With an estimated 600 acres of window sill growing space across the country, the UK's National Trust just launched a campaign encouraging apartment dwellers to plant window box vegetable gardens. While we are quite familiar with window sill herb gardening, we must admit we had never really thought of using the space for more substantial foods.
The National Trust recommends growing lettuce, radishes, beets, chard, and zucchini, among other vegetables. We're not sure one could be self-sufficient with a window box garden, but it's an option worth exploring for those without balconies, yards, or allotments.
Here are some sites we've found with further advice. And we would love to hear from any readers who have tried growing vegetables in window boxes. Which foods were successful, or not? Do you have any tips for containers, plant spacing, etc.?
