Once planted, laurel hedges require little maintenance except for pruning to keep to desired height and size. The plants spread naturally and prolifically by a propagation method called suckering. Suckers are underground runners the mother plant produces. New plants arise from the nodes or the points where the leaves grow.
Using suckers laurel hedges is an easy way of propagating new plants for other landscape areas. Since the suckered plant sections have already produced roots, establishing new plants is easier and more successful than with seeds or cuttings. The best time to divide and plant suckers is during spring, as this gives the new plant enough establishment time before cold fall and winter weather.
Dig up the small plant with a sharp spade. Keeping the sucker's roots covered with original soil minimizes drying. Sever the baby plant from the mother with hand pruners or sharp scissors, as a spade damages the roots. Plant the sucker in a moist, fertile soil where the new plant will not face competition from grass or weeds. Water it regularly and apply a liquid fertilizer weekly for faster establishment. Stop using fertilizer by midsummer.
Laurel hedges grow best in areas of full or partial sun, depending on variety, and generally do not thrive in poorly draining, soggy ground. Amending the soil with organic material improves soil fertility. Most laurels are fast growing and require regular pruning if a desired shape or size is required. Let the plants grow in their natural form if an informal hedge is desired.
