Companion planting is an ancient gardening practice that involves growing different plants together to improve their growth, health, and productivity. Two popular herbs that are often considered for companion planting are rosemary and basil. Both herbs are widely used in cooking and have unique growing requirements. In this article, we will explore the possibility of planting rosemary and basil together, discussing their growth habits, space requirements, and potential benefits and drawbacks of companion planting.
Understanding Rosemary and Basil
Before we dive into the details of planting rosemary and basil together, it’s essential to understand the characteristics of each herb. Rosemary is a perennial herb that belongs to the mint family. It is a low-maintenance plant that prefers well-drained soil and full sun. Rosemary can grow quite large, up to 6 feet tall, and has a sprawling habit. It is also a drought-tolerant plant, making it an ideal choice for water-conscious gardeners.
On the other hand, basil is an annual herb that belongs to the mint family as well. It prefers well-drained soil and partial shade to full sun. Basil is a relatively small plant, growing up to 2 feet tall, and has a compact habit. It requires consistent moisture and is sensitive to extreme temperatures.
Growth Habits and Space Requirements
When considering planting rosemary and basil together, it’s crucial to think about their growth habits and space requirements. Rosemary, as mentioned earlier, can grow quite large, while basil is relatively compact. If you plant them together, you may need to provide support for the rosemary to prevent it from overshadowing the basil.

Can I plant rosemary and basil together in the same container?
When it comes to growing rosemary and basil together, it’s essential to consider their different growing requirements. Rosemary is a perennial herb that prefers well-draining soil and full sun, while basil is an annual herb that thrives in moist soil and partial shade. If you’re planning to grow them in the same container, make sure it’s large enough to accommodate both plants’ root systems and provides good drainage. You’ll also need to choose a location that receives plenty of sunlight, but also offers some shade to protect the basil from scorching.
To increase the chances of success, select a compact or dwarf variety of rosemary that won’t overshadow the basil. You can also plant the rosemary towards the back of the container and the basil towards the front, allowing the basil to receive more sunlight. Keep in mind that rosemary can be quite potent and may compete with basil for water and nutrients. Regularly fertilize and water your plants, and make sure the soil doesn’t dry out completely. With proper care and attention, you can enjoy the benefits of growing rosemary and basil together, including improved flavor and fragrance.
What are the benefits of planting rosemary and basil together?
Planting rosemary and basil together can have several benefits, including improved flavor and fragrance. Rosemary’s piney flavor can complement basil’s sweet and spicy flavor, making them a great combination for a variety of dishes. Additionally, rosemary’s tall, upright growth can provide support for basil, which can help keep it from becoming leggy or top-heavy. Basil, on the other hand, can help to repel pests that might be attracted to rosemary, such as carrot flies and mosquitoes.
Another benefit of planting rosemary and basil together is that they can help to improve each other’s growth and health. Rosemary’s deeper roots can help to bring up nutrients from the soil, making them available to the basil. Basil’s shallow roots, on the other hand, can help to retain moisture in the soil, reducing the need for frequent watering. By planting them together, you can create a symbiotic relationship that benefits both plants and adds to their overall health and productivity. With proper care and attention, you can enjoy a bountiful harvest of fresh rosemary and basil all season long.
Do rosemary and basil have the same growing requirements?
Rosemary and basil have different growing requirements, which can make it challenging to grow them together. Rosemary prefers well-draining soil and full sun, while basil prefers moist soil and partial shade. Rosemary is also more drought-tolerant than basil, which requires consistent moisture to thrive. Additionally, rosemary is a perennial herb that can grow quite large, while basil is an annual herb that typically grows to be around 1-2 feet tall.
Despite their differences, you can still grow rosemary and basil together with proper care and attention. Make sure to plant them in a location that receives plenty of sunlight, but also offers some shade to protect the basil from scorching. Use a well-draining potting mix and fertilize regularly to promote healthy growth. Water your plants when the top inch of soil feels dry to the touch, and avoid getting water on the leaves to prevent fungal diseases.
