How To Harvest And Store Onions

Onion growing has become almost a holiday event. Every year we plant our sets right before Christmas. The harvesting always begins at Easter time.  

Although we do start some earlier in fall from seeds we've saved, it sometimes fails. It happens with weird weather these days mostly. 

The one thing I know, is onions grown organically in the garden...well...there is nothing like them!! Firm and delicious and keeping a basket full in the kitchen is mandatory around here.

 The signs of harvesting time is when you begin to notice most of the onion tops falling over. They have a nice bent place an inch or so right above the bulb. If it is your first time to grow onions don't think they are dying on you. They are simply ready to pull. 

We begin by gently pulling them up, preferably on a dry day and laying them down on the ground. Once we've pulled them up it is time to go back and gather them. We carry them by bunches and lay them gently up in nice neat rows on the drying racks. I like to keep them sorted by variety and colors. We grow short day varieties, but some mid day as well. I tell you why in a minute.

We may do things a bit different than some folks, but we've had pretty good success with our methods. In the top photo you can see our drying racks. My husband, better known as Mr. Garden to most, built the racks strategically at the southern part of the gardens. 

We get a wonderful breeze of warm dry air almost constantly during harvesting time. The racks have a roof made of tin to help protect from rain and chicken wire shelving to allow good air flow. 

The whole thing is nestled under some nice shade trees to help protect the onions from the sun. The best way to dry your onions is simply, fresh dry air and shade. 

After about a week on the drying racks the skins will have begun to dry and protect the juicy onion bulb inside. This is why we must pull them gently and lay them up to dry gently as well. The less damage done during harvesting the nicer the skins will be.

It's at this time I can start going through the harvest and gently brushing dirt off. I usually use a large soft bristled brush and then lay them back down on the racks. You will be able to cull out any undesirable onions at this time as well. Sometimes you will find a few that had tried to go to seed and the bulb will feel hard like a piece of wood. You may also find some that are a bit mushy. Throw them out into the compost pile.

After about a good long month the long grassy stems of the onions will have become good and dry as well. It is also at this time that the weather here in Texas begins to turn hotter and more humid. That is the sign that they need to come indoors for storage. 

Back to the short day and mid day variety question for just a minute. It is recommended that we grow short day in our growing zone. Mid days will grow here, but take a few more weeks before they are ready to harvest. The reason we grow both types is because mid day varieties are well know to store and keep longer that the short day onions. This is why I like to keep my varieties sorted out when putting them up on the drying racks. 

The key to storing onions is cool and dry! That can be hard here in Texas so they must be brought indoors.  They can be kept in baskets after cutting the stems off. Burlap sacks work great as well as saved netted bags from purchases made at the farmers market. 

We like to braid many of our onions in nice clumps to hang indoors. After we braid we hang them in the potting shed where is is fairly cool and breezy in the shade. But even at that there is no holding back the heat and humidity. So with a nice looped string at the top of the braid we bring them indoors to a room on the northern side of the house where I keep a nice slow ceiling fan blowing. 

I try to make sure I make use of the white onions and the short day varieties first. The white onions always seem to want to go bad first. Then the yellows and the reds and Bermuda stay best longest.

Happy Gardening!

    1. Hi Diane! Loved seeing your new babies online today!!! Totally adorable !! xxoo

  3. Can you tell me the best way to keep them from going to seed? I have bent the stops, but most of the time they break. Maybe a silly question, but does the rain get into the onion from this breakage? Love your set up!!

    1. Most of the time rouge onions wanting to go to seed is caused from the onions planted to deep.For me the best thing to do is go ahead and harvest that onion wanting to seed, chop it up and eat it. Hope this helps Trish. xxoo
