HI
Plantgirl heres what i know abought it
the Snake
plants also know as mother inlaws toungs. thrive in full sun. they will tolerate low light but color variegations will not be as pronounced. Snake
plants are able to tolerate periods of drought but will not tolerate wet conditions since root rot may occur.it sounds like it may have been in the cold i would cut away all the bad shoots since there already damaged.let the new growth start from there the
plant comes from a rizom witch is a tubber type root system.it should grow back but will be slow as they are a slow
growing plant.hope this helps.your friend in gardening mike57
