Generally, the meat needs to be pruned before it is put into the pot, and some old roots and bad roots beside should be pruned, so as to facilitate the later growth. It's a very important step to dry the roots.
The specific time to air it is determined by the wound healing. Normally, it is placed in a cool and well ventilated place for half a day, and it is OK to see the wound healing. If the healing is not good, you can extend the time, and then air for half a day, it will not have any impact on the survival. One careless root repair is too heavy, resulting in some big wounds, so we can't judge according to this time. We need to air it for two to three days, mainly depending on the condition of the wound
