One thing I've learned about myself over the past 6 years of home ownership, is that I basically despise yardwork. There are tasks I don't mind but still don't like (trimming bushes), tasks I hire out (lawn mowing), and everything else (weeding and so on) I would just rather not do. I see myself looking for townhomes and/or condos in the future, to avoid a large lawn to take care of. :)
About the only thing I do "enjoy" is growing tomatoes. My friend Mai gave me this plant for Christmas, and it has reliably produced a handful of tomatoes every 4 to 6 weeks. That isn't enough to feast on, but they do make an occasional salad extra tasty. All I have to do is water it and shovel a bit of fertilizer/topsoil in now and then. Easy enough even for me to do!
Maybe I'll branch out into growing simple herbs or green onions - edible plants that do well in pots.
