I have a plant that is on its third year. It was a cutting from a friend’s tree (plant growing in ground to over top of roof and at least 4 ft wide.). It was at least 4 ft tall with a “y” trunk and 3 shoots off y. Each branch was at least 2 ft tall. This year, 3rd yr, it started flowering. Then one of the other branches started growing a flower stem. Then the plant lost strength and the branches feel weak. They still look good green, not shriveled, just slightly limp and, therefore, we had to brace tree. Is this normal when they bloom? Is there something we should look for?
Plumeria have some specific watering and fertilizer needs during their active growth period.
