Answer: You didn't mention how often you water, or whether or not you used chemical weed killers near the plant so I'm not sure if the dried out leaves are due to water stress or some other problem. It could be that the summer sunshine has been burning the leaves and it only just showed up. Or, it might be that your tree needed water before you left and showed its stress after you returned. In any event I think it will recover, especially if you water on a regular basis. One deep soaking per week should do it. You might try watering via a water well or a basin. Simply scrape some soil out in a circle 12" from the main stem of your laurel and mound the soil up around the perimeter of the basin. Fill this basin with water, allow to drain, then fill it a second time. This method of watering concentrates the moisture over the root mass and allows it to trickle down, wetting the entire root system. Hope this information is helpful!
