The best advice that someone can get when they are worried about their sansevieria is to do nothing. Don't water it, don't fertilize it, nothing.

Make sure that the plant is warm and in bright light. Wait. See what happens. Sansevieria will usually show signs that they need to be watered (the leaves wrinkle on mine all the time when I forget to water).

You could post additional information:
How large a pot is it in
How many plant sare in the pot
Where is the plant located? Temperature? Light?
Has the plant been moved recently?
How often do you water it?
How long have you been taking care of it?
When was it last repotted?
do you have photos you could show us?

All of this information would probably make me advise you to do nothing but keep it warm and in bright light.

I've had this plant for 30 years. I neglected it for many many years. About a year ago I gave it more attention. repotted it, removed dead leaves. It's in a 10 inch pot.
There's over 12 plants in the pot. It's sitting in a southern window. The room is warm It's sitting about a foot back from a radiator. It's been there since October. My son may have been able to post a picture in the gallery. Should I wait at least 2 weeks until I water it again. When I do water it, should I give it a really good drink Thanks alot Joe DeRosa-I figured I would get a response from you. Diane 'hoping to make my plants happy' Skinner

I think Joe has given the exact right diagnosis. Sounds like everything is normal.

These plants can start looking very ill, all at once. They can also look that ill for years, and survive just fine.

I would check to make sure water isn't backing up, or sitting anywhere in the pot, or drainage tray, and that the plant isn't staying wet for long periods of time.

It may not look it's absolute tip top for a while, but it should survive. They can take being unpotted, sitting in water for months, then going dry for months. They will never look like prize winning specimens after that, but life goes on, and they reproduce the best looking kids...

Is the plant possibly too close to the heat source?

I'll keep my eyes open for photos to help diagnose your problem.
