Mountain laurel thrives in well-draining, acidic soil with a pH ranging from 5.0 to 5.5. Use a soil pH testing kit -- available at garden centers or home improvement stores -- to test your soil. If the soil in the planting area is higher than 5.5, mix 1 to 2 inches of sphagnum peat moss into the soil's top 6 inches.
