That looks like a Rhyzome. Soon you're going to have a baby Sansevieria growing out of that hole

You could take the plant out of the pot, somehow untangle the rhyzones, and guide them upwards

Oh, those are ryhzones! Should I get a slightly bigger pot since I may have to cut this one if the ryhzone doesn't come out easily? That's so cool that I'm getting a baby or two. Thanks.

I bought a Sans masoniana last year from a local grower. The plant had been pretty neglected and was just left to grow forever in a nursery pot similar to what you show in the photo. One rhizome had grown through one of the bottom holes and a somewhat deformed new leaf eventually emerged from that hole. I cut the whole plant apart (I knew I would do this when I bought it) and made 3 separate plants.

From the photo, yours doesn't look large enough to do that. If it were mine, I would buy a larger plastic pot and repot it. You might aim for a pot 2" larger in diameter and 2-3 inches deeper too. You can cut the existing nursery pot and work around the rhizome so it stays intact. Just repot it and it will eventually grow up and out of the soil. I've done that a couple of times with new rhizomes.

Thanks Robin. Yes, I figured I'd better cut around the rhizome so as not to damage it. Thanks for the specs on what pot size to get. I never repotted a sans before. I know they like to be pot bound but didn't know how much so.

I didn't know that! Thanks Manuel. I ordered the new pot today. Couldn't find anything suitable in the local stores. I'm going to change the soil when I repot it. After reading here on GW I plan on using C/S mix with added pumice and chicken grit but I'm not sure of the ratio? 1/3 of each?

Yes, I think 1/3 each is a good ratio. That's about what I use for the vast majority of my Sans and, so far, it works okay. Sometimes I just use 60% perlite and 40% C/S mix, or 50/50. Manuel is right about pot size. I have found that "potbound" is never a real advantage. I wouldn't go TOO big, but definitely bigger than the current pot -- since it is busting out already. Give its roots room to spread. Keep in mind that C/S soil definitely holds water. Pumice holds a little water too, similar to perlite. Chicken grit does not hold any water. So, a blend should give you good drainage and modest water retention.

Thanks Robin. I also have the large granule perlite but am trying to get away from using that and switch to using pumice because i don't like how perlite filters up to the top of the soil.

Another question. I have a Sans Cylindrica coming in the mail. It's bare root. I never bought a bare root before and am not sure how much to initially water it after I pot it for the first time. Should I wet the mix before potting and then not water for a few days or pot it dry and water thoroughly till water runs through?

When I get a bare rooted Sans, I generally pot it up within a day or so. I figure the trip across the country was hard enough already. I don't wet or water it before planting in a new mix, and I don't water it for several days after planting. If the roots are dry, I will generally dust with root hormone, plant in a mix of C/S soil, perlite (or pumice) and some chicken grit (unless it will make the pot too heavy for me to lift) and -- that's it's new home. Let it rest for 2-4 days before watering, or at least that is what I do. I never wet the mix before potting, and when I water, I water until I see it come out the drainage holes -- not pouring out, just showing that there has been enough watering into the mix. Be careful not to overthink this or fuss too much. Sans always seem to do better with a tiny bit of "neglect."

Thanks Robin. I will do as you suggested. It should arrive today.

Here's photos of my new cylindrica that arrived today. I will have it sitting out for a few days till the grit arrives either Monday or Tuesday. How far apart should I plant them or should they be in a bunch (they came rubber-banned together. I removed the band so they could breathe. There are some nice little rhyzomes starting.

The grit came today so I potted the cylindricas into three little pots (was supposed to have been only two but I missed a leaf so decided to plant it solo. Added some stones to stabilize them.

Had to order more pumice so when it comes in will repot the Masiniana.
