Taking care of basil plants in pots can be an enjoyable and rewarding experience. Growing basil in pots is not only a practical way to have fresh herbs at your fingertips, but it also allows you to enjoy this fragrant and versatile herb even if you don’t have outdoor gardening space. With the right pot, soil, and proper care, you’ll be able to maintain a healthy basil plant that adds a burst of flavor to your favorite dishes.

Choosing the right type of basil, selecting an appropriate container, and proper planting techniques are all crucial factors in creating a thriving environment for your potted basil plant. Understanding the specific needs of basil will also help you to provide the right balance of sunlight, soil nutrients, and watering, ensuring that your plant flourishes.

Key Takeaways

  • Selecting a suitable pot and the right variety of basil is vital for successful growth.
  • Proper sunlight, watering, and fertilization support the overall health of your potted basil plant.
  • Ongoing care and maintenance, including harvesting and companion planting, will maximize basil’s usefulness and flavor.

Selecting the Right Pot

When growing basil in a pot, it’s important to choose the right container for your plant’s needs. Let’s go over two crucial elements to consider: Size and Material, and Drainage.

Size and Material

The best pot size for most basil plants is 9 to 15 inches deep and 12 to 18 inches wide1. Ensure the pot has a minimum soil volume of 3 gallons per plant1. Basil grows best in large, deep pots, giving the plant’s roots ample space.

There are various pot materials available, such as plastic, clay, ceramic, or even fabric pots. While each option has its pros and cons, the most crucial factor is that your chosen pot should have enough space for your basil to grow. When selecting a material, consider other factors like weight and durability. For instance, plastic pots are lightweight, while ceramic pots can be heavy but retain moisture2.


Regardless of the chosen container – be it a pot, laundry basket, or even a kiddie pool – it’s essential to have proper drainage3. Basil enjoys moist soil, but it doesn’t like sitting in water, so ensure the container has drainage holes3. This prevents soil from becoming waterlogged and protects your basil from potential root rot3.

If you’re using makeshift containers like a kiddie pool or a laundry basket, you may need to add drainage holes yourself. Just use caution when drilling or cutting these holes to avoid damaging the container or yourself.

In summary, selecting the right pot for your basil involves considering the pot size, material, and ensuring proper drainage. A well-chosen container will provide the ideal environment for your basil to grow and flourish.

Choosing Basil Varieties

Common Varieties

When it comes to growing basil in pots, there are many options to choose from. Some of the more common varieties include sweet basil, purple basil, lemon basil, and Thai basil. However, you can also grow rarer types like cinnamon basil, dark opal basil, holy basil, and lime basil in containers.

Sweet basil is a popular choice for its rounded, medium green leaves and its intense scent. It’s often used in a wide variety of dishes and can even repel mosquitoes.

Purple basil offers a slightly different flavor profile, with its dark purple leaves making an attractive addition to any garden. For those who enjoy experimenting with unique tastes, varieties like lemon basil and lime basil have a citrusy kick, while cinnamon basil has a warm, spicy flavor.

Flavor Profiles

Diverse in both appearance and taste, basil can easily turn any dish into a culinary delight. Let’s take a look at some popular basil varieties and their flavor profiles:

  • Traditional Genovese basil is prized for its sweet taste with a hint of mint. It’s popular for Italian dishes like pesto and Caprese salad.
  • Thai sweet basil has a strong licorice-anise flavor, often found in Thai curries and stir-fries.
  • Curly basil provides a fun, different look with its frilly leaves, but it’s also tasty and widely used in various dishes.
  • Holy basil has a strong, peppery taste, often used in Indian and Thai cooking.
  • Bush basil has tiny leaves but packs a flavorful punch in salads or as a garnish.

Remember, there’s no need to limit yourself to one variety. Growing multiple types of basil in pots allows you to enjoy a burst of flavors in your cooking, all from your very own garden.

Planting Basil

When it comes to planting basil in pots, there are two methods you can choose from: starting from seeds or transplanting an already established plant. This ultimate guide will walk you through both methods and help you pick the best time to plant your basil.

Starting from Seeds

Starting basil from seeds is an easy and cost-effective way to grow this popular herb. To begin, you’ll need to prepare a moist soil mix in a container with drainage holes. Sow the basil seeds about 1/4 inch deep and lightly cover with soil. Make sure to place the container in a warm, sunny location and keep the soil consistently damp.

Basil seeds typically take 5-10 days to germinate. Once the seedlings have two sets of true leaves, you can thin them out to leave about 12-18 inches between each plant. This helps ensure healthy growth and prevents overcrowding.


