There are six different types of irrigation and sprinkler systems that Life Landscapes, the landscaping division of Life Green Group, works with. All of which offer different watering services to a garden.
Irrigation has revolutionised watering. A hosepipe is an outdated way of watering a garden. Hosepipes damage vegetation, require manual labour and wastes water – delivering large quantities of water to a small area. The type of irrigation system you require depends on the watering objectives of clients, the type of garden and the plant species.
We often hear our irrigation manager saying: “Irrigation delivers the minimal amount of water at the optimal time.”
We caught up with Moses and Lordwick from the Life Landscapes irrigation department to find out about the different types of irrigation and sprinkler systems.
This is the most water-conscious of irrigation systems. The water is distributed directly onto the root system of the plant. Drip irrigation needs to be run for 30 minutes for it to take effect. Pipes with perforated holes are buried just below the surface, a blocker only lets the droplets out one at a time. Drip irrigation is a subtle way of watering without citizens getting angry about water restrictions.
Greenwalls also use a type of drip irrigation for watering. Gradient plays an important role in the way the greenwall irrigation controller is set. If set incorrectly it could cause flooding at the lower half of the greenwall and dry conditions at the top.

Are more commonly used in flowerbeds. The nozzles are interchangeable to control volume, angle and direction of water flow. A riser pipe needs to be on for 10 to 15 minutes to be affective for flowers. A riser pipe needs to be set at the correct time to ensure less evaporation and maximum absorption by the garden. If set in midday the dew drops on the plants can act as a magnifying glass and burn the leaves.
Riser Pipe Irrigation
Pop up sprinklers occur bellow the lawn. The pressure of the water pushes them out the lawn. The shafts can be made longer to ensure a longer length of spray. Pop up sprinklers are mainly used for lawn and sporting facilities. Grass sports fields often have to be watered midday to cool it down as certain grass species come for cooler climates.

Are very effect for delicate plants and high foot traffic areas. The water is forced through a small hole forcing the water droplets to mist up. This then settles directly on the plants and is absorbed. A mist pipe is ideal for greenhouses, slight or delicate seedlings and special collector’s plants. They also stop people getting wet in nurseries or public spaces but still allow for the watering timetable to be fore filled.

This type of sprinkler is used for professional sports fields and it pumps volume. Life Sports Turf uses cannon sprinklers on professional soccer fields, rugby stadiums and cricket pitches as the grass needs large volumes of water to keep it in tiptop condition. International stadiums tend to have bigger budgets too.
