Pests in Gardens and Landscapes

Blossom drop

Blossoms that wilt and fall off the plant before setting fruit may be affected by a number of factors. For some plants, such as cucurbits, the flowers appearing first are male, which naturally drop. If later fruiting flowers drop in large numbers, it may be due to insufficient pollination. Other factors involved may be extremely high or low temperatures, insufficient soil moisture, or smog.
