Scallions can be grown by the indoor gardener who is an apartment dweller, doesn't have the land necessary for an outdoor vegetable garden, or who just wants to bring some natural greenery inside. Not only do easy-to-grow scallions add some décor to a home, they also are a tasty addition to many dishes. A relative of the green onion, scallions can be eaten either cooked or raw and all parts of the plant are edible, according to patiofarmersguild.com. All materials needed to grow scallions indoors can be purchased at your local gardening center.
How to Grow Scallions Indoors
Fill a shallow planting container with potting soil. Use a vegetable-specific potting soil that contains a fertilizer. The container shouldn't be too big. Scallions have shallow roots and do not need large areas to achieve maximum growth.
Plant five to 10 scallion seeds in the container. Place the seeds 2 to 3 inches apart and one quarter to 1 inch deep into the potting soil.
Water the soil and keep it moist. Don't worry too much if you occasionally over or under water the plant. Scallions are hardy and can overcome too much or too little watering.
Place the container in an area that receives full sun and is free of drafts. Keep the container away from ventilation ducts.
Harvest scallions 100 to 150 days after planting when they are mature. The tops should be 8 to 12 inches tall. Cut the greens with scissors or pick them from the soil by hand.
