Named cultivars do not come true from seed, so buy ready-grown plants for planting in spring. Roman chamomile can be started from seed. Sow seeds in late spring onto the surface of pots and cover with a thin layer of vermiculite. Place in a heated propagator to germinate. When seedlings are large enough to handle, prick out into individual pots.
Plant well-rooted seedlings or bought plants into light, well-drained soil in a sunny position. Alternatively grow in pots of soil-based compost or multipurpose potting media including peat free.
If you are planning on creating a chamomile lawn or seat, space plants 10cm (4in) apart, making sure the site is well prepared and weed free. Keep weed free until established by hand weeding.
Water plants regularly, especially those in pots, in periods of drought over summer. Chamomile can become leggy unless it is clipped regularly during the growing season to ensure growth remains compact, dense and bushy.
If growing plants in pots, raise up on pot feet to prevent excessive moisture rotting plants over winter.
Occasional rolling and treading of lawns will help to maintain an even surface.
