Water laurels with several gallons of water regularly during the first season and only during severe drought in following years. Water at ground level to prevent soil-borne pathogens from splashing onto plant leaves.
Replenish mulch each spring to conserve moisture and protect roots from sun and wind. Maintain a 1- to 2-inch layer of organic mulch, such as shredded bark or leaf mold.
Fertilize sparingly with all-purpose plant fertilizer, such as 10-10-10, in late winter. Scratch one-half cup to one cup granular fertilizer into the soil around each plant. Organic and slow-release fertilizers minimize plant damage from excessive fertilization.
Prune laurel with handheld pruners in spring, after the flowers fade, by removing stray branches and those that don't contribute to a pleasing, rounded shape. Cut away diseased and dead branches whenever you find them. Sterilize pruner blades with rubbing alcohol or disinfectant spray before and after each pruning project.
