1. Time for a Trim

January is the perfect time to prune your roses in SoCal! Grab your sharp shears and cut back about one-third of the plant, removing dead or weak branches to encourage fresh growth. Don’t worry—roses love a good haircut, and this will help them produce strong, beautiful blooms come spring.  

2. Refresh the Soil with Mulch

Even in Southern California, winter nights can get chilly, and a layer of mulch helps protect the roots. Spread 2–3 inches of mulch (such as bark or compost) around the base of your roses to retain moisture and keep the soil temperature stable. This is especially helpful if you're in inland areas where frost is more common.  

3. Water with Care

Southern California's winter rains usually provide enough moisture, but if you hit a dry spell, give your roses a deep watering every couple of weeks. Since our winters are mild, roses may still have some leaves, but don’t overwater—too much moisture can lead to root rot.  

4. Keep Pests and Disease in Check

Cooler weather doesn’t mean pests disappear! Check for aphids, spider mites, and mildew, especially if there’s a warm spell. A simple spray of neem oil or insecticidal soap can keep problems at bay. Also, remove any fallen leaves or debris around the base to prevent fungal diseases.  

5. Feed at the Right Time

Hold off on fertilizing until late January or early February. Once new growth starts to appear, give your roses a dose of organic compost or a balanced fertilizer to help them wake up strong. This will give them the nutrients they need for a spectacular spring bloom.  

6. Take Advantage of SoCal’s Mild Weather

Unlike colder regions where roses completely shut down, SoCal roses often keep a few leaves or even bloom lightly through winter. If you’re near the coast, your roses may not need as much protection from the cold, but if you’re in a high desert or inland area, be mindful of occasional frost and cover tender plants if needed.  

By giving your roses a little attention in winter, you’ll be rewarded with an explosion of color when spring arrives. So, sharpen those shears, refresh the mulch, and get ready for a spectacular rose season in Southern California!
