Nasturtium 'Banana Split'

Sow March to May. Sow outdoors where they are to flower. Sow seed, 20mm (3/4in) deep in drills 30cm (12in) apart in well-cultivated soil which has been raked to a fine tilth. Water ground regularly, especially in dry periods. Germination usually takes 7-12 days.

Can also be sown in pots or trays of moist seed compost. Cover seed with a sprinkling of compost or vermiculite. Keep at between 15-20ºC (59-68ºF). After sowing, do not exclude light as this helps germination. Keep the surface of the compost moist but not waterlogged; germination will usually take 7-12 days.

For direct sown plants thin out seedlings to 30-45cm (12-18in) apart when large enough to handle.

For pot grown plants, when large enough to handle, transplant seedlings into 7.5cm (3in) pots or trays. Plant out into borders or containers once the young plants are well-rooted in their pots after all risk of frost.
