You didn't say what kind of soil you're using, how much light it gets or how much water... which would be very helpful to know.

Yes, it's Sansaveria, I believe.

I use just a standard houseplant soil.. I believe it's by Miracle Gro. I water it maybe once every 2 or so weeks. I live in an apartment, and it's in room that doesn't get that much light.. it's a west facing window.

You may be giving the plant too much water at this time of year. I water mine about once a month, they're in south windows. You want to wait til they are very dry then water well. Also you may want to add some perlite into that potting mix...the soil probably isnt draining fast enough. These are pretty forgiving plants! Good luck,

My guess:
Tissues that become brittle and crack and stems that develop hollow sections are often seen together and a sign of a nutrient deficiency. Since the macro-nutrients are mobile in plants (except Ca; and a Ca deficiency would be manifest in newly forming tissues) it's probably a micro-nutrient deficiency, most likely boron - (split leaves are a noted symptom of boron deficiency in many plants).

To correct (but not repair existing damage) use a fertilizer that contains the minor elements or find a supplement manufactured specifically to supply them.

Thanks for the suggestions. I'll give them a try. :)

I'm having the same problem all of a sudden, I just replanted and mixed the m/g potting soil with the cactus soil for draining.

Can you provide an image of the plant and pot, + any watering/fertilizing info that might help with assessment. Your pot does have a drain hole?

I gotta say, this has to be one of the strangest plants in my collection. I don't mess too much with them - very little water and just let them do their thing (whatever that is - never quite been able to figure it out). I recently transplanted mine with mixed results. They basically form rhizomes, if I'm correct, with very shallow root systems - and so those longer stems fall out of the pots really easily when repotting. Unusual plant to say the least.
