But why is edible landscaping surging in popularity again? For the same reason it did before: high oil prices. The energy crisis of the 70s led to high prices for food and uncertainty about the future, making vegetable gardening seem practical and maybe even critical for future well-being. Of course, with the current high price of oil, food prices are again skyrocketing; the uncertain financial position of the United States has put many people in doubt about their future. At times like this, a tree covered in free apples begins to look as beautiful as any shade tree!
When economic outlooks are gloomy, frugal concepts like edible landscaping get a lot of attention. But when the bear market turns bullish (as it eventually always does), fresh food from the garden is still tastier and healthier than anything found at the supermarket. So why plant an "ornamental" tree when you could plant something both beautiful and productive?
