How to Plant Onion Plants in Pots/Containers

Instructions

Buy onion seeds from your local store, and while you are there, a pot or container with holes at the bottom. You will need good fluffy potting soil with fertilizer; otherwise, you will need to get some fertilizer. With everything on the list, you are ready to start the onion planting process.

Here are eight steps on how to plant onions in a pot or container:

Step 1. Germinate Onion Seedlings

Before starting the planting process, you must prepare and germinate the seedlings. In germinating, you must place the seeds in water for about eight to twelve hours. The onion seeds will absorb the water, resulting in the seed cells' rehydration and expansion. Germination is a good idea to speed up the growing process.

Step 2. Obtain Pot or Container with Bottom Holes

Your onion seedlings need a pot or container with proper soil to grow in. Find a pot or container at least ten inches deep and ensure that it has holes at the bottom for proper drainage before you fill it with soil. Drainage is very important when you plant onion seeds because it allows water to drain freely through the soil to ensure adequate air is available for the roots.

Step 3. Add Soil to Pot or Container

After your onion seedlings germinate and your pot or container has adequate drainage holes, it is time to add the soil. You cannot use any soil for your onion seeds and must ensure that the soil or potting mix is fluffy. If the soil or potting mix is fluffy, it will retain enough water to keep the soil wet so the seed can absorb it and continue growing and drain enough water to prevent the seeds from rotting.

Fill the pot or container with your potting mix and ensure you fill it at least 95% to give the roots enough room to grow deeper if necessary. As mentioned in step two, the container or pot must be at least 10 inches deep to give enough space for the roots to go.

Step 4. Add Water to the Soil in Pot or Container

The container filled with the potting soil will likely be too dry, and you mustn't plant the germinated seeds at this point. Take another bucket and fill it with water, or use a watering can if you have one. If your potting soil does not have organic fertilizer, now is a good time to add some before you add the water.

Add water to the potting mix in the pot or container you filled and ensure that it mixes well until the soil is thoroughly soaked. If you have a small garden fork, you can use it to ensure it is mixed to the bottom; otherwise, your hand will do just as well. Before you can go to the next step, the soil must be completely soaked.

Step 5. Plant Germinated Onion Seedlings

You can continue planting with the soil in the pot or container thoroughly soaked with water. The number of onions you plant will depend on your pot or container size, but you mustn't plant them directly next to one another. Onions need space to grow, and planting them too close will result in small onions and even losing a few during the growing prosses.

If you have a tool to make the holes for the germinated seedlings, it is a good time to bring it closer, but if you do not have a tool, your finger will work just as well. Make a quick calculation where you want to plant the seedlings and push a whole with your finger or the tool into the wet soil. You must not make too big holes and bury the seedlings completely because half of the onion must still be visible.

Step 6. Completing the Planting Process

The onion planting process is complete with the germinated seedling in their place and sticking out halfway. If you intend to harvest some onions early for cooking, you can plant them a little closer because they do not have to reach their full size, but if you want to get them fully grown, you must consider the spacing.

Remember that the onions need water regularly to maintain moisture; otherwise, they will dry out, especially if you use a small pot or container.

Step 7. Soak Onion Seedlings

With the planting process completed, take the water bucket or watering can and soak the onions one last time. Do not worry about giving it a little extra water because your potting mix will absorb what it needs, and the rest will drain if it is of good quality. After you give your onions a final watering, they need a good spot in the sun to start growing and regular watering until it is ready for harvesting.

Step 8. Place Pot or Container in Sun and Water Regularly

Onions grow fast, and you should see their tubular leaves growing within three days. If you water it regularly and give it enough sun, your onions will show fast growth within the first three weeks. To give your onions the best chance of becoming big and healthy, you must consider adding liquid fertilizer or fertilizer to the water before you wet it after a few weeks.

After a month, you can cut some of the leaves for a salad, stew, or soup, and if you want to enjoy its fullness, it will take about ninety days to reach maturity. Planting onions is easy; hopefully, you will use these steps every time you decide to plant your next batch of onions.
