Things you should know about smart gardening and landscaping
The following Utilities Kingston web pages contain helpful background information and practical tips for managing your garden in a water-friendly way.
Visit our Conservation Tips page for other ways to save water, energy, & money.
Did you know? Dense and healthy vegetation helps reduce carbon emissions.
By creating small carbon sinks in your backyard, you can absorb and store greenhouse gases, which would otherwise be present within our atmosphere. Plants also create a cooling effect through shade and evapotranspiration (by which plants uptake water from the soil to use for growth and photosynthesis).
Treated water use outdoors
Reducing the amount of treated water used outdoors during the summer is an important part of water-wise gardening. Learn more by visiting Summer Use Water Restrictions.

Water wise plant guide
Term | Description |
---|---|
Sun | Full sun; plants in this category do still benefit from shading of the soil and roots to lower temperature and slow evaporation |
Partial sun | 3/5 to 4/5 of sunlight hours in direct sun |
Bright shade | 2/5 of sunlight hours in direct sun |
Shade-loving | Deep shade to very little sun |
Dry soil | Soil that is usually dry, meaning at higher elevation or high sand content or both |
Well-drained moist soil | Soil that holds moisture but also allows oxygen to penetrate the roots is ideal for most plants. It is achieved through a combination of high organic content and earthworms. |
