Best Companion Plants For Spinach

If you have a vegetable garden, you know that spinach is an easy-to-grow vegetable to have around. It’s compatible with most garden vegetables and requires no special care.

In addition, companion planting is healthy for your spinach, allowing a fast growth rate and pest control. So, do you want to know more about the best companion plants for spinach?

Let’s get down to them and take your spinach planting a notch higher. 

The Spinach Plant 

Spinach is native to Persia and a member of the Amaranth family. It’s a hardy leafy green vegetable that is best planted in early spring.

You can also plant it during fall or winter in specific areas. Gardeners love it because of its versatility and rich source of nutrients.

Spinach prefers partial shade in warm climates. Plant them in well-drained loamy soils that are rich in organic content.

In addition, ensure the soil pH is 6.0-6.8. Their ideal growing weather is 10-21 degrees celsius.

Some Reasons For Spinach Companion Planting

As hinted earlier, companion plants come with a plethora of advantages to your spinach. Here is why you want to start spinach companion planting in your garden

Improved Taste 

Spinach tastes better when you plant it with specific plants. What’s more, some plants add minerals to the soil, boosting the spinach’s growth and flavor. 

Reduced Pest And Diseases 

Companions help reduce disease spread. Growing spinach entirely in your garden is a recipe for pest and disease invasion.

On the flip side, companion plants attract (sacrificing themselves) or repel the pest and diseases, saving you from the resultant loss. 

Proper Utilization Of Space

Planting spinach, like any other vegetable, involves separation into rows and columns. Unfortunately, that leaves your garden with lots of unutilized space.

However, planting companion plants will help you use the space available in total. 

Improved Spinach Growth 

Some plants catalyze the healthy growth of spinach by adding helpful nutrients to the soil. Your spinach grows healthier and stronger as a result.

This is best done at the sprouting stage. 

Spinach Saponin

Notably, spinach is also beneficial to its companion plants. This is because it contains the compound Saponin that is produced by its roots.

Other plants produce saponin as well. Saponin has antifungal and antibacterial properties that protect spinach and its companion plants. 

Best Companion Plants For Spinach

It turns out that spinach has a broad range of companion plants. So rather than focusing on individual plants, we prefer giving you a detailed list of these plant groups.

So let’s get down to the list and see what is in store for you. 

1. Leafy Vegetables

Most leafy vegetables can grow well besides spinach. However, not all leafy vegetables are beneficial. Some consume plant nutrients from the soil more rapidly than spinach.

It’s better to grow vegetables that don’t compete with spinach for food. Several leafy green vegetables fit well in this criteria.

Some to consider are 

  • Kale 
  • Lettuce 
  • Swiss chard 
  • Watercress 
  • Beet greens 
  • Cilantro 

You want to use these vegetables as companion plants to your spinach for the benefit of prevention against pests and diseases.

Having them around your garden makes your spinach experience fewer cases of disease spread. The leafy plants will also attract bugs away from the spinach plant. 

2. Brassicas

Brassicas belonging to the mustard family is the other plant group you want to consider growing alongside spinach. The two plants are comfortable growing beside each other since they don’t compete for nutrients.

The plants blend in well because of their ability to absorb nutrients at a slower pace. The brassicas you can grow with your spinach include: 

Radishes 

Radishes stand out amongst brassicas. This is because the plant traps leaf-miners saving your spinach from the effects of the leaf-damaging insects.

Thus, the damage to radishes is only limited to foliage. Besides, radish is a rapid maturing plant, giving a small window of opportunity for damage.

Therefore, leaf miners can only destroy radishes when they are still young. 

Some other brassicas you can add to the list for planting alongside spinach are:

  • Cabbage 
  • Cauliflower 
  • Broccoli 
  • Arugula 
  • Turnips 
  • Bok Choy 
  • Collard Greens 
  • Brussels sprouts 
  • Kohlrabi 
  • Rutabaga 
  • Sweet Alyssum 

3. Alliums

Another group of plants that make good neighbors to spinach is the alliums. Among the numerous benefits they bring, one that stands out is their ability to deter spinach feasting pests.

A typical example is the garlic plant. Garlic repels several insects in the garden, with the common ones being aphids, spider mites, and flea beetles.

Garlic is also known for accumulating sulfur which is responsible for fighting fungal diseases.

Therefore, the sulfur in garlic and the saponin in spinach make an excellent match in preventing diseases in your garden.

Leeks, another member of the allium family, is also known for deterring carrot rust flies from damaging spinach.

Here are other plants of the allium family that make good companion plants for spinach: 

  • Onion 
  • Shallot
  • Chives 

4. Cucurbits

  • Watermelon 
  • Zucchini 
  • Melon 
  • Cucumber

Some peas and beans to plant beside your spinach include: 

  • English peas 
  • Pole beans 
  • Snow Peas 
  • Sugar snap peas
