Out of six night bloomers usually at least three have blooms every night. My red flare usually has two or three blooms a night and Anteres has between two and five blooms a night. I also have Texas shell pink, Rosa De La Noche, Mrs. George Hitchcock, and a unknown/unnamed white. They usually only have one maybe two blooms a night and not every night. They do need a lot of fert. I feed every three to four weeks. If you start seeing yellowing leaves and the size of the plant starts looking like it's getting smaller, then your waiting to long between feedings. I also notice your in New jersey, they will have to be brought in for winter. I usually take the bulb/tuber out and place it in a cool dark area but don't let the bulb dry out and don't let the water get to fowl. Come spring replant and off it will go again. If you see nannies separate and plant in a separate pot. to many baby lilies and the parent plant won't bloom nearly as much.
