Why Are Eggplants Flowering but Not Fruiting? Causes and Solutions
Growing eggplants (Solanum melongena)—also known as Brinjal in South Asia and some parts of Africa—can be incredibly rewarding. Those deep purple fruits are not only beautiful but also delicious. Yet one of the most frustrating problems for gardeners is when eggplants are flowering but there is no fruit. You see dozens of healthy blooms, but no fruits ever form—or worse, the flowers simply drop off.
In this guide, we’ll break down the possible causes of this issue and walk you through practical solutions so you can turn those blossoms into a harvest of flavorful eggplants.
But before we get into the reasons eggplants might not be fruiting, it’s important to understand their typical growth timeline. According to University of Maryland Extension, most eggplant varieties take around 55 to 80 days from transplanting to produce mature fruit.
If you’re starting from seed, add another 6 to 8 weeks to account for germination and seedling growth before they’re ready to be planted outdoors. This timeline can vary slightly depending on the specific variety and your local growing conditions.
Eggplants are flowering but not producing fruit? Discover the causes and solutions below.
1. Poor Pollination
Let’s begin with the most common culprit: pollination problems.
Eggplants, like tomatoes and peppers, are self-pollinating. This means each flower has both male and female parts, and technically, it doesn’t need another plant nearby to produce fruit. Still, for fruit to actually form, pollen must be transferred from the anther (the male structure) to the stigma (the female part) within the same flower.
In outdoor settings, gentle wind or pollinating insects such as bees typically help move the pollen. But when pollination doesn’t happen—especially in very hot, humid, or indoor conditions—you’ll see flowers open and fall off without producing fruit.
Solutions:
- Hand-pollinate your eggplant flowers. Use a small brush, cotton swab, or even your fingertip to gently move pollen inside each flower.
- Gently shake the plant in the morning when the flowers are open—this mimics natural pollination.
- Attract pollinators by planting bee-friendly flowers nearby, like borage, marigold, or lavender.
How to know if eggplant flower is pollinated?
Well, your pollinated eggplant flower will begin to wilt and close shortly after blooming, usually within a day or two. The key sign is the small swelling at the base of the flower—this is the ovary starting to develop into a fruit. If pollination was successful, this swelling will continue to grow over the next few days.
However, if the flower stays open too long, turns brown, and drops off without any swelling, it likely wasn’t pollinated. Keep an eye on this subtle change to catch problems early.

3. High Temperatures and Heat Stress
Temperature stress is another major reason your eggplants may bloom without forming fruit. Eggplants love heat, but even they have limits.
Problems Arise When:
- Daytime temps rise above 95°F
- Nighttime temps stay above 75°F
Extreme heat can cause the pollen to become sterile or reduce flower viability, resulting in poor fruit set.
Solutions:
- Provide shade cloth during peak afternoon heat.
- Water early in the day to avoid additional stress.
- Use mulch to cool the soil and retain moisture.
4. Flowers Falling Off (Blossom Drop)
If your eggplants are flowering but not fruiting and the blooms are dropping off, you’re likely dealing with a condition called blossom drop.
This happens when the plant decides to abandon its flowers due to environmental or physiological stress. It’s a survival move.
Possible Causes of Blossom Drop:
- Sudden temperature changes
- Too much or too little water
- Nutrient imbalances
- Lack of pollination
Solutions:
- Maintain steady moisture in the soil—don’t let it dry out too much or become waterlogged.
- Check for overfertilization (especially too much nitrogen).
- Ensure your eggplants get 6–8 hours of sunlight daily.
- Add organic matter or balanced compost to improve soil health.
5. Overuse of Nitrogen
Eggplants need nitrogen to grow leaves—but too much of it causes the plant to focus only on foliage and stems, not flowers and fruit.
You may notice large, healthy leaves but a lack of fruit.
Solutions:
Fix It With a Balanced Fertilizer: Choose a fertilizer where the middle number (phosphorus) is higher—like a 5-10-10 blend—to support blooming and fruit growth. Bone meal or rock phosphate can also boost phosphorus naturally.

6. Lack of Sunlight
Eggplants are full-sun plants. If they’re not getting at least 6–8 hours of direct sunlight per day, they’ll struggle to produce fruit even if they’re blooming.
Sunlight can also be reduced if eggplants are too crowded or shaded by nearby plants.
Solutions:
Eggplants are very tender warm-season annuals, and even light frost can harm them. According to the University of Maryland Extension, transplant them only after frost danger has passed, using 8- to 10-week-old seedlings for best results.
- Relocate your eggplants to a sunnier spot.
- Prune back surrounding plants that might be blocking light.
- If you’re growing eggplants in containers, rotate the pots every few days so the entire plant gets balanced sunlight exposure.
7. Improper Spacing and Airflow
Eggplants need space to breathe and grow. Poor airflow can increase disease risk and lower pollination success.
Solutions:
- “Leave at least 18 to 24 inches between plants,” say researchers at the University of Maryland Extension.
- Use tomato cages or stakes to support growth and keep leaves off the ground.
- Avoid overcrowding your beds.

8. Pests and Flower Damage
Certain pests—like flea beetles or aphids—can damage buds before they fully develop or harm the plant enough to prevent fruiting.
Flowers may also be damaged by wind, rain, or even rough handling during hand-pollination.
What to Watch For:
- Small holes in leaves (flea beetles)
- Sticky residue (aphids or whiteflies)
- Curled or chewed flower petals
Solutions:
- Spray neem oil or insecticidal soap if pest levels are high.
- Cover young plants with lightweight fabric or row covers to shield them from pests during the early growth stages.
- Attract helpful insects—like lacewings and ladybugs—that naturally control pests in your garden.

FAQs
Why is my eggplant producing flowers but no fruit?
If your eggplant is blooming but not forming fruit, it’s often due to a breakdown in pollination or environmental stress. High heat, poor airflow, excess nitrogen, or insufficient sunlight can all interrupt the plant’s ability to transition from flower to fruit. Even healthy-looking flowers may fall off if conditions aren’t right for fruit development.
Do I need to pollinate eggplant flowers?
Eggplant flowers contain both male and female parts, so they’re capable of self-pollinating. However, in the absence of natural movement—like wind or insect activity—manual pollination can help. Lightly tapping flowers or using a soft brush to move pollen can improve your chances of a good fruit set, especially in controlled environments like greenhouses or balconies.
How long does it take for eggplant to fruit after flowering?
Once an eggplant flower is successfully pollinated, you can usually expect small fruit to appear within 7 to 14 days. Warmer temperatures and healthy plant growth can speed this up, while stress or poor nutrition may slow things down.
How do I get my eggplant to produce fruit?
To encourage fruiting, focus on creating the right environment: full sun (at least 8 hours), rich well-draining soil, consistent watering, and a balanced fertilizer that supports blooms. If pollinators are scarce, give your plant a hand by gently moving pollen between flower parts to trigger fruit formation.
How to make eggplant bear more fruit?
For higher yields, prune excess foliage to allow light and air to reach developing buds. Choose a fertilizer with more phosphorus than nitrogen to direct the plant’s energy toward producing fruit. Frequent harvesting and maintaining steady moisture levels will also keep the plant productive throughout the season.
