Any Chinese ming aralia experts? One of mine is a pseudo-bonsai that has been in good health until the last couple of weeks. There is newer growth on it that is a healthy green and of good firmness. The older, larger growth, however, is weakening, drooping, and yellowing. Is this a replacement of growth or a symptom of something else? It is receiving more light because of the season change, but no other changes. Thank you in advance.
