Hello. I keep finding leaves that look like the attached image on my Snake plant - I think the best description is "wrinkled" (rather than droopy) - they wrinkle and twist and then kind of fall over. I just cut about 8 of them off my snake plant. Any idea what could be causing this? Under or over watering it? The snake plant is about 4 feet tall, I water it very thoroughly about once every 3-4 weeks. Is snipping the leaves with scissors at the base (as close the soil as I can get) a good way to trim? There's obviously still a little stump in the soil that goes down into the roots. Thanks!
