There are a couple of varieties of Sans. which normally grow that way (splayed outward as you describe rather their leaves standing straight up & down). Without knowing which you have, I can't say if that's normal growth for it or not.

If the leaves feel firm & sturdy to the touch, that's a good thing, if the leaves are floppy or wobbly at their base, that may indicate a problem.

A picture would help for sure.

I suppose your Sans has a lack of light, and root damage due to too much water. Show us a pic PLZ

Or too much water and shade perhaps.

San. sp. kirkii pulchra leaves grow 4ft long a drop to the sides ending up 8 ft across. I have 259 sp. not all of them grow neatly, and it has nothing to do with water or light. Its in their DNA why species of some San. can grow 8 ft tall, some only 8" tall, so we can't tell you want you what you are doing wrong, unless you provide a picture, or the name of the species, what soil mix you are using, how much light it is getting, water,soil fertilizer, air. I am being sincere about this we all want to help.

Hi Norma,

It's Kirkii v. pulcher I had in mind when I answered that depending on the type of Sans. this could be normal growth for it. I no longer grow this one, but have in the past, so that's why I said that.

It appears the person has not been back since they posted, or at least they haven't responded

Sans. kirkii has many varieties some will flop sideways other do not.

Regarding leaves that should be upright and is now fallen over. this may be due to having root rots or salt in soil build up. Try changing the media and stop using fertilizers high in salts. Be sure to water and allow drainage to occur when water drains freely.
Propping up the leaves with a stick and wire also can help keep your plant upright.