If you’re planning to transplant a basil plant, make sure to choose a healthy, vigorous plant from a nursery or garden center. Transplanting is best done in the evenings or on a cool, cloudy day. This avoids stressing the plant in direct sunlight.

Carefully remove the plant from its original container, ensuring not to damage the roots. Place your basil plant into the new pot, filled with a quality potting mix, at the same depth it was previously growing. Water it thoroughly to help it settle in its new home.

Best Time to Plant

Basil is a sun-loving herb, so it thrives in warm temperatures. The best time to plant depends on your region’s climate, but a general rule of thumb is to wait until all danger of frost has passed. Basil can be sensitive to cold temperatures and will not grow well if exposed to frost.

Providing afternoon shade can be beneficial, especially in hotter climates, to prevent the plant from wilting in extreme midday heat. Monitoring the soil moisture and temperature will keep your basil plants happy and healthy.

Potting Soil and Compost

Soil pH

Basil plants thrive in fertile, well-drained soil with a pH between 6.0 and 7.0. It’s essential to test your potting soil’s pH to ensure it falls within this range for optimal growth. You can purchase a pH testing kit from a garden center or online store to measure the soil’s acidity or alkalinity.

If your potting soil has a pH outside the ideal range, you can adjust it. For example, if the soil is too acidic (pH below 6.0), add a little lime to raise the pH. On the other hand, if it’s too alkaline (pH above 7.0), you can lower the pH by mixing in some peat moss.

Nutrient Content

Basil requires sufficient nutrients to grow healthy and strong. Two essential components needed for nutrient-rich soil are potting mix and compost or organic fertilizer.

  • Potting mix: Choose a high-quality potting mix that provides a balance of nutrients, moisture retention, and drainage. It’s essential to maintain adequate moisture levels, as basil prefers moist soil. However, avoid waterlogged conditions, as this can lead to root rot.
  • Compost: Incorporating a few inches of compost or other rich organic matter into your potting mix is a great way to nourish your basil plants. Compost provides essential nutrients, improves soil structure, and enhances water retention. Additionally, using compost reduces the need for synthetic fertilizers, making it a more sustainable option.
  • Organic fertilizer: If you prefer not to use compost, you can opt for an organic fertilizer as an alternative. Look for a slow-release formula that provides an even distribution of nutrients over time. Be sure to follow the manufacturer’s instructions for application rates and intervals.

By ensuring that your basil plants have the right soil pH and nutrient content, you’ll be well on your way to cultivating healthy, thriving plants in your pots. Remember to always monitor soil moisture and adjust your care routine as needed for the best results.

Sunlight and Placement Requirements

Outdoor Placement

Basil plants thrive in full sun, ideally receiving six to eight hours of direct sunlight each day. If you live in a hot climate, it’s a good idea to offer your basil some afternoon shade for relief, as too much sun can cause leaf burn. When placing your basil pots outdoors, look for a sunny spot that provides the right balance of sunlight and shade.

Indoor Placement

For those growing basil indoors, choose a sunny windowsill that gets plenty of sunlight each day. Basil plants need ample light to grow well, even when placed indoors. A south-facing window is often an ideal location to ensure your basil receives the necessary warmth and sunlight.

Keep in mind that basil is a warm-weather herb and will not tolerate cold temperatures. If you notice your indoor basil plant struggling, it may be due to inadequate sunlight or chilly drafts. Adjust its placement accordingly to optimize growth and overall health.

Watering and Fertilizing

Water Retention and Root Health

Watering basil is essential for keeping the plant healthy and ensuring proper growth. Basil grown in pots requires more frequent watering compared to plants grown in garden soil, as the exposed sides of the pot can cause water loss 1. To maintain the moisture in the pot, it is crucial to use well-draining soil.

To determine when to water your basil, stick your finger into the potting mix. If the soil feels dry, it’s time to add water 2. Basil is sensitive to moisture, so it’s important not to let the pot dry out completely. The ideal temperature for basil is between 50-70 degrees Fahrenheit (10-21 degrees Celsius) 3.

Types of Fertilizers

It’s essential to fertilize your basil occasionally for healthy growth and development. Typically, a balanced, granular organic fertilizer works best for container-grown basil 4. These fertilizers are made up of ingredients such as kelp meal, feather meal, guano, and others. Applying a balanced liquid fertilizer every 4-5 weeks can also be beneficial for indoor basil plants 5.

When choosing a fertilizer for your basil, consider factors like the type of basil you’re growing, the size of the pot, and the growing conditions. Opt for a high-quality, natural fertilizer that promotes healthy growth without causing root problems or leaf burn.

