A word of advice from a fellow Minnesotan
....
We put our feeder out in May, and didn't notice any hummers until we hung the thing right smack in front of the window. Well before we saw any, I purchased a bag of mixed hummingbird
flower seeds and planted them. Well the spot I chose didn't get enough light, and are now just starting to
flower. But the hummers came even though I had no
flowers to attract them. I did notice that they would come to our feeder and then zip over to the neighbor's house to feed from the hostas. So I think just having attractive
plants in the area really helped out.
What I'm saying is you could put up a feeder without having to
plant a garden and you would probably still get some. But if you'd rather have a garden, then more power to you
I prefer a feeder cuz the bloom time for some of the
flowers is so short, and this way with a feeder they can eat until they are ready to migrate south.
