Here are the tomatoes that Amy planted a few days ago, before they grow to monstrous proportions by the end of the summer.
From personal experience, I'd expect these to grow big enough you'll never know it was originally four plants instead of one. But we did use MiracleGro once a month, water our garden every day for an hour, and hoe the weeds two or three times a week, so I'm sure that helped.
I hope to take another picture or two during the summer, which I will post here to show their progress. Amy has no idea I'm doing this, but she'll find out soon enough, as she is one of Andy's coworkers.
