Eggplant Plants - How Long Do They Live

Planting Eggplant From Seed

Eggplants take a relatively long time from planting to maturity.  They also do not thrive in cool weather.

If you plan to grow eggplants from seed, you will need to start them indoors at least 8 to 10 weeks before your region’s average last frost date.

Seeds and seedlings require warm soil to germinate and grow quickly. The best soil temperature for germination should be between 70 and 90 degrees F.

Ensure you plant your seedlings in the warmest location in your home or use a heating mat to warm your soil.

Growing Eggplant Plants As Transplants

If you plant eggplants from transplants, ensure you do so after the danger of frost has passed and the soil is warm enough.  The daytime temperatures should be at least 70 to 85 degrees F.  Any light frost can severely damage the transplants, so be sure that the frost days are over.

Cool temperatures slow down growth significantly, so to overcome this, keep your transplants indoors until the weather warms up. Remember to use big containers when the plants are indoors to avoid overgrowing the small pots or planting them outdoors too soon.

If you are purchasing transplants from a garden centre, do not buy them until the final frost date has passed. Choose plants with dense and compact growth, avoiding those that already have blossomed.

Blossoms already on seedlings may slow the growth after transplanting and lead to fewer or smaller eggplants at harvest.

Common Cultivars To Select

Eggplants have different cultivars to choose from when you want to grow your own.  The common varying shades of purple, white, green and yellow, green come in a multitude of shapes and sizes enjoyed worldwide. Let’s look at the most common ones.

  • Black Beauty.  This is the commonly known variety that has been grown for over a century.  It bears 6-inch dark purple fruits making it favourable to most gardeners.   It has an attractive yield of 4 to 6 fruits per plant.
  • Gretel.  This variety is a 2005 all American winner that produces white fruits.  The fruits of this variety are 3 to 4 inches long with few seeds and no bitter taste.   The fruits are sweet and tender skinned.  This variety is best for container gardening as they grow only to 2 ½ feet tall and wide.

Harvesting Your Eggplant

Having seen that the timing of your harvest depends on the particular variety of the eggplant you are growing, let’s learn about harvesting.

Eggplants fruits taste the best when harvested before they reach full maturity.  When they are ready for harvest, the skin will have a glossy look, the flesh will be cream coloured, and the seeds will not be fully developed or very small.

If you harvest the eggplants when they are about half the expected mature size, it encourages them to produce more fruit. If you wait too long to harvest, the skin may become dull and tough, and there may be abundant seeds.

The eggplant plants live through one season.  After harvesting the final fruits, the plant dies, and it’s time to plant new one’s next season.
