Answer: You're fortunate to live in such an idyllic setting! Most plants can be safely fertilized as long as they're actively growing. As winter approaches, it's a good idea to cut back, because some fertilizers stimulate tender green growth that is more succeptible to cold. When plants stop growing they're going through a resting phase and should not be encouraged to grow until they're ready. When you see buds start to swell or leaves unfurl, you can begin fertilizing again.
