So, I guess it goes without saying that this didn't happen. The burst pipe was not where we thought it was, so I was not able to get someone else to dig up that part of the yard for me.
I am ignoring everything everyone said on Page 1 of this thread and growing a container garden. I've been doing a lot of reading on gardening and I have come to three conclusions:
1) 75% of my yard is unusable for gardening because of too much shade, and another 20% is unusable because my kids play in it. My yard only has about four square feet of usable land in a place that gets enough sun, and I would have to spend one weekend clearing out the overgrowth, another weekend building raised beds, and a third weekend prepping the dirt and actually planting anything. Even if I had three weekends in a row to spare -- which I don't -- I wouldn't be able to get anything in the ground in time for the start of the growing season for most of the things I'd want to grow this spring. And, that's a lot of work and expense up front for a hobby I'm not certain I'm going to stick with.
2) The best sun in my whole yard is right between the swing set and the trampoline, which is a no-go. But the second best sun is up on my deck, and I have a corner that would be lovely for a triangular arrangement of pots and planters in different heights.
3) While it seems like container gardens are a lot more work, it seems that (based on my reading) in-the-ground gardens are a bigger up-front investment of time -- preparing the soil, planting, hoeing, weeding, etc. -- while container gardens take more day-to-day maintenance -- more frequent watering and pruning. I don't have three weekends to kill preparing my yard, but I do have half an hour three or four times a week to take care of some plants on my deck.
So for me, I think containers are the way to go. Here are some pictures of my yard so you can see for yourselves. It's cloudy today, so you can't really get a sense of how shady things are back there, but take my word for it -- most of the yard is shaded for the majority of the day. (My front yard is even worse -- I have solar-powered lights around my front walk, and they are supposed to run for 8 hours on 2 hours of charging -- during the winter they run for maybe 30 minutes after dusk; in summertime, about 2 hours.)
So I am looking into vegetables (which are much more interesting to me than flowers) and tying to figure out what I could plant that will withstand our hot summers and isn't already past planting season. (Cool-weather plants, like lettuce, have to be started indoors around the beginning of February here because our spring is so short.)
Anyway, this is my latest obsession, so I thought I would resurrect this thread so that those of you who couldn't care less can ignore it.
