When the nice, veteran gardener from the adjacent lot recommends you thin your carrots, it's best to do it BEFORE going on a two week vacation and then being too busy for another week. Let me tell you why: Carrots are not meant to be a bush plant, but when you use square foot gardening and plant 2...6...8... seeds in a hole that's more or less what you'll get. Lesson learned. Or maybe the real lesson is not to plant that many carrots in a hole in the first place. Carrots get pretty cozy there in their little holes. When they're packed in their like sardines they twist around each other and aren't so inclined to willingly be removed from their home. Plus it's very sad to see the little, teeny carrots go to waste.
Perhaps there is an even more fundamental lesson to be learned: Nature knows what it's doing. Trust it. When we were planning out our garden we tried to do some research and just got overwhelmed with what to plant next to what and in which kind of soil and on and on. We decided we'd just roll the dice and not worry about all the finer details. Good choice. We've got a pretty amazing earth here. It knows what it's doing. I don't have to plant a zillion seeds in each hole to ensure that one sprouts. Just one. Sure some of them won't work out, but plenty will. I can put that teeny little speck in a hole and it will turn into FOOD. That's amazing.
So maybe we still have a thing or two to learn about gardening. Maybe it's beginner's luck. Maybe someday we'll earn our green thumbs. In the meantime, we'll just enjoy the fruits (or, in this case, vegetables) of our labors.
