Harvesting tobacco is carried out any time from 70 to 130 days after transplanting in the ground. Usually, the flowers are totally removed in advance of harvest to stop the seeds falling and sticking to the leaves.
You can either cut down the entire plant at one time and hang upside down.
Typically, for the home grower, is to remove tobacco leaves at regular intervals (c weekly) from the bottom up as the lower leaves start to change to a paler color.
After the harvest and before drying the leaves, you need to employ one of four methods to cure your tobacco, depending on what type it is and how you intend to use it.
