Drying, Curing & Post-Harvest

This page collects the terms used for the drying, curing and trimming stages that follow the harvest of a herb or medicinal crop. Each entry explains what the step is and where it sits in the sequence.

bucking

The separation of flower heads or leaf from the stems and branches they grew on, done by hand or with a machine that pulls the stem through a plate of graded holes. It is the step between harvest and trimming, or between drying and trimming, depending on how the crop is being handled.

curing

A conditioning period after drying, in which the dried material is held in closed containers or a controlled space so that the moisture remaining inside the tissue redistributes and equalises with the surface. Aroma and texture continue to change during this time. Curing follows drying and works on material that is already largely dry.

dry trim

Trimming carried out after the material has been dried, with the surrounding leaf left in place during drying. The leaf slows moisture loss and shelters the flower heads, but dried tissue is brittle and handling it breaks material away, so the work is slower and produces more fragments than wet trimming does.

drying

The removal of water from harvested plant material until it reaches a stable condition for storage, carried out in a room where temperature, humidity and air movement are controlled. Drying too fast traps moisture inside the tissue and can alter colour and aroma; drying too slowly leaves the material damp long enough for moulds to establish.

manicuring

The final tidying of already trimmed material, removing remaining leaf tips and stem fragments so that each piece has a consistent finished appearance. It is detail work done by hand at the end of processing, and is usually kept separate from bulk trimming because it is slower and judged by eye.

trimming (wet / dry)

The removal of surplus leaf and stem from harvested flower heads or herb material to give a clean finished product. Wet trimming is done immediately after harvest while the material is still turgid; dry trimming is done after the material has dried. The choice affects labour, drying behaviour and final appearance.

wet trim

Trimming carried out straight after harvest, while the plant material still holds its field moisture. Leaves are easier to separate at this stage and the work is faster, but the trimmed material has more exposed surface and less leaf cover, so it loses water more quickly once it goes into the drying room.
