If you want to grow long and tapering parsnips you will need a deep, stone free soil, which has been well manured for a previous crop. Any reasonable soil in sun or light shade will grow a good crop. Dig deeply in autumn or early winter and refrain from adding any fresh manure or compost. Break down clods and rake in Growmore fertiliser when preparing the seedbed.
Thin out crops when they reach 1” tall and throw thinnings away. Hoe regularly to keep down weeds. Take care – never touch the crowns of the developing plants. The crop requires very little attention and is not usually attacked by pests. The soil should not be allowed to dry out, and it will be necessary to water during prolonged periods of dry weather.
The roots are ready for harvesting when the foliage begins to die down in autumn. It is claimed that the flavour is enhanced after the first frosts. Lift the crop as required, using a fork to loosen the soil. Leave the remainder in the soil for later harvesting.
