Because the garden is in the middle of a forest and is surrounded by tall trees, most of the sunlight doesn't occur overhead, but at an angle when the sun is lower. My problem with using trellises is that they block the sun. The only place I can use a trellis is at the back of my beds, and because most of the vegetables I'm planting (like tomatoes, beans, peas, cucumbers) need support and if supported will grow upwards: I can't used a trellis or sticks on the front bed of my garden or else they will block the sun from reaching other plants. Any ideas?
