Vegetables Suitable for January Planting
January is an excellent time to start planting a variety of cool-season vegetables in Southern California due to its mild winter climate. Many vegetables that thrive in cooler temperatures can be sown directly into the garden or started indoors for later transplantation. These crops benefit from the region’s relatively frost-free environment, allowing for an extended growing season.
Cool-season vegetables suitable for January planting include:
- Leafy greens: Spinach, kale, Swiss chard, and lettuce varieties flourish in cooler weather and can be sown directly into garden beds.
- Brassicas: Broccoli, cauliflower, cabbage, and Brussels sprouts do well when started indoors in January and transplanted in early spring.
- Root vegetables: Carrots, beets, radishes, and turnips can be directly seeded into the soil.
- Alliums: Onions and garlic benefit from January planting as they require a long growing period before harvest.
Starting seeds indoors for certain crops, such as broccoli and cauliflower, allows for a stronger transplant and earlier harvest. Using seed trays with quality seed-starting mix and maintaining consistent moisture and temperature will improve germination rates.
Herbs to Plant in January
Herbs are a versatile addition to any Southern California garden and many thrive when planted in January. The cool temperatures help establish strong root systems before the warmer months arrive.
Recommended herbs to plant in January include:
- Parsley
- Cilantro
- Chives

Many herbs prefer well-draining soil and a location that receives full sun to partial shade. Starting herbs indoors or purchasing young plants from nurseries can provide a head start, especially for slower-growing varieties like rosemary and thyme.
Flowering Plants for January Gardens
January is also a good time to plant certain flowering plants that will bloom in late winter and early spring. These plants take advantage of the mild temperatures and can add color and fragrance to the landscape during the cooler months.
Recommended flowering plants include:

Planting bulbs such as tulips, daffodils, and hyacinths is also appropriate at this time, especially if they have been chilled properly before planting. These flowers will emerge and bloom in the spring, providing early-season interest.
Soil Preparation and Planting Tips for January
Proper soil preparation is crucial for successful January planting in Southern California gardens. The soil should be tested and amended as needed to optimize fertility and drainage.
