How to Grow Onions in Elgin, Texas, United States of America

No one is really sure where onions were first cultivated. The onion is believed to have originated in Asia, though evidence shows that onions may have been growing on every continent. There is evidence of onions growing in Chinese and Indian gardens as early as 5000 years ago. Organized cultivation of onion estimated to have begun around 3,500 BC, and its usage is clearly seen in ancient Egyptian culture religious ceremonies as painted on tombs and pyramids. One thing is certain, the onion has been in use for over 5000 years. Yikes that’s a lot. Onions belong to the genus Allium, which also includes leeks, garlic, shallots and chives. All onions grow under the ground and have green/bluish tubes that grow above ground. They are very easy to grow and can grow in just about any type of soil so long as they get sun and water.

Onion Germination Guide

(Stage 1: Germination)

Germination is the process by which a plant grows from a seed. It is the first stage of the plant growing process and it begins when the seed is sown and ends when the radicale emerges out of the seed.

All seeds require proper soil temperature, moisture, air and light conditions to germinate successfully. However, during the germination stage the seeds require more soil warmth and moisture than light exposure.

Seeds respire just like any other living organism, requiring oxygen and producing carbon dioxide (CO2), so it is crucial to use a soil media that is sufficiently aerated so that the seeds do not “suffocate”.

100% of our growing experts recommend to directly sow onion seeds into the ground. What is direct sowing and why do I care about it?

Onion Growing Guide

(Stages 2-5: Growth)

Once seed has germinated and radicale has emerged the second stage of the plant growing process begins, developing from radicale to cotyledon -the embryonic first leaves of the seed forming a young seedling.

During the third stage of plant development cotyledon develops to 3-4 true leaves, stem begins to grow, becoming a mature seedling.

In the fourth stage the mature seedling develops to a young plant, ready for transplanting.

The fifth stage of plant development the plant is fully mature bearing fruit and/or flower.

The following guidelines apply to all of the onion plants’ needs during stages 2-5 from radicale emergence to full maturity. During these stages sunlight becomes a more active participant in plant growth and development than in the germination phase.

Soil pH is an important factor during these stages as well. What is pH and why is it important?

How difficult is it to grow onions?

Growing onions, or any other vegetable for that matter, is not hard, however some plants require more attention and care than others depending on the following factors:

 

Are you starting to grow your plant from seed? seedling? young plant? Depending on what stage plant you choose to plant will impact growing difficulty and patience.

The length of the growing season for your exact garden location.

Whether you direct sow in the garden or start in trays and then transplant also affects the level of difficulty

Growing difficulty level - 0

Growing patience level - 0
