The design of my food forest uses 3 swales planted with fruit/nut crops along with perennial berries and vegetables. Each plant was selected to fill a niche but also offer some sort for food yeild as well. Once established very few other plants should have room to grow. Instead of weeding, I will be managing the perennials and harvesting. While the perennials establish, I am taking advantage of the light between the rows to grow subsistence crops like potatoes, squash and garlic. When I grow the annuals, I bring fertility into the food forest. When the canopy closes and there isn't enough light to grow the subsistence crops any more, I will have built soil to feed the fruit trees for a long time. There's more to it, but that's the high level concept of my food forest design.
