When we bought it, I was saying "the first thing I'm going to do is rip out all those green balls across the front." But then we had to restore the (huge) deck and then I was building all kinds of raised beds for vegetables (8 so far) in the back yard and ... the green balls are still there. Two years later they are almost all grown together and half again as tall, blocking off a lot more of the house. The only entrance to the front door is from the driveway right by the garage door and walk across the whole length of the porch, because the door is right in the corner where the gable sticks out. It's hard to even see how you are supposed to get to the door.
So I am finally taking down the green balls (two down and four to go!

So all that brings me to my question. I always tell people "go big" when designing foundation planting. You do not want a narrow strip/ straight row of plants--very boring and unflattering. Given that the house is about 55' across from the driveway edge to the other side, about how deep do people thing would be good? It will be curving front, but just to get a general sense of what I am looking at. The green balls stick out about seven feet from the house. I'm thinking that is about enough but it might curve out a bit more in front of the windows. What do people think? Should I go bigger?
