Xeriscape Watering Needs


Watering Needs 

The rate at which plants use water is called evapotranspiration or ET. Temperature, humidity, wind and light all influence the ET rate. When watering, you only need to replace the amount of water that has been lost due to ET.   Once the plants listed in this brochure are established (usually one year or 2-4 weeks for annuals the water requirements are as follows:

X- Xeriscape = .5 ET (about 1" of water per week)
XX- Xeriscape = .25 ET (about 1/2" of water per week)
XXX- Xeriscape = .125 (about 1/2" of water every 2 weeks)
