Hydrangea macrophyllas in your zone 7B can fail to bloom for various reasons: unusually cold winters; some cultivars are more sensitive to winter/frost: florist hydrangeas, variegated cultivars; some of the Teller Hybrids; the plant breaks dormancy and temperatures suddenly crash (common in Atlanta in February or early March; too much nitrogen rich fertilizer; fertilizing too late in the growing season, which keeps the plant in ‘grow mode’ just as early frosts arrive and kill flower buds (your last fertilizer application should occur 3 months before your average date of first frost: the average date falls on weeks 3-4 of October so your last application should occur on weeks 3-4 of July); improper pruning (hydrangeas that bloom on old wood -if they need pruning for some unusual reason- should be pruned soon after the plant stops opening more new blooms in spring. If the hydrangea is a rebloomer, its new spring stems should not be pruned at all. Watch out for pests that nibble on the flower buds (deer, squirrels and bunnies). Very dense shade may reduce blooms. Since flower buds for spring 2023 were created in summer 2022, diseases present in the summer of 2022 or inconsistent watering at that time could have killed spring 2023 flower buds.