In summary, proper watering and fertilizing are vital aspects of caring for basil in a pot. Maintain the moisture in your potting mix and provide necessary nutrients by using appropriate fertilizers for successful growth.

Basil Plant Care and Maintenance


One of the essential aspects of basil plant care is regular pruning. This promotes healthy growth and encourages branching. To prune your basil plant, snip off the top sets of leaves just above a pair of lower leaves, allowing your plant to grow bushier rather than taller. Remember to remove any flowering stems, as they can affect the flavor of the basil leaves.

Pests and Diseases

Basil plants can experience issues with pests and diseases. Some common pests that can target your basil include aphids, spider mites, and whiteflies. To prevent these pests, ensure proper airflow around the plant and avoid overwatering. If you notice any pests, you can use a spray of water to dislodge them or try an organic insecticidal soap.

One common disease that can affect your basil plant is fusarium wilt. This can be prevented by placing mulch around the base of the plant to keep the soil moist and cool while also reducing the chance of soil-borne pathogens. If your plant does get infected, unfortunately, there’s no cure. Remove and discard the affected plant to prevent the disease from spreading to other plants.

Basil plant care also involves proper harvesting techniques. Regularly harvesting the leaves can encourage growth and keep your plant healthy. Pick leaves from the top of the plant, working your way down. This allows the lower leaves to get more sunlight and promotes branching.

In summary, basil plant care and maintenance in a pot include regular pruning, proper airflow, addressing pests and diseases, and harvesting leaves. By following these steps, you’ll be well on your way to growing a flourishing and aromatic basil plant.

Harvesting and Utilization

When to Harvest Leaves

Harvesting basil leaves is best when the plant has reached 6 to 8 inches tall, usually 60 to 90 days after planting. Keep an eye out for the fragrant, flavorful leaves. The best time to harvest is in the morning, as this is when the leaves have the highest concentration of essential oils. To harvest, simply pinch off a few leaves or snip them with scissors to avoid damaging the plant.

Using Fresh and Dried

Fresh basil leaves can be used immediately to enhance various dishes like salads, pasta, or even pizza. Make sure to rinse the leaves gently and pat them dry before use. On the other hand, dried basil leaves can be used as a dried spice to season meals and soups. To convert fresh basil to dried, simply spread the leaves in a single layer on a clean surface and let them air-dry for several days.

Preservation Methods

Basil is quite versatile and can be preserved in a couple of ways. Quickly preserving and storing your basil ensures that you always have a fresh supply of this tasty herb at hand. Here are three popular preservation methods:

  1. Freezing: Rinse the leaves, pat them dry, and place them in a single layer on a baking sheet. Once they’re frozen, transfer them to a ziplock bag or an airtight container for future use. Frozen basil leaves will maintain their fragrance and flavor for several months.
  2. Drying: Spread the basil leaves in a single layer on a clean surface and let them air-dry for several days. Once dried, store the leaves in an airtight container.
  3. Basil-infused oil: To create a delicious basil-infused oil, simply add the basil leaves to a quality olive oil and let it steep for at least two weeks. Use this oil as a drizzle on dishes, in salads, or for cooking.

Basil seeds can also be collected and used in various recipes, like drinks, desserts, or even as a healthy garnish on your favorite meals. To collect seeds, allow the flowers to dry on the plant and then gently crush the flower heads to release the seeds. Store seeds in a cool, dry place until needed.

Companion Planting

Neighboring Plants

When growing basil in a pot, it’s important to consider companion plants. These are plants that can harmoniously grow alongside basil, providing mutual benefits. Basil has several great companion options, including herbs and vegetables such as tomatoes and peppers.

Herbs make excellent neighbors for basil. Mint is a good companion, as it requires similar growing conditions and can also help repel pests. Parsley can also be grown alongside basil in pots, as both herbs thrive in similar environments when well cared for (source).

Tomatoes are a popular choice for basil companion planting. They enhance each other’s flavors and repel common pests like whiteflies, spider mites, and aphids (source). Planting these two together can improve the overall health and flavor of both plants.

In addition to tomatoes, peppers can also be excellent neighbors for basil. Just like tomatoes, they share similar growing conditions and can enhance basil’s flavor while repelling harmful insects (source).

To create a successful basil companion planting in your pot, choose neighboring plants that meet the following criteria:

  • Require of similar growing conditions (water, light, and soil requirements)
  • Enhance basil’s flavor
  • Repel pests that may harm basil

Remember to keep your basil pot well-drained and provide adequate sunlight. By taking proper care of your basil and its companion plants, you’ll soon enjoy a bountiful harvest of fresh, flavorful herbs and vegetables.
