You can easily tell if zucchini is pollinated by looking at the growth of the fruit in your vegetable garden. Pollinated zucchini squash will stay green and grow longer each day. Unpollinated squash plants will turn yellow at the end, before eventually turning brown and dying. Zucchini squash will not grow to full ripeness without pollination. You can hand pollinate your squash flowers if you keep getting brown fruit. Otherwise, just cut off the fruit after it starts browning. The plant will grow more flowers in the future.

Signs a Zucchini Flower Has Been Pollinated
You can only tell if zucchini flowers have been pollinated by looking at the fruit. When properly pollinated, zucchini squash stays a vivid green color and keeps growing each day. Unpollinated squash starts to turn yellow at first. Then, they will stop growing, turn brown, and get soft to the touch.
- Looking at the zucchini squash is the only way to tell if flowers have been pollinated.
- Pollinated squash remains bright green and grows longer each day.
- Poor pollination turns zucchini yellow before it stops growing and rots on the vine.
- Female flowers get pollinated by the pollen produced by male flowers.
- Bees and other insects transfer the pollen between flowers, but you can also do it by hand.
Only the female zucchini flowers get pollinated. They are the ones with a small squash at the bottom of the blossom. Male flowers grow on a long, thin stem instead. The male flowers produce the pollen that’s transferred to the female flowers. Bees and other insects act as the main beneficial pollinators. You can also pollinate the flowers by hand.
How Do You Hand Pollinate Zucchini Flowers
You hand pollinate zucchini flowers by transferring pollen from the males to the stigma on the females. To do that, you will need a good pair of gloves and a few clean cotton swabs.
- Hand pollinate zucchini flowers by transferring pollen to the stigmas.
- Use a cotton swab to collect the pollen from male flowers.
- Gently rub the pollen directly on the stigma on the female flowers.
- Repeat the pollination process for all the female flowers on the plant.
Start by identifying the male and female flowers on each plant. Then, put on your gloves and use a clean cotton swab to collect pollen from a male flower. Rub the pollen on the stigma at the center of a female flower. Keep track of which flowers you’ve pollinated. Repeat this process for all the female flowers on your zucchini plants.
Can Zucchini Grow Without Pollination?
Zucchini will not grow ripe squash without an abundance of pollen. Instead, the fruit dies on the vine. Since the female flower attaches to the end of each squash, it dies, too.
- Zucchini squash will not reach peak ripeness when there’s a lack of pollinators.
- The unpollinated fruit will die on the vine, and then fall off.
- You can remove the unpollinated fruit to speed up the process.
- Only use clean pruning shears to remove the fruit and flowers.
- The plant will grow more zucchini flowers as the days go on.
The dead fruit and flowers will fall off the plant on their own with time. You can speed up the process by clipping away the unpollinated squash. Always use clean pruning shears and only clip down to the main stem.
Why Does Your Zucchini Plant Have Flowers but No Zucchini?
Zucchini plants need to have their flowers pollinated to produce ripe squash. Without a proper pollen count, only flowers will grow. You will see both male and female flowers appear.
- Zucchini plants with only flowers but no squash are not getting properly pollinated.
- Proper pollination is a must for fruit to grow to their ideal size and fully ripen.
- Pollinators have to transfer pollen from the male flowers to the females.
- Many flowers require up to 12 visits from pollinators before getting fully fertilized.
Pollinators must transfer pollen from the male to the female flowers for the squash to grow. Most flowers need lots of pollen for full fertilization. If that doesn’t happen, then you will end up with poor fruit development.
How to Know if a Zucchini Flower Has Been Pollinated
You can only tell if your zucchini flowers have been pollinated by taking a good long look at the fruit. If the fruit looks yellow instead of vivid green, then the female flowers did not get enough pollen. As a result, the squash will start to turn brown and rot on the vine.
- Female zucchini flowers will only grow fruit if properly pollinated.
- Unpollinated flowers result in discolored fruit that dies on the vine.
- Consider pollinating your zucchini flowers by hand if you often get dead fruit.
- Use cotton swabs to transfer the pollen from the male flowers to the stigma on the females.
- Make pollination a top priority if you want to enjoy big zucchini squash harvests each year.
If your garden lacks active pollinators, consider pollinating your zucchini by hand. You will just need gloves, cotton swabs, and a steady hand. You’ll need to move the pollen from the male flowers to the stigma on the females.
Only with the right pollen count can you have a great harvest of zucchini squash every year. So, monitor your garden carefully and do what it takes to get the fruit growing right. Hand pollination is key, although it’s also wise to do all you can to attract pollinators to your garden.
