Mulch your flower beds to insulate roots and protect them from freezing temperatures. 

Move potted plants indoors to a cool, well-lit area to keep them healthy through winter. 

Cut back dead or damaged stems to promote new growth when spring arrives. 

Water your plants sparingly during winter to avoid root rot from excess moisture. 

Use frost blankets or garden fabric to shield plants from harsh winter winds and frost. 

Choose hardy flower varieties that can withstand colder temperatures and still attract hummingbirds. 

Regularly check for pests or diseases that can thrive in winter and address them promptly.
