Q.Dying houseplant
I recently decided to transfer one of my houseplants (I think it’s called a dragon tree) to a larger plant pot. Two weeks later it seems to be ailing at a terrifying rate. The stems, which were at one point thick and almost wooden, are withering rapidly and it’s losing a large amount of leaves every day. I’ve noticed that the soil has remained very damp for a while since repotting the plant. Could it potentially be a case of overwatering? Is there anything I can do to salvage it?

It is important to only go up 1" in pot size when repotting your Dracaena Plant.
Though the soil should be moist, it should never be soggy. Too large of a pot can lead to overwatering and root rot.
You can lift the plant and replace the soil. If you can, you can reduce the pot size.
If the roots are black or dark and mushy, you can trim those away.
