My zucchini plants are not producing any female blossoms - hence no squash. They have been blooming for about 3-4 weeks. I have yellow summer squash plants near them and it took about 3 weeks, but there are now a few yellow squash appearing.

Could something be wrong with the zucchini seeds? Is there something I can do to get the zucchini to produce some female blossoms? I started to use miracle grow on them but nothing so far.

Be careful and do not use too much Miracle Grow. Excessive nitrogen could make for lovely large plants and few, if any, flowers.

Usually there is nothing to do but simply wait till the female blossoms appear.

I find that my plant doesn't make female blossoms if it doesn't feel strong enough to support the fruit. A good multi nutrient fertilizer could help without overdosing on just nitrogen. Potassium (potash) is a good one for getting more fruits. You could pick up a soil test kit to see if the ph and nutrient levels are good. They also take a lot of water to make fruits, but they don't like soggy feet, so when I added the drip irrigation they really took off.

Good luck!

I just read in a book that the male blossoms start first, so there is pollen available for the female blossoms. So I expect your female blossoms will still bloom. Do not remove the male blossoms though - unless you are planning to cross pollinate.

Yes, the male blossoms appear first. Sometimes a long time before those female flowers appear.

Not sure where you are, but Aug is a bit late for most squash to start. Mine are usually dying by now- from different things where I live.

Welcome to NGA, @GardenerSuz !

I agree with Kat -- it would be helpful to know where you are located. (My gardening season is nearly over, unfortunately... Rolling my eyes. )

If you are in the far south, and your weather has been quite hot, that could be inhibiting the formation of squash. And, as Rita said, be careful not to give too much nitrogen fertilizer to the plants.

I doubt there is anything wrong with the zucchini seeds -- but some varieties are definitely more productive than others. Smiling

You could try to 'stress' the plants just a little bit by cutting back on the amount of water you're giving them. Maybe water every second day instead of every day? Don't let them wilt completely, but if the leaves sag a tiny bit in the afternoon sun that won't hurt anything. Plants will hurry up and make seeds (which are inside the squash in this case) if they think they're going to die soon.

Once the female flowers start to appear, gradually increase the water again so that your squash will size up. Once they're in production they should keep producing female flowers.
