Primroses form a beautiful rosette with flowers in the middle, but over time, with regular pruning, they become cluttered with pruned-out stumps and need dividing.
Somehow my divided primroses never get that pretty rosette aesthetic that you find when they're shop-bought. Flowers tend to grow from one side or the other rather than in the middle.
How can I give my primroses the best aesthetic when dividing?
