Another consideration is water supply - how close is the nearest water faucet to that area you want to grow?
That's a good point, especially with tree roots actively sucking water away from your bed.
However, if you don't mind running a 1/2" or 3/4" irrigation line out to the bed, you can have as many spigots near the bed as you want: enough for driplines, sprayers, or hand-watering nozzles on garden hoses.
Those lines are surprisingly cheap. If you pay for your water, the savings in water usage from drippers on a timer might pay you back for the irrigation gadgets in just a few years.

1/2" mainline $16 / 100 feet - - - up to 240 GPH = 4 gallons per minute
3/4" mainline: $32 / 100 feet - - - up to 480 GPH = 8 gallons per minute
