Hi plant friends! My sister has a red aglaonema plant that didn’t look like it was doing well so I took a look at the root ball and it was mostly root rot. I haven’t had success propagating these to grow roots again. Does anyone have advice? I rinsed off the dirt and took off the rotted roots, and then soaked it in a hydrogen peroxide solution. I will cut off the orange ends to fully get rid of the rot. And then let it callus for 24-48 hours. Am I on the right path? Then what?
