Start an easy salad garden without planting a single seed! 

Everybody needs a food garden. No matter how small your garden and meager your harvest, the fresh food that you produce there will will be tasty and nutritious. It will connect you with the natural world.

Okay, maybe you don’t have much or any outdoor space. Or, perhaps it’s not spring and seed packets are hard to find. But you could also start an indoor salad garden by using the produce from your local grocery store!

Stumps, Stems, and Roots

Begin in the produce aisle of your local supermarket. Toss in a couple of bunches of celery and and couple of heads of Romaine lettuce (or other lettuce attached to an intact base), a few small onions, and several packages of the fresh herbs that you use most: basil, oregano, mint, thyme, sage, rosemary. You’ll want stems 4 to 6 inches long.

Head for the organic section to collect a couple of sweet potatoes, a few beets, a few large radishes, and a few unwaxed turnips. Why organic? You’ll want your roots to sprout, and many conventionally grown root vegetables have been sprayed to prevent sprouting.

These vegetables comprise your garden starters. The cost is negligible, because you get to eat a lot of what you’ve bought.

Gardening Supplies

You’ll also need:

  • Containers for your plants. Your imagination is the limiting factor here. The only requirements for a good plant container: It must hold soil, drain well, and have contained no toxic or hazardous materials. Coffee cans, plastic buckets, galvanized tubs, all with drainage holes punched into the bottom and sides; clay pots of any size or shape; burlap bags; wooden crates; polypropylene shopping bags; sandbags; window boxes; cut-away soda bottles; a length of PVC pipe with planting holes cut out; pieces of roof gutter with holes drilled in the bottom.
  • A bag of sterile potting soil. Don’t use ordinary topsoil. It’s too heavy for indoor plantings and may contain weed seeds, spores of plant diseases, and insect pests.
  • Some form of liquid fertilizer. You can find many complete liquid fertilizers at garden centers. I use a commercial product containing a mixture of fish emulsion and seaweed extract. (It’s very smelly, but the smell dissipates within a few hours.) Use any fertilizer according to package directions.
  • Sunny windowsills or a full-spectrum fluorescent light fixture or two. Although leafy crops don’t need as much sun as those that flower and fruit, your growing crops will still need a few hours of sunlight each day. Indoor growers have developed some truly ingenious ways to make the most of what light they have.
  • A watering can and maybe a plant mister. You can even make your own waterer from a plastic jug. A repurposed spray bottle or one from the dollar store will work fine for misting.

Growing salads and soup greens

  • Celery from a stump: Just cut the bottom 2 inches from a bunch of celery (refrigerate the stalks for later use) and “plant” it, root side down, in a saucer of water or an inch or two or pot of moist sand or potting soil. Leaves, then tender stalks will slowly emerge from the center. When the stump is well rooted, transplant it into a larger pot. You’ll be able to harvest tender stems and leaves for soups and salads for many months.
  • Romaine or other lettuce from a stump: Follow the same procedure as for celery. Pick the outer leaves as they mature, leaving new leaves to grow from the center.
  • Clone new basil, sage, mint, thyme, oregano, or rosemary plants: Remove lower leaves from the stems of fresh herbs and set the stems in water. Keep the water fresh. Once your stem has a good set of roots, you can plant it in potting soil in a suitable container. Keep the plants growing in a sunny windowsill or under a full-spectrum fluorescent. Trim “branches” as needed to clone new plants.
  • Sweet potato foliage: Unless you often shop at ethnic supermarkets or do a lot of Asian-style cooking, you may not know that sweet potato foliage is edible, tasty, nutritious–and makes a gorgeous, irrepressibly vining houseplant. Note: Don’t try this with regular potatoes, whose sprouts and leaves are poisonous. Slice the sweet potato root in half or leave it whole. Use the toothpick method to suspend your sweet potato in a jar of water with the cut side under water until it begins rooting and sprouting. Each little “eye” above the water level will grow a new slip that you can remove and place in water to root. You can even grow tubers from your rooted slips in a large polypropylene shopping bag or other suitable container if you have enough space.
  • For fresh green onions: Cut a bit of the root ends from cooking onions (leaving an inch or so of flesh) or from a bunch of scallions and plant them in a pot of moist growing medium. You can even plant a whole cooking onion that’s begun to sprout. Trim blades for use as the new scallions reach harvestable size.
  • To grow beet, radish, or turnip greens: Follow steps similar to those outlined for sweet potatoes. You can use the toothpick-suspension method or plant your cut roots in a large, shallow bowl with water and clean sand or some some small rocks. Remove the largest outer leaves (if any), cut off about a third of the root, and set the flat cut end in the bowl. Once each root grows a healthy set of roots and leaves, plant it in a container of potting soil. As the new plant grows, harvest the outer leaves for salads or cooking; leave the center leaves to grow.

I've never tried this, so I

Coddess, I have never tried this, so I do not know for sure, but given abundant, healthy roots and foliage, I assume it could work. Why not give it a try and let us know?

when growing turnip greens

when growing turnip greens from a sliced off top placed in a bowl of water and later planted into a pot, will the plant eventually flower and makes seeds?

Regarding turnips

According to a book I have called "Don't throw it, grow it" if kept moist leaves will appear first, sometimes followed by flowers.
