The Art Of... Indoor Salad Gardening

I have a confession: I've lived in Vermont for more than a dozen years, and I don't know the first thing about gardening. In summer, I'm green with envy looking at friends' Facebook and Instagram photos of their kids frolicking among backyard garden beds, cradling homegrown cucumbers and picking plump tomatoes right off the vine. Every year I think to myself, I'm going to learn to grow my own bounty one day.

  • Growing greens on the windowsill

That idea has yet to germinate. But in February, I took a baby step toward earning my green thumb. My 9-year-old daughter, Mira, and I signed up for an indoor salad-growing workshop at Shelburne Farms. Calais resident Peter Burke — author of Year-Round Indoor Salad Gardening, published in 2015 by Vermont-based Chelsea Green Publishing — taught the class. He took Mira and me, plus several other parent-child pairs, through the surprisingly simple process of growing soil sprouts, which take only a week to mature and can be thrown into salads and stir-fries, used to garnish a sandwich, or nibbled for a healthy snack. There are all different sprout varieties; Burke favors sunflower, radish, buckwheat, pea and broccoli.

The lifelong gardener and father of five adult children started growing sprouts indoors in the winter of 2005, driven by the desire to have fresh salads year-round. Not only does his simple method yield crisp, crunchy greens, but it's cost-effective. In his book, Burke explains that growing your own sprouts costs roughly $2 a pound, whereas buying them at the market can set you back between $10 and $23 a pound.

Burke's motto is, "You can't mess this up." Following his process, Mira and I grew tasty pea shoots on our windowsill in about a week. If even this inexperienced gardener can do it, chances are it will work for you as well.

Supplies for sprouting

For 5 trays of greens:
  • 5 small trays, (3 by 6 inches, 2 inches deep). Half-loaf foil baking trays work well.
  • 1 tablespoon of seeds for each tray. You can purchase them on Burke's website, the Daily Gardener or through Wolcott-based High Mowing Organic Seeds. Make sure you get seeds for sprouting rather than garden seeds.
  • 1 gallon standard potting soil (with no added chemical fertilizer)
  • 5 tablespoons manure compost
  • 3 teaspoons dry kelp meal (find it at your nearest Agway or online)
  • Newspaper (paper towels, napkins or packing paper also work)

Growing Your Greens

Soak: Submerge the seeds in water for at least 6 hours, or overnight. Meanwhile, add 4 cups of water to your potting soil and set aside. Fold newspaper to a size just a bit bigger than your trays. When seeds are ready to plant, soak your newspaper in water.

Sow: In the bottom of each tray, mix 1/2 teaspoon kelp meal and 1 tablespoon of compost. Fill the trays with about 1 1/4 cups of the moistened potting soil. Level the soil, leaving 1/4 inch to the rim. Drain water from seeds, then spread one tablespoon of seeds over soil, so seeds touch but don't overlap (no need to bury them). Press soaked newspaper into each tray so it touches the seeds.

  • Harvesting

Grow: Place planted trays in a warm, dark place — like a cabinet drawer — for 4 days. On day 5, remove the newspaper, water the trays and place them on a well-lit windowsill. Once a day, water with 2 to 4 tablespoons water per tray.

Harvest: After 3 to 6 days, harvest the shoots by cutting the stems with scissors about 1/4 inch above the soil surface. (Radishes are the quickest; broccoli takes the longest. Don't wait too long to harvest or the shoots may become tough or bitter.) Gently wash harvested greens.

Eat: Chop greens into 1/4- to 1/2-inch pieces and toss in a salad, sandwich or stir-fry. Put unused greens in a plastic bag or sealed container and store in the fridge. They'll stay fresh and crisp for up to a week.
