Husband and wife Mark Rinaldi and Debbie Imsland have long been interested in sustainability. At home, they were conscientious about conserving water, taking care not to water the lawn too often or stay in the shower too long.

But it wasn’t until Debbie attended one of our Rainwater Harvesting Workshops that they considered making some major changes to their Gardena home. It started when they installed rain barrels in their yard, but it wasn’t long until they turned to their lawn.… Read more >>

The Real Truth About Fake Grass


True or false? Artificial turf or “fake grass” is a great alternative to traditional lawns for water-scarce Los Angeles.

No bigger than a baby’s fingernail, the gold-spotted oak borer (GSOB) can devastate a 300-year-old oak tree that has withstood storms and quakes and even the quick and astounding rise of urban pollution in the 20th century. But if individual trees were all that was at stake, the oak borer wouldn’t pose such a threat. The truth is, this invasive pest could wipe out every native oak in California.… Read more >>
