Helping Solitary Bees - will they all nest in flower pots?
Berghill and Jimmy have told us about Leaf-Cutter Bees nesting in their flower pots, as a bit of a nuisance (in the greenhouse I think?).
Turning this around: If solitary bees will nest in flower pots, why am I laboriously making bee houses from bamboo cane, etc?
Does anyone have experience of what flower pots exactly to use, and how to set them up, in order to get solitary bees to nest in them?
