Requires plenty of warmth and so needs to be cultivated in a greenhouse. Can only be cultivated outside during really warm summers. Sow in February for an early cultivation. Prick out young plants after about 4 weeks, and as soon as the first true leaf appears transplant the plants to large pots of 14 cm. If necessary, later transfer to the ground in an unheated greenhouse. After fructification remove the wilted petals immediately, otherwise the young fruit will perish.
