How Do You Divide Artemisia

It is important to divide many perennials every 3-4 years so they keep producing vigorous new shoots. With Artemisia, take a sharp spade and slice through the clump removing the older center portions. Keep the younger, more vigorous parts of the plant from the outer perimeter of the clump.

Can you split Artemisia?

Artemisia shrubs should be divided in early spring after they have been pruned, cut back or thinned out. Also it is best to dig out your srubs in the morning or late afternoon, when the temperature is not as hot. This is typically true when dividing almost any type of garden flower, plant, or shrub.

How do you cut back Artemisia?

Perennial artemisias can be cut back in the fall or spring. Shrubby varieties should be pruned in the spring. They can handle being cut back hard if you want to keep their size in check. Even non-woody artemisias can get floppy, especially after flowering.
