Why are some of my cucumbers misshapen?

Question:

Why are some of my cucumbers misshapen?

Answer:

Poorly-shaped fruit are usually the result of poor pollination.  Poor pollination may be due to cool, wet weather and improperly applied insecticides that limit bee activity.  When insecticides are necessary, select an insecticide with a low toxicity to bees and apply it early in the morning or late in the evening to reduce the risk to bees.
