Come and load up on free tree trimmings to use as mulch for suppressing weeds, conserving water and just all-round cheering up that spot in the garden that needs cheering up! We have shovels, all you need to bring is bags or buckets. Consistency ranges from acidic pine needles for acid loving plants like blueberries, citrus and the omnipresent Alameda front-yard Camelias and Rhododendrons to thicker chips of chopped cedar and eucalyptus. Save some money using free bark-mulch this season!
