Hi,
I have 5 plumeria plants that I grew from little sticks and move the pots inside and out every year. Only one has ever bloomed and the blooms were eaten by a green grasshopper! I am not sure what I am doing wrong, they get osmocote every spring, with a top dressing of potting mix with worm droppings mixed in and at least 9 hours of sun evry day when they are outside.
Any suggestions from you northern growers that might help me get these to bloom? Should I be using Epsom salts once a week in addition to the osmocote?
