What is Parsnip Canker?
Parsnips are prone to canker, a spore driven fungal disease that causes the roots to rot. This starts to happen as cooler, damper and windier weather comes in over the autumn. Canker is normally seen in the crown/shoulder of the parsnip, although you may see signs of it on foliage too (it’ll look a lot like leaf spot). The root will develop orange/brown coloured patches where it will start to rot.
- Practice crop rotation
- Space plants a little further apart, 40-50cm, if your plot is prone to canker
- Earth up your parsnips by pulling a little soil up around the shoulder of the roots so that the crown is not exposed.
