Not outdoors, and nothing needs starting indoors yet either — December sits in zone 8's off-season. The next task on the calendar: start seeds indoors for onions (Jan 4 – Jan 18).

What should a zone 8 gardener do in December?

Order seeds before spring sellouts, plan beds with the plant spacing calculator, and build your seed-starting schedule so trays are ready the moment the calendar turns. Off-season planning is why organized spring gardens look effortless.
