Introduction

Australia is home to a diverse range of citrus trees that provide an abundance of fresh fruit. However, many gardeners struggle with how to make the most of the space under these trees. Planting the right companion plants under citrus trees can help to maximize garden productivity and increase biodiversity.

Why plant under citrus trees?

Planting under citrus trees provides an opportunity to create a more productive space in your garden. By using the area beneath these trees for companion planting, gardeners can take advantage of the shade and nutrients provided by citrus fruit trees. Companion planting can also help to suppress weeds, reduce soil erosion, and attract beneficial insects that contribute to garden health and productivity.

Best plants to grow under citrus trees

There are a variety of plants that will thrive in the same conditions as citrus trees, including:

Legumes: Plants like clover, peas, and beans are great options for planting underneath citrus trees. They fix nitrogen in the soil, which helps to fertilize the fruit tree.

Comfrey: This plant has deep roots that can access nutrients deep in the soil. It is also high in potassium, which is important for fruit tree productivity.

Herbs: Herbs like mint, chives, and oregano will grow well under citrus trees. They can also help to repel pests and attract beneficial insects.

Berries: Plants like strawberries and raspberries can also thrive under citrus trees. They are low-growing and can help to add some color to the space beneath the tree.

What not to plant under citrus trees

While there are many plants that will thrive under citrus trees, there are a few that should be avoided:

Shade-loving plants: Plants that require large amounts of shade will struggle to grow under citrus trees. Instead, choose plants that can tolerate some amount of sunlight.

Plants with shallow roots: Plants with shallow roots can compete with the citrus tree for nutrients and water. This can stunt the growth of both the companion plants and the fruit tree.

Plants that don't do well in acidic soil: Citrus trees prefer slightly acidic soil, so avoid planting alkaline-loving plants under them.

Conclusion

Planting under citrus trees can be a great way to maximize garden productivity and increase biodiversity. Choosing the right companion plants to grow under citrus trees is key to creating a healthy and beautiful garden space that benefits both the citrus tree and the gardener alike.
