Just noticed there's bees coming and going from a crack in the stonework on one of my raised planters.
And now I've ended up learning about mason bees.
I'll probably wait until September/October when they start to die off, make sure the wall is stable, and leave some cracks for the bees.
I mean, it beats them building a nest in the house.
@renbymon I'm not even sure I'll get rid of the nest, I'm all for a new colony reusing the nest next year.
I'm just not going to rebuild the brick fence pillar until they're gone. :)
