Hello Sir. I have some queries about plant collection and drying processes. 1. Can we pluck leaves and leave the plucked leaves to dried separately? 2. Can we cut the roots and leaves separately and dried and powdered at the same time. 3. How long time we should dry the plant sample in shaded area? 4. After powder prepared, how long time we can use powder to carry various experiments? I request you to please answer my doubts.
