Starting From Seed Vs. Buying Seedlings

Starting From Seed Vs. Buying Seedlings

Starting from seed offers greater control over the growing process, allowing gardeners to nurture the plant stems right from the beginning. On the other hand, buying seedlings can save time and reduce the risk of failure since they already have a head start.

It’s important to consider the cost and availability of seeds versus seedlings, as well as the wider selection of eggplant varieties available when starting from seed. However, starting from seed does require more time and effort compared to buying seedlings. Ultimately, choosing between starting from seed and buying seedlings depends on individual preferences and circumstances.

Planting In Containers Vs. In The Ground

When it comes to growing eggplants in a greenhouse, you have the option of planting them either in containers or in the ground. Planting them in containers offers easy maintenance and allows for better control over soil conditions. On the other hand, planting them in the ground provides more space for growth and ultimately leads to a larger yield. Containers are ideal for smaller greenhouses or limited spaces, while ground planting suits larger greenhouses or outdoor gardens. When deciding between the two, it’s important to take factors such as soil quality and drainage into consideration.

How To Care For Eggplants Grown In A Greenhouse

How To Care For Eggplants Grown In A Greenhouse

To care for eggplants grown in a greenhouse, choose the right variety that thrives in protected environments. Provide adequate light and temperature control to ensure optimal growth. Maintain the proper soil conditions by using quality fertilizers and organic matter like manure.

Regularly monitor for pests and diseases, like aphids or fungal infections, and take necessary measures to control them. Additionally, properly train and support the plant stems to prevent breakage and maximize yield. By following these guidelines, green-thumb gardeners can enjoy a bountiful harvest of delicious eggplants in their greenhouse.

Light Requirements

To ensure successful greenhouse eggplant cultivation, it is essential to provide proper sunlight or grow lights. Eggplants thrive in full sun, so it’s crucial to ensure adequate light exposure. This can be achieved by using grow lights or placing the greenhouse in a location that receives ample sunlight.

In temperate climates, greenhouse crops can be utilized to grow eggplants year-round. To optimize growth, greenhouse eggplants require a minimum of 6 hours of direct sunlight daily. Additionally, adjusting the temperature difference within the greenhouse can further enhance eggplant growth.


To ensure optimal eggplant germination, maintain a temperature range of 70-85°F in your greenhouse. Greenhouse eggplants thrive when the relative humidity is between 40-70%. During eggplant fruit maturity, aim for a temperature of 75-85°F. To promote healthy growth, it’s ideal to have a temperature difference of 10-15°F within the greenhouse. This temperature variation helps mimic natural outdoor conditions. By using a greenhouse, you can protect your eggplants from extreme temperature fluctuations that could hinder their growth.


To facilitate pollination in a greenhouse, growers can introduce pollinators like bumblebees to their eggplant crops. Alternatively, hand pollination can be done using a sharp knife or a paintbrush. Maintaining a temperature of 75-85°F is crucial for optimal pollination and fruit set of greenhouse eggplants.

Pollination is essential as it leads to a bountiful harvest of delicious eggplants. By following these pollination techniques, gardeners can give their greenhouse eggplants a head start and ensure a successful harvest without relying solely on natural pollinators.

When it comes to harvesting eggplants grown in a greenhouse, timing is crucial. To ensure that you harvest your eggplants at the right time, keep a few key indicators in mind. Wait until the eggplants reach their full maturity before harvesting them. A good rule of thumb is to pick them when the fruit diameter is around 2-4 inches.

For the best flavor and freshness, consider harvesting in the morning. Look for a dark, glossy shade on the stalk color of the eggplant fruits, as this is a sign of readiness. For a bountiful yield, September to November is the ideal time to harvest greenhouse-grown eggplants.


Growing eggplants in a greenhouse offer numerous benefits, including extended growing seasons, protection from pests and diseases, and better control over environmental conditions. When choosing the right variety, consider factors such as size, taste, and intended use.
