I also bought a hummingbird feeder last year post season. When should I start putting it out with sugar water? Do I need flowers around it to attract hummers?
May is the earliest I ever get Hummingbirds up here in SW Wisconsin, so since you’re warmer than me, probably late April, early May.
If the feeder itself has a lot of red on it, they’ll find it! If the container is clear, make sure you at least start out with the red-colored liquid food for them, then you can switch to the homemade stuff once they know where your feeder is. (Homemade: Four cups water, 1 cup sugar. Heat through until all of the sugar is dissolved. Cool. Keep any extra in the fridge.)
Always keep the feeder filled and scrupulously clean. :)
Good information here on their migration and habits:
