The Grancy greybeard tree, also known as the Old-man's beard or the Fringe tree, is native throughout the southeastern US, according to the University of Arkansas. These small flowering trees only reach heights of about 20 feet. According to the Bernheim Arboretum and Research Forest, Grancy greybeard trees are hardy to USDA zones 4 to 9. They have large white tufts of flowers that give the tree its name.
Work 5 to 6 inches of compost into the soil to a depth of 3 to 4 feet to improve the soil if it is not rich enough or well drained enough.
Dig a hole as deep as the tree's root ball and twice as wide.
Place the tree in the hole and backfill the hole with soil.
Water the Grancy greybeard tree until the soil is moist and mulch around the base of the tree in a 3- to 4-feet diameter.
