Growing Information

When to Sow

Sow directly outdoors from April to June once the soil has warmed and the risk of frost has passed.

How to Sow

Sow seeds 1–2 cm deep in fertile, well-drained soil. Choose a sunny position and space plants approximately 40–50 cm apart to allow strong root development and healthy growth.

Growing Tips

Water regularly during dry periods, especially while plants are establishing. Improve soil with organic matter before sowing for stronger growth. Due to its height, Henry Wilde may benefit from support in exposed areas. Remove faded flowers to encourage further blooming, or leave seed heads for birds later in the season.
