What do you do with wallflowers when they have finished flowering?
Dig them up and compost them after flowering. Plant perennial wallflowers between May and September. Cut back periodically to maintain a good shape and promote flowering. Take cuttings regularly to ward against losses.

How long do wallflower seeds take to grow?
Wallflower seeds should germinate within 7 to 14 days. As the seedlings grow, thin in stages to achieve final spacing of 15cm so the plants can grow nice and bushy. In the early autumn pinch out the main growing point and transplant the plant to their flowering positions, 30cm apart.

How do you propagate wallflowers from cuttings?

Do poinsettias grow from seeds or cuttings?
