Tropaeolum minus, 'Black Velvet'

Germination

Direct sow Mar-May where they are to flower. Sow thinly 20mm deep into drills of finely prepared soil which has been raked to a fine tilth. Allow 30cm between rows. Cover the seed with soil and water. Seedlings appear in 10-12 days. Thin to 30cm spacing when large enough to handle.

Growing

Prefers poor soil, if soil is too rich foliage is produced at the expense of flowers. Water regularly until established. Once established requires little attention.

Cultivation

Cut back after flowering.
