When are the onions ready to harvest? That's something I asked the first year we grew onions a few years ago. All the books are full of information on how to plant and care for the onions, but nowhere could I find details on when to pick them. Lots of expert gardeners forget how little we know as total beginners and so I promised myself I'd write a post on the topic.
The harvesting will depend on the variety you are growing, the soil in your plot, the amount of sun and shading on the plants and of course the weather. What I'm saying is that you can't say they'll be ready to harvest after a specific number of weeks after planting. It's more a case of watching and observing your vegetable garden, which is all part of the fun. There are some years onions will do well, and then others when they'll seem to have hardly grown since putting the sets in the ground.
Once the little bulbs are set in the soil they will throw up tall green hollow stalk like leaves. Weeds need to be kept at bay. The onion plants will become quite lush and there's nothing quite so fulfilling as a bed full of healthy onions reaching up towards the sky. Keep visiting your onions and cast an eye over them every few days. If you see any flowering stalks shoot up from the odd onion harvest and use those ones immediately, they won't grow anymore and they don't store either. It's always nice to leave one or two, as the flowers are beautiful and the kids are interested in what happens if they're left to grow on.
These onions are drying out under a shelter, they will need turning every day to prevent the green shoots rotting,
or even better, space them out further than this.
After roughly three or four months you'll begin to notice a change in the lush miniature green forest. Some of the leafy stalks will begin to lie down, just a couple at first, but after a day or two most of the crop will be lying down and are ready to harvest. If you are lucky enough to have sunny dry weather leave the crop out in the sunshine a day or two for the leafy tops to shrivel and dry. Otherwise spread them out to indoors or under shelter. If you wish to try your hand at onion ropes leave roughly 10cm of stalk length on each onion for weaving it into a rope. Snip off the short roots. Store in net bags or hang the ropes.
