Open Your Path to Making the Watering for Your Garden - Simple Tips

Watering the garden plants by means of drip irrigation is unquestionably more effective than by sprinklers and more efficient in terms of water management. Roughly speaking, drip irrigation, if installed and applied correctly, can save at least 20% of the water that is lost in run-off, especially where trees and shrubs are concerned.

Working at the correct pressure

Drip irrigation should operate at as low a pressure as possible. In small, private gardens, a pressure of about 1.5 bars is appropriate. For this purpose, a pressure regulator ought to be installed at the system’s head unit.

Very often, the drippers at the end of the line barely emit water. The reason is usually that the dripper line itself is too long and not because of insufficient pressure to begin with. A common mistake is to snake a line or two around the plants, instead of the correct method, which is to connect several shorter lines to a feeder or supply pipe. For most home garden situations, each dripper line should not be longer than about 15 meters, (45ft) and a lot less with micro-drippers.

The aim is to apply water at a rate at which it can be absorbed by the soil, while supplying an even cover of moisture for the plants’ roots. For this reason, it is important to know the flow rate of the individual drippers. It is best to choose those with the lowest flow rate available (flow rate is the volume of water emitted per unit of time) especially in heavy, clay soils and on slopes. For flowers, where complete coverage is usually necessary, it is wise to use micro-drippers, where the flow rate of each unit is 1 liter per hour.

Care and maintenance

Blockages are the main problem associated with drippers. Firstly, a filter designed for drip irrigation should always be installed. Secondly, it is wise to flush the lines once or twice a year. This from my experience can extend the lifespan of the system to some 10-15 years, whereas failure to carry out this simple procedure is liable to result in blockages after 2-3 years. Ultimately, the drippers will block up from the mineral deposits that accumulate over time.
