Short answer: Spread mulch about 2 to 4 inches deep over clean, weeded beds, and keep it a few inches away from trunks and stems. Refresh it about once a year. Mulch holds moisture, keeps weeds down and protects the soil, which matters in our dry summers.
Weed first
Pull weeds and clear old debris before you mulch. Mulch smothers new weeds, but it will not stop established ones.
Get the depth right
About 2 to 4 inches is a good range. Too thin and weeds push through. Too thick and water struggles to reach the roots.
Keep it off the trunk
Pull mulch back a few inches from tree trunks and plant stems. Mulch piled against bark holds moisture and can cause rot and attract pests.
Pick a mulch that suits the bed
Wood chips and bark suit most beds and slowly feed the soil as they break down. Coarser mulch stays in place better on slopes.
Refresh once a year
Mulch breaks down and thins out. Top it up once a year, usually before the hot, dry months.
Water as normal
Mulch reduces how often beds need water, but new plants still need regular watering until they settle in.
