Reduce lawn space and save water

Native verge gardens

Native verge gardens are a great water efficient alternative to lawn.

If you plant these gardens in winter, you don’t need to install permanent irrigation as hand watering should be sufficient during hot periods.

The verge is the perfect, unused space to attract biodiversity and show off native plants in flower at all times of the year.

Effective hydrozoning principles

Hydrozoning and reducing lawn space

Hydrozoning groups plants with similar needs together.

It involves classifying garden areas based on the garden’s fertiliser, water and maintenance needs.

Identify which areas require more resources based on visual importance or amount of use.

Some simple hydrozoning principles to consider:

Minimise plants with high water and fertiliser needs

Generally lawns require more water, fertiliser and maintenance than a shrub bed; similarly with exotic shrubs compared to native shrubs and succulents.

Group similar plants in each hydrozone

Plants should be grouped according to their fertiliser, water and sunlight requirements. For example: lawn and shrubs should be on separate hydrozones

Irrigate based on hydrozones

Use the identified hydrozones to assist with your irrigation layout. For example, it is recommended that sprinklers are used across all lawn areas and drip irrigation for garden beds

Use consistent sprinkler heads on each hydrozone

This ensures even water distribution and pressure to maximise water efficiency

Reduce the amount of hard surfaces

Water saving technologies

Irrigation efficiency

Install a rainwater tank to collect rainwater from your roof, which can be used to irrigate your garden or plumbed directly into your house.

Greywater systems recycle water from your laundry, shower and basins to irrigate your garden through sub surface drip irrigation.

Greywater pipes are always purple. If you have a greywater system, you will need to be careful what cleaning products you use.

Weather-based technology

Automated, water saving technologies will help you save water and reduce runoff.

Install simple irrigation technologies such as a rain sensor or soil moisture sensor.

These can adjust your irrigation watering run times during/ following rain events.

There’s nothing worse than seeing sprinklers running during a downpour! Your lawn and plants can’t use excess water (or nutrients for that matter) so it is lost to our stormwater systems.

Consider the use of:

  • Automatic irrigation systems
  • Evapotranspiration sensors
  • Weather stations
  • Rain sensors
  • Soil moisture sensors
  • Drip irrigation for garden beds
  • Gear drive, rotary and fixed spray sprinklers for lawn
