Bouganvillia ( not sure of the spelling)
It is in a hanging pot. Last year it bloomed all summer. Since it was 2 years old it was root bound, so I put it in a bigger pot. This year it has a lot of growth but no flowers. What do you think the problem is?
This is a tropical plant. When the plant is overwintered it can take a while for rebloom the following season. You will have to focus on proper care. Make sure it is located in full sun and they are heavy feeders. Do not overwater.
