How To Grow Green Onions And Use Them Over And Over And Over

How to use the same green onions over and over and over 2

Indoors, outdoors, it doesn’t matter where. You can regrow your green onions and eat them too. So the question is, how many salads can you eat realistically? Throw a number out there and we’ll do some math.

A green onion is a little bulb with roots that grows this stalk of leaves that humans find delicious. So it’s as simple as this: cut the stem off an inch from the roots, and either stick it root-side-down in water until it sends up shoots, or plant them so the bulb is 3/4 inch below the surface of the soil. It will take another few months to grow back to its former glory.

This is where the real math comes in. If I like to use one green onion per week, how many do I need to have growing in order for this to be sustainable?

The answer is the number of days to maturity between when you cut it and when it is ready to harvest again, divided by 7 days in a week.

90 days to harvest / 7 days = 12.857 green onions if you like having one green onion shoot per week. The rest is multiplication. Better round up just to be sure.

When Should I Plant?

Onions grow better in cooler weather, so plant from seed in mid to late September in Tucson. Higher elevations than 2,400 feet can do this earlier. Albuquerqueans (Albuquerquites?).. people who live in Albuquerque at 5,300 feet can plant them from seed at the beginning of August. Check for local planting calendars relevant to your area, and follow those instructions.

Onions are one of the exceptions to my rule about only planting from seed, anything with a short root system that doesn’t mind being uprooted, like bulbs, is A-OK. Seeds are still cheaper, but that’s up to you. Seed onions come as smaller bulbs, and are a good, relatively cheap way to get ahead of the curve on planting these delicious veggies.


Technically, here in Tucson, you can grow green onions all year round, as long as they are not sitting in direct sunlight during the hottest part of the day.

Use garden bed mix planting soil. Straight compost usually works amazingly well if you can find it. If it is too compacted after watering, they’ll have a hard time, so you’ll want to add a little sand to the mix.

Water every other day during the hottest months. In winter the soil retains moisture easily, so you’ll want to monitor it and water only when really needed.

Now that you know how to grow them, you’ll be able to wow your friends and your wallet. Happy eating!
