What's up everyone? Welcome back to the Epic Gardening Podcast. Today I am taking a question from Q mysterious name, but a great question. He or she says

0:11.6

Zucchini's only flower and produce no fruit.

0:15.0

What is going wrong?

0:17.0

Now, many people who grow zucchini's

0:21.0

for the first time are confused and wonder what they did wrong.

0:24.8

They see the flowers and they think that those will develop into beautiful,

0:29.9

delicious zucinies, but they don't. So they wonder, hey, what am I doing wrong? Well, many

0:36.5

zucchini plants produce male and female blossoms. The male blossoms appear first to attract bees, so your zucchini plants might produce blooms for a week or more that don't set fruit.

0:48.5

The male blooms have the pollen necessary to pollinate the female blooms, but they don't produce fruit on their own.

0:56.5

So male blooms, again, those will appear before females and they typically will appear on a long and slender stem.

produce fruit is because the male blooms are not pollinating the female blooms.

1:27.1

So in the natural world outside of gardening where zucchini's grow in the wild, bees visit the male bloom, and then the pollen sticks to their bodies,

1:36.3

then they visit the female bloom, and then inside of that blossom, there is a sticky substance that pulls the pollen off of the bees.

1:45.2

Then that pollen is deposited into the bloom, that fruit swells and begins to grow.

1:50.3

That is the pollination process that we're looking for.

1:53.0

So the simple answer here to answer Q's question is to say that your zucchini plant is not getting

2:00.6

pollinated.

2:01.9

So you need either to increase the amount of bees

2:05.2

in your environment, so you get some natural pollination
