Offenham’ A standard medium-sized parsnip. Broad-shouldered and recommended for shallow
‘The Student’ Medium-sized. Thick tapering. Excellent flavour.
‘Avonresister’ A small neat parsnip, much less subject to parsnip canker than many other varieties.
Site and Soil
All soils will produce a worthwhile crop, but for optimum cropping, soils which have been well dug in the autumn and have been enriched with rotted organic matter from the previous crop are recommended.
Seed can either be sown during March or May in drills 30 cm (12 inch) apart and 12 mm (½ inch) deep.
When thehave germinated and are large enough to handle, thin them, leaving the plants 15 cm (6 inch) apart. Hoe regularly, avoiding damaging the developing plant.
Roots are lifted as reguired, but reserve supplies should be stored temporarily when severe frost threatens. Lift and clamp allbefore new growth starts in March.
Pests and Diseases
Canker Shows as rusty-brown markings on the root. This is a complex disease involving three main types of fungus:
i) black canker
ii) purple canker
iii) orange-brown canker.
There are no effective control measures
crop rotation can help. Avonresister’ is resistant to the most common fungus disease. Use a long rotation.
