The plant genus parsnips encompasses biennial herbs known for their parsnip-like root vegetables. Adequate care involves full sun exposure and regular watering to keep the soil moist but well-drained. Parsnips thrives in a temperate climate, preferring cooler temperatures, and soil that is deep, fertile, and slightly sandy. Gardeners may encounter leaf spot, root rot, and pests like the carrot fly. Seasonally, parsnips requires sowing in spring, reduced watering in winter, and frost protection to ensure biennial growth.
