Winter time is a great time of year for work in the garden, especially in California. While it can be a little cold and wet, winter time is a good time to work on the bones of the garden. Replanting can be done in needed sections so plants are well rooted for spring growth. Pruning and trimming is best done now, when plants are dormant and most are done blooming. Irrigation systems can be checked and repaired so they are ready for the spring watering season and leaks and alterations are made. Slightly later in the season is a good time to fertilize plants to give them the nutrients they need for spring. While the garden may be dormant, this is a good time for the gardener or paid gardening service to get in some winter time care.
