Until recently, I'd never been able to make onions grow. I'd have one start sprouting in the kitchen...oops...and it would rot out as soon as I tried to do make it grow. I finally figured out how to grow them using kitchen scraps (check out my article How to Grow Onions from Kitchen Scraps in 3 Easy Steps to learn how!)
Onions are fun to grow, make neat vertical stems and tall blooms, and are surprisingly versatile. I also love that they can be grown in pots and garden containers, which make them ideal for apartment and balcony gardeners.
In order to grow thriving onions in containers, keep these helpful tips in mind:
- Choose a pot that is at least 10 inches deep. This will give the onions plenty of room to root downward and absorb nutrients.
- Soil should be well-drained. If you're using standard potting soil, I suggest mixing in some sand in order to improve drainage.
- Plant onions about 3 inches apart from each other. This will give the bulb enough room to expand into a full onion without them bumping into each other.
- Onions love sunlight. Place the pots in your sunniest location. They need full sun, the more the better.
- Keep your soil moist, but never soggy. Water thoroughly, and when the soil begins to dry out, water the onions again. The onions will be juicy, and that juiciness comes from consistent watering.
