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.

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. [Images]
Hot 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.

-
Tomato
Hornworms

-
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.

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
