I was looking for some information about what bees forage on this time of year and found this site. The interactive map is great, you can click on your state for specifics plant/tree info.
It's a great map, however I think blooming seasons are probably inaccurate (for Ohio anyway) because it's been so dry. My bees are finding food somewhere but how long will that last is unknown. Just in case...we have a great big patch of sweet clover that keeps blooming. So I've been keeping that area watered, otherwise it will get burned up like our grass.
Hope everyone is having a great summer.
