As previously noted in “What Impact Does Recycled Water Have On Plants In The Garden” this is the first in a series of data as provided from the UC Davis Report on “Landscape Plant Selection Guide For Recycled Water Irrigation“.

For this massive table, plants are listed in 4 columns. The first is its Botanical Name, second column is Common Name, third column is its tolerance to salt spray and fourth column is its tolerance to soil salinity.

Plants were watered with spray irrigation from recycled water.

As mentioned from the previous post,

  • High Tolerance can withstand “salt spray with 1000mg/L-1 NaCl and are tolerant to soil salinity beyond 10 dS/m-1. “
  • Tolerant  plants leaves will begin to show stress with salt concentrations beyond 200-300 mg/L-1 and are tolerant to soil salinity below 6 dS/m-1.
  • Moderately Tolerant plants can handle spray from most recycled water but “may show signs of stress later in the growing season as salt accumulation on their leaves is high.”
  • Sensitive plants “may develop stress symptoms under salt spray if the water sodium concentration reaches 200 mg/L-1 … especially during warm and dry conditions. Plants sensitive to salt spray are also sensitive to soil salinity. For example, roses may develop severe salt stress if soil salinity reaches 3 dS/m-1.

High Tolerance plants are labeled with H.
Tolerant plants are labeled with T.
Moderately Tolerant plants are labeled M.
Sensitive plants are labeled S.
