I am looking for advice on how to ensure that my 12 year old R. kesangiae continues to thrive. Its basic shape is that of a Y, with the vertical trunk 18" high and the two branches about 14" long. The two branches are equally developed. This year it's leaves are larger than in years past and currently (Mar 31/21) the largest leaf is 21" long. My concern is that, as it continues to grow, the weight of the enormous leaves will tear the branch off the junction with the trunk. Should I remove one of the branches? Should I stop worrying and let it continue to grow? Thanks in advance for any suggestions you may have.
