First two blueberry bushes are in!

Yesterday afternoon, The Boy and I got the first two blueberry bushes in the ground.  As with the apple trees, the plan is to have the earliest blooming plants closest to the house with the sequence of blooms heading east-bound.  The rationale is that as each new set of plants begin to flower, they can be pollinated by the previous plant in the series.

I currently only have four blueberry bushes (represented by the blue circles), but will leave some space for others in case we care to add more. 

In doing reading about spacing, I was surprised to find that it's recommended to have the bushes very close together.  A common reference of 6' apart was mentioned.  I would think that that would lead to there being issues with fungal growth.  Regardless, I have the first two spaced 6' apart.

I also couldn't find anything about how close (or far) to space them from other plants.  I ended up planting them 10' from the apple trees.  Considering the tallest blueberry is expected to be "up to 6' tall" and the apple trees should be at/under that, I figured that would be a safe distance.  If I'm wrong, I'll have to trim and/or transplant the bushes.

I need to figure out where I want to plant raspberries.  I'm leaning toward putting them between the blueberries and walnut trees.  While additional blueberries may be okay at that distance, the fact they don't like the juglone exuded from the black walnut makes me a bit nervous.  From what I've read, that distance should be okay, but perhaps not.  I'd rather not chance it.

Unfortunately, I've also read that certain varieties of raspberries are intolerant to juglone.  Fuuuun.....
