Hi, About 3 months ago I noticed my Thai constellation had developed severe root all the roots, aerial nodes were lost and part of the stem. I am thrilled she has began growing new roots. However, I’m concerned that the new leave which should emerge from the petiole was also damaged with root rot. If a new leaf doesn’t successfully shot from the only leaf with a petiole will it ever grow new leaves. Your opinions would be greatly appreciated
There does not appear to be any rot in the new growth. I'm not aware of any preventive measures other than providing the plant with a proper growing medium. There's much information in the following document: Monstera deliciosa Liebm., Monstera deliciosa, Exotic Rainforest rare tropical plants. There's a suggested growing medium near the end.
Spraying the roots (and whole plant) in a solution of water and 15 to 20% household bleach, then rinsing that off and planting might be helpful in getting rid of the pathogen.
