What Plants Actually Survive an Ocean-Facing Point Loma Slope
Plants on an ocean-facing Point Loma slope need to tolerate salt wind, hold soil on a grade, and survive with minimal irrigation once established. We lean on deep-rooted natives and Mediterranean species that have proven out on Coronado's exposed beds, terracing the planting so roots hold instead of washing out.

Point Loma's slopes below Sunset Cliffs take wind off the water most afternoons. That wind carries salt the same way it does on Coronado's bayfront, just with more elevation and more grade to manage underneath the plants.
The lesson we brought over from Coronado's ocean side
We have pulled agaves on ocean-facing beds two streets from the bay in Coronado, plants that read fine on a catalog photo and rotted at the crown within a year. The same caution applies on Point Loma. A plant that handles bay-facing salt on a flat lot does not automatically handle wind-driven salt on a slope, where drainage and exposure both work against it.
Pittosporum has held up for us on Coronado's bayside through winter storms, and we specify it on Point Loma slopes for the same wind tolerance, planted above the drain line rather than in a low spot where water sits.
Why the slope changes the planting plan, not just the plant list
A slope changes root spacing and planting depth as much as it changes species choice. We cut ocean-facing Point Loma beds into 18-inch terrace shelves so each row of planting has level ground to root into, with 4-inch drain rock and perforated pipe behind any retaining wall handling the water the plants can't manage alone.
On a slope job off Catalina Blvd last spring, about a 25-foot run at roughly 30% grade, we set plants 24 inches on center along each terrace shelf instead of guessing at spacing on the open face. That job ran close to $14 per gallon-can plant installed, with drainage work billed separately.
What we plant, and what we stopped planting
Drought-tolerant, deep-rooted species do the work on these slopes. Agave and other succulents that thrive on Coronado's protected inland beds get left off the list here, because the combination of wind, salt, and grade rots them faster than they can establish.
We do not guess at this block by block. Sam walks the slope, checks which direction it faces and how much wind it takes off the water, and draws the plant list against that exposure before anything gets ordered.
Do Point Loma slope plantings need more irrigation than a flat lot?
Less, once established, if the species are chosen correctly. Drought-tolerant slope planting on Point Loma needs regular water only through the first season while roots establish. After that, drip irrigation set to the terrace shelves, not the open slope face, is usually enough.
Overwatering a slope planting is its own failure mode. Water pools at the base of a terrace shelf, and the plants we chose specifically to avoid rot end up sitting in it anyway if the drip lines are not placed correctly. We run 0.5-GPH emitters on those shelves rather than the 1-GPH heads we'd use on a flat bed, since runoff already does half the watering after a storm.
