Q.My Mother-in-law tongue plant has vertical splits
I water my plant every month or two and have noticed it has splits in the leaves near the center. What causes this?
Leaf splitting in sanseveria is generally caused by physical damage - usually brushing against the plant, or wrapping it up at some point. Cats and dogs can also cause such damage. It's sometimes hard to pinpoint when damage happens because snake plants don't show the damage right away.
