10 Awesome Scallion Companion Plants To Try Out This Year
Scallion plants grow well with plants such as:
1. Beets

When you plant scallions for their sweet roots and leaves, you should consider planting a similar (though different) root vegetable as well. Just like scallions, beets give you sweet roots and leaves. Beets and scallions are compatible plants as they have similar care requirements. You only need to make sure that you properly space the plants.
When you plant onions and beets in the same garden or pot, your onions can get free iron from the beets because beetroots absorb a lot of iron from the soil and can release them back later when they rot.
Well, this companionship is also beneficial to the beets, as scallions can help to repel a few pests.
2. Beans

If you are looking for a plant that will help you reduce how often you fertilize the soil when you grow scallions, you should try beans. As legumes, beans can fix nitrogen into the soil (through the help of a bacterium), and this can benefit both the beans and other plants nearby. You also get even more nitrogen if you allow the bean plants to rot in the soil after decomposing.
When growing beans with scallions, you do not need to worry so much about spacing, as both plants can do just fine when one grows between the rows of another.
However, you should ensure that the leaves of both plants have access to sunlight, as they are both sun-loving plants.
3. Cabbage

Here’s an awesome green onion companion that you can grow in your garden. Cabbage will benefit a lot from the relationship because scallions help to repel some insect pests that attack cabbages. Scallions will also benefit, as cabbages only grow in nutrient-rich soil, so you ensure both of them get strong and full of nutrients.
Note that your cabbages should be 24 inches apart if you want to grow scallions between them. Remember that cabbages need crop rotation so that they do not get a lot of pests and diseases in their next growing season.
This means that you cannot grow cabbages and scallions continuously for years in the same spot.
4. Summer Savory

Here’s a good companion plant to help your scallions grow free from pests. Savories are herbs that can repel insects and other pests that attack scallions. You only need to plant scallions close to or between the summer savories. When it’s time to harvest, you will get both roots and herbs to cook the sweetest meal.
Note that both plants love sunlight, so the leaves of your savories should not cover the leaves of your scallions. You should properly space the savories if you want to grow the scallions between them.
5. Peas

Just like beans, peas also add nitrogen to the soil, as they are legumes. Leguminous plants can help you to grow your scallions without adding much nitrogen. However, peas require the addition of potassium, phosphorus and other nutrients if they are not available in the soil.
To help your scallions benefit a lot from their pea companions, plant the peas at least two weeks before the scallions so that the soil contains slightly more nitrogen before the scallions enter their vegetative phase.
Well, if you have planted peas in the garden before, you can plant the scallions right away, as nitrogen must have been released from the previous peas.
6. Carrots

Scallions are bulbous plants, so here’s a tuberous plant for you. Both scallions and carrots can grow just fine together. However, ensure that you space them properly (at least 12 inches apart while planting), as they need a lot of space for their roots while growing. Also, ensure that their leaves are getting enough light from the sun.
Both scallion plants and carrots will benefit from each other. While the carrots can enrich the flavor of the scallions, the scallions will grow just fine, as carrot roots will not disturb theirs while growing.
7. Clover

Do you want to grow your scallions without adding extra nitrogen to the soil? Here’s an awesome type of legume for you. Clover, which can grow as a weed, helps to improve soil nutrients, as it is very effective in attracting nitrogen-fixing bacteria. These plants have even more uses for your scallions.
If your scallions are disturbed by little insect pests such as aphids, clovers can attract predators such as praying mantises and ladybugs to prey on the scallion pests. This means that your scallions will get more nutrients as well as develop free from pests when you grow them with clovers.
8. Strawberry

Strawberry is indeed a plant that you’d surely want to grow in your garden. As a companion to scallions, a strawberry plant may not necessarily add value to the relationship directly. However, both plants can grow just fine together, and in the end, you will harvest sweet strawberries and scallions.
One indirect way that your scallions can gain from this relationship is when you care for the strawberries. Strawberries are fragile plants that need raised beds, a lot of care and mulch, so your scallions will benefit from the added nutrients, ideal growing conditions and extra mulch that you provide for the strawberries.
9. Tomato

Just like strawberries, tomatoes are fragile plants that need a lot of care. This means that green onions will benefit a lot when you grow them with tomatoes, as you’d extend the care for the tomatoes to the scallions. However, note that this companionship has a slight disadvantage.
Tomatoes attract a lot of pests both in their vegetative and fruiting phases. Tomatoes attract cutworms, onion nematodes and other soil-borne pests, so your scallions (with roots growing underground) can be affected if you do not regularly deter pests from the garden. So long as you have good pest control techniques, you are good to go.
10. Peppers

Scallion companion planting is truly rewarding when you choose the right types. One good rule to know the right companion for your scallions is that any plant that isn’t harmful to the scallions is a good companion. Peppers are plants that you benefit from, as they give you spicy fruits to make your food more delicious. If you have a scallion garden, you can always add peppers.
Pepper plants may grow bushy, but they do not block sunlight from reaching the scallions. Also, pepper roots do not disturb scallion roots or compete with them so long as there are nutrients in the soil.
Conclusion
Planting scallions will be easier for you now, as you know plants that can simplify your scallion growing journey.
