Planting
Where to Plant Egglant
For the best results, plant eggplant in a location that gets full sun—at least 6 to 8 hours of direct sunlight per day.
Eggplants grow best in a well-draining sandy loam or loam soil that is fairly high in organic matter. To improve soil fertility, mix 1 inch of well-rotted manure, compost, or a general fertilizer such as 5-10-5 throughout the planting bed about a week before planting. (Apply 2 to 3 pounds per 100 square feet. Or, apply 1¼ pounds of 5-10-5 per 10 feet of row when the row spacing is 4 feet.) Soil pH should be between 5.8 and 6.5 for best growth.
Growing Eggplant in Containers
If you’re growing eggplant in pots, use a dark-colored container that will absorb more sunlight. Put one plant per 5-gallon (or larger) pot in full sun and outdoors so it can be pollinated. Use a premium potting mix to avoid disease. Raised beds, which warm more quickly than ground soil, are also ideal for growing eggplant.
When to Plant Eggplant
- Start seeds indoors in flats or peat pots 6 to 8 weeks prior to the last spring frost date. Seeds germinate quickly at temperatures between 70° to 90°F (21° to 32°C). Alternatively, buy 6- to 8-week-old nursery transplants just before planting.
- Do not plant eggplant transplants into the garden until well after the last threat of frost.
- If purchasing transplants: Buy high-quality specimens. Do not purchase tall, spindly plants or young plants that already have blossoms (ideally, young plants should spend energy becoming established before they begin flowering).
How to Plant Eggplant
- Start seeds indoors, sowing them ¼ inch deep in flats or peat pots.
- After the risk of the last spring frost has passed and daytime temperatures are 70° to 75°F (60° to 65°F at night), set seedlings in holes 24 to 30 inches apart in rows 3 feet apart. Use a covering of black plastic mulch to warm soils before setting out transplants if soil temperatures aren’t yet high enough.
- Immediately after planting (in-ground or pot), set 24-inch-high stakes 1 to 2 inches from each plant or use cages to provide support and avoid disturbing the soil or roots later. Eggplant will fall over when laden with fruit.
- After planting, water well. Add a layer of mulch to retain moisture and suppress weeds.
- If you live in a cold climate, consider using row covers to keep the young eggplants warm and sheltered. On warm days, open the ends of the row covers so that bees may pollinate the eggplants’ flowers.
The standard eggplant produces egg-shaped, glossy, purple-black fruit.
- ‘Black Beauty’ is the traditional eggplant size. One plant produces 4 to 6 large rounded fruit. Other regular types include ‘Black Magic’, ‘Purple Rain’, and ‘Early Bird’.
- ‘Black Bell’: classic oval to round, 6-inch, purple/black fruit; disease-resistant
- ‘Dusky’: classic pear-shaped, 6- to 7-inch, glossy purple/black fruit; excellent flavor; disease-resistant
Other interesting eggplant varieties include:
- ‘Applegreen’: oval, 5- to 6-inch, tender, pale green fruit
- ‘Bambino’: oval, walnut-size, purple/black fruit; 1 1/2-foot-tall plants
- ‘Casper’: cylindrical, 6-inch, snow-white fruit; mushroom flavor
- ‘Cloud Nine’: teardrop-shaped, 7-inch, white fruit; disease-resistant
- ‘Kermit’: Thai type; round; 2-inch, green fruit with white-striped shoulder
- ‘Rosita’: pear-shaped, 6- to 8-inch, rose-pink fruit; sweet flavor
The long, slender Japanese eggplant has a thinner skin and a more delicate flavor.
- ‘Ichiban’: 10- to 12-inch, slim, purple/black fruit; bears until frost. Expect a dozen or more fruits from one plant.
- ‘Little Fingers’: finger-sized purple/black fruit; good for containers. Small-fruited varieties tend to be especially heavy bearers.
Ornamental varieties are edible but of poor eating quality.
- ‘Easter Egg’ is an ornamental eggplant, usually white in color. (Not edible.)
Harvesting
- Harvest eggplant 65 to 80 days after transplanting, depending on the variety. When starting from seed, expect 100 to 120 days to maturity. July, August, and September (even into October) are all harvest months for eggplant, depending on where you live and the variety you planted.
