The garden above was created as a private test garden in San Jose, California, and features California native plants in a wild, naturalistic design, according to the client’s wishes. Featured in the photo from left to right are Ceanothus ‘Yankee Point,’ Western Redbud, California Wild Rose,* and Ceanothus ‘Dark Star.’

There was no tilling or soil preparation for this site (other than weed clearing), and no fertilizers were added to the soil prior to or after planting in the late spring of 2010.

Planting holes were dug no larger than the plant containers to encourage the roots to grow through native clay soil. During planting, no attempt was made to loosen the soil around the rootballs and the soil surrounding the rootballs was not disturbed except to briefly and lightly brush the soil with gloved hands. Six inches of redwood mulch was added to the site to suppress weeds and retain moisture. Surprisingly, the mulch has not needed replenishing!

Immediately after planting, each plant was watered in for approximately 15-20 minutes, thoroughly and deeply saturating the rootball and surrounding area. Following the initial watering (during their first summer), plants were watered every few days if needed, tapering off to watering twice a week in the cooler weather of fall, at which time plants were watered once a week until winter rains arrived consistently enough to rely upon. Since the plants’ first year in the garden, there has been no supplemental irrigation to this site! Pruning and weeding is performed just twice a year, making this garden fairly low maintenance. Weeds are hand-pulled to avoid the use of pesticides which would harm the environment and creatures (including humans) enjoying it.

Amazingly, these plants bloom beautifully and reliably each spring. Native butterflies, birds, and lizards are happy in this habitat and iridescent native bees frequent the garden. Photos were taken in the Spring of 2017.

*California Wild Rose (Rosa californica) can be utilized as a barrier to intruders as it spreads freely by runners when happily situated, forming a dense thicket over time if left unchecked, so plant with caution!
