| Sowing, Seeds, Planting | Plant out your seedlings from late August to October. Seedlings can go straight in the border, or you can grow on in 9cm pots until they reach 10 to 15cm in height, at which point, they’re ready to plant out. The ground should be prepared before planting out. Dig it over thoroughly and mix in plenty of organic matter – such as manure or leaf mould. The planting location should have good drainage and ideally the soil should be slightly alkaline. |
| Care Tips | Regular picking of flowers and deadheading your wallflowers is important to prevent them running to seed. |
| Flowering | March - May |
| Vase Life | These will last up to ten days in clean water. Strip the bottom leaves and sear their stem ends in boiling water for 20 seconds. |
