UCCE Santa Clara County Composting Education Program

UCCE Santa Clara County Composting Education Program We are a volunteer-based group of Master Composters teaching the art and science of composting through free workshops and events!

The University of California Cooperative Education (UCCE) Composting Education Program is a partnership with the cities and the County of Santa Clara that seeks to educate our community about composting. In addition to a Masters training course the Program offers Community Classes throughout the county as well as provides educational support for teachers. Master Composters teach residents how to b

uild compost piles and worm bins, then how to apply the resulting material in their gardens. Master Composter volunteers also provide presentations to local schools, community organizations and events.

Is your compost ready yet? If you’ve been turning and watering your pile for months, here’s how to know when your compost is ready to use! 🌱

Finished compost is:

Dark brown and crumbly, like rich soil
Unrecognizable- no more banana peels or leaves in sight
Earthy-smelling, never sour or rotten
Cool to the touch, since the microbes have finished their work
Moist like a wrung-out sponge

When your pile checks all these boxes, it’s ready for your garden beds, containers, or as a top dressing for your soil!

Video description: A UC Master Composter stands in an outdoor garden beside a compost bin, explaining how to tell when compost is finished. The video includes close-up shots of her hands holding dark, crumbly finished compost and squeezing a handful to demonstrate its texture and moisture, with views of the compost pile and garden greenery throughout.


¿Ya está listo? Si has estado removiendo y regando tu pila durante meses, ¡aquí te explicamos cómo saber cuándo tu compost está listo para usar! 🌱

El compost terminado es:
De color marrón oscuro y desmenuzable, como tierra fértil
Irreconocible: ya no se ven cáscaras de plátano ni hojas
Con olor a tierra, nunca agrio ni podrido
Fresco al tacto, ya que los microbios han terminado su trabajo
Húmedo como una esponja escurrida

Cuando tu pila cumpla con todos estos requisitos, ¡estará listo para tus camas de jardín, macetas o como abono de cobertura para tu tierra!
