Anita and I have been thinking about, and designing a Bee Garden; my daughter is close and has about 3 acres, so we are going to keep the bees there instead of at our yard, so this is much better for all involved.
We’ve purchased some bee friendly seeds from Ohio Prairie Nursery, and are figuring out where to put them (www.ohioprairienursery.com); they had some really neat seed packets, endorsed by Ohio State Beekeepers Association and West Virginia Beekeepers; I got a handful of those packets, plus some others that have different blooming periods. This will help in a small way (cause you really need acres and acres of flowers for a colony), but in time, perhaps this can expand.
I’m big on perennials because of lower maintenance, but there are trade-offs with annuals; these mixes have both; hopefully, by the 2nd season, the perennials will be well-established; with more acreage, hopefully we can create a really nice place for both us and the bees.
