Q

My newly sprouted green bean plants are getting small to medium holes in the leaves. Could this be from pests or the heavy rain in East Millcreek?

Answer(s)

A

The holes in your bean plants could be from insects or rain or both.  Newly sprouted leaves are especially tender and when we receive heavy rain they can be damaged quite easily.  If the damage was from the rain the newest leaves that emerge should not have any holes, if you see holes on new leaves produced after the rain start looking for insects that may be feeding on your plants.  If it is insect damage and once the insect has been identified you can then choose an appropriate control method.  Below is a link specifically on growing beans that has more information.
