I've written and spoken several times about an experiment from one of my first years of seriously involving myself with plants. That spring, summer and fall, I gathered small sprigs and handfuls of everything that crossed my path that could be used as infusions. You may have many things that are completely different from what I gathered.
First they were thrown into a large market type basket (except roots or berries which should dry separately), and gently tossed every day when I walked past. After a week, I switched to a second basket while the first basket finished drying. Once dry, they went into a gallon jar.
Fruits like blueberries, currants, or raspberries are delicious, but after they are dried, cut them into smallish pieces.
Over the winter, use that jar up. No two cups/brews out of the jar will be the same.
Get ready now, and start thinking about this so you're prepared. Keep a basket in the car. It's one of my favorite things to do.
