I have a slope approx 10 yards by 20 yards. It was originally covered in heavy brush and some broken pine trees that had been there for over 20 years. I had it cleared down to basic pine needle mulch, with mucho roots and vines protruding. I have planted probably 100 purple wintercreeper plants so far, trying to spread them out as evenly as possible. Basically I just want a decent ground cover that will not tower over the house and stay fairly low.
However, the native plants, ie: poison ivy, some shrub like plants, virgina creeper, poplar trees, walnut trees, etc have begun to reemerge and outpace the groundcover I've been planting. It looks like it is getting out of hand. Is spot treating with brush killer the only way to keep this in line until the wintercreeper takes off?
