What Causes Salt Damage?
Salt damage can occur from the accumulation of the mineral through ocean spray, road salt runoff, watering with salt-softened water, and even animal urine. Salt then builds up on all aerial parts of the herb, as well as the roots. This accumulation, also known as salt burn, weakens and then kills the herb.
How Do I Protect My Herb Garden From Salt Damage?
Protect your herb garden from salt damage by putting up barriers to protect from ocean spray, fences to deter animals from marking and flushing or rinsing the herbs regularly with fresh water that has not been treated with salt.
