Hand watering is often an ineffective method of watering plants because water is applied at a rate that exceeds the ability of the soil to absorb the water or not enough water is applied. To reduce runoff, use a water breaker nozzle that divides the spray into rain size droplets. Do not use a trigger-type nozzle. Larger shrubs will need more water. If runoff occurs before you have applied the correct amount, move to another spot and come back after the water has soaked in.
Many gardeners use an inexpensive hose-end sprinkler.
Hose-end sprinklers come in many sizes and shapes. Rotary sprinklers generally apply from 1 to 2 inches of water per hour. Since sprinklers apply water into the air, a considerable amount can be lost to evaporation. This is especially true on windy days. The sprinkler should be turned off if runoff occurs.
