Mountain Laurel Irrigation
The time mountain laurel water needs are the greatest is immediately after the shrub has been transplanted. Mountain laurel should be planted in the autumn when temperatures have just started to drop. You should water the shrub well after you’ve planted it, and then continue to water it regularly and deeply until first frost. Take care not to go overboard and waterlog the soil. Only water enough to give it a good drenching, then let the water drain away. Make sure to plant your mountain laurel in well-draining soil to avoid problems that stem from standing water.
How to Water a Mountain Laurel Shrub
After the first frost, leave it alone. In the spring, when temperatures start to rise again, it’s time to begin watering regularly. It’s helpful to put out a layer of mulch around the shrub to help retain moisture over the roots. Once it is established, a mountain laurel shouldn’t need too much watering. It should be able to get by on natural rainfall, though it will benefit from some supplemental watering during periods of heat and drought. Even established plants should be watered generously in the fall leading up to the first frost. This will help the plant stay healthy through the winter.
