You need to give us more than that. What is it potted in? Does the pot have drainage? What kind of soil do you use? how often do you water it? what kind of light does it get? It would be helpful if you posted a closer picture of the pot and soil.

Heh, alright. I didn't know how much detail would be needed, as it's always been a very easy plant before this.

The "pot" is a bamboo mug that's cracked from our dry weather, so it's got plenty of drainage (and a little saucer under it). I think the medium is a mixture of potting soil and scoria, but it's been a few years, so not 100% sure on that.

We water it once or twice a month. It gets almost no natural light (but has always been happy with that before).

It's been living in that spot for... yeesh, probably about two and a half years now.

I spose I can try that... the last time I tried to repot one of these, though, it died a horrible death, so I've been avoiding that. :P

Any thoughts on medium — potting soil / scoria mix, or something else?

Plant looks good to me. You got to expect some leaves to die out. You can always remove the dead portions or the entire leaf. During my winter rest I get a lot of leaves die back. Come late spring, when outside and sunny and all the water they want, they spring right back better than ever.

As per potting mix. It varies as per how you personally grow them. Myself, I use a coarse mix with about 20% potting soil. I use a lot of poultry grit which is granite chips. Most here use cactus mix with 50% perlite.

Thanks, Stush. I've never had any leaves die that I noticed, which is why I got concerned.

> when outside and sunny and all the water they want, they spring right back better than ever.

Are you saying I should be putting it outside and watering it more during the late spring and summer?

Depends, here in Pittsburgh area, they love it. Tiffany in zone 8 plants her's in the ground and they grow substantially. Of course she then has to dig them up and bring them inside. Like Mike said in another post, you must let them get used to direct sun or they will burn. I let mine get direct morning sun only. They seem to love bright shade. I mostly have Sans. trifasciata. Some of the hard leaf types love direct full sun. From what I can see, yours looks like S. trifasciata.

Your plant is self pruning itself because it is lacking something it needs/wants. Sansevierias don't have roots like most plants. They have rhizomes which in turn store food and moisture for growth and flowering. The rhizomes have roots which bring "food" to the rhizome.

From your description and pictures, I would guess your plant does not get the moisture, sunlight, and maybe even nutrients (from fertilizers) it needs to grow and flower. I think you need a better potting mix, better light, and maybe more frequent watering - especially as Summer approaches.

Good advise above but I must add, Do Not Fertilize until growing season when plant begins to grow and then only very lightly. Fertilizer can do more harm than good when plant is in it's dormant stage.
