Whenever I visit my parents I help them with their pruning. Ok, to be honest I wander around their garden and snip a few bay leaves here and a handful of rosemary there, nothing they would miss but great for our grocery budget. I also trim the herbs we grow in our garden and out on the verge to keep them bushy and productive. Of course I have to do something with all these harvested herbs and a great way to preserve them is by drying.
To dry your herbs they must be free of dirt so give them a good wash then hang up in a warm dry spot. Make sure they are out of direct sunlight to preserve their colour and once dry take them down and store in an airtight container. I hang mine from the kitchen lights, do whatever works for you.
My sister recently pruned her sage plant and dropped by with an armload of the cuttings. When I had finished drying them I compared their weight with that of a typical dry herb canister from the supermarket and estimated I had saved us more than twenty dollars by taking a few minutes to wash and truss up the excess sage with string. Bargain.
