Abelia is a semi-evergreen shrub that grows from 6 to 10 feet tall with a spread of 6 feet. According to the University of Florida, abelia is hardy to U.S. Department of Agriculture planting zones 5 to 9 and it flowers from spring until fall. Abelia can grow in nearly any type of soil, from sand to clay to loam, alkaline or acidic. This shrub is grown widely in the Southern states, according to the University of Arkansas.
Remove any dead, damaged or diseased foliage as it occurs on the abelia. Cut it off with the pruning shears at the base of the branch.
Remove any old wood from the abelia in the early spring before it flowers. Old wood is usually 1 inch thick or more. Cut off at least a third of the old wood. Trim back to the base of the branches with the pruning shears.
Trim off the tips and shoots of abelia during the growing season, from spring to summer, as they out grow their bounds, according to the University of North Carolina. Trim them back gently to the desired shape with the pruning shears.
