I had a dracaena that looked sick. It's stem was tilted and its roots were coming to the surface. I cut its stem into 4 pieces then pulled it out of the pot. The soil looked very bad, with lots of pieces of Styrofoam. It was also very porous and dry (difficult to describe). I put the stem cuts in water and then pulled the remaining plant out of the soil, with some of the root system and put it in another pot with new soil.
Now for that plant I had enough stems cuts so didn't care if the "resoiling" would kill the plant but I'm wondering if you can do this for other plants. Googling the word doesn't yield much info. I have a croton whose roots have filled up the pot and I'm wondering if the soil has been depleted and so if repotting alone would be enough.
