Landscaping in Charleston is a Kanawha Valley lot with a hill behind it or a river-bottom yard that stays wet. South Hills properties are steps, walls, and drives cut into the slope. Valley-floor yards in Kanawha City, the West Side, and the East End are smaller and heavier, and they take water when the grade from the hill has nowhere else to go. If the uphill wall is wet, that leads the call.
Shade from the ridge grows moss and thin grass. A single tree on a small lot fills the gutter and leans over an older roof. Retaining walls that bow are not a planting project first. They are the thing holding the mountain off the house. Down on the flat, the problem is a downspout at the back step and soil that never dries in the valley fog. Describe which of those yards you have.
Mowing a terrace is not rebuilding a washed drive. Leaves come off the hill all season. Erosion after a hard rain will strip a bed on a steep face. Irrigation is secondary to getting water away from the foundation, and any system still needs a winter shutdown. Do not aim spray at the uphill sill. Access for debris may be a steep street with no place to stage. Say so.
Plants have to live with shade on the hill and with sticky valley air below. This is West Virginia, a mountain valley, not a coastal garden. Deer and brush at the edge of a South Hills lot are ordinary. A tiny city yard by the river is ordinary too. Say wall, drain, tree, or cut so the work matches the slope.
Walk the uphill side after rain. Landscaping in Charleston should keep hill water and river-bottom water out of an older Kanawha Valley house. Call the number on this page.
