Planting young plants

From Early Spring TO Early Spring

Solanums prefer a neutral to slightly alkaline (limey), well-drained soil in full sun. Plant pot grown young plants in early spring or grow on in larger contaners. This variety can be trained as a standard.

Propagation by cuttings

From Early Summer TO Early Autumn

Take semi-ripe cuttings from summer to early autumn, about 3in long with a heel of older wood. Place around the edge of small pots of multi-purpose compost, place a polythene bag over them and put on a bright windowsill, away from direct sunlight. Gentle heat beneath will speed the formation of roots. The cuttings should root in about four weeks. Pot up individually, protect from frost over winter and plant out in spring.
