The front yard of the Point Loma home owned by Nina Ronstadt and Ken Klestinec once had a lush lawn and a cottage garden. But years of drought and limits on water use killed most of the plants. What was left, said Ronstadt via email, was “dried-up lawn and ugly dead landscaping.” She wanted to replace it with a meadow of drought-tolerant ground covers and a curving path, “but our 10-year-old daughter asked, ‘Where will I have a tea party?’ and ‘Where will our dog Cleo play ball?’” So, a circular patio area was added to the plan.
