How to Grow Rutabaga in Your Canadian Garden: A Hearty Root Vegetable

Rutabaga, also known as swede or yellow turnip, is a cool-season root crop known for its nutty, sweet flavor and excellent storage ability. It’s an ideal vegetable for northern gardeners looking for a reliable fall and winter food source.

Why Grow Rutabaga?

  • Cold-hardy: Thrives in cool temperatures and improves in flavor after frost.

  • Long storage: Keeps for months in root cellars or refrigerators.

  • Nutritious: High in fiber, vitamin C, and potassium.

  • Spacing:

    • In Rows: 6 inches apart.

Late planting ensures roots mature in cool fall weather, enhancing flavor.

  • Refrigerate in plastic bags for up to 3 months.

Container Growing
