This appears to be from overwatering. Treatment from here will be a fungicide.

These plants get a little fussy in container. They will need to dry out pretty thoroughly between each watering, and even let to dry for some portions of the year. This article will offer more information on how to care for these plants indoors:

e it grow back from the roots? or is it too far gone?
Unfortunately, your photos did not come through. I am unable to see the extent of the damage. If there is still some life left to the roots, then it could not hurt to try to revive the plant!

The weather in Idaho has been very cool with a few hot days sprinkled in. 65/40 and one 91 degree day. My licorice plant is blooming and no one here in Idaho can tell me why.
They bloom in June and August, naturally. It may have to do with photoperiodism. I could not find much reference to the subject, however, in some studies it was noted that vegetative growth was more vigorous during shorter daylight periods. Flowering was best achieved with a longer daylight period.
