I agree with Kahn. You will be amazed how much food you can grow on 1 acre. You are not growing massive foods such as a farm would to have a cash crop. To be honest with you, I would not attempt to grow a 1 acre garden by myself. I would imagine it being a sunup to sundown project. I would start a compost bin/pile NOW to get a head start before next spring. I don't know about Vancover but can you plant winter cover crops there? Something that can be turned over in the spring to help nourish the soil and get it ready for a bountiful summer growing season. Of course, if your ground is frozen all winter, I would assume that would not be possible. If I wanted tons of veggies I would stay clear of crops that require a lot of space - like corn which produces a huge plant but only 3 or 4 ears of corn. There are lots of ways to save space, ie. cucumbers and melons that you train to grow on trellis and fashion a "sling" over the growing food and tie it to the trellis, use the "teepee" method to grow pole beans and vining peas and I'd go with raised beds where you can plant more plants in a condensed area. However, I am not fond of raised beds as in my experience they are expensive and require more water. But, I keep hearing that they produce more crop, so maybe I should give it a good try. Have you ever heard of Square Foot Gardening? I think that's the name of the book. Supposedly this book explains how to grow more crops with less land. Good luck to you. Starting your first garden is hard work but it will get easier.
