Preparing Your Garden for Planting
To maximize your winter vegetable harvest, proper soil preparation is key:

- Watering: Although San Diego winters are milder, consistent watering is necessary, especially if dry spells occur.
Companion Planting and Pest Control
Pairing winter vegetables with the right companion plants can enhance growth and deter pests:
