That is how new plants form. They tunnel under the soil and pop up making a fuller plant.

Just FYI-I think the proper term for it would be a "rhizome"-that's how Sans reproduce (other than through seed). The rhizome grows underground for a bit before emerging as a new snake plant or "pup". They can be quite tough-I've seen pictures where a rhizome has literally torn through the side of a plastic pot because there was no room left inside. xD

If you do repot, I would do a full repot (removing all the old soil)-even if it is fast draining it will eventually decompose and break down into smaller and smaller particles, suffocating the roots. I would either use 5:1:1 or a 50/50 mixture of potting soil and perlite.

Lovely plant!

Thank you everyone for your kind replies!

So should I leave it at the bottom of the new pot when repotting (like it is at the moment) or should I place it closer to the surface?

@goldstar - thank you for your suggestion. I'm curious to find out what would make you chose a 5-1-1 mix or 50/50 soil perlite mix for this plant rather than a gritty mix?

Nothing in terms of the plant itself-it's just that the materials for 5:1:1 are easier to find than what's needed for the gritty mix. Same with the 50/50-very easy to find and mix. It's perfectly fine to use gritty for Sansevieria.

I would just leave it where it is currently-if it wants to grow upwards it should do so by itself.

Thank you very much for clarifying, it makes sense :-) And oh that I agree, the gritty mix ingredients can be hard to find, especially in Canada lol.. But I didn't give up the hunt lol and many moons later I finally got all the ingredients for both 5-1-1 and gritty mixes :-)

Happy growing y'all and thanks again for your help :-)

to me, it doesn't matter what medium you place this plant in particular in. As mentioned this plant is pretty hard to kill. Its very hardy and thrives well in ordinary potting soil. My no-green thumb friend has one over 5 feet all and flowering. It's grown in loamy soil back in the tropics.
