My Sweet Sugar blooms almost all summer, and needs lots of water--outdoors two or three times a week and indoors in the winter twice a week. Outdoors I give it strong morning sun and then bright sun for the rest of the day and indoors it's in a cool west window. Someone once told me in addition to my regular fertilizer to give my plants one tablespoon of epsom salts (magnesium) to one gallon of water once a week for three weeks to enduce flowering. It worked.
