Gardening Gerald Filipski Water Cons We are living in the time of climate chang problems for gardeners. We all need to be conserving this precious resource as keepers of the earth. Conserving water can be as simple as collecting rainwater in a barrel to use to water your plants. The barrel can be metal or plastic, although plastic is easier to maintain and can be purchased from many garden centres or plastic supply companies. Cover the top of the barrel with a screen or mesh to keep out debris and mosquitoes, and you are ready to collect. Make sure the screen is fine enough to keep the ‘skeeters’ out. Adding a tap or spigot can make dispensing the water easier. Rainwater does not contain chlorine or other chemicals found in city water. There are some amazing facts when considering how much rain can be saved from the downspouts of an average house. You can easily calculate the area of roof that drains into a downspout by multiplying the width times the length of the roof. If your roof measures, for example, 12 metres by 7.5 metres, the area would be 90 square metres. For every 2.5 centimetres of rain that falls on a 90 squaremetre catchment area, you could capture up to 2,250 litres of water, but the actual amount will be less considering losses to friction, evaporation, and spillage. This can go a long way in helping to preserve one of our most important natural resources. Also, your plants will love the rainwater better than tap water. 20 | arta.net
