How to Grow Green Onions / Scallions Indoors

Growing Green Onions Indoors

Green onions (or scallions) are a great choice for those who are new to indoor gardening. They are easy to grow and can be used for cooking in so many different ways. For an even easier route, you can also regrow green onions from the ones purchased at supermarkets. Here are our top tips for growing green onions indoors.

Use the Mature Green Onions
As we mentioned earlier, it’s possible to re-grow the green onions you purchase at the market. People who cook with green onions or scallions generally cut off the root end before using the remaining green stalks for cooking or garnishing. Well, don’t throw away the root-end just yet. Place the root-end in a small empty jar with enough water to cover the roots. Set the jar by the windowsill where there is plenty of sunlight and wait a few days. You should start seeing new green shoots appearing from the top of the bulb.

Provide the Right Environment
For those who are starting from scratch, it’s important to maintain the green onion plants in an optimal environment. This typically includes an area of the house that gets plenty of natural sunlight, a fairly neutral soil pH between 6.0 and 7.5, and the addition of soil supplements like premium compost.

Scallion Watering Needs
Scallions or green onions are perfect for indoor gardening beginners because they are relatively low-maintenance. Generally speaking, green onions only require about an inch of water per week. We suggest you use the finger test to figure out the appropriate amount of water to give to your indoor plant. All you have to do is to stick your finger in the soil (about second knuckle deep). If the soil at the tip of your finger feels dry then you know it is the right time to water your green onion plant.

Keeping Pests Away
Pests such as thrips and aphids are pretty rare, especially for homegrown green onion plants, but it’s always good to be on the defense. You can prevent pests from attacking your green onion plant by 1) ensuring that the soil isn’t too damp 2) checking the plant foliage regularly and 3) only using high-quality soil and fertilizer.
