Perennial herbs that are not hardy in your region can be overwintered indoors, then brought back outdoors in the spring. For example, in USDA Zones 7 and colder, bring rosemary and lavender plants indoors in late fall. Maintain them in a cool, bright spot over the winter, and move them outdoors again in the spring. In USDA Zones 8 and warmer, rosemary and lavender can be left outdoors year-round.
There’s a solution for dealing with wood screws which have broken off below the surface of the wood. If you don’t want to risk damaging the wood by digging it out, try driving the screw deeper into the wood with a nail set. Then just fill the hole with a wood filler, and drive a new screw next to the broken one.
