Why Does Lemon Balm Need Companion Plants?

Lemon balm is actually used as a companion plant for a lot of vegetables and fruit plants, as its aromatic scents are helpful in repelling pests.

But lemon balm plants also need companion plants to grow well and yield productivity.

Below are some reasons why lemon balm needs companion plants:

  1. Increase Nutrients

Nitrogen is an essential substance for a plant’s growth. Companion plants like peas add nitrogen to the soil, which is then taken up by the lemon balm plant, which helps in increased productivity.

  1. Enhanced Flavors

Companion plants with lemon balm may increase the flavor and taste of the plant. Lemon balm, in return, can complement other plants with its fragrance, which might help them as well.

  1. Space Consumption

Lemon balms are known for their rapid growth, and they can take up empty spaces pretty quickly. Companion plants help in the proper and effective usage of garden space.

  1. Shade Regulation

Companion planting around lemon balm also provides partial shade from the scorching heat in summer times. Taller plants often provide shade regulation which prevents smaller plants from heat exhaustion.

  1. Attract Pollinators

Companion plants help lemon plants and the entire garden by attracting insects and pollinators that are beneficial for the plants, which boosts yield.

8 Best Lemon Balm Companion Plants

Companion plants are very beneficial to a plant’s healthy growth and increased productivity.

If you are wondering what companion plants you should plant along lemon balm, you are just at the right place.

We have gathered the best companion plants that will help flourish your lemon balm and your garden. Let us have a look.

1. Melons


Melons and lemon balms are perfect partners when it comes to companion planting. They both complement each other well.

Both are annual plants that require very similar growing requirements, as they both need full sun and well-drained soil for their excellent growth.

Lemon balm helps pollinate by attracting pollinators to the melons and other plants. Growing lemon and melon together helps create a highly productive garden.

2. Beets


Beets form a good relationship with lemon balm. Beets are beneficial to lemon balm as they have deep roots inside the soil, which can go down to 48 inches.

Beets bring water and other nutrients that other plants cannot reach. Beets do not use all the water and nutrients they soak up, so they release them into the upper layers of the soil.

The lemon balm takes up this released water and nutrients, helping them grow and thrive.

3. Tomatoes


Tomatoes make an excellent companion plant with lemon balm. They both help each other in many ways.

Tomatoes help lemon balm with a tall structure to grow up and around it. In return, lemon balm helps tomatoes by attracting pollinators and adding an additional aroma to the tomato plants.

There is a long list of pests that troubles the tomato plant, and this is where lemon balm comes in. It helps in repelling pests and hornworms, which feast on tomatoes.

4. Basil


Basil and Lemon balm grow well together. Basil and lemon balm act as good companion plants due to their pest-repelling abilities.

Basil and Lemon balm can be planted together along the borders of a plant to form a safety ring that helps deter pests. Basil’s lush foliage helps to provide shade for the more delicate lemon balm.

Basil and lemon balm both require the same sun and soil requirements. They also draw pollinators to your garden, making your garden boost yield.

5. Radishes


Radishes make a good companion plant for lemon balm. Radishes have quick growth and don’t have deep roots.

Radishes can be grown between lemon balms and other crops as it maximizes the use of garden space. Planting them near lemon balms also prevents radishes from falling prey to maggots and aphids.

6. Carrots


Carrots are a good neighbor of lemon balm. Carrots have deep roots which go downward, whereas lemon balm’s roots spread outwards.

Carrots soak nutrients from deep down the soil, and excessive water and nutrients are thrown into the soil, which lemon balm absorbs for its benefits.

They do not compete for nutrients; this is why they are good companion plants. Lemon balm can be planted in the same row as carrots which will help as lemon balm repels insects that eat carrots.

7. Cabbage Family
