From the image you sent the plant looks healthy so I am not sure if the blooms fell off from cold temperatures or lack of water or if the plant was just transplanted and the blooms dropped due to transplant shock. How old is the plant? Where do you live? Did you recently fertilize or spray near the plant? The good news is that you may see new buds form as the plant recovers from whatever trauma caused it to drop blooms. Keep growing, Marianne Binetti
