3 months ago I planted 12 x 3 ft high laurel bushes 2ft apart. 11 have taken and are growing at a rapid rate; however, 1 bush is growing very slowly and furthermore, the leaves are turning yellow and some are starting to drop off. The leaves are clear of any disease or pests. Is this bush a dud or should I just leave it and see if it recovers. Would some pruning help?
