Types Of Onion Seeds To Plant

There are numerous kinds of onion seeds to plant, but for specific reasons, one of the most common ways farmers think about onions is usually by color, whether red, blue, or yellow. 

In contrast, today, the climatic conditions have changed, but one thing is sure, all types of onions have something in common.

Furthermore, onion seeds are divided basically into three different categories, and these categorizations are based on the amount of sunlight they need for adequate growth and development.

They are;

  • Long day
  • Neutral day
  • Short day

1. Long-day 

This is one of the first categories of onion seeds based on the amount of sunlight needed. Some of the popular onion seeds that belong to these categories are the:

  • Yellow Spanish
  • Red Wethersfield
  • Walla Walla
  • Yellow Gold

To mention but a few. They require at least 14 hours of sunlight a day, and anything below this will most likely harm the onion seed

2. Neutral Day

This is the second category of onion seeds based on the sunlight needed for adequate growth and development. Some examples of onion seeds that fall under these categories are;

  • Candy 
  • Red Stockton
  • Sierra Blanca
  • Cabernet
  • And superstar

3. Short-day 

The third category is the short day. Some of the onion seeds in this category are

  • Granex yellow
  • Red burgundy
  • Red creole
  • Southern bellow
  • Texas super sweet

The best light condition needed for the effective growth of onion seeds that fall under this category is about 10 to 13 hours of sunlight a day.

When To Plant Your Onion Seed

After a series of research, scientists found out that it is more effective and beneficial to start planting your onion seeds 10 to 12 weeks before your last frost date.

The time given before you can start your planting depends on the type of onion seed you’re planting, as different onion seeds require other conditions and time before planting. 

If you wish to sow directly, we advise you to be patient enough until the soil is back to its workable natural area and when the temperature is well above 35°F. 

But during normal climatic conditions, you can equally plant them in your garden as this is the ideal place.

How To Care For Indoor Oil Plants

There are many ways to care for your seedlings to ensure proper growth and development. The crucialrtant area to look into is;

  • Light
  • Water
  • Fertilizer
  • And air circulation 

1. Light

After the sprout of your seedlings, depending on the type, your seeding required likely 12 hours of constant light a day to flourish. 

Light is a constant source of nutrients for the growth of plants, and onion is not exceptional.

2. Water

Nothing grows except it is well watered, so your onion seeds won’t grow in the presence of insufficient water. 

Always water effectively, but when watering, you must be careful to prevent the soil from becoming waterlogged, as this will prevent the plant from growing effectively.

3. Fertilizer

After you’ve planted your seed, the next important thing you need to do is to fertilize the area very well, we recommend you use liquid Kelp Fertilizer which serves as an all-purpose type of fertilizer with no side effects. 

Without the help of fertilizer, 70% of our farm produce may not grow to maturity. Fertilizer is a very important item, you should add it to your list.

4. Air circulation

Air circulation is very important for the proper growth of plants. When planting your seed, remember to space them apart, the reason for this is to allow sufficient air in and between the seed for proper growth and development.
