Harvesting basics Pick em, don't strip em

No matter how you intend to use your herbs after harvesting a few basic rules still apply.
# Tree Leaves should be gathered before Midsummer. After that, the percentage of natural insecticides in the leaves are too high.
# Leaves are at their most fragrant, and richest in volatile oils, before any flowers have opened. The exceptions to this are: borage, coltsfoot, cowsslip, fenugreek, lungwort and sweet violet; they should be gathered after flowering. Rosemary can be gathered at any stage. Gather early on a dry day, after the dew has dried but before the sun is too strong. Dry in a shady, cool, and airy place away from any strong heat sources. Avoid steamy places such as kitchens or bathrooms. Once dry, crumble the leaves and discard large pieces of stem, store them in a lidded glass or ceramic jar away from the light.
# Flowers are gathered on a dry day when the flowers first begin to open. They should always be dried in the shade. Carefully cut each flower head off the stalk, remove any insects or dirt, and place on a paper lined tray. Leave to dry in a warm place and turn regularly Small flowers such as lavender, are dried in the same way as seeds - by hanging them upside down and collecting the flowers in a paper bag. Once dried, store in a lidded glass or ceramic jar. Dark colored jars are best because they keep out the light. Calendula petals should be separated from the center part once they are dry.
# Roots are generally gathered in the fall after the plant has begun to die back. The exception to this is dandelion roots, they should be gathered in the early spring. Wash them thoroughly to remove any dirt. Chop large roots into smaller pieces to speed up the drying process. Spread the root pieces on a paper lined tray. Preheat the oven and turn it off. Place the trays inside with the door ajar for 3-6 hours (depending on how large the pieces are). Transfer the trays to a warm room away from the sun until completely dry. Store in airtight containers away from the light. Check periodically as dried roots have a tendency to reabsorb moisture from the air, discard any pieces that become soft.
# Seeds should be gathered as they ripen, usually in the fall. Seed heads should be hung to dry inside a paper bag. Don't use plastic as any condensation that gathers could lead to mildew and cause the seeds to rot. Once dry separate the seeds from their cases and store in the same manner as leaves and flowers.
# Berries are harvested when they are just ripe, usually in the early fall, before they have become too soft to dry effectively. Spread on paper lined trays, discard any that show signs of mold. Preheat your oven and then turn it off. Place the trays of berries inside with the door ajar for 3-4 hours. Transfer the trays to a warm, airy spot, away from the sun until completely dry. Turn regularly to ensure even drying.
# Tree barks generally contain the desired medicinal properties in the soft inner layer (cambium) between the sapwood and the dead outer bark, or the bark of the root. Bark should be harvested in the autumn when the sap is falling. This will avoid damaging the tree too much. Never remove all the bark or even a strip of bark completely surrounding the tree. Dust or wipe bark to remove moss or insects. Break into small pieces (about 1-2 inches). Spread the bark on paper lined trays and leave to dry in a warm, airy room away from the sun.
