Ammis in Barnton

Sow seeds thinly around 28th February - 31st March, just under 0.5–1 cm deep in prepared soil. Keep the surface evenly moist while the seedlings establish, and protect early sowings from birds and slugs.

When seedlings are large enough to handle, thin them to 30 cm apart so each plant has room to branch. Keep the strongest plants and remove the weaker ones cleanly around 29th March - 12th April.

Set young plants into their final position once they are sturdy, spacing them 30 cm apart. Water in thoroughly straight after planting, then use fleece if a cold snap is forecast around 28th April - 12th May.

From 5th May, add light stakes or mesh if the plants start to lean. Ammi can flop in exposed spots after rain, so put support in early rather than waiting for stems to bend.

From 19th May to 6th October, water during dry spells and give a light balanced liquid feed once at the start of flowering if the soil is poor. Avoid overfeeding, as soft growth makes stems weak and floppy.

Cut stems from 4th July as soon as the flower heads open and keep picking through 6th October. Regular cutting encourages more stems, and the flowers last best if you cut early in the day and put them straight into water.
