More about our red winter onion

Winter onions are fairly large onions that can withstand low temperatures. Contrary to their name, they only start growing well after winter. However, if the plants develop a good root system before winter, you can harvest them considerably earlier than the onions you plant in spring.

These red winter onions are perfect for the empty spaces that become available in autumn.
  • Variety name: Red Arrow
  • Family: root
  • Number of plants per space: 16 (or 9 large*)
  • Height: 40 to 50 cm
  • Planting time: mid-September to mid-November
  • Sowing depth: 2.5 - 4 cm
  • Harvest time: from the end of May
  • Germinates between 5 and 21°C in 10 to 14 days
  • Preferably in full sun
Note: the onions are fresh and cannot be stored for long. Therefore, we only sell them temporarily and while supplies last.

Sometimes there are quite a few large onions in a net, so there are fewer than 32 pieces. Because they will probably become a bit larger, it's better to plant 9 in a patch - instead of 16.

Wat is er bijzonder aan Rode Winteruien?

Red onions are generally sweeter and crunchier than yellow onions. With their milder flavor, they are perfect for cold dishes. Although you can also use them for warm dishes. 

In addition, red onions look a bit more special than the ordinary yellow ones. 

Because you plant these winter onions in the autumn, they are ideal for beds that become empty at that time. Onions prefer loose and airy soil and natural fertilizers. They also do very well in MM-mix.

Planting Winter Onions

Winter onions should be planted between mid-September and mid-November. It is best to plant them as soon as you receive them, as they do not stay fresh for long.

Growing winter onions is super simple. You can find the instructions for this in our app as well. In short, here's what you need to do:
  1. Choose a spot in full sun, or use a MM-mini and place it in a sunny location.
  2. You can fit 16 onions in one spot.* So, make 16 holes that are 2.5 to 4 cm deep and place the onions in them. Then, give them some water.
  3. During the winter, the plants will hardly grow, so you don't need to do anything. However, provide them with some protection against harsh weather and severe frost. For example, you can use a MM-hat.
  4. Fertilize only in early spring. Around that time, the days become longer, the temperature rises again, and the foliage starts to grow well.
    Harvest when the foliage is completely yellow and starts to fall over: between the end of May and mid-July. Then the diameter of the onions is approximately 5-7 cm.

    *Note: sometimes there are quite a few large onions in a net, so there are fewer than 32 pieces. Because they will probably become a bit larger, it's better to plant 9 in a patch - instead of 16.

What do you use red winter onions for?

You can fry, bake or stew the onions, fry them, prepare them in the oven, make soup from them and even use them raw in salads.

Red onions are especially nice for the latter: raw in salads or in thin slices on a healthy sandwich.

I also really like red onions in dishes where you briefly sauté them, or in stir-fry dishes.
