Seed - surface sow in spring or autumn onto a pot of permanently moist soil in a warm greenhouse. Emmerse in 5cm of water and do not water from overhead. Grow on until the seedlings are 0.5cm tall then remove from the water and pot up a week later. Seedlings are liable to damp off when grown this way, sowing the seed thinly, good ventilation and hygiene are essential for success[
]. Grow the plants on for at least their first winter in a greenhouse and then plant them out in late spring or early summer, after the last expected frosts. Consider giving the plants some protection from the cold for their first few winters outdoors.
