Everything you need to know to grow eggplant

Black Beauty eggplant in container with petunias

Eggplant is easy to grow.  It is happy in a pot or the ground.  Eggplants are tropical plants and require a long growing season to fruit.  Large eggplant varieties are stunning plants in pots with their upright habit and large leaves.  I like to pair them with petunias on the patio and deck. 

Eggplant is a staple in Greek, Italian, Middle Eastern and many Asian cuisines.  It is used as a substitute for meat in many dishes.  This fruiting vegetable originated in India and has been cultivated there for thousands of years.  It had made its way to the Mediterranean region by the Middle Ages.  

Eggplant contains fiber, antioxidants that have potential health effects against cancer, C, K, folate vitamins, and copper, iron, magnesium and potassium.  eggplant nutrition info

 Ideally, eggplant should be started indoors 6-8 weeks prior to the last frost date (for Zone 7, this is end of February/first of March).  They are heat loving veggies that need some time to start producing fruit.  If you don't get them started early or just want the convenience, there are many varieties available at nurseries and big box stores.

Transplant outdoors after all danger of frost has passed, 18-24" apart in full sun.  Fertilize when transplanting with a balanced organic/all natural fertilizer.  Fertilize again with the first flowers appear to support the growth of fruits, then monthly if planted in the garden bed.  For those planted in pots, I add solid fertilizer monthly and give a liquid fertilizer when I water every 2 weeks.  The plants like moisture so don't be stingy with water.

Eggplants, like peppers and tomatoes, are perennials.  You can bring them indoors at the end of the season and with direct sun, continue producing.  If they survive the winter, they will produce sooner and have bigger yields next summer.  I have had mixed luck overwintering mine in our unheated garage.  This winter, my white eggplant overwintered well inside the house in a southern window.  I have already started harvesting its fruits.

Eggplants grow well in pots.  This is my preferred way to grow eggplants.  Look for dwarfs or patio types like Casper, Listada de Gandia, White Egg or Fairytale, or plant in a larger container.  

If you have grown eggplant in the past and experienced a tough outer skin, slight bitterness of taste and many seeds, you need to pick the fruits sooner.  As the fruits ripen on the vine, they will get a thicker skin, more and larger seeds.   You can also look for varieties that are better adapted to hot and humid climates.  

We have found any white fruiting eggplant work great in our hot and humid summers.  They don't get bitter and their skins don't get tough.  Rosa Bianca and Amadeo have also stayed sweet with thin skins. This year, I am growing White, Italian Pink Bicolor, Rotanda Bianca, Mitayo, Amadeo, AO Daimara, and Turkish Orange in pots.  Turkish Orange has a smokey flavor and smaller orange fruits. It's fun to try new varieties while keeping proven performers.

I use Espoma vegetable fertilizer on all my vegetables, fruits and potted plants.  Before I moved, I could also get Re-Vita fertilizer which is also a good organic fertilizer.  You can also make your own all natural fertilizer pretty economically.  Make your own all natural, complete fertilizer

All 6 newly transplanted eggplants are growing well now that it has heated up.  I got started much later this year than typical because we had a long, cool spring again this year.  Eggplants are heat lovers so I wait until it is at least up in the 70's before I transplant outdoors.  

When fruits come on, be sure to harvest regularly.  There are 2 good reasons.  One-the more you pick, the more the plant produces.  Two-the fruits are sweeter and skins thinner on younger fruits.

The only pest I've found with eggplants are flea beetles.  They seem to just love the White eggplant leaves.  They eat them until there is hardly anything left but the veins.  I tried to let the pest "come in balance" and didn't treat with anything, but afte 5 years with no slowing in sight I started using insecticidal soap to knock them back last year.  Plants need their leaves to produce food for the plant and its fruits!  You might also be able to use nasturtium as a decoy plant to attract the flea beetles away from the eggplants.  This has not worked for me to date.

Eggplant can be baked, steamed or grilled.  My favorites are brushing on olive oil and salt and grilling until tender, stuffing and baking, using as lasagna noodles, or slicing and topping with parmesan cheese and backing until the cheese is crisp.  I do the same with zucchini.  Keep the grill temp below 350 or substitute grape seed oil that has a higher smoke point.

I have tried blanching eggplant and freezing them.  They just don't taste the same.  Last year, I grilled them and then made them into dip.  After frozen, the dip still tasted great.  I'll do the same with any extras I have this year.

We love both eggplant and zucchini grilled.  Here are the recipes I use for eggplant and zucchini  What to do with all that zucchini?!
