The first sign of root-rot disease is yellowing and wilting of the leaves which is rapidly followed by browning and houseplant collapse.
The cause of root-rot disease is a fungal decay due to soggy soil.
Always ensure that the soil for your houseplants is free-draining soil and that the pot you use for your plant has a drainage hole.
This will prevent water from standing too long in the potting mix when you water your plant and thus prevent the soil becoming soggy.
Most houseplants will be killed by root rot disease if the soil remains too wet for too long.
Cacti, Succulents, Begonia, Palms and Saintpaulia are highly susceptible to this disease.
If spotted early, root-rot disease can be treated and the houseplant can be saved.
The best treatment for root-rot disease is through Root Surgery Technique.
Cut away any stems or leaves showing any signs of rot. Cut off brown-black, mushy roots.
Ensure the entire plant is well covered with the fungicidal solution.
Ensure the soil is free-draining and the pot has a drainage hole to prevent the soil from getting soggy.
Do not water the plant again until new growth appears and avoid overwatering and soggy soil thereafter.
Discard the plant and disinfect the pot with a fungicidal solution before re-using it.
