How to Plant Basil and Tomatoes: The Perfect Distance for Optimal Growth



Are you wondering about how close to plant basil and tomatoes? If so, you are not alone. This is a common question that many gardeners have asked themselves at some point. The truth is, planting these two popular crops together can be a real game-changer for your garden. However, there are certain factors to consider when deciding on the distance between them.

Basil and tomatoes both belong to the same family of plants – Solanaceae. They share an affinity for warm weather and lots of sunshine. Additionally, basil has been known to improve the flavor of tomatoes when planted nearby due to its aromatic oils that help repel unwanted pests. But just how close should these two be planted? In this article, we will explore everything you need to know about pairing up basil with your tomato plants in terms of spacing requirements and other considerations.

How Close to Plant Basil and Tomatoes: Tips for an Optimal Harvest

If you are a gardening enthusiast, then you must know the benefits of planting basil and tomatoes. These two plants complement each other both in terms of flavor and growth requirements. But how close should they be planted together? In this article, we will discuss everything you need to know about planting basil and tomatoes together.

Before we dive into the specifics, let's talk about why these two plants make great companions. Basil is known for its strong fragrance that repels pests such as mosquitoes, flies, and spider mites. It also attracts beneficial insects like bees that help pollinate tomato flowers resulting in better fruit production. On the other hand, tomatoes produce solanine which inhibits the growth of some pests like aphids while providing shade to basil which needs partial sunlight.

Benefits of Planting Basil with Tomatoes

Planting basil with tomatoes has several benefits including:

  • Pest control: As mentioned earlier, basils strong scent helps keep away unwanted pests while attracting beneficial insects.
  • Improved flavor: The aroma from fresh basil leaves enhances the taste of ripe tomato fruits making them even more delicious.
  • Increased yields: Herbs like basil also help retain moisture around your crops' roots leading to better yields.

Now that we understand why it's essential to plant these two crops together let's look at how best they can be planted in a garden bed or container garden.

How Close Should You Plant Them?

The distance between plants depends on several factors such as soil type or variety being grown hence there is no one-size-fits-all approach when planting vegetables & herbs side by side.

Typically most farmers prefer spacing their mature tomato bushes 24 inches apart from each other while leaving 12 inches between rows – this allows air circulation thus preventing fungal diseases common among nightshades family members i.e., eggplants & peppers; however adding sweet smelling herbs like basil to this mix might reduce the space requirements as they help repel pests and provide natural shade.

A good rule of thumb when planting tomatoes and basil together is to plant them at least 10-12 inches apart. This distance is enough to allow each plant's roots enough space while also maintaining adequate airflow in between. When planting in containers, it's recommended that you use a 5-gallon pot for each tomato plant with one or two basil plants around its perimeter.

Tips for Planting Basil with Tomatoes

Here are some tips that can come in handy if you are planning on planting these two crops together:

  1. Start by preparing your soil: Ensure that the soil is well-drained, fertile & moist before planting either crops.
  2. Choose compatible varieties: Select tomato varieties early; determinate types require less spacing while indeterminate ones need more room as they tend to grow taller and wider.
  3. Plant seedlings diagonally: Instead of directly aligning your seedlings next to each other try staggering them diagonally – this allows better sunlight exposure leading healthier growth habits over time.
  4. Prune regularly: Regularly prune both tomatoes & basils' foliage weekly – this ensures proper airflow hence reducing chances of fungal infections & diseases which might result from poor circulation patterns i.e., blight common among nightshade members especially when overcrowded.


Planting tomatoes with basil has been a tried-and-tested technique used by vegetable gardeners worldwide for centuries now due too their complementary properties – doing so provides numerous benefits ranging from pest control all the way up increased yields! Remember always choose compatible tomato/basil varieties ensuring adequate air flow through out crop growth cycle ultimately leading optimal harvests year after year!


What is the ideal distance between basil and tomatoes when planting them together?

Basil and tomatoes are classic companions that grow well together. However, it is essential to provide enough space for both plants to flourish properly. When planting basil and tomatoes in the same bed, make sure they are at least 12 inches apart from each other. This distance allows ample room for both plants' roots to develop without competing with one another.

It's crucial also to consider the varieties of basil being used since different types of basils require various spacing distances. For instance, bush-type basils like Greek Basil or Spicy Globe Basil need less space than large-leafed ones such as Genovese Basil or Thai Holy Basil.

If you're growing indeterminate tomato varieties like Brandywine or San Marzano, give them more space—upwards of 24 inches—for abundant growth and fruit production.

Can I plant basil directly next to my tomato plant?

While it's okay in some situations for these two plants—basil and tomato—to be grown side-by-side; however, planting them too close can lead to problems down the line.

When planted too closely together without adequate air circulation through foliage can cause humidity buildup that creates a wet environment where fungal diseases thrive. Both species attract pests such as aphids that may infect your crop if left untreated.

Therefore, it's recommended always keeping a minimum distance between these two companion plants while making sure there is plenty of airflow by thinning out branches if necessary.

Why should I grow basil with my tomatoes?

Growing basil alongside your tomato garden offers numerous benefits beyond just flavor pairing:

  1. Natural pest control: The strong aroma emitted from fresh herbs keeps away unwanted insects like aphids.
  2. Improved pollination: Bees love visiting flowers on both plants which increases pollination rates resulting in bigger harvests.
  3. Better health: Some studies show eating fresh herbs regularly boosts overall health, including reducing inflammation and preventing chronic diseases.

Are there any other plants that benefit from sharing space with basil and tomatoes?

Yes! There are many garden vegetables that can benefit from growing together with basil and tomatoes. Some of these include peppers, eggplants, zucchini, cucumbers, and beans.

When grown in the same bed as tomatoes/basil or nearby in containers or raised beds ensures ample cross-pollination between plants for improved yields. Additionally adding diversity to your vegetable plot helps repel pests by creating a more varied ecosystem within your garden soil.

How much sun do basil and tomato plants need?

Both tomato plants and basil require full sun exposure- which means at least six hours of direct sunlight per day to grow optimally. However planting them too close together may shade one plant excessively leading to developmental problems like slow growth or poor fruiting compared to when receiving adequate sunlight.

If you're planting them outside where they will be exposed entirely throughout the day ensure they are spaced appropriately allowing each plant enough room while still being near enough not to disrupt their companion relationship. If you're growing indoors under artificial lights providing 12-16 hours of light every day is ideal for both species' optimal growth rates.
