What to Look For
Sweet potato should be firm and smooth with no injuries to the skin or sprouting.
- 12.5°C - 15.5°C
- >95% Relative Humidity for long-term storage
Store sweet potatoes in a dry and cool place. Under these conditions, sweet potatoes can be expected to keep for as long as 6-10 months, however, sprouting may occur earlier.
Sweet potato is highly sensitive to chilling injury at any temperatures below 12.5°C. Damage done to sweet potatoes may not appear until weeks or even months after the chilling injury.
Symptoms include pitting, dry matter loss and pithiness, discolouration, and increased susceptibility to decay.
