Six Dry Site Solutions
1. Install efficient irrigation - Drip irrigation provides more
efficient water use than overhead sprinklers. Drip irrigation ranges
from inexpensive "soaker" hoses to computerized systems.
2. Reduce fertilizer use during droughts - Fertilizers are salts
that can further stress or kill trees if water is inadequate. Salt
concentrations can build up in the soils due to decreased water
availability. Even controlled release fertilizers may release much more
rapidly during hot weather, causing excessive salt levels.
3. Apply mulches - Application of mulch can improve the water
retention of trees. Mulches also reduce the impact of water droplets
hitting the soil surface, which help reduce soil erosion and crusting
which increases water penetration into the soil.
