsetail), but my front yard is also sloped so I'm not sure if getting rid of the mulch is a good idea (I'm concerned replacing it with compost will result in erosion as the rain/wind washes it away). I've got a nice patch of phlox (subulata) to help, but it's not fully filled in the area just yet.
