For this purpose you need the following things:

  • High-quality seeds from a gardening store or local nursery.
  • A small pot that has drainage holes.
  • Potting mix

SOWING OF SEEDS

> Fill the pot with potting mix after sowing the seeds, cover the seeds with ¼ inch of seed starting formula. You will get all the information about sowing the seeds on the packet. The packet has all the instructions and tips regarding sowing the seeds.

> Keep the soil moist and the temperature of the soil must be about 60 to 65 degrees Fahrenheit.

> After 7 to 14 days you will see the seedlings will start emerging from the soil.

PREPARING SITE AND SOIL FOR RAISED BED FOR TRANSPLANTING SEEDLINGS

SUNLIGHT

The location and size of a raised bed are very important. Choose the location for your raised bed where your plants get another full sun exposure. 6 to. Hours of sunlight are very important for green onions. 

SIZE

The width of the raised bed must be 2 to 3 feet. The wider bed can’t be managed easily. The middle plants will be neglected which is not good for getting a healthier crop of green onion. Weeding and harvesting become easier with the standard size of the raised bed.

SOIL

You should provide the best soil conditions to your plants so you will get fresh and robust growth. Rich compost will deliver all the basic nutrients to the soil. With the addition of compost, your soil becomes fertile. 

If you are using garden soil then the pH of the soil must be between 6.0 and 7.0. Well-drained soil is preferred and you should avoid pooling or soggy conditions. 

Here are simple steps if filling your raised bed. 

  • It is suggested that you should use high-quality soil in your raised bed and spread a 4-inch layer of compost on the surface of the soil. You can buy ready-made compost from any garden store or nursery or create your compost by using kitchen waste. 
  • Now on the top of the layer of compost spread a thin layer of blood meal. It will work as an amendment for the soil. 

MAINTAINING GREEN ONIONS

When your green onions are sprouted from the seeds then you can easily maintain your crop. Well-established plants of green onions need no special care. 

Watering: Water your green onions plant one inch per week. In a raised bed soaker hose system works great for irrigation purposes. 

Mulch: For retaining the moisture within the soil you can spread a layer of mulch on the top of the soil around the green onion plants. It will also help to surpass the weeds which are unwanted plants. 

Weeds steal all the nutrients from the soil and your plants have to compete for nutrients. You can get rid of this problem by using mulch.

Keep your soil moist but not soggy. Your fingers work great for checking the dryness of the soil. If your finger feels that the soil is dry then you should water your plants if it feels moisture then you should not water the green onion plants. 

You should perform this finger test once a week to check the moisture level in the soil. During the rainfall, you can reduce the amount of water. But on sunny days, especially in the summer season, your plants need more water. 

It means the amount of water depends upon the weather condition. So you should increase or decrease the water according to the climate situation. The dry soil can result in the dryness of the bulbs of onions.

COMMON PESTS AND DISEASES

Following are the pests and the diseases which affect the growth of green onions.

CUTWORMS

Cutworms cut off the seedling at the soil level. For this problem, you should keep a paper cup collar around the base of the green onion plant. These insects affect young seedlings. The other way of controlling them is by handpicking.

ONION MAGGOTS

Onion maggots attack the bulb of the green onions rather than the leaves. As a result, the entire seedlings will eventually die. The best solution to this problem is that you should pull all the plants and use the greens to destroy the rest parts of the plant. Crop rotation is another solution to this problem.

THRIPS

Due to these tiny insects plant develops silvery-white streaks. You can use a heavy blast of water with the help of a garden hose to get rid of this problem.

DAMPING OFF

If you start green onions from the seeds then you will face the problem of this disease. The symptom of this disease is that the seedlings suddenly wilt and die for no clear reason. 

This disease is caused by a fungus that causes abundant moisture. You should avoid overwatering and the use of a high amount of nitrogen fertilizers.

DOWNY MILDEW

The symptoms of this disease are whitish-grey patches on both sides of the leaves. Rotate crop is the solution to this disease. Avoid overwatering and provide an adequate amount of air for the breathing of your plants.

PINK ROOT ROT

In this disease, a fungus attacks the roots of green onion plants and turns them into light pink. The plant will be affected by this disease due to the deficiency of nutrients and drought due to which roots are not able to take up water and nutrients.

HARVESTING GREEN ONIONS

The best time of harvesting green onions is when they are young because at this stage they are very tender. Generally,  green onions are ready to harvest within 70-90 days.

When you see the size of green onions is 6-8 inches tall and the bulbs have begun to swell then this is the right time of harvesting. Just gently pull down the tops of the green onion. 

  • You can also regrow the green onions. For regrowing purposes, you can leave a one-inch part above the part of the green onion when you are slicing green onions for your favorite dishes. This section can be used for regrowing purposes. Just place this root section about 1 inch deep in the soil of your raised bed. After placing the root lightly cover it with soil. Remember the root side should be down in the soil.
  • Within a couple of weeks, you will see these sections will re-sprout. You can repeat this process several times by using the same section of root.
