Did You Know?
1. Eggplants are believed to have originated in India over 4,000 years ago and were initially cultivated for their seeds. It wasn’t until centuries later that they started being grown for their fruit.
2. Eggplants belong to the nightshade family along with tomatoes, peppers, and potatoes.
3. Contrary to popular belief, eggplants are not vegetables but rather fruits. As per botanical definition, fruits are developed from the ovaries of flowers and contain seeds.
4. The world’s largest producer of eggplants is still India, where it is a staple in various regional cuisines.
5. Eggplants come in a wide variety of shapes and sizes, from the traditional large and bulbous dark purple ones to smaller, elongated varieties like the Japanese or Italian eggplants, which are also popularly used in cooking.
Choosing And Starting Eggplant Plants
Eggplants, like many other warm weather crops, require specific care and attention to ensure optimal growth and productivity. It all starts with choosing the “right plants“. When buying eggplant plants, it is important to select “sturdy ones that are up to a foot tall“. This ensures that they have a strong root system and are capable of withstanding the transplantation process.
In addition to selecting healthy plants, it is also crucial to “start eggplant seeds about eight weeks prior to planting them outside“. This allows the seeds to germinate and develop into healthy seedlings. Starting the seeds indoors provides a controlled environment that ensures the ideal temperature and conditions for seedling growth.
To successfully care for eggplants, follow these key steps:
- Choose sturdy eggplant plants that are at least a foot tall.
- Start eggplant seeds indoors approximately eight weeks before transplanting.
- Provide a controlled environment to promote seedling growth.

Transplanting And Supporting Eggplant
After the nighttime low temperatures have consistently risen above 50°F, it is time to transplant the eggplant seedlings outdoors. However, before transplanting, it is necessary to install plant supports to provide the necessary structure and stability for the growing plants. These supports can be in the form of stakes, cages, or trellises, depending on your preference and the specific needs of your eggplants.
To minimize root damage and maintain warm soil temperatures, it is recommended to use mulch around the eggplant plants. Mulch not only helps to retain moisture but also acts as an insulating layer, protecting the roots from extreme temperatures.
Soil Preparation And Fertilization For Eggplant
Proper soil preparation and fertilization are essential for the successful growth of eggplants. The ideal pH range for eggplant cultivation is between 5.5 and 7.5. Conducting a soil test can help determine the exact pH and guide the application of phosphorus and potassium according to the specific needs of the soil.
To improve the soil quality, incorporating well-rotted manure or compost is highly beneficial. These organic amendments provide essential nutrients, enhance soil structure, and promote overall plant health.
However, it is important to avoid excessive nitrogen fertilization, as it can result in excessive foliage and reduced fruit production. Furthermore, it is crucial to refrain from using fertilizers that contain weed killers, as they can harm the eggplant plants.
Here are some additional tips for successful eggplant cultivation:
- Regularly check and maintain the soil pH between 5.5 and 7.5
- Use organic fertilizers, such as compost or well-rotted manure
- Avoid over-fertilizing with nitrogen to prevent excessive foliage
- Choose fertilizers that do not contain weed killers

Watering And Sunlight Requirements For Eggplant
Consistent and appropriate watering is essential for the optimal growth and development of eggplants. It is important to water thoroughly, especially during dry periods, to ensure the plants receive at least one inch of water per week. However, it is crucial to avoid overhead sprinkling, as this can promote disease development. Watering at the base of the plants promotes deep root development and prevents moisture-related issues.
In terms of sunlight requirements, eggplants thrive in a sunny environment. They need a minimum of a couple of hours of direct sunlight per day. Gradually exposing the seedlings to increasing sunlight over a period of one to two weeks prior to transplanting them outside helps acclimatize them to the environmental conditions. Additionally, providing bright overhead light for the seedlings indoors ensures their robust growth.
Harvesting And Caring For Eggplant
Knowing when and how to harvest eggplants is crucial to maximize their flavor and quality. Eggplants should be harvested when they have reached their mature size and exhibit a shiny skin and firm texture. Using sharp shears, cut the fruit from the plant to avoid damaging the rest of the plant. Leaving fruit on the plant during cold nights can result in injury, so it is advisable to cover the plants if there are low temperatures.
Caring for eggplants also involves addressing common plant health issues. Changes in leaves, flowers, and fruit can be caused by various environmental factors, diseases, insects, and wildlife. Prompt and accurate diagnosis is essential to effectively address these issues. Proper cultural practices, such as adequate plant spacing, pruning, rotational planting, and watering at the base of the plants, can help prevent many plant diseases. While Verticillium wilt is the most common eggplant disease, causing yellowing and curling of leaves, early blight is not as common but can still infect the plants.
To achieve optimal growth and productivity when planting eggplants, it is crucial to consider various factors such as choosing sturdy plants, starting seeds at the right time, transplanting and supporting the plants, preparing the soil and applying appropriate fertilization, providing adequate watering and sunlight, and properly harvesting and caring for the eggplants. By following these guidelines and implementing proper care and maintenance, gardeners can enjoy a bountiful harvest of delicious and healthy eggplants.

Frequently Asked Questions
What should you not plant next to eggplant?
It is advisable not to plant eggplants next to heavy feeders like corn, melons, and plants from the squash family, as they compete for nutrients and may result in stunted growth. Additionally, geraniums should also be avoided, as they may carry pathogens that can negatively affect the growth of eggplants.
How far apart do you plant eggplant in a market garden?
For optimal growth and productivity in a market garden, it is recommended to plant eggplants approximately 45 – 60 cm apart within the row, while ensuring a gap of 75 – 90 cm between rows. Adequate spacing allows each plant to receive sufficient sunlight, airflow, and nutrients, stimulating healthy growth and preventing the spread of diseases. To further support the development of robust root systems, it is advisable to water-in the transplants with a starter fertilizer that contains a higher level of phosphorous. This nutrient stimulates root growth, enabling the plants to establish themselves quickly and efficiently in the garden.
How do you increase eggplant yield?
To increase eggplant yield, a proven method is to invite native pollinators to the garden. While wind alone can fertilize self-fertile eggplant flowers, the intervention of bees, particularly solitary ones like carpenter bees, bumblebees, and little sweat bees, can greatly enhance fruit set and size. These bees engage in buzz-pollination, vibrating the blossoms to effectively shake out pollen, thus optimizing the chances of successful pollination and yielding a higher crop. Creating a welcoming environment for these native pollinators can ultimately result in a bountiful eggplant harvest.
Can I plant just one eggplant?
Yes, it is possible to plant just one eggplant in a container. It is recommended to use a 12- to 14-inch container for a single eggplant, ensuring adequate space for its growth. Alternatively, a larger 20-inch pot can accommodate up to three eggplants if you wish to grow more. Whichever option you choose, remember to use high-quality potting soil and plant the eggplant at the same depth as it was in its nursery pot.
