Why use a greenhouse to grow eggplants?

Eggplants need a long growing season, about 3-4 months, like tomatoes and peppers. If your season is short, growing them outside might be tricky.

 But fear not! A greenhouse can help. Start seedlings indoors about 2 months early and then transplant them outside once the frost is gone. Or, keep them in the greenhouse for extra protection. 

Greenhouses extend the growing season and shield plants from pests and bad weather, giving eggplants a boost in growth and protection.

Ready to grow your eggplants? Whether from seeds or nursery starts, keeping them healthy is key for big, tasty purple fruits. Let’s dive in.

Requirements of Light

Eggplants, like tomatoes, need full sun for 6-8 hours daily. Plant them where they’ll get plenty of sunlight. If your greenhouse lacks sunlight, use grow lights to supplement.


Eggplants thrive in warm climates, ideally between 80-90 degrees Fahrenheit.

At night, keep the greenhouse above 65 degrees for proper fruit development. Warmth is crucial when starting seeds; use a heat mat to keep soil warm in seedling flats.


While greenhouses keep pests out, they also block pollinators like bees.

But do not worry! Eggplants are self-pollinating, meaning they can pollinate themselves using their flowers.

You can still help by opening the greenhouse during flowering or using a fan to stimulate pollination.

Common Diseases and Pests that Affect Eggplants

In a greenhouse, eggplants face fewer pest issues but watch out for blight and bugs. Blight is a fungus that can be controlled by removing infected plants and ensuring good ventilation.

Bugs like flea beetles, Colorado potato beetles, tomato hornworms, and whiteflies can also be a problem. Keep your greenhouse tidy and consider planting native plants to deter pests.

When to decide to harvest eggplants 

Want to harvest your eggplants? They’re tastiest when young. Press gently; if skin yields and the color is even, it’s time to pick. Cut near the stem to avoid damage. Enjoy your home-grown eggplant.
