I prepared a bed 5 feet wide, 75 feet long that runs up against the north side of my neighbors 6 foot tall fence. I purchased 24 shrubs that are being delivered next spring: salmonberry/thimbleberry/highbush cranberry/aronia/serviceberry/nanking cherry. I am planning on planting them 3 feet apart to form a hedge. My question is how far from the fence do I need to plant these? Do I need to make my bed wider? The entire area gets sun in the morning, than by 1pm the fences shadow covers the entire bed...
