How to Grow Green Onions in Containers: Planting, Care, Harvesting, Storing and Solving Pest Problem

Green onions are versatile vegetables that can be grown in containers. I had to include this guide because they are easy to plant and care for, and can be harvested at different stages of maturity, depending on your needs.

In this blog post, I will discuss how to grow green onions in containers, from planting to harvesting to storing. I will also cover common pest problems and how to solve them.

1. Planting green onions in containers

Start by filling a container at least 6 inches deep with well-draining potting soil. Then, place your green onion bulbs about 1 inch deep and 3 inches apart, making sure the root side is facing down.

Water thoroughly and place in a spot with at least six hours of sunlight a day. Keep the soil consistently moist, watching out for any yellowing leaves that may indicate overwatering. In just a few weeks, your green onions will be ready for harvest - simply cut off what you need and the rest will grow back.

2. Care for green onion plants

When choosing a container, make sure it has drainage holes at the bottom and fill it with well-draining potting soil. Place the container in a spot with partial sunlight and water consistently, allowing the soil to dry out slightly between waterings.

As the plants grow, use scissors to trim off the green tops for use in cooking. Every few weeks, give your green onion plants a fertilizer boost to ensure continued growth.

3. Harvesting and storing green onions

When the plants reach about six inches tall, it's time for harvesting. Cut the onion tops at a diagonal just above where they meet with the soil, leaving some of the white base intact so that new shoots can continue to grow.

The green onions can then be stored in the refrigerator, wrapped in a damp paper towel and placed inside a plastic bag, or even frozen for longer term storage. Beyond simply snipping off what you need for any given dish, there are endless options for incorporating this versatile vegetable into your cooking.

Use them in stir-fries or salads, blend them into soups or dips, or grill whole green onions for an extra touch of flavor on skewers or kebabs.

4. Pest problems and solutions for green onion plants

Green onion plants can also attract their fair share of pests. Potential pests include aphids and onion thrips, both of which can be controlled by using Neem oil or releasing beneficial insects such as ladybugs. Dish soap, water or horticultural oils are also effective at eliminating aphids.

To further discourage pests, it's important to keep the gardening area clean and remove any damaged or diseased plants immediately.

The most important thing is to monitor your crop and inspect it regularly for signs of pest infestation. If you catch the problem early enough, you can often eliminate it entirely without resorting to chemical treatments.

Green onions prefer a sunny location and well-drained soil. They can be grown in containers or directly in the ground. When planting green onion seeds, be sure to plant them in loose, fertile soil about one inch deep and three inches apart. Once they germinate, thin the seedlings so that only the strongest plants remain. Green onion plants need consistent moisture to grow well, so water them regularly. Allow the soil to dry out slightly between waterings. As the plants grow, use scissors to trim off the green tops for use in cooking. Every few weeks, give your green onion plants a fertilizer boost to ensure continued growth. With proper care, these tasty greens will keep producing for months to come.

Can green onions be grown indoors?

Green onions can be grown indoors, although they will need a sunny location. Place the plants in a south-facing window, and water them regularly. Be sure to provide good drainage, as green onion plants are susceptible to root rot. You can also grow green onions under grow lights if necessary. Keep the lights on for 14-16 hours per day, and maintain a temperature of 70-75 degrees Fahrenheit.

What are some common uses for green onions?

Green onions can be used in stir-fries or salads, blended into soups or dips, or grilled whole for an extra touch of flavor on skewers or kebabs.

When substituting one for the other, keep this in mind and adjust the amount you use accordingly.
