Frost-sensitive Mediterranean species will be better grown in a pot (or outside if you are in a mild region) in a draining mix (add clay balls or gravel to your potting soil if it seems too heavy).
Do not hesitate to plant all other sagebrush in open soil. Avoid absolutely poorly drained, heavy soil.
Work the soil with the spade then with the claw, to a depth of two spades for the shrubs, and to one for the perennials.
Add a fertilizer during the plantation (compost, manure well decomposed on the top of the soil, etc.)
Plant without burying the limit between roots and branches.
Tamp the soil to put the soil in contact with the roots.
Water until the water is no longer absorbed by the soil.
Water my mugwort
Water once a week the first month. In open soil, watering is not necessary except in case of intense drought.
Fertilize my mugwort
A small input of natural fertilizer like compost will not hurt in early winter, to keep a rich soil around your mugwort.
Cut down my mugwort
In autumn, trim the foliage of the perennial sagebrush at the base.
Prune my mugwort
In March, before the vegetation regrows, prune the sagebrush with shears to restore its compact, globally spherical shape.
Shelter my mugwort
Bring non-hardy potted plants inside before winter.
Put outside my mugwort
After the last frosts, you can take out the potted sagebrush.
