How to Grow Potted Scallions

Cut off the end of a green onion, or scallion, leaving the end of the bulb with the roots intact. The ends should be about an inch in length.

Place potting soil into your small pot; mixing in compost is an option, but is a matter for your discretion. Poke a shallow hole into the soil with your finger, just deep enough for the roots of the scallion bulb. If you're planting multiple bulbs, space them approximately 2 to 3 inches away from each other. Insert the bulbs, roots first, into the holes. Approximately half an inch of the scallion should protrude above the soil.

Keep the soil moist by watering your scallions at least three times a week. The soil in pots can dry out very quickly, so you must carefully monitor the soil for moisture. Place your pot in a sunny area and allow the bulbs to grow. Scallions thrive in full sunlight and in temperatures between 65 and 86 degrees F.

Cut off the growth when your scallions have reached a sufficient length, but leave the bulb in the soil. A typical scallion bulb will regenerate multiple times; after four regenerations it may be necessary to replace the bulb, but of course that depends on how well your bulb is doing and the quality of the scallions produced.
