We live on Keats Island in Howe Sound, near Vancouver, BC - Zone 8 or 9 - and are starting to put in a vegetable garden and small orchard. We also need to deal with a water supply and storage tanks.

Could anyone suggest what a typical volume of water would be per day (perhaps, per sq.ft.) so I can get a sense of what size tanks we'd need to carry us through a dry spell in the summer?

Thanks for any assistance.

Eric, about a year ago, an article ran in the Edmonton Horticultural Society's newsletter about this very subject. Here is what they said.

"As a rule, I'm told that most annuals and perennials need about an inch of water a week. That is, an inch deep around the plant should be wet. To get your soil wet enough, you will need approximately a half a gallon of water for every square foot of ground. Of course, the actual amount of water required will vary depending on how hot the weather is and the type of plants you have in your garden. You will need to experiment with water amounts to find the amount that is just right for your plants.

If you have a rain gauge near the plants, you can use this to measure the amount of water your plants have received. A quick and easy alternative to the rain gauge is a simple container left out among the plants. Turn on the sprinkler and leave on until an inch has accumulated in the bottom of the container. Leave the container out all the time and then, if it does rain, you can accurately determine how much rain fell and whether or not you really need to water after all."

Hope this helps.
