/\ /\ . Magnolia Grandiflora 'Little Gem' or 'Teddy Bear' dwarf varieties make beautiful evergreen hedges. Height: 20-25' but can be kept 13'. Width: 10-15'. Plant 4' apart. During early years, tip prune new growth by half all around individual trees for good structure and dense form in maturity. Once each plant is thick, prune the face and top of hedge as wide or tall as you like, perhaps 2.5' wide by 13' tall. Round the top.
