Seed is best sown in autumn then transfer the tiny seedlings to pots and grow through winter in a frost free area, In areas that get frosts even green houses can freeze inside. Springtime plant out and allow each of these new varieties to grow till their tops die down late in the season, then its a matter of digging up each plant and assessing which plant has produced the best yield and for desirable shape and colours. The first year tubers are not always the largest but instead its normally when they are replanted in the second season that they will produce far greater yield. It's worth remembering that new TPS cultivars are virus free.
