I have a vegetable garden in the backyard and also fruits/vegetable plants are grown in containers at the terrace. It was really a headache to water them regularly, especially plants in containers which needs regular watering. Then I came to know of something called drip irrigation and purchased its materials from a nearby agricultural shop. It was quite easy to assemble and use it. The best part is that it saves a lot of water and as water reaches exactly in the root area of the plant it is very effective too. Whenever I am away from home my parents can easily water the terrace plants just by opening the tap at ground level in which the drip irrigation hose is connected. We can also give liquid fertilizers through this system.
