Commercial avocado is successful if trees are regularly irrigated and the frequency should be adjusted depending on soil and weather conditions. The avocado trees show water stress suddenly by shedding fruits and leaves or by wilting as they have shallow root system. Loose and sandy soils require larger quantities of water than heavy soils. Generally in summer, trees should receive irrigation once in 10 days and adequate soil moisture after fruit set is necessary to sustain fruit growth, because any setback in growth is irreversible.
