@Box90 good collection.
Careful having too many rocks around your Plumeria, I heard that if it gets too hot, it might burn the base of your plumeria stems. (not sure how hot it will be in NY on summer time).
Also, our moderator, Hetty, always advices everyone to fill the pots up to the top, with dirt since. This will help minimize or prevent burning the base of your plumeria.
