Choosing the Right Variety

Select a soft cooking potato variety that thrives in South African conditions. Popular choices include the BP1 and Up-to-Date (UTD) varieties, both known for their smooth, creamy texture when cooked.

Planting Time

The best time to plant potatoes in South Africa is late winter to early spring (August to September) when the frost risk has diminished. Ensure the soil temperature is around 10°C for optimal growth.

Preparing the Soil

Potatoes prefer well-drained, loose soil rich in organic matter. Prepare the soil by mixing in compost or manure to enhance fertility. Ensure the soil is slightly acidic, with a pH between 5.0 and 6.5.

Planting

Cut seed potatoes into pieces, each with at least one eye (bud). Allow them to dry for a day planting. Plant the pieces about 10cm deep, with the eyes facing up, and space them 30cm apart in rows.

Watering and Maintenance

Potatoes require consistent moisture, especially during the tuber formation stage. Water the plants regularly, ensuring the soil remains moist but not waterlogged.

As the plants grow, mound the soil around the stems to protect the tubers from sunlight.

Harvesting

Soft cooking potatoes are ready to harvest when the plants begin to yellow and die back, usually about 10-12 weeks after planting. Gently dig up the tubers, taking care not to damage them.

Storage

After harvesting, allow the potatoes to cure in a cool, dark place for a few days. Store them in a well-ventilated area, away from direct sunlight, to prevent greening.

It must be noted that certain parts of the potato plant are poisonous. The green parts of the plant, including the leaves, stems, and any green spots on the potatoes themselves, contain a toxic compound called solanine.

Solanine is a glycoalkaloid poison that can cause symptoms such as nausea, vomiting, diarrhea, headaches, and in severe cases, even neurological problems if ingested in large quantities.

It’s important to store potatoes in a cool, dark place to prevent them from turning green and to remove any green areas before cooking.

The tubers (the part of the potato we eat) are generally safe as long as they are not green or sprouting.
