vitamin B6, 5 times more vitamin C, and almost 10 times more riboflavin than actual sweet
potatoes. Also an excellent source of antioxidants, high levels of vitamin A, thiamin, folic
acid and niacin with impressive amounts of fiber, calcium, magnesium, manganese, zinc,
copper, potassium and iron. Nutritionally similar to spinach, but sweet potato leaves have less
oxalic acid, which gives some greens like spinach and chard a sharper taste.

Tubers are ready for harvest in 4 months from planting in tropical areas and 6 months in
cooler zones
• To harvest, pull back vines to reveal their base and then use a garden fork to loosen the
surrounding soil and expose the tubers. There can be several tubers ready at each planting
spot
• In warm areas, plants can be left in the ground for several years. Best to dig as needed.
Look for a thickened stem, or walk around feeling for a lump, and start digging.
• In cooler areas, harvest crop before winter .Dig in autumn when the soil is still warm. Cure
in a warm, airy place for two weeks before storing at cool room temperatures. Large tubers
store best. Wash and air-dry for a few days and store in the fridge
Tubers are often found 12 inches or more from the plant's primary crown, so dig carefully.
Haven't grown Yacon before but guess it would be similar... Green Harvest Seed Co QLD
says this ...
HARVEST
The plant takes 6 - 7 months to reach maturity. After flowering top growth withers and dies back and
the tubers are harvested. They resemble dahlia or sweet potato tubers, on average weigh about 300
g but can weigh up to 2 kg. Once the soil starts to heave at the base of the plant, dig around to
'bandicoot' a few early tubers to extend the harvest season. The tubers continue to sweeten as the
plant dies back so the main harvest should only take place once all the top growth is dead, usually by
May. Don't leave it too long though, especially in areas that have mild winters, as the plant will start
to shoot again as the weather warms up and the days get longer. The plant needs to be dug carefully
to avoid damage to the crisp tubers. After separation from the central stem undamaged tubers can
be stored in a cool, dark and dry place with good air circulation for some months. The average sugar
content of the tubers increases during storage because of starch conversion. They can also be
exposed to the sun for up to 2 weeks to accelerate the sweetening process
