dividing Dierama pulcherrimum

Question

Best season to divide? Does the foliage need to be cut back before digging? How many corms should one replant in order to have a strong stand ?

Answer 1

It is less about the season that you can divide, and more about letting them multiply until their flowers start to slow. This will happen after about 5 years. Here is an article that will explain better: https://www.gardeningknowhow.com/ornamental/bulbs/wandflower/growing-dierama-wandflowers.htm
