Growing calendar
Sowing & growing
Mar-May sow outdoors, 2 seeds together, 1.5cm deep, every 45cm in pre-watered, finely prepared soil. When seedlings appear, remove the weakest. Keep well-watered until established and protect seedlings from late frosts. Alternatively, sow indoors Mar-May and grow on in a greenhouse or coldframe. Plant out when risk of frost has passed.
Aftercare
Seedlings sown outdoors may need protection from slugs and birds. Once flowers have faded, the dead heads can be left on the stems to feed local birds.
