Pests in Gardens and Landscapes
Lack of pollination
Poor pollination may be caused by a number of factors. Bees generally pollinate flowers of many vegetable
plants. Rain, low light, or cold and hot temperatures can limit bee activity. Planting varieties not suited
for your area or planting at the wrong time may also contribute to poor pollination. Depending on the
vegetable, poorly pollinated plants may have fruit of normal color but are small and appear flat. Some
fruit may appear shriveled or turn brown. Fruit that normally has seeds may have few or no seeds inside.
Corn lacking in pollination may have shriveled or incompletely developed kernels. In other cases, no fruit
sets at all.
