How to Grow Onions

Because onions are used in almost any dish and can store well, growing it in your own backyard can be a practical enterprise.  What novelty it is to pick onions in the garden instead of at the green grocers!

Onions are very resilient and can grow in almost any climate – they are even frost-resistant.

They can be grown from seeds and planted from sets or partly-grown onions bulbs.  But whichever you choose, it is important that you prepare the soil before planting.

You can add compost to the soil a week or so before sowing or planting.  Tread on the soil in order to make it a little firmer.  Onions will thrive in sandy loams to heavy clay but make sure that the soil is moist before planting.

Onions prefer a soil that is slightly acidic – those with a pH between 5.5 to 6.5.

If you choose to sow seeds, sow them approximately two centimeters deep into the soil.  A gap of at least one inch should be maintained between each seed.  If you are planning to sow in rows, there should be a space of 30 centimeters between each row.

If you plan to use onion sets, it’s best to plant them in late March.  If you have a polytunnel, you can plant the sets earlier.  Dig a hole for each onion set and cover it with soil, the tip of the neck must show through the soil surface.

The space between rows must be at least 30 centimeters, with the sets 10 centimeters apart.  Unlike sowing from seeds, onions planted through sets do not require thinning as they grow.

It is important to weed frequently as your onions grow.  If you have sown from seeds, thin the onions to a space of 10 centimeters apart when they reach a height of five centimeters.

You may not be able to see how big the bulbs are because they grow underground, but you can harvest your onions when the shoots reach a height of about 30 to 40 centimeters.
