How much water is required to irrigate plants in pots and other containers? This question is becoming increasingly important because of growing concern for water availability and the resulting need for its conservation. Too much water is wasteful and too little results in poor crop growth. This article briefly discusses one aspect of this question: How much water should be applied at each irrigation? It is well known that different floricultural species require different amounts of water. Some need frequent irrigation and use tremendous amounts of water, while others survive for days, weeks, or even months without watering. Some require lots of water but can't tolerate a wet soil. Others can survive without much water but grow faster when supplied with lots of it; however, these plants may also be more susceptible to disease in wetter soils.
