I repoted this desert rose plant in June 2020. Since then it has grown very tall but the caudex remains the same size. I use a moistur meter and only water it when it is dry ( in red ). It has lost some leaves over the winter ( I live in New York ) but it is still getting taller. It is in a 10 inch pot. Should I repot it into a smaller pot or leave it alone. I am attached photos to show hoe tall and how small the caudex is.
