Sage is a hardy perennial herb with woody stems and oblong leaves. The leaves are woolly in texture and grey-green color that is lighter on the underside. Sage grows 2 to 3 feet in height, and spreads 2 to 3 feet in width. There are many varieties of sage grown as an ornamental plant, in herb gardens, and for its medicinal qualities.
Determine a place in the garden to plant sage. Choose an area with at least six hours of sun per day. Allow 2 to 2 ½ feet between sage and other plants.
Dig a hole two times as deep and wide as the root ball of the sage plant. Mix one shovel-full of commercial or homemade compost into the hole.
Place the sage plant in the hole with the roots spread out. Holding it upright, fill in the hole with dirt. Press down lightly so roots are secure.
Water thoroughly. Water should drain into the ground easily.
Add one shovel-full of compost as a side-dressing. Spread it in a circle around the plant, 3 inches away from the center stem. It will act as mulch, continuously feeding nutrients into the soil. Mulch also helps retain water.
