Thank you guys, when I first bought the house they came out and marked so I remember that gas comes in there but not exactly. Don't I need to make a level trench so really cutting into the slope? My veggie garden is also a raised bed on a moderate slope and that's what I ended up doing, this is a lot deeper though.
Dizzy, this area is very shaded with about 4-6 hours of afternoon sun That's why I first thought of hydrangeas, but I love incorporating edibles into my landscape, any thoughts?
