Growing onions is a popular task for millions of gardeners and knowing when to harvest red onions – along with yellow and white varieties – is important for success. If you harvest onions too early, it means a limited storage life. But, harvesting too late could mean a split or rotten bulb. In this article, I’m going to review two perfect times for harvesting red onions. One is ideal for fresh use and the other is best for optimizing storage life.
Why knowing when to harvest red onions mattersLike their cousins chives, leeks, shallots, and garlic, red onions are a member of the onion family (Amaryllidaceae). Planting immature red onion bulbs (known as sets), seeds, or seedlings in the early spring is a rite of passage in the garden. For many, it signals the start of the growing season since onions can be planted even as the last snow of the season falls (called an “onion snow” by my Pennsylvania Dutch ancestors).
Though there are many different types of onions, for many growers, red onions are a favorite, myself included. I enjoy their tangy flavor and the color they add to dishes. In this article, I’m going to focus on when to harvest red onion varieties, though this information is appropriate for other varieties, too.
Planting tipsBefore we get to the harvest, it’s important to share quick rundown of the planting and growing process. As mentioned, red onion plants are grown from either onion sets (second year bulbs), red onion seeds, or red onion transplants (young, first year plants). I offer extensive information about growing onions from seed and why it is beneficial in this separate article. That being said, growing red onions from sets or transplants is fine, too. I often do a combination of both.

There are areas in our homes that tend to be common storage areas, such as attics or basements. But just because a space can hold a stack of boxes doesn't mean it should. Before you stash a box of clothes or holiday decorations away, consider the ways in which factors like temperature, moisture, and household pests might affect the items you're storing.
As we enter fall and the pumpkin spice latte returns, it only makes sense to gain inspiration from the beloved seasonal drink to decorate our homes.

Not everyone has a backyard appropriate for a large garden, but almost everyone can keep a container plant. Size is only one of the many advantages of growing plants in containers rather than in the ground. This only works well, however, if you select plants that are happy living in a pot. Gardeners in the West have many choices. Read on for some top options for California or Nevada container gardening.

How does a kitchen gardener choose what to grow? It’s about balancing quite a complex set of variables, which include the space and time available, the local climate and soil, the gardener’s skill level and what they like to eat. That last one is, itself, quite a complicated topic as culture plays a significant role. There are many thousands of edible plants on the planet; most people only eat a small number and grow fewer still.
A little while ago, I told you about a preliminary experiment that Dr Wieger Wamelink and his team at the University of Wageningen conducted. It demonstrated that it is possible to grow plants in simulated Mars and Moon soils.
In this NASA image from January 2020, you can see Lashelle Spencer taking measurements on ‘Red Robin’ dwarf tomato plants. Lashelle is a plant scientist at NASA’s Kennedy Space Center in Florida, and this photo was taken inside the Plant Processing Area in the spaceport’s Space Station Processing Facility.
We’re not the biggest fans of cabbage and kale, and we don’t have a large garden, so I don’t generally bother with winter brassicas. They’re large plants, and they take up space for a long time. I do make an exception for purple sprouting broccoli, which is basically Food of the Gods. It’s one of my favourite things, and I would be disappointed if we didn’t have it. In fact, I try and squeeze in too many plants, and then worry that there won’t be enough.
