Reduce your costs. Stop dragging those garden hoses around for hours every few days.

Here are some steps we recommend to conserve water and still have a great garden!
Did you know that sprinklers typically use 950 litres of water per hour?
- Your lawn is not as thirsty as you may think. It only requires 2.5 cm (1 inch) of water in one week period – use a rain gauge, marked tuna can, or frisbee to measure how much water your lawn is receiving.
- The sun is at its most intense between 10:00 AM – 4:00 PM. 40% to 60% of water applied to lawns and gardens during that time will evaporate! Water your lawns and gardens in the early morning or evening. It is cooler and there is less wind.
- Leave grass clippings on your lawn. They will discourage weeds, help to retain moisture, and replenish the soil with nutrients.
Water selectively – vegetable gardens and container plantings require a steady supply of moisture. Give those your attention every two days. Wise watering tips for vegetable gardens include:
- Watering in early mornings or late afternoon; never at night.
- Watering at the base of plants whenever possible to avoid wet leaves that are more susceptible to fungal diseases.
- Using drip irrigation or other methods that avoid splashing the soil onto the leaves and stems which results in transmission of spores and disease.
Plant selection – Did you know that plants with gray, fuzzy, waxy or finely divided leaves are considered drought-tolerant? Plants like daylilies, clematis, flax, lavender, sage, bellflowers and peonies thrive under dry conditions. More about Plants for Soil Types. and Drought-resistant Gardening
Soil amendments – organic matter in soils vastly increases the water-retention capabilities. Incorporating 5-7 cms (2-3 inches) of compost or well-composted manure into your beds will reward you with healthy growth and reduce the need to water. Healthy plants are also more immune to disease!
Mulch – covering the soil is perhaps the most effective way to reduce water needs. Evaporation is reduced and temperatures in the soil are modified. Add 5-7 cms (2-3 inches) of cedar mulch to all shrub and ornamental beds. It looks great, reduces evaporation and keeps the weeds down too! More Mulching tips.
Collect or Divert FREE water – rather than allowing massive runoff into storm drains, why not harvest rain whenever possible by directing your downspouts ? Ideas include Rain Gardens and Rain Barrels.
Lots of great ways to conserve and still have a beautiful and bountiful garden. Let’s all do our part!
