Have a look at https://livingseeds.co.za/potatoes - they sell seed potatoes and ship to anywhere in SA (at the right time of the year). They always stock standard coloured potatoes as well as occasionally some novel heirloom ones. Also on that page is a link with guidance on growing potatoes. Pre-orders are opening soon, shipping is early August ready for you to plant.

You need to work out your climate zone from the BLUE CLIMATE ZONE TAB at the top of the page. Then check when to plant. Buy from seed selling websites, nursery, farmer produce store, hardware & gardening stores.

When growing potatoes what fertilizer does one use
28 Apr 20, Anon (South Africa - Summer rainfall climate)
Just look for a general all round gardening fertiliser. If you look at all the fertilisers for different crops there is not a big difference in the NPK of them. Depending on your soil 8-12N, 3-6P, 3-6K. I read of fertilisers like 10, 10, 10, and 8, 8, 8. I don't know where you buy them (USA stores?).

The guide here says Jan to March - it is now April. I suggest you plant ASAP.

Buy from a nursery, farm produce agency, seed selling online store. Some hardware/garden store might have them.

Read the notes here the info is all there. One thing they say is to plant Aug/Sept etc, same as where I live in Australia. But here they plant April/May and also in Aug Sept.

Are you looking for SWEET potatoes or regular potatoes ..... I think your climate is better suited for Sweet potatoes -- they are different (different families) and therefore have different instructions: The ideal soil temperature range for planting potatoes is 45 to 50 degrees Fahrenheit (7 to 10 degrees Celsius). After planting, the ideal temperature for growing potatoes is 60 to 70 degrees Fahrenheit (16 to 21 degrees Celsius). Potatoes do best in fertile, well-drained soils. However, potatoes will grow in many types of soils. Soils that are poorly drained tend to produce poorly shaped potatoes and tuber rot. Potatoes do well across a wide range of pH, but prefer slightly acidic soils; a soil pH of 5.3 to 6.0 is typical for potato production. If your soil is more acidic than this, mixing in wood ash will help raise the pH and make your soil more alkaline. Sweet potatoes (Ipomoea batatas) are close cousins of morning glory and only distantly related to traditional potatoes. They are tender, so must be protected from frost, and like heat, full sun and regular watering. They crop best at temperatures of 21–26°C (70–80°F) PLEASE CLARIFY which type of potato.
