In southern California, it seems, the majority of homeowners, landscapers and gardeners have some sort of slope to deal with. In most cases graded slopes are extremely difficult to plant, often with poor, compacted soil and steep grades. There are several variables to consider when choosing plant material for a slope: the location and microclimate involved (inland, coastal, high winds, extreme temperature…), the direction or exposure of the slope, erosion factors, soil type and the stability of the slope and soil conditions.

Suitable low water and low maintenance choices for a slope, to replace traditional generally sterile plantings of ivy and ice plant, include an assortment of regionally appropriate grasses, ground covers, shrubs and trees. These plants are naturally adapted to our environment and require fewer resources and less labor to care for them. By using a variety of plants on your slope, you can achieve a refreshing, diverse and visually stimulating slope landscape. Proper spacing and plant selection will cut down on pruning maintenance and competition for moisture. The diversity in the landscape will bring back the pollinators, butterflies, hummingbirds and songbirds.
