Hello and welcome to HealthyHouseplants.com, where you learn all about gardening in the great indoors. Today, we’re going to talk about growing green onions indoors, which is really fun. Today’s video is sponsored by our Amazon affiliate link, which you can see below.
Growing green onions indoors is enjoyable and easy, and it’s so convenient to have them ready when you need them for cooking. I love this method because, most of the time, unless a recipe specifically calls for a cup or more of green onions, you don’t need a large bunch from the store. Often, you end up with more than you need, which can go to waste in the compost or even the trash. Growing your own lets you have just the amount you need.
Here, I have a green onion planted five days ago, and you can already see how nicely it’s coming up. We grow them from the bulbs, like these red and white onions. Outdoors, in ideal conditions, these would grow into full-size onions over several months. However, indoors, it can take just a few days to have green onion sprigs ready to use. For instance, I could clip a bit tonight for a salad if I wanted.
These bulbs look like little onions. The red bulbs have a purplish tint, while the white bulbs are pale. This particular green onion was planted a couple of months ago, so it has grown long and a bit leggy. I allowed it to grow this way to show what happens when you let them continue to grow. You can let them grow long or harvest them earlier—either way, they’ll taste great.
When ready, simply harvest by cutting the green part like you would with store-bought green onions. At this stage, you can also use the whole stalk, including the white part at the bottom, which is very flavorful. Growing indoors lets you pick just what you need, whether it’s for a salad, stir-fry, or omelet.
Now, let me show you how to plant them. I’ll add a few more bulbs to this container, where there’s space. This method is great for continuous harvesting. Planting in succession means you can have some growing at different stages, so there’s always fresh green onions available when you need them. I like using Pro Mix soil, which is lightweight yet retains water well. Water retention is essential, but you also need good drainage.
When planting, make sure the root side of the bulb faces down, and press the bulb into the soil. You can see that some of the bulbs already have a small stalk sprouting—these will grow more quickly, so plant them first. There’s not a big flavor difference between red and white bulbs; it’s mostly a matter of preference.
Push the bulbs into the soil, leaving the tops visible. Then, fill in with more soil, keeping the stalks above the soil level. If there’s no stalk yet, leave the top third of the bulb showing. For bulbs with a small stalk, bury the bulb just up to the base of the stalk.
For best results, you can add a half-strength granular fertilizer to the soil according to package directions. Keep the soil moist but not soggy, and make sure the pot is not sitting in water, as this can lead to rot. Green onions need bright light, so if you lack natural light, consider using a full-spectrum grow light. Position the plants under the light for balanced growth. If growing by a window, rotate the container every few days for even growth.
Green onion bulbs are generally available in late fall through early spring at nurseries or online. Store them in a cool, dry place to prevent early sprouting. If they do start to sprout, plant them right away, as they will grow quickly. However, avoid using bulbs that have become mushy, as they are past their prime and won’t grow well.
That covers the basics of planting and growing green onions indoors. Thank you for watching, and enjoy gardening in the great indoors! Remember to like, comment, subscribe, and share this video.
