Splitting

This is nearly always caused by sudden wetting of the soil after a prolonged period of relative drought causing the plant's tissues expand too rapidly as it sucks up the water. Cracks may become infected by moulds and will reduce storability.

Symptoms

  • Vertical cracks in roots such as parsnips, carrots and beetroot
  • Splits in the skin of tomatoes
  • Hollow spaces on the insides of potatoes and onions

  • Prevention & control

    • Keep plants well-watered during dry spells - a mulch will help to prevent the soil drying out
    • Keep plants growing strongly as stop and start growth can also cause this problem
    • In tomatoes, harvest in good time (and ripen indoors if necessary) to avoid the cooler, wetter conditions in the autumn
