Start a windowsill farm, with microgreens

Either winter makes me hungry for fresh vegetables or the seed catalogs do. Either way, every year around this time I decide that this is the year I will grow vegetables in the garden. For real — not just what comes up in the compost pile. I’m forgetting that I did plant kale, cabbage, lettuce, and basil last year and the woodchuck ate it all down to nubs. Which is the same thing he/she did the year before that. And the year before that. And so on. Or else it was the bunnies.
Every year I think I (meaning my carpenter) should build a raised bed tall enough to keep critters out of the veg. And every year so far I have not decided before spring planting where to put it. Nor have I bothered to buy the lumber or stockpile enough soil to fill it.
I’m guessing that once I decide where it goes (in full sun somewhere near the kitchen door) it will need to stand a good 18” high. The other option I have is to surround my vegetables with fencing. Eight feet high is about right to keep deer out (it’s probably only a matter of time before they wander every Bristol street as freely as gulls do), but bunnies and woodchucks are tricksters. To deter them, a much shorter fence will do as long as it’s made of an unchewable metal mesh and is set deep in the ground. And if I really want to give those guys a challenge, the bottom of the fence should probably even curve outwards a little. I am a lazy McGregor, though, and that’s much more digging than I’m usually inclined to do. Are fresh homegrown vegetables worth it?
Probably. Everyone says so.
To find out, I’m going to start by growing microgreens. (I’ve said this before…) All of my favorite seed companies, like Renee’s Garden, John Scheepers Kitchen Garden, Botanical Interests, and Johnny’s, just to name a few, have done the hard work of combining seeds that sprout at the same time into blends with flavor profiles ranging from mild to spicy. Botanical Interest’s seventeen green “Sassy Salad,” which includes arugula, nine lettuces, two mustards, Swiss chard, endive, spinach and bok choy, falls somewhere in the middle. Sounds delicious.
If I supply enough water to keep the seeds and starter soil moist but not boggy, and put them in a windowsill-full of daylight, I should have at least one meal’s worth of tiny bite-sized but intensely flavorful and nutrient-rich salad garnish within two weeks. Maybe two or three meals’ worth depending on the size of the container (ironically, a store-bought salad mix box would be perfect with a few holes punched in the bottom for drainage) and my dinner party. Set inside a cachepot, a mesclun mix might even look as handsome as a houseplant as soon as it gets going and before I eat it up. The seedlings only need to be grown as far as their first set or two of true leaves before becoming supper so the trick is to have several packs growing at once but staggered in an endless succession.
This will be a good test for me. I figure if I become a successful windowsill microgreen farmer, it will be a slippery slope to wanting some of the same vegetables to grow to maturity outside. Maybe it’s time I finally find a place for that raised bed.
