Zucchini Plant Not Growing Fruit

Your zucchini plant is growing very well and even flowering, but not setting fruit. This is a guide about a zucchini plant not growing fruit.



Here are questions related to Zucchini Plant Not Growing Fruit.

Question: Zucchini Plant Not Producing Fruit

I have a few zucchini plants that are not producing fruit. They all look very healthy, big, tall, and keep extending their territories. All have lots of flowers, but the female flowers wilted before they bloom.

Is it seed problem? soil problem? The seeds were from last year's crop which yielded on average 5 or 6 good size fruits per plant. I use mostly cow manure and compost soil, supplementing with "Miracle Gro" 15-30-15.

There has been plenty of sunshine and they are well watered. Lately I added some cedar mulch to help retain the moisture. Yet nothing seemed to get the female flowers to bloom.

Pollination should be your first consideration. We don't have enough bees anymore to do all the work; I go out first thing in the morning and look over my zukes and other squashes. Oftentimes, a single plant will produce both male and female flowers. Mostly male early on, but the female (fruiting) flowers should come on shortly.

I hand-pollinate by removing the male flower from the stalk, peeling back (every so gently so as to not disturb the pollen) the flower petal part (eat this, its subtle flavor is yummy!) and leaving just the base and the center. Then stop by one or two female flowers and pollinate them by hand. They should go on to produce fruit as long as they are getting enough water.

The flowers should be new that day; older flowers tend to be too far past prime.

Works for me in AZ most every time. Good luck!

Question: Zucchini Blooming But Not Setting Fruit

I have several of zucchini plants this year and they are huge! My problem is that they bloom with flowers and then all of the sudden the flowers close up and then eventually fall off. I do not have any animals getting inside the garden and I have checked for any pests and there are none. I water ever other day usually as long as it's not extremely hot and in that case every day! Can you help me with any suggestions? I have managed to only grow one zucchini so far.

Question: Identifying Male and Female Flowers on Zucchini and Cuke Plants

How do I know the difference between a male and a female zucchini and cucumber plant?

There are three ways to determine which is which.
1. Stems - The male blossom has a long, slender stem, while the female blossom is on a short stem.

2. Blossom Attachpoint - Male blossoms have only a slender stalk directly attached to the stem. The female blossoms have a small bulbous area below the flower. This is actually the ovary which is an unfertilized zucchini.

3. Inside flower - Look inside the blooms. The male blossom has a stamen in the center of the flower. Female does not. The pollen on the stamen pollinates the female plant.

No. It's not too late, it's actually too soon. Now that the flowers are there the bees and butterflies will polinate them. Then the fruit will start to grow. Give it more time.

Question: Zucchini Not Setting Fruit

My zucchini plants look beautiful and have large green leaves. They were grown from seeds (which were planted 1-16-12). There are beautiful large blooms, but no zucchinis yet. What is the problem?

You answered your own question with the word "yet". Just wait, the butterflies and bees will pollinate them, then they will show up. It's too soon.

The first flowers are always male; they are because the pollen will be waiting for the female flowers. Just wait a few days.

Question: Zucchini Plants Stopped Setting Fruit

I'm growing courgettes in green houses. The problem is that my production has stopped after a few weeks even though my plants are strong and have green large leaves. Bees are also working very well. I don't think there is poor pollination. Can you give some suggestions as to what may be the problem?

I live in New Jersey and have a problem with Zucchini plants. The plants are huge and healthy and producing an enormous amount of flowers, but no Zucchini. The flowers fall off and no fruit is produced. I don't see any female flowers forming. What can I do to help the plants produce fruit. I have never experienced this problem before with the Zucchini plants. Please help.

If this is the first flush of flowers on your Zucchini plants, don't worry. What you're seeing is normal. Zucchini plants, like all members of the Cucurbitaceae family of vine crops (melons, cucumbers, squash, etc.) produce male and female flowers on the same plant. During the initial first flush of flower production, usually only one gender of flower (usually the male flowers are first) is produced for the first few weeks. These flowers naturally shed their pollen and drop off. After this initial flush of flowers, a second wave of flowers develops that will contain both male and female blooms. I'm not sure exactly why this is, but some scientists think it's nature's way of "luring" in the bees, sort of giving them time to catch up and discover the flowers. Successful pollination requires proper timing and this first flush of "bait" flowers may be the plant's way of making sure there are bees at the ready when both genders of flower emerge. If the female flowers on your plants (the flowers with the slight swelling below the back of their petals) continue to drop off once both types of flowers are being produced, it's an indicator of pollination problems (the female flowers will abort if not pollinated). Then you may need to consider hand pollinating your plants.

RE: Zucchini Plant Not Producing Fruit

This is a common problem with Zucchini. The flowers need to cross pollinate themselves for the fruit to grow and mature. Sometimes you may even notice the Zucchini growing and rotting at like 4 inches long. Bees are essential to cross pollinating and if there are none around or not enough, you can help the plants along. Take a Q-Tip and rub some of the pollen from one flower and then rub it into the next flower and so on. This will ensure proper pollination and should help produce plenty of Zucchini. (07/12/2006)

RE: Zucchini Plant Not Producing Fruit

I don't think that everyone knows how important bees, the black bumblebee, wasps, and the wood bores are to pollinating fruit trees, vegetables and berries. Some of my neighbors use insecticides and other sprays for their lawns. These are so harmful to the pollinating creatures. My one neighbor had used weed killer on their lawn and we were finding dead robins. I called our local bird watching group and they said that the weed killer poisoned the worms and bugs, and the birds eat these, which kills the birds. Please, everyone, try and use environmentally safe products. (07/13/2006)

I have planted a zucchini and it has started producing a lot of male flowers (a month ago), but it hasn't produced a single female flower. What can I do to encourage my zucchini plant to produce female flowers, too?
