Build Your Own Compost at Guasti
March 1 @ 1:00 pm - 3:00 pm
Learn how to recycle organic resources, such as yard trimmings, as well as fruit and vegetable waste into compost for gardens. Join us at Cucamonga-Guasti Regional Park on Saturday, March 1, from 1 pm. to 3 p.m. for a hands-on education activity. All supplies will be provided, while they last.
Instead of putting organic waste into the garbage to be hauled to the landfill, learn to compost. All ages are welcome.
Admission is $10 per vehicle. Make a day out of this educational event and pack a picnic or come and enjoy a day of fishing at our lakes or enjoy the playground and splash pad. Leashed pets are welcome!
Cucamonga-Guasti Regional Park is open daily from 7:30 a.m. to 5 p.m., and is located at 800 N. Archibald Ave., in Ontario next to Top Golf.
