I have a Euphorbia Trigonas that is approximately 7 feet tall. Recently, it has begun to have a brownish scale on the stalks. Have I over watered or under watered. This plant was a gift and I hate to lose it. Thank you in advance
please post some pics of the problem area...hard to give advice when not sure if the problem is :) you could be dealing with water-related issue or it could be some kind of infestation.
