Figure 4. Indian Hawthorn (Rhaphiolepis indica) is tolerant to salt spray and soil salinity. This species does not require extra management input when irrigated with recycled water. Even after several years in a landscape sprinkler-irrigated with recycled water containing 200 mg L-1 sodium and 300 mg L-1 chloride, Indian Hawthorn plants show no signs of salt stress (upper left). If the salt concentration in the irrigation water increases to 600 mg L-1 sodium and 900 mg L-1 chloride Indian Hawthorn leaves can show scorch-like symptoms at the tips of the leaves (below left).
