    It could possibly be a late frost that is interrupting some of your blossoms.

    In my case hydrangeas are influenced.
    In summer, branches produce new buds for the next spring. These buds stay dormant all winter and bloom in spring. If winter temperatures got too cold, or if there is a spring cold snap that kills the buds, non-reblooming Hydrangea macrophylla will not produce flowers that year.

    Perennials like full sun, full shade, a blend, find out which you have and do a little research to make sure they are getting the correct amount of sun.
    If they are getting all they need as far as sun, then try fertilizing, sprinkle a little Epsom salt around the plants, this adds magnesium sulfate to the soil, a nutrient.

    Possibly too much shade . Also if you fertilize w/ a lot of Nitrogen , top growth (foliage) will get all the energy and flowers won't do much . Try more Phosphorus if this is the case . Chance flower buds getting killed by late frost ?

    Are your spring perennials tulips? When they produce only leaves, time to dig them up and plant new ones. Extension gardner said tulips will not produce flowers again, once they start growing only green leaves. I had that happen so now only plant daffodils and hyacinths.

    You should probably move them in direct sunlight. We have a hibiscus that does this because we moved it into a shadier area. Once we moved it back, it finally bloomed!
