Green Thumb Fail

Every time I look out the window at the small(ish) fenced garden, I feel a massive amount of FAIL. I didn't maintain it this summer, due to incubating TinyDoom! and, I will admit, a complete disinterest in weeding, dirt, and the Great Outdoors in general. This is two part vicious allergies and one part of extreme laziness.

Which begs the question... what should I do with the flower beds this coming year???

Five years in the house, and I _know_ that despite my best intentions and my haphazard attention, the garden will be neglected. Should I dig out all the dirt and spread more gravel inside the enclosed/fenced space? We can't tear out the fence completely, because it keeps people from driving over the septic access thingamajigs. I'd put an above-ground pool in there, but that's not a good idea with the septic tanks just under (duh.) So what to do. What to dooooooooo?!

Koi pond? (Too much maintenance and we've killed four fish in bowls inside in as many years.)

Rock garden? (Tempting!)

Oversize torches and signs that read "This Way To Mordor"? (Heh.)
