WATER CONSERVATION AND YOUR LAWN

When we conserve water, we are ensuring its availability for future generations.

When we have water, we extend the life of facilities that treat and distribute water and reduce the amount of wastewater discharged to streams and rivers.

Water conservation also makes it easier to maintain drinking water supplies during droughts.

Here's a remarkable fact: More than half of the water we apply to our lawns and gardens is lost to evaporation or runoff. This means that we are overdoing it and wasting water. Overwatering is bad for the lawn - it weakens roots and makes lawns more susceptible to drying and burning.

Smart ways to water your lawn

Lawn-watering should be done slowly, deeply and infrequently. That way, your lawn gets just what it needs and you don't unnecessarily waste water.

How much is enough? About two to three centimetres each week, whether it comes from rainfall or watering.

One exception to this rule is for new grass seed or sod. Then it's okay to make sure your lawn gets two to three centimetres - two or three times a week - for three weeks, or until grass is established.

Use a rain gauge or place containers on your lawn to determine how much water has been applied.

The best time to water the lawn is early in the morning. This way you reduce the amount of water lost to evaporation.

The types of hoses and nozzles you use are important.

Irrigation or soaker hoses are perfect for the garden - they apply water slowly and directly to the soil. Use pistol-grip nozzles on hoses; always turn off the faucet tightly to prevent leaks. Don't use sprinklers that produce a fine mist because too much water gets lost to wind and evaporation.

Alarm clocks and stove timers can help remind us to shut off sprinklers.

Finally, don't water your lawn when water is in short supply.
