Care
Watering
Keep the soil regularly moist during growth, especially in dry periods. Deep weekly watering is ideal to promote root development. Avoid excess water in winter which could cause the root to rot in the ground.
Exposure
Parsnip prefers a location in full sun for good photosynthesis and better sugar content. At least 6 hours of direct sunlight per day is recommended. In very hot climates, light afternoon shade can be beneficial.
Soil Preparation
Enrich the soil with well-decomposed compost before planting. Parsnip requires deep soil (at least 30 cm) and loose texture so the root develops without forking. Avoid compacted or stony soils which deform the root.
Fertilization
Apply balanced fertilizer at sowing time. Avoid excess nitrogen which favors foliage at the expense of the root. Moderate potassium helps improve storage and flavor of the vegetable.
Foliage Management
No pruning is necessary; parsnip grows naturally in a balanced way. Simply remove diseased or damaged leaves. Leave the foliage in place until harvest to nourish the root.
Sanitary Prevention
Parsnip can be affected by rust, especially in humid climates; promote good air circulation. Carrot flies and aphids are the main pests; practice crop rotation. Good garden hygiene and weed removal reduce problems.
Did you know?
Parsnip was one of the most cultivated vegetables in Europe before the arrival of the potato in the 16th century. In the Middle Ages, it was even used as a sweetening syrup before sugar cane became widespread. Its dramatic decline after the introduction of the potato makes it a forgotten vegetable that contemporary gardens are enthusiastically rediscovering.
Where to buy it
Plant in spring or early autumn, avoiding spells of intense heat. Pick a plant with healthy foliage and roots that are not exposed. Best time: March, April, May, September.
