Selecting the appropriate sweet potato variety is crucial for success. Different cultivars vary in their taste, texture, and suitability to Queensland’s climate. Here are some popular choices:

Preparing the Soil
Sweet potatoes thrive in well-drained, sandy loam soil with a pH between 6.0 and 6.8. Prior to planting, it is essential to prepare the soil to ensure optimal growth:
1. Tilling: Loosen the soil to a depth of at least 12 inches to facilitate root development.
2. Adding Compost: Incorporate compost or well-rotted manure to enhance soil fertility and drainage.
3. Fertilization: Apply a balanced fertilizer, such as a 10-10-10 blend, according to the manufacturer’s instructions.
Planting Sweet Potato Slips
Sweet potatoes are typically grown from slips, which are young plants produced from the roots of mature sweet potatoes. Here’s how to plant them:
1. Preparing Slips: Select healthy slips that are about 6 inches long with at least three leaves.
2. Spacing: Plant the slips in rows, spacing them 12 to 18 inches apart. Leave 3 to 4 feet between rows.
3. Planting Depth: Plant the slips at a depth of 4 to 6 inches, ensuring that the leaves remain above the soil line.
Watering and Fertilization
Sweet potatoes require regular watering, especially during dry spells. Aim to keep the soil consistently moist but not waterlogged. Fertilize the plants every 4 to 6 weeks with a balanced fertilizer, following the recommended dosage on the product label.
Pest and Disease Management
Sweet potatoes can be susceptible to various pests and diseases. Here are some common issues to watch out for:
- Sweet Potato Weevil: These insects can damage the roots and stems of the plants. Use crop rotation and insecticides to manage the infestation.
- Fungal Diseases: Fungal diseases, such as Fusarium wilt and black rot, can affect sweet potatoes. Use disease-resistant varieties and practice crop rotation to minimize the risk.
Harvesting Sweet Potatoes
Harvesting sweet potatoes typically occurs 100 to 120 days after planting. Here are the steps involved:
1. Checking Maturity: Dig up a few potatoes to check for maturity. The skin should be firm, and the flesh should be fully developed.
2. Digging: Carefully dig around the plants to avoid damaging the potatoes. Use a garden fork to loosen the soil and gently lift the potatoes out.
3. Curing: After harvesting, cure the sweet potatoes in a warm, humid environment for 10 to 14 days to improve their flavor and storage life.
Storing Sweet Potatoes
Store cured sweet potatoes in a cool, dry place with good ventilation. Ideal storage conditions include a temperature between 55°F and 60°F and relative humidity around 85%.
