Placement and use
Place parsnips in a bed where the soil can be worked deeply and where a fork can be inserted beside each root at harvest. Sow directly in place; moving young plants can disrupt the developing taproot. A straight row or a short block beside a path makes thinning, shallow weeding, watering, and later digging much easier. Keep the planting away from fennel, and use nearby beans, peas, radishes, garlic, onions, or lettuce only where their own timing leaves the parsnip row accessible.[1]
