Strawflowers in Old Grimsby

Sow seeds in modules or trays around 5th January - 29th January at a depth of 0.5 cm. Keep them at 18–21 °C and just moist until they germinate, then give them plenty of light so the seedlings do not stretch.

When the seedlings are large enough to handle, prick them out into individual pots around 7th February - 21st February. Handle them by the leaves, not the stems, and keep them growing on in bright, frost-free conditions.

Acclimatise the young plants gradually around 5th February - 19th February. Put them outside for a few hours at first, then extend the time over about a week so they get used to sun and wind.

Plant out around 5th March - 19th March once frosts have passed and the soil has warmed. Space plants 30 cm apart in full sun, and water in thoroughly straight away.

Check plants from 11th April as they settle in, and keep the soil evenly moist in dry spells. A light liquid feed every 14 days helps maintain growth without making the plants soft and floppy.

From 11th April onwards, deadhead fading flowers regularly by cutting stems back to a leaf joint. This stops the plant setting seed and keeps it flowering well until the autumn frosts.
