Blossom drop is the loss of flowers. This is usually preceded by the yellowing of the pedicel. A tomato flower has both male (stamens) and female (pistil) parts within the same flower. The yellow stamens wrap around the greenish pistil in the center of the flower. Under proper conditions, pollen from stamens transfers to the sticky stigma or tip of the pistil. This transfer requires a jarring wind or a flick of the finger. Without pollination, which stimulates fruit set, the flower withers and dies?
