Thank you very much for your help. I reduced watering and moved the plant in a sunnier position that receives more light all day long as you advised. I waited more than 2 months to see if it would go better. The results: top shoots of the main trunk keep rotting. The lateral shoots that start from the base were clearly improved. Your help was great, the problem was not solved 100% though. Thank you again for your help. I hope I can keep my plant alive.
