It needs to be watered. Does the pot have a hole in the bottom for draining?

I have never sprayed sansevieria (and I have about 12 or 15). Nancy is right. Water it. Put it in a fast draining mix in a pot that has a drainage hold at the bottom. You can use cactus/succulent soil and sifted perlite 50/50; they are found anywhere, even big-box stores. DON'T over-water. More sans are killed by over-watering than anything else. They can stand a lot of neglect if they are not over-watered and have even modest light.

No hole at the bottom of the pot. Ok i will try to change the pot and soil. Is watering once a month enough? Also are the pictures indicative of lack of water?

manplant69, yes, they are totally dried out. The roots should be white and all of those leaves should be round and plump.

What the nursery sold you was cuttings. They had no roots and that's why he told you to spray them to keep them hydrated. That said, they should have been watered at some point when roots began to appear. Usually after a month or two. Good advise given. Shouldn't have any more problems.

Note; that pot will be quite crowded shortly when pups start to appear and grow larger.
