Dave, I planted mine as close to the wall as I was able to. In fact, for the first few years I grew them as Espaliers then, as per usual, I got too busy (lazy) to keep up with it. That was how I was able to learn that they will self-prune from the cold as they grew too far away from the house. I think mine are planted about 6 foot apart- this has created a wall of Satsuma. We have Arctic Frost at the garden center that I work for but I will not bother with them. Got quite enough Tangerines each fall as it is!
One thing I like about growing them along the wall is that when it rains, it runs off the roof right into the trees. Oh, and of course, when they bloom (April) all the windows on that side of the house have the wonderful scent drifting in.
You know what is funny? My bees have only a passing interest in the blossoms! Perhaps it is because there is such an abundance of other stuff blooming but still...I always figured bees would go nuts for Citrus blossoms!