- Eggplant tastes best when harvested young as soon as it’s dark and glossy purple. Fruits are ripe when their skin doesn’t rebound to gentle pressure from your finger. If you cut into an eggplant and find an abundance of brown seeds, it’s already too late.
- Harvest early and often, and the plant will be quite prolific. Once ready, check on your eggplants every 2 to 3 days.
- Japanese eggplant may be ready to harvest when the size of a finger or hot dog.
- When harvesting, do not pull the fruit (it won’t come off). With a sharp knife, cut through the tough stem above the green cap, or calyx, on the top. The calyx can be prickly, so you will want to wear gloves.
- You can cut these plants back like peppers if your season is long enough for a second crop.
How to Store Eggplant
- Eggplants can be stored for up to 2 weeks in humid conditions no lower than 50°F (10°C).
- In the refrigerator, they will keep for several days.
- Do not wash or cut in advance to avoid damaging the skin, which will quickly perish if exposed.
- To avoid discoloring of eggplant after cutting open for cooking or grilling, use a marinade with salt, vinegar, and/or lemon juice.
Cooking Notes
- Eggplant is excellent grilled, roasted, breaded, fried, or baked! The thinner varieties (‘Ichiban’) are more ideal for grilling and roasting and the traditional varieties (Black Beauty) are great breaded or fried; the round fruit is also good as a “boat” for stuffing.
- Use a stainless steel knife (not steel) to cut eggplant or it will discolor.
- If your eggplant is oversize, the skin may be too tough to eat. Peel before cooking or bake the eggplant and then scoop out the flesh. If you’re baking eggplant, first pierce the skin a few times to allow steam to escape.
- Many Italians will tenderize an eggplant so it’s less bitter. Slice them and sprinkle with salt at least 1 hour before use.

how does eggplant perform in Nakuru lanet?
We don’t have expertise growing crops in Kenya but we would think eggplant (known as biringanya or brinjal) would grow quite well in your climate. Here’s a reference page from Kenya: https://farmerstrend.co.ke/plant-biringanya-eggplants/
I have 2 plants and enjoyed many eggplants from both. The plant itself is still alive and has many flowers but no fruit is coming. Are they done for the season?
Eggplants are a warm-weather plant, so once temperatures drop below 60°F, they slow or stop production of new fruit. They are actually a perennial, but most people treat them as annuals because they are not frost tolerant. Only in the warmest regions of California and Florida can plants keep up production in the cooler months, so unless that’s where you are growing yours, they are likely done for the season.
Please i want to reference/cite this article. How can i do that
I have 2 large Asian eggplants(Solanum ferox or terong asam in Indonesian) in my office that stand about 2 feet tall and are over a year old. They seem healthy enough, with nice large leaves, but I have yet to get a flower or fruit from them. I live in a cold climate in Alberta, Canada so have to have them indoors. The pot size is about a gallon and a half. Would I need a bigger pot? I have re potted them once already. Should I pinch off the tips of young plant stems to get fruit?
Eggplants like warmth and light. When growing indoors, make sure that they get about 12 to 14 hours of light. Temperatures ideally should be 75 to 85F during the day, and not below 65F at night. A 5-gallon pot is better for the plant—each needs at least about a square foot of growing space in the container for the roots. When flowers do form, you’ll need to shake the plant daily to help the pollen fall from anther to pistil in each flower. You can try pinching the tips of the plant to encourage bushiness; more branches on the plant means more potential for flowers. However, if you are planning to repot, perhaps wait to pinch until later, after the plant has re-established itself.
I live in Zone 9b and was wondering if I can sow some eggplant seeds now. My idea being they will grow and establish themselves until Spring next year and be ready to flower and fruit quickly next year.
In Zone 9, the climate is mild so you do have a long planting season, but the best range for eggplants is February through July.
I noticed the cuc first so I covered it with a milk crate w which worked out perfectly. But then I noticed tonight many leaves off of my eggplant are missing so I covered over I covered over the Cucumber but now I don't know what to do about the eggplant which is in a separate pot all by itself can someone please help?
