Q When should I divide primulas?
A September is the best month. It might seem an odd time to be thinking about spring-flowering primulas but it’s the perfect time to divide existing clumps to make new plants. This is because primulas are coming into growth then and any root damage that occurs during division will soon recover. When they flower in spring, primulas are about to become dormant so divisions taken then are more likely to rot.

Q How do I divide primulas?
A In September, dig up the plant. You'll find that it's made up of several rosettes of leaves. These can be teased apart to create new plants. Replant straight away to avoid the roots drying out. Water well after replanting and every week for the first few months while the plant is growing roots into the surrounding soil.
