Parsnips do best in an open sunny site with free-draining, well-worked soil with no stones. Overly fertile soil can cause the roots to fork, so sow them where you haven't dug in any compost or manure in the last year. Sow seeds directly into the soil from mid-spring, after the soil has warmed up.

How to prevent black canker on parsnips?
Hilling up parsnip roots will reduce damage from black canker. Keeping the shoulders covered throughout the growing season by routinely adding soil to the rows has been shown to lessen the disease’s impact. The soil may protect the roots from inoculum from above-ground infections as well as protect roots from damage and provide better drainage, thwarting the pathogen.
Where are root cankers most prevalent?
Root cankers are most prevalent on the shoulder area , where they will progress from smaller brown areas to large, black superficial lesions. As the disease progresses, the lesions can expand. Secondary infections are the major concern, leading to root rot.
How does chlamydospores spread?
The pathogen overwinters in soil or plant debris as chlamydospores. It can also be spread via wind during the ballistospore phase, but these will rapidly die once in contact with soil organisms (unlike chlamydospores, which can survive in soils for years). I. perplexans causes lesions on parsnip roots, crowns and shoulders as well as orange- or brown-colored lesions on the above-ground parts of the plant, and can invade lateral roots too. Infections on the leaves are thought to provide fresh inoculant for root canker development. Superficial damage to the roots, from insects or other disease-causing organisms, is thought to pre-dispose roots to canker. Damaged areas allow the fungus to enter the root, and the cankers caused by the fungus in turn allow further secondary infections to occur.
Can carrot rust cause canker?
Carrot rust fly damage is thought to be a primary predisposing factor to Itersonilia canker. The carrot rust fly larvae, which are yellowish, legless maggots which mature into black flies noted for largish, yellow eyes and clear wings, cause damage to the roots. The larvae burrow into root tissue, leaving channels. Preventing any root damage from these or other insects, other microbes or mechanical harm can reduce I. perplexans infection.

Is a parsnip a pathogen?
The pathogen is widespread as a leaf surface saprophyte (non-pathogen) on umbelliferous crops and members of the Compositeae. The fungus overwinters in infected parsnip roots or as chlamydospores in the soil. Spread within in a field is by windborne spores. New spores produced on foliage fall to the soil and cause root infections. Disease development is enhanced by cool, wet weather.
