How to Plant Onion Seeds

Most amateur gardeners avoid starting their onions with seeds.  They do take a little more skills compared with planting sets or transplants.  However, they are not all that hard to do.

First, determine the area where you would like to grow the onions.  Choose a site that gets plenty of sunlight, with a soil that has good drainage and has not been previously planted with onions or any of the onion family.

Ideally, it’s best to sow onion seeds in springtime.  Make sure the soil is not soggy with acidity between 6 to 7.5 pH.  Add well-rotted manure or compost to the soil, rake and firm up the soil.  Let it sit for a couple of weeks before planting.

Once your soil is ready (moist , not muddy), with no stones or weeds around the area, it’s now time to plant.

Dig drills or shallow holes on the ground that is about half an inch deep and six inches in diameter.  There should be a gap of approximately nine inches in between rows.

Scatter seeds in groups of three up to about five per drill.  Cover the seeds back with soil and pat down to make it firm again. Water the soil.

It’s important never to allow the soil to go dry for proper germination to occur.  After three weeks, you should see the beginnings of foliage sprouting from the ground.  Once this happens, they should be thinned out an inch up to two u=inches apart.  This should be enough space for the bulbs when it begins to expand.

After a few more weeks, you can thin the onions again to one onion plant every four inches.  Make sure to keep the soil weed-free.  Watch out for birds which might pull your crops from the ground once your back is turned.

Mature onions can be harvested one week after their tops have started to fall.  The greens can be harvested when they reach a height of at least six inches.
