What month do you plant primulas?
Seeds should be sown as soon as they are ripe, around late spring to early autumn. Do not cover the seeds with compost as they need light to germinate.
How far apart do you plant primulas?
You can also find them in Garden Centres from late winter for instant impact. Plant them 6 to 12 inches apart and 4 to 6 inches deep. Primroses thrive in damp conditions so water them thoroughly after planting and continue to do so throughout the season.
