Myrrh is not a plant itself, but a resin from the Commiphora shrub, which grows in northern Africa and the Middle East. The shrub grows to about 12 feet high, and needs sunny and dry conditions to grow well. Like its native home, the Commiphora shrub grows best in hot desert regions of the world.
Choose a spot in your yard that is in full sun and has well-drained, sandy soil. Add 4 to 5 inches of coarse sand to your soil if it does not drain well enough to grow the Commiphora shrub.
Dig a hole for the Commiphora shrub about 1 foot deep and 2 feet wide. Place the shrub in the hole, and fill the hole with soil. Pat it down loosely.
Water the Commiphora shrub for about 5 to 10 minutes every other week. Commiphora shrubs like dry conditions. Overwatering can kill them.
Cut the Commiphora shrub's bark about 1 inch deep when the shrub is two to three years old. Collect the resin of the shrub, and allow it to dry. This is myrrh.
