Where can I plant my asparagus patch? [View all]

We're going to bite the bullet this year and start an asparagus patch even though it will be at least two seasons before we can enjoy the yummy fruits of this year's labor. Now we just have to decide where this will be. So few options, none of them very good!

Option A: In the front, under the big, old pine tree
I know, I know, asparagus needs full sun! But this space is SW facing and gets at least 8 hours of sun from early June through September. The drawback about under the pine is that asparagus needs a good 12" bed. I don't want to dig down a foot and damage the pine roots, but then, I don't want to build a foot high bed over the roots and damage them from lack of oxygen. Could I dig down 6" and put a 6" raised bed on it without damaging the pine roots?

Option B: Along the north side of the driveway
This area is very arid, incredibly sunny and drains very well. The biggest drawbacks are lack of easy water access (too far away from any outside spigots for any hose to reach it so it would all have to be hand-watered) and also, it's kind of near where my SO parks (so exhaust fumes - ick).

Option C: Someplace else in the yard
The problem with anywhere else in the yard is dogs and their pooping or play spaces/access to other raised beds/too much shade.
