Hi all hope everyone is fine and there doing well, just to ask iv been tryn to search on the forum bout my carmona, it is doing good, but just noticed leaves fall off it every other day but its at the parts were there is new shoots and leaves are growing is this normal. and rhanks again for all hep given so far many thanks for all future help.xx sorry and another thing how can you tell how old your tree is.xx

Did you post a picture of your Carmona?

Short answer = no, this is not normal. I have a Carmona and it drops maybe 1 leaf a month. I've had this tree for 3 years now so I know that this is a sign that I probably should have watered it a day or so earlier. However, this is true about my tree and not necessarily the source of your issue.
Pictures of the tree and information about soil, watering, fertilizing and lighting would be needed for further troubleshooting.
