Name the intended result
Fresh stems, dried flowers, and material for distillation are different harvest goals. A calendar date alone cannot describe readiness. Note the cultivar and flower stage, and discuss the intended use before deciding when to cut.
Prepare the record first
A labeled container and a notebook prevent small batches from becoming anonymous. Give each harvest a batch name. Record the date, cultivar, part of the plant collected, weather, intended use, and any changes made during handling.
For a small drying trial
Herbs dry best with good air circulation, protected from direct sun. Keep small labeled batches separate so their appearance and aroma can be compared. Material should be thoroughly dry before storage; inspect it and discard anything moldy.
Compare one change at a time
When trying a different harvest stage or drying arrangement, keep the other conditions as consistent as possible. Record what changed and what was observed. A useful record explains the process, not just whether the result was liked.
