Arugula, also known as rocket or roquette, has become increasingly popular in recent years due to its mild flavor and versatility. Not only can arugula be enjoyed raw in salads and sandwiches, but it is a great addition when sautéed or grilled. If you’re looking to create your own outdoor garden this summer but are unsure of what would pair best with your arugula crop, then you have certainly come to the right place! In this blog post we’ll explore the many companion plants that will complement an arugula garden – from garlic and onions to nasturtiums and marigolds. We’ll go into detail on which plants work well together so that you can craft a beautiful array of flavors for your meals!
What Is Companion Planting?
Companion planting is a time-honored technique that involves strategically planting different species together to enhance their mutual growth and benefits. It can involve planting flowers, vegetables and herbs close together or in alternating rows for maximum benefit. Companion planting is especially beneficial for arugula, as it helps foster healthy growth and protect against pests and diseases. Enhance the flavor of your arugula, repel garden pests, and attract beneficial insects by strategically planting compatible companions nearby. Your garden will flourish with this simple yet effective technique.
When choosing companion plants for arugula, look for ones that require similar soil conditions, light exposure and water needs. Consider pairing your arugula with other leafy greens such as kale or spinach. Aromatic herbs like parsley, thyme or oregano also make great companions. Other vegetables like tomatoes, carrots or radishes do well when planted near arugula. Flowering plants, such as nasturtiums or marigolds, can help deter pests and attract pollinators to your garden.
What Are The Benefits?
The benefits of planting companion plants alongside arugula are numerous. Not only do the companions bring color, texture and scent to your garden, they also help ward off pests and provide nutrients that can increase the health and yield of your arugula crop. Companion plants can attract beneficial insects such as bees and ladybugs which will naturally control pest populations in your garden. Additionally, certain plants have root systems that can help fix nitrogen or other essential minerals into the soil. This prevents nutrients from leaching away and allows other nearby plants to benefit from this increased nutrient availability. Finally, companion planting is a great way to reduce weeds by filling in open spaces in the garden where weed seeds could otherwise germinate.
All of these factors make for healthier, more productive gardens and plenty of delicious arugula!
