Shrub Hedges
Any shrub or small tree can be used to make a hedge, but of course some are better than others. Spireas make excellent fast growing, low to medium height hedges, as does forsythia and Potentilla. Lilacs, Weigelas, and Burning Bush can also be used. Make your selection based on how tall you want the hedge to be, how fast you want it to grow and of course what kind of look you want. Generally space hedge plants one half to two thirds the mature plant width apart, depending on how fast you want the hedge to fill in.
When planting Spiraea bumalda ‘Frobelli’ as a hedge, space 3’-4’ apart. Cut back by at least 1/3 in spring or fall.
