  • Plant tubers about 5cm (1.5") deep covered with soil. Best planted at soil temperatures between 63°F and 95°F. (Show °C/cm)
  • Space plants: 12 - 18 inches apart
  • Harvest in 15-20 weeks. Leave in the ground until foliage has completely died down so tubers reach maximum size.
  • Compatible with (can grow in same bed): Best in separate bed

Yams needs a long growing time to produce the tubers.

Protect from early Autumn (Fall) frosts to give time for tubers to fully develop.

Planting needs are similar to potatoes. Yams can handle more shade than potatoes. Earthing up will help increase production.

The leaves look rather like clover. Dig up after the plant dies down and leave outside for a few days to dry.

Culinary hints - cooking and eating Yam/Oka

Scrub and boil or roast with other vegetables.

Yams are easy to grow - just save some from the fruit and vegetable depatment at the sumermarket. Cheaper that trying to get them from the sead supplier.
