The idea of growing sweet potatoes in Alberta might seem like a pipe dream, but it’s actually achievable with a little know-how and some strategic planning. This blog post will guide you through the process of cultivating these delicious root vegetables in the unique climate of Alberta, helping you harvest your own sweet potato bounty.
Understanding the Challenge: Alberta’s Climate and Sweet Potatoes
Sweet potatoes thrive in warm, sunny climates with long growing seasons. Alberta, with its shorter summers and cooler temperatures, presents a unique challenge for growing this tropical crop. However, with the right techniques and varieties, you can successfully cultivate sweet potatoes in Alberta.
Choosing the Right Sweet Potato Variety
The key to growing sweet potatoes in Alberta is selecting varieties that are specifically bred for shorter growing seasons and cooler climates. Look for varieties labeled as “northern” or “short-season” sweet potatoes. These varieties mature faster and can tolerate cooler temperatures. Popular options include:
- Beauregard: This variety is known for its vibrant orange flesh and sweet flavor. It’s a good choice for both baking and frying.
- Jewel: This variety offers a vibrant red skin and a sweet, creamy flesh. It’s ideal for baking and roasting.
- Covington: This variety boasts a deep orange flesh and a slightly tangy flavor. It’s a versatile choice for various culinary uses.
Starting with a Head Start: Seed Potatoes vs. Slips
You have two options when it comes to starting your sweet potato plants: seed potatoes or slips.
- Seed Potatoes: Seed potatoes are small, dormant sweet potato tubers that are planted directly into the ground. They require a longer growing season to mature, making them less suitable for Alberta’s climate.
- Slips: Slips are cuttings taken from mature sweet potato plants. They are easier to grow and have a shorter maturity time, making them a better choice for Alberta gardeners.
To obtain slips, you can either purchase them from a local nursery or start them yourself. To start your own slips, plant a sweet potato tuber in a pot filled with potting mix, keeping it moist and warm. After a few weeks, slips will sprout from the tuber, which you can then carefully remove and plant in your garden.
Preparing the Perfect Growing Environment
Sweet potatoes need well-drained, loose soil with a pH of 6.0 to 6.5. Amend your soil with compost or manure to improve its fertility and drainage. Choose a sunny location in your garden that receives at least six hours of direct sunlight per day.
Planting Your Sweet Potato Slips
Once the soil has warmed up to at least 15°C (59°F), you can plant your sweet potato slips. Dig a hole about 10 cm (4 inches) deep and 15 cm (6 inches) wide. Place the slip in the hole, ensuring that the top 2-3 cm (1 inch) of the slip is above the soil line. Gently firm the soil around the slip and water it thoroughly.
Providing the Right Care for Optimal Growth
Sweet potatoes require consistent moisture, so water them regularly, especially during dry periods. Mulching around the plants helps retain moisture and suppress weeds.
Fertilize your sweet potatoes every 4-6 weeks with a balanced fertilizer. You can also use organic fertilizers like compost tea or fish emulsion.
Sweet potatoes benefit from hilling, which involves adding soil around the base of the plant as it grows. This encourages the development of more tubers.
Harvesting Your Sweet Potato Bounty
Sweet potatoes are typically ready for harvest 100-120 days after planting. You can check for maturity by gently pulling on the leaves. If they come out easily, the potatoes are ready.
To harvest, carefully dig around the base of the plant and lift the tubers out of the ground. Handle the potatoes gently to avoid bruising them.
Storing Your Sweet Potato Harvest
Store your harvested sweet potatoes in a cool, dry, and well-ventilated place. They can be stored for several months if kept properly.
