Choose the proper time to plant your sage, such as late spring or early summer.
Fill a container or hole in your garden area with a commercial garden soil mixture.
Use a garden trowel or claw to dig bone meal into the soil in the container or garden hole.
Use a garden trowel to dig a small hole in your prepared container or garden area. Make the hole large enough to contain the roots of your sage starter plant.
Remove the sage starter plant from its nursery container (do so carefully so you don't damage the young plant's roots) and place the plant's roots, soil and all, into the small hole you dug.
Fill the area around the sage plant with some of the displaced soil you have already treated with bone meal.
Place a strong stake into the container or ground just behind your new sage plant to support it as it grows larger.
Water the sage daily at the roots to maintain moisture levels in the soil. Do not overwater your sage as it could kill the plant.
Dig more bone meal into the soil around the sage plant at the end of the summer to prepare the plant for harsh winter conditions and to help it recover from a productive summer.
