Don't clean your flower beds too soon...
Like all wildlife, pollinators require a home in which to rest, escape the weather, and (most importantly) lay eggs and provision their young. In our desire for tidy lawns, we often inadvertently eliminate suitable shelter and nesting sites for pollinators.
Important nesting sites for bees include patches of bare ground (which allow bees to access underground cavities), logs, stumps, last season’s flower stems, abandoned rodent nests, and untidy corners with taller grass and flowers. Where possible, leave bare patches of ground and dead vegetation standing over the winter until mid-May (by which time the pollinators will have emerged). These practices provide dormant season habitat for pollinators. If you must cut down your perennials in the fall, try to leave them in a pile on your property until mid-May and then remove.
