When they get tricked into blooming in the fall, those buds that are opening or partially opening are the ones that were to open in the following spring. So once they open or partially open, they are done and you get no spring bloom.

Some causes of fall blooming include a dry summer and moist fall and/or warmer climates including a warm fall. For some reason, fall blooming is more common in Georgia according to Dr. Sandra McDonald. Plants which are not sufficiently hardened off or are exposed to unseasonable warm spells can start bloom prematurely. These blooms are seldom satisfactory and many times get frozen before opening fully. In any case, the seasonal bloom is lost. Avoid application of nitrogen after late spring, but phosphorus and potassium may be applied during the growing season. Application of nitrogen too late in the season can hinder hardening off in the fall.
