Root depths of strawberries and beans?
Does anyone know what the root depths of strawberry plants and green beans are? I would like to plant them together (recommended companion planting) in a raised bed of less than six inches, but I don't know if that will be deep enough for them. The beans I will string along posts and wire around and amongst the strawberries. And with such a shallow raised bed, what are the rules for layering, as one would do for a deeper no-dig patch? Thinner layers of straw/compost/manure etc, or less layers?
