I am ready to harvest my Jerusalem do I leave them in the ground to harvest them again in September or do I pick them now to be planted then?

It is recommended to leave the tubers in the soil, they will grow by themselves when the climate allows them to.

In answer to those seeking advice about where to buy Jerusalem artichokes in Cape Town: I bought some Jerusalem artichokes at the Vineyard Deli, Kenridge, chopped them into small pieces and planted them in a large wooden container. The plants are now (October) about 50 cm high and not flowering yet, but looking extremely green and sturdy.

Not sure if you have come right yet, but if not... Jerusalem artichokes will probably not be on sale until the end of the season - at the moment they are putting all the energy into the flower and won't be of a quality to sell. You can keep an eye on www.seedsforafrica.co.za and www.theseedvault.co.za, both of these sites usually have tubers available when in season.

There could be a number of reasons including; a dry spell, cooler weather, planted late in the season, etc. but if your plants are healthy I don't think you need worry.
