Turnip plants are a cool season vegetable that grow as a root crop. They are biennial plants, meaning they take two years to complete their life cycle. The turnip plant has a thick, edible root and broad, green, edible leaves. The root is typically white with a purple or red top. The leaves are smooth and lobed, and are typically eaten cooked. Turnip plants prefer full sun and moist, well-drained soil. They are easy to grow, and can be harvested in as little as 40 days.
Planning Your Garden With Turnips

Some plants require more water than others, while other plants require dry soil. At the same time, some plants prefer full sun, and other plants need the shade to survive.
By studying what each plant requires and planning ahead where all of your plants will grow best, you can optimize your garden space.
