Why Do Snake Plant Leaves/fronds Split Vertically?

Question

I have several snake plants that have leaves/fronds that split vertically and was wondering if this was due to lack of humidty or if there was another cause. Thanks in advance.

Answer 1

Yes, it could be low humidity, but none of the plant care articles I referenced said snake plants needed humidity. Have you cut back on water for winter dormancy?
Splitting can also be due to mechanical injury.

You can remove the damaged leaves at the base of the plant.
