Companion Plants for Eggplant in Containers

The Importance of Companion Plants for Eggplant

Growing eggplants in containers can be a fun and rewarding experience, but it can also come with its own set of challenges. One way to mitigate these challenges is by using companion plants. Companion planting is the practice of growing different plants together that have beneficial effects on one another. In the case of eggplants, companion planting can help with pest control, soil nutrition, and overall plant health.

Choosing the Right Container for Eggplant

Before we dive into companion planting, it's important to select the right container for your eggplant. Eggplants need a container that is at least 12 inches deep and 18 inches wide. They also require well-draining soil and a location that receives at least six hours of sunlight per day.

Types of Containers

You can choose from a variety of containers for your eggplant, including:

• Terra cotta pots

• Plastic containers

• Fabric grow bags

• Self-watering containers

Each type of container has its own advantages and disadvantages. Terra cotta pots are attractive, but they dry out quickly. Plastic containers are lightweight and easy to move, but they can become brittle over time. Fabric grow bags are affordable and offer good drainage, but they may not last more than one season. Self-watering containers are convenient, but they can be expensive.

Maintenance Tips for Companion Planting

2. Fertilizing

Add a slow-release fertilizer to your container at the beginning of the growing season to provide nutrients to all of your plants.

3. Pruning

Prune your companion plants regularly to prevent them from becoming too large and crowding out your eggplants.
