Compost & Mulch Instructions
(Made from Castro Valley’s food scraps & yard trimmings!)
Adding compost brings life to soil. Just one teaspoon can have more than one billion beneficial microbes.
New gardens: Add 4-6” before planting.
Established gardens: Add 2-4” before each planting.
Potted plants: Add 1 part compost to 3 parts potting mix.
New trees and shrubs: Add a 5 gallon bucket for every 1-2 gallons of the tree/shrub container size.
Mulch conserves water, enhances the growth of plants, suppresses weeds, and controls topsoil erosion.
Use gloves to evenly spread 3-4” of mulch over bare soil.
Replenish annually or as needed.
Keep recycling food scraps in your green organics cart to continue the cycle!

A healthy garden starts with healthy, living soil.
It is something of a miracle to see broccoli stems, orange peels, and fallen leaves change into dark, sweet-smelling earth. Composting—collecting organic materials and combining them in a manner that will encourage their breakdown—makes use of the natural process of decomposition to create a high-quality soil conditioner.
Organic material is different forms of living or dead plant and animal material. It is compost. Fallen leaves. Grass clippings. Woodchips. Sawdust. Manure. Kitchen scraps. It is the cornerstone of organic gardening and a universally recognized soil amendment. Above all, organic matter is food for the living organisms in the soil. And keeping soil critters well fed ensures that all the other qualities a gardener seeks in soil will gradually increase. Adding organic matter ensures that soil will have:
- good structure
- sufficient water retention
- proper drainage
- nutrient supply and cycling
- disease resistance
Your own homegrown compost is a slow-release fertilizer. When you distribute it in your garden, you are amending the soil—and, ultimately, increasing its nutrient content and its nutrient-holding and nutrient-cycling capacity.
StopWaste.Org's Bay-Friendly Gardening program of Alameda County is no longer subsidizing the price of backyard compost and worm bins. For more information, please visit StopWaste.Org's website.

Compost and worm bins are available for purchase at non-discount prices from a variety of retailers. Please click here for a listing of retailers.

Grover's Wonder Grow is the result of Alameda county's organics. Your yard trimmings and food scraps are composted at their Vernalis facility using 100% organic processes, and brought back for a rich soil amendment to your garden.
ZBest's Smart Grow comes from Alameda county's commercial food waste efforts. Restaurants and event venues across Alameda, Contra Costa and other Northern California counties send material for compost at their Gilroy site. There it's composted using Ag Bag technology. The resulting soil amendment is ideal for commercial and landscaping applications.
We have 3 colors of colored mulch: Red, Brown and Black. These are the results of wood recycling efforts at Davis Street.
Also available at the Garden Center: Deco Bark, Redwood String and Playground Chips.
