Common Pea Plant Problems

Updated April 17, 2017

If you grow peas, you already know they are among the easiest vegetables to grow. However, they have three distinct problems, and if you end up with those problems, you will have a hard time growing peas as you would like to. Dealing with these pea plant problems can help you have a stronger garden and a better yield for your crop.

Over/Under Watering

Over- or under-watering is the most common problem with pea plants. You can tell if your plants are over-watered because they will start to look mushy around the root areas, and will eventually pull away from the dirt entirely. Over-watered pea plants will be limp and dark green. You can tell whether your pea plants are under- watered because they will start to turn yellow at the edges and will look wilted. Organising your water system and making sure that the pea plants are getting the right amount of water will fix both of these problems.

Root Rot

Root rot causes the leaves to turn yellow and brown, regardless of the amount of water you give them. It is caused by a fungus in the soil, and there isn't anything you can do to save the particular crop of peas. If your pea plants turn yellow and brown, and you pull them up and the roots look mushy and sick looking, you can tell that you have had root rot. The only way to get rid of it is to put your peas on a five year rotation and not plant peas in the same place for five years, until you can be sure that the fungus is gone.

Wilt Disease

Wilt disease is similar to root rot in that it is caused by a fungus. Like root rot, there is no magic cure for wilt disease. You will know it is wilt disease when your pea plants have wilted, and you pull them up and the roots still look regular and healthy. Like root rot, you can only get rid of wilt disease by planting your peas in a different place for five years, and allowing the soil to rid itself of the fungus.
