Recently repotted this monstera. Old and well established. Had been pretty happy prior to this, but was way outgrowing old pot. I mixed miracle gro (mistake) soil with permite and repotted into plastic pot (mistake 2).
All the roots are basically gone. 😭
Question now is do I repot the bases; they look kind of brown - got a terra cotta pot and cactus mix soil with more perlite to add.
Or do I cut bases and old mostly dead roots try to water propagate? If I do, should I cut them shorter? How much should I cut off?
The old canes are pretty long, maybe 2-4 feet. There's two more larger canes I'm about to dig up as well.
I'm heartbroken as she was doing so well before this and I should have really checked for rot sooner (repotted about 1 month ago)


I also did cut off four yellowed leaves. But unsure if I need to sacrifice more. Really at my wits end over this, but trying to be proactive as crying is not helping her.
I've looked through so many other posts, but most are younger plants with less growth and I am truly at a loss.

Have included photos of roots, one cane I've cut, and the largest cane to get an idea of where to cut if needed for water propagation. Really have no idea how long I can leave the cane and still grow roots - ideally wouldn't lose too much height but that's obviously the lesser concern at there moment vs the whole plant just dying.

Thanks In advance for any help!

When you transplanted your Monstera in a larger container you raised the water volume in the roots. The extra amount of soil holds more water than the plant can process between waterings. The result is suffocation from lack of oxygen and dieing roots.

I would put the roots in a smaller container that would dry out in a weeks time. That way the roots can have "wet to dry: cycles that is necessary for good plant health.,

You can propagate your Monstera by stem cuttings. Cuttings should be taken just after a leaf node, removing the bottom-most leaves. Then root the cuttings in water for a few weeks and transplant to a pot or partially bury the cuttings directly in the soil. You should be able to get something from the plant to root and regrow. Good luck.

Contrary to conventional wisdom, older indoor plants rarely if ever need repotting. Their roots settle in and may actually shrink back in size. Occasional fertilizing can easily restore the loss of any nutrients. It wasn't the plastic pot or the potting mix that you used that caused the problem. It was the decision to repot in the first place.

There is not enough health left in the original root system to attempt saving it. Take some short stem cuttings with just one or two leaves on each and propagate them. Discard the rest.

Thanks! I am really hopeful the whole plant is not a loss bc that would be devastating. I realize now the mix of bad soil plus too large of a plastic pot was a recipe for disaster. I'm going to do a few cuttings and see if any of the old vines will survive.

Thanks for your reply, although rough to read. I think from now on I'll hold off on repotting any plants, although I've never had this kind of disaster happen before. Not excited about starting over with this lady, but what can you do?
