Cultivation and Growth
Growing Conditions
Yacon prefers well-drained soil and a cool climate.
It can tolerate a range of soil types but thrives in fertile, loamy soil.
It is sensitive to frost, so it’s typically grown in areas with mild winters or as an annual in colder climates.
Planting and Propagation
How to grow yacon
Yacon is propagated from rhizomes, which are underground stems that produce new shoots.
Rhizomes are typically planted in spring, after the risk of frost has passed.
The plant requires adequate spacing to allow for tuber development.
Harvesting
Yacon tubers are typically harvested in late autumn or early winter, after the aerial parts of the plant have died back.
The tubers are carefully dug up and cured in the sun for a few days to enhance their sweetness.
It is important to harvest the rhizomes seperately from the tubers. The rhizomes are what will be used for the next years crop.
Nutritional Value
Fructooligosaccharides (FOS)
Yacon is rich in FOS, a type of prebiotic fiber that promotes the growth of beneficial bacteria in the gut.
FOS are not digested by the human body, so they contribute minimal calories.
They have been shown to improve digestive health and boost the immune system.
Other Nutrients
Yacon also contains antioxidants, vitamins, and minerals.
It is a good source of potassium, which is essential for maintaining healthy blood pressure.
It also contains small amounts of calcium, iron, and other essential nutrients.
Low Glycemic Index
Yacon has a low glycemic index, meaning it does not cause rapid spikes in blood sugar levels.
This makes it a suitable food for people with diabetes or those looking to manage their blood sugar.
Health Benefits

It can help alleviate constipation and improve bowel regularity.
Blood Sugar Control

The fiber promotes feelings of fullness, which can help reduce calorie intake.
Antioxidant Properties
Yacon contains various antioxidant compounds, which can help protect the body against free radical damage.
