How to Grow Eggplant

Homegrown Eggplant by Abigal Gordon

Online Fact Sheet

 

 

Eggplants were once considered a Sexy Fruit. They were called "apples of love" by the Portuguese and Spanish . Medieval Europeans believed that eggplant was an aphrodisiac.  Botanists once classified them as " Mala insana,"  -"mad apple,"- there was a belief that consuming Eggplant would cause insanity.

In modern times they serve as an excellent meal, and are quite frequently used as a meat substitute. They are a favorite of many North American Gardner's

 

 


Planting Eggplant

Eggplant grows best in a well-drained sandy loam or loam soil, fairly high in organic matter.

Start early indoors in peat pots or cell packs

Rows should be 3 to 5 ft. apart. Plants should be 2 to 3 ft. apart

Transplants should be 8 to 10 wks old and slightly hardened, grown in 2 inch. or larger pots.

The outdoor environment can be very harsh for a transplant. So, harden the transplants before planting outdoors to increase their survival rate. Place them outdoors in their original containers where they will receive direct sunlight and some wind for a few hours each day for a week, possibly more.. Gradually lengthen the amount of time outside each day. Move the plants inside at night .

 

Climatic Requirements for Eggplant

The eggplant is a very tender plant that requires a long, warm season for successful production. The plants are killed by light frost and are injured by long periods of chilly, frostless weather. Plants should not be set out until all danger of frost has passed, and should be hardened first [See Above paragraph]

Set plants in the field when frost danger has passed, when the soil has warmed, and when the average daily temperature reaches 65°F.  [See USDA Zone Map]


 

Common Varieties of Eggplant 

 

As with any popular plant there are dozens of Hybrid Garden varieties and a healthy handful of heirlooms on the Market.  Eggplants come in numerous shapes and colors.

 

The following are my personal favorites, you of course may prefer to scan any of the many online nurseries and seed catalogs.

 

Black Beauty Eggplant Popular variety yields 5-7" fruits per plant. 1-3 pound purplish-black, glossy fruits have great flavor and hold up well after being picked. Rounded oval fruits are smooth to slightly pleated. Best started indoors 4-6 weeks before the last frost date and transplanted into rows 18-30 in. apart in the garden when the soil is warm. Needs warm conditions day and night to germinate

Snowy White Eggplant Native to India with small, white, smooth-skinned is one of many domesticated eggplants. Has an Italian-style shape and creamy texture. Planting Depth: 1/4" Soil Temp. for Germ.: 75-90°F

Italian Long Eggplant    A/K/A 'Melanzana Viserba Lunga' Cylindrical, glossy purple skinned fruits with bitter free flesh.

Toga Striped Eggplant Stunning striped fruits are 1" wide by 3" long. The fruits turn from two-toned green to two toned orange. Holds very well in fresh or dried arrangements or good to eat. Strong flavored fruits, but not bitter.

Companion Planting and Crop Rotation in Eggplants

 

Three - Four-year rotations with non-related crops and using plants grown from disease-free seeds will help control most diseases.

 

Avoid  Tomatoes, potatoes, peppers, okra, raspberries, or strawberries in rotation with Eggplant.

 

Try planting Fennell, Basil, and Lettuce (Not Cabbage) in proximity to Eggplant...also lots of Marigolds.  

 

See : Companion Planting

 

Water Requirements

Water eggplant sufficiently to moisten the soil to a depth of at least 6 inches. The critical period for moisture is during fruit set and fruit development. Mulching can help to provide uniform moisture, conserve water and reduce weeds.  Eggplants should receive slightly more than an inch of water weekly  slightly more in sandy soils. Inexpensive Water timer systems are available

 

 

Fertilizer & Soil  Requirements

Soil pH range  5.5 - 6.0  See Soil Ph for more extensive data.  

Lime and fertilizer applications are best based on a soil test. In general, two pounds each of actual nitrogen, phosphorus (P2O5), and potash (K2O) per 1,000 square feet of garden space is adequate. An additional application of one pound of actual nitrogen per 1,000 sq. ft. after the fruit has set may be helpful to maintain plant development.

 

Garden SolutionsŪ Vegetable Food All-natural plant food promotes vigorous, healthy growth of peas, and other vegetables. Releases nutrients gradually, as plants need them. Mix into soil after seeds have sprouted, again in mid-season.
 

 

Common Pests & Pathogens

Pests

  • Aphids are Yellowish-pink to pale green plant lice that suck ......plant juices. They are a soft-bodied, oval/pear shaped insect and are commonly found on nearly all varieties of plants, vegetables, field crops, and fruit trees. [ImagesHot Pepper Wax repels bugs from your plants, fruits and flowers. 100% natural spray uses pepper extract and wax to effectively discourage pests. Helps to reduce stress on cuttings.

