You've probably discovered that it is just water stressed (wilted). It should come out of it on its own if you didn't damage the roots too badly. To ease the stress, enclose it in a clear plastic bag - maybe even a garbage bag - to keep the humidity high until it rebounds.

What is in a pot does not matter, as long as it's not toxic to the plant in some way, just its' texture & ability to retain moisture & oxygen @ the same time. If it has no inherent fertility, very effective fertilizers exist to serve those needs. I don't doubt you at all. I don't have access to ingredients for that so I can't offer any feedback about it. If buying a bag, I look for cactus/palm soil, but go more by weight over what it says, and look for a broke bag to inspect and make sure there's no peat in it, and hopefully not much perlite. If it's not lightweight for its' size, it's not helping me reduce the weight of larger pots, and probably not going to help with keeping more oxygen in the soil. Digression alert, probably on this whole post... I don't want to be confusing either, and do not offer any of this as a recommendation because it has evolved over quite some time of trial'n'error, and other, personal factors like personal acute dislike of perlite & seeing those little white things in my pots, a lot of reading about roots & microbiology, dislike of spending much $ to have something in a pot in which a plant can grow, realizing that if there is no peat, I can probably keep a plant alive, ...and especially to someone in the middle of a city without a yard. I'll use anything but peat/potting soil, and often add some roughage from compost pile. Dracaenas grow fine in ground dirt from the "good dirt" part of a tended plot, especially if I'm going to repot them often anyway. Fine for smaller plants but way too heavy for a plant of decent size. Since all old "dirt" gets put into flower beds, I don't put anything in pots that I wouldn't put in/on the ground. This is why I quit buying flats of annuals to use in the ground and started putting my house plants instead, because I kept finding styrofoam instead of perlite in the soil of them. I refuse to bury other people's non-biodegradable trash in my yard.

Answered on one of your other threads.

It was hard to dig up to be honest. We finally got the one big root that was holding it in. We didn't break that one but lots of the small roots around it broke off. God I'm praying for doesn't die!
