Label your plants because by spring those plastic tags you have, may be faded or break and blow away. Using metal labels or placing the label underground in a plastic bag seems to be more effective. I like to use the metal labels pressing them deeply into the ground to prevent their being pulled out.
Remove all leaves, preferably in the fall, but if not, in early spring. This will help to minimize next year’s pest problems such as slugs, fungal infections and foliar nematodes. You can then add a thin layer of mulch for crown protection. This is also a great time to get all those spring bulbs in the ground for your enjoyment next year.