  • Beetles Colorado Potato Beetle,  Flea beetle

  • Mites   Tomato Russet Mite, Spider Mites

  • Root Knot  Nematodes are microscopic worms that infect plants and cause swelling on the roots and stems, and small knots on the roots [Images]. When infected, the plants will wilt. Garlic as a companion not only repels vampires and the opposite sex but is said to repel nematodes as well. Crop rotation is also vital in avoiding nematodes. Once infested Predator Nematodes will control the populations of parasitic nematodes.

  • Thrips  [Images]

  • Tomato Hornworms [Image]

  • Pepper Maggot Infestations can be patchy and sporadic even in locations where there is a history of such infestations. To reduce populations, sanitation and crop rotation is helpful. Pick up any fallen peppers and destroy them. Destroy any horse-nettles [Images] in the vicinity as they are also host plants to the Pepper maggot..
     

     

Common Eggplant Diseases

Preventive Maintenance / Effective methods to avoid and control disease in your Garden

Phytophthora Blight  -[Image]

Avoid water-logged root zones - Grow eggplant in well drained fields. Planting on raised beds will increase soil drainage. Water management is of primary importance for controlling Phytophthora blight. Rotate infested fields with other non-host crops for several years

Phytophthora blight attacks the roots, stems, leaves, and fruit.  An unsuspecting grower will  first encounter the disease at mid-season. Sudden wilting and death occurs as the plants reach the fruiting stage   Often a number of plants in a row or in a roughly circular pattern will show  symptoms at the same time.

See: Cornell University Phytophthora Blight of Cucurbits, Pepper, Tomato, and Eggplant

 

Verticillium Wilt

 Verticillium wilt starts with a general or blotchy yellowing of the lower leaves and a wilting of youngest shoots in direct sunlight. At first, the wilted shoots may recover over night. The leaf veins turn brown, followed by shoots browning and lower leaf drop. Leaves higher up on the plant turn dull green in color and the edges curl upwards. Plants are stunted and defoliated with only the growing tips remaining green. The fruits are small and may sunscald. The branches tend to be less erect than those of healthy plants, giving Verticillium-infected plants a prostrate appearance. When the stem is cut open, the the water conductive plant tissues may be brownish near the soil line.
 

Soil rot, is caused by the a soil-borne fungus and generally occurs during rainy periods. A soft brown rot develops, usually on the sides of fruits touching the ground, or where soil is splashed onto them. The spots are sunken, large, and may have a closely-spaced bulls eye pattern . Sometimes the eggplant cracks open. Staking will reduce soil rot by keeping fruit away from the ground.

Blossom end rot.

This disorder occurs as a slight discoloration or a severe dark sunken lesion at the blossom end; it is caused by temporary insufficiencies of water and calcium and may occur under high temperature conditions when the peppers are rapidly growing. Recommended treatment Blossom-End Rot Control

 

Disease problems can be greatly Reduced with a combination of practices that include:

Purchase vigorous, healthy plants from a reputable supplier. Eggplants, being susceptible to

diseases, viruses and insects, some varieties have been bred or hybridized to be resistant to certain

pests. Resistance to these pests is usually listed on the plant label using the following abbreviations:
 

  • V = Verticillium Wilt

  • F = Fusarium Wilt

  • FF = Fusarium Wilt race 1 and 2

  • N = Nematode

  • T = Tobacco Mosaic Virus

  • A = Alternaria (Early Blight)

  • TSW = Tomato Spotted Wilt

     

Remember that resistance to these problems does not mean they are 100 % immune,

good cultural practices are still important.
 

  • Crop Rotation in your garden planting area

  • Remove and destroy all plant refuse in the fall and use deep cultivation to bury any remaining

    refuse.

  • Do not place diseased plants in the compost heap, as this will only serve to carry bacterial or

    fungal infestation into the next growing season

  • Avoid over watering . Use surface watering methods. Do not handle plants when the vines are wet.

  • Weeds compete with vegetables for soil moisture and nutrients and also serve as hosts for insects

    and disease carrying bacteria and fungus. Control weeds in and around  the garden

  • Control insect pests such as aphids, which are known to transmit diseases  from plant to plant.

  • Use plastic or organic mulches to reduce disease and blossom-end rot problems.

  • Choose a sunny location for your plants. Leaf disease problems are much less likely  to occur in a

    sunny location than in a shady one.

  • Apply  recommended fungicides according to label directions at the first sign of leaf spot diseases

  • Remove abnormal or unhealthy appearing plants as soon as they are observed.  To reduce the

    spread of suspected diseases wash hands and tools with a mild detergent after handling suspect plants.

Post Harvest

Eggplant is not suitable for drying or canning. Freezing is the best method for home preservation.

To Freeze: Harvest before seeds become mature and when color is uniformly dark.

Wash, peel if desired, and slice 1/3-inch thick. Prepare quickly, enough eggplant for one blanching at a time. Water blanch, covered for 4 minutes in one gallon boiling water containing 1/2 cup lemon juice (fresh or bottled). Cool, drain and package, leaving 1/2-inch head space. Seal in zip closure freezer bags and seal and freeze.

For frying -- Pack the drained slices with a freezer wrap between slices. Seal and freeze. See our recipes section for extensive ideas
