How to create a water efficient garden
Step 1 - Soil Preparation
Before planting, prepare the soil to provide nutrients and moisture for plants to thrive
- Determine what type of soil you have and add appropriate organic materials, such as compost, peat moss, or manure.
- Mix the compost or other organic materials into the top 30 centimetres of soil.
Step 2 - Plant Selection
Choose drought resistant plants to lower maintenance and maximize water savings. Consult the City's lists of recommended trees, shrubs, perennials, groundcovers, and annuals
- Group plants by their water and sun/shade requirements.
- Use grass only for well-travelled areas or as a backdrop for flowerbeds.
- Use water efficient irrigation techniques, such as soaker hoses, for vegetables as vegetables require more water.
- Check plant height, season and colour of bloom to build a balanced landscape.
Step 3 - Plant
- Dig an appropriately sized hole for plant.
- Add compost mixed with native soil to the bottom of the hole.
- Centre the plant in the hole and water, covering the roots to ensure adequate moisture at the time of planting.
- Cover the plant with soil matching the soil level of the neighbouring area. Create a berm or ring around the plant to retain water and water the plant.
Step 4 - Mulch
Mulch is a soil cover that helps to control erosion, suppress weeds, retain moisture, moderate soil temperature and reduce disease transmission. Bark, wood chips, compost, grass clippings, crushed or river rock can all be used as mulch material.
- Spread the selected mulch in a layer about 10 cm deep over the garden.
Step 5 - Irrigation
Proper irrigation techniques ensure that your garden receives adequate water and remains water efficient.
- Use soaker hoses or a drip irrigation system to water once a week. This will reduce the amount of water lost to evaporation.
- Position sprinklers to avoid paved and hard surface areas.
- Take into account the amount of rainfall before watering. Leave a measuring container out in the garden to help assess how much rain falls each week.
- Water, if necessary, in the morning. Avoid watering in the afternoon or on windy days when water can be wasted to evaporation.
- Collect rainwater in a barrel for garden use.
- Reduce the amount of asphalt or concrete around the garden to reduce run off and allow the rain to soak into the ground.
