Child of the drought.
At the height of California's most recent serious drought, Mrs. Rorie Skei began to landscape the bare 1/3 acre around her house in Thousand Oaks, using mostly California native plants.
Except for a small vegetable garden, lawn, and some pots, her seven-year-old garden now consists almost entirely of drought-tolerant California natives. "Many common landscape plants such as raphiolepis and photinia have native counterparts that grow well in our climate,' she says.
Fall, just before winter rains, is the best time of year to plant any drought-tolerant natives or non-natives. Mrs. Skei handwatered regularly the first year after planting, then only occasionally during hot summer months.
In her landscape, natives serve many different functions. The house backs up against unspoiled open space, so the garden blends into the hillside, attracting birds and helping buffer the house against possible chaparral fire. To reduce fire danger further, Mrs. Skei prunes regularly, removes dead wood, maintains a cleared space between house and hillside, and keeps plants next to the house well watered. (For more on native and non-native low-fuel-volume plants, see page 162 of the September 1984 Sunset.)
Mrs. Skei has found that small plants generally establish themselves faster than large ones. For example, after only five years, two coast live oak trees (Quercus agrifolia) reached nearly the same size-- even though one was planted from a 15-gallon can, the other from a 1-gallon can. And except for the lawn and vegetable areas, none of the soil has been amended. Experience has shown Mrs. Skei that amended soil dries out two to three times faster than unamended soil.
