Prairie Petite Lilac
I have a Prairie Petite Lilac (Syringa vulgaris). It is supposed to be 3 to 4 feet tall. The first year after I planted it it grew about an inch and had a few flowers. Since then it has grown over a foot each year, straight up and does not flower. it is now 6 feet tall. It gets about 6 hours of sun from 9:00 am to 3:00 pm. Other than being 6 feet tall and not getting flowers it is a healthy beautiful plant. It is too tall now for the space it is in. What should I do? Should I cut it back? Move it? Feed it? Thanks for your help.

This sounds like the lilac's dwarf qualities are not retained by your plant. It is supposed to sucker, sending up other stems of the same species. If there are other stems arising from the root system, cut back this one tall shoot to a height you wish for the spot.
Or you could move the entire plant to a spot that can handle the plant.
