Starting Green Onion Seeds Indoors Vs. Sowing Directly Outside
When it comes to planting green onion seedlings, you have the option to start the seeds indoors or sow them directly outside. Both methods can yield successful results, but they have slightly different requirements.
For those who choose to start green onion seeds indoors, the process begins approximately 4 weeks before the last spring frost date. Starting seeds indoors allows for better control over environmental factors, such as temperature and humidity. Additionally, it provides the opportunity to extend the growing season. To start green onion seeds indoors, use seed starting soil and cover the seeds with about ¼ inch of soil. The soil should be kept moist throughout the growth process, but avoid saturating it.
On the other hand, sowing green onion seeds directly outside is another viable option. When planting outdoors, choose a location that receives full sun. Dig holes spaced 1 to 2 inches apart, deep enough to accommodate the roots of the seedlings. Place a couple of green onion seeds in each hole and cover them lightly with soil. Avoid overwatering, ensuring the soil remains moist but not saturated.

When planting green onion seedlings, there are two options: starting the seeds indoors or sowing them directly outside. Each method has its requirements and can yield successful results.
Transplanting Green Onion Seedlings For Successful Growth
Once green onion seedlings have reached a certain height and are ready for transplantation, careful handling and appropriate techniques are necessary to ensure their successful growth. The timing for transplanting green onion seedlings outdoors is crucial, with a recommended soil temperature of around 55º to 60º Fahrenheit.
Before transplanting, it is beneficial to add compost to the soil in order to provide the seedlings with a head start. When preparing the hole or trench for transplantation, make sure it is only an inch or two deep, as green onions have shallow root systems. Remove the seedlings from their container carefully, ensuring that the roots are undisturbed. Transplant each seedling individually, gently placing them in the prepared hole or trench.
Water the transplanted green onion seedlings well, ensuring the soil is moist but not saturated. Green onions typically need around 1 inch of rainfall or hand watering each week. It is crucial to monitor the soil moisture levels, as drying out completely can be detrimental to green onion growth. However, overwatering can lead to root rot, so it is important to strike a balance.
Maintaining And Watering Green Onions For Optimal Growth
Green onions have shallow root systems, which makes them susceptible to competition from weeds. To help control weeds and maintain optimal growth, consider adding a light layer of mulch once the green onion plants have reached a few inches in height. Mulch provides a protective barrier, preventing weed growth while retaining soil moisture. It is important to ensure that the mulch does not suffocate the green onion seedlings. Leave a small space around the base of each plant to facilitate air circulation.
Watering is a critical aspect of maintaining green onions. They require around 1 inch of rainfall or hand watering each week. While the soil should not be allowed to completely dry up, overwatering should be avoided to prevent rotting. It is best to water the plants deeply and infrequently. Regularly monitor the soil moisture levels, adjusting watering frequency as needed.
Harvesting And Rejuvenating Green Onions For Continuous Supply
The beauty of green onions is their ability to regrow, providing a continuous supply of this flavorful vegetable. Harvest green onions when they are around half an inch in diameter and approximately 12 inches tall. Depending on your preference, they can be pulled from the soil or cut with gardening shears or kitchen scissors.
After harvesting the green onions, the remaining base will continue to produce new green shoots. To rejuvenate the plants, it is essential to leave a small portion of the white stem intact. This will enable the green onions to regrow and provide ongoing harvests throughout the growing season.
Green onions are a low-maintenance crop that generally experiences few problems. However, they can be susceptible to pests like slugs and nematodes, as well as diseases such as downy mildew, rust, and dampening off. Regularly inspect the plants for any signs of infestation or disease, taking appropriate measures to control and mitigate the issues.
Planting green onion seedlings can be a straightforward and rewarding endeavor. By following the step-by-step guide outlined above, you can ensure successful growth and enjoy a continuous supply of this versatile and delicious vegetable.
