Companion Planting for Lemon Trees: Tips and Tricks


If you have a lemon tree in your garden, you know how rewarding it is to harvest fresh lemons for cooking, cleaning, or making lemonade. However, growing lemon trees can be challenging, especially if you want to avoid using chemicals or pesticides. One way to enhance your lemon tree’s health and productivity is through companion planting. In this article, we’ll explore the best companion plants for lemon trees and how they can benefit your garden.

What is Companion Planting?

Companion planting is the practice of planting different crops together to create a mutually beneficial environment. Companion plants can improve soil quality, attract beneficial insects, repel pests, and provide shade or support. By planting certain plants next to each other, you can enhance their growth, flavor, and yield.

Benefits of Companion Planting for Lemon Trees

Companion planting can offer several advantages for lemon trees, including:

  • Improving soil quality: Some companion plants can fix nitrogen, add organic matter, or enhance soil structure, which can benefit lemon trees’ root development and nutrient uptake.
  • Deterring pests: Certain plants can repel or confuse pests that might attack lemon trees, such as aphids, scale insects, or spider mites.
  • Attracting pollinators: Lemon trees need bees or other pollinators to produce fruit. Companion plants that bloom early or late in the season can attract pollinators and increase fruit set.
  • Providing shade or support: Some companion plants can act as living mulch, groundcover, or trellis for lemon trees, reducing water loss, preventing erosion, or protecting from wind or sun damage.
  • Enhancing flavor: Some herbs or vegetables can complement the flavor of lemons and create a more diverse and flavorful garden.

Now that you know why companion planting is beneficial, let’s look at some specific plants that can grow well with lemon trees. Keep in mind that not all plants may work in your climate, soil type, or garden layout, so experiment and observe what works best for you.

What plants should not be planted near lemon trees?

Some plants should not be planted near lemon trees because they might compete for nutrients, attract pests, or inhibit growth. Avoid planting the following plants near your lemon tree:

  • Avocado
  • Cherry
  • Fig
  • Pomegranate
  • Walnut

How far apart should lemon trees be planted?

Lemon trees should be planted at least 10 feet apart to allow for proper air circulation, sunlight exposure, and root development. If you’re planting multiple trees, space them at least 20 feet apart to avoid crowding and competition.

Can I plant companion plants in the same hole as a lemon tree?

No, you should not plant companion plants in the same hole as a lemon tree because they might compete for space, nutrients, and water. Instead, plant companion plants around the lemon tree, leaving at least 2-3 feet of space between them.


Companion planting can be a fun and effective way to improve your lemon tree’s health and productivity. By choosing the right companion plants, you can create a diverse and thriving garden that benefits both your taste buds and the environment. Remember to observe your plants’ needs, experiment with different combinations, and enjoy the fruits of your labor.
