That time has arrived for my earliest crops: they need thinning. I sigh, as I am wont to do over this task, and mumble once again, “Isn’t there some way to avoid this fiddly, tedious, extra task?”
Come on, admit it, doesn’t it seem like a make-work project to plant a bunch of seeds, and then, after a few weeks, take a bunch of them back out?
Why not just plant them all at the right spacing to begin with and be done with it, right?
Every year I think this, and every year I talk myself back into doing it the long way. Here’s some of the reasons why.
1. Bad germination. Sometimes only some of what you plant will actually sprout. I hate to break it to you, but there’s a lot that can go wrong before those little plants are even born.Could be heavy spring rains washing out or rotting seeds, dry weather frying them, critters stealing them, less than ideal soil temperature, or just plain bad seed. So you over-plant, improving the odds that you will have enough germinate for your needs, and insuring yourself against empty gaps in your rows or squares (along with the resulting urge to re-seed).
2. Plant strength. Not every seed is absolutely, one-hundred-percent identical. Each might respond differently to the exact micro-climate you place it in. By planting thickly, you can choose those plants that seem the strongest to focus your resources on, discarding those that are weaker– and you do this when they are quite young to give the survivors the best chance and the most room.
3. Nature of the beast. No matter how far apart you plant some seeds, you will always need to thin because the “seed” is actually a seed pod, containing a group of seeds. Beets are a good example. In these cases, just resign yourself to the necessity.
My biggest problem with thinning is this horrid feeling that I am killing tiny bits of life. All that potential! How can I toss it at the compost heap? But the truth is, by sacrificing those little guys, you really are improving the production of the rest. I had two big squares of carrots last year. One I thinned early, the other got pushed to the bottom of the list until well into July. You would not believe the difference in the harvest in those two squares (both seeded and germinated evenly): the first gave me pounds of medium to large sized carrots, the second had lots of tiny ones, the kind that are just annoying to try to clean and prepare.
So away I go, with some good sharp scissors, and weigh my little seedlings in the balance. Those found wanting get a snip right at the soil line (yanking them up is more likely to disturb roots on the keepers).
There is the odd time you might find three really strong, healthy looking specimens grouped too close together. I have been known to dig some up and move them to a more suitable spot, but be warned: only try this on plants that don’t mind root disturbance.
Though I haven’t quit my grumbling about one of my least favourite garden chores, I try to keep as my mantra a little piece of wisdom I heard someone say somewhere, sometime: “I would rather grow a few plants really well, than an acre-full badly.”
