Zucchini blossom issue

Post  littlebear on Fri Jun 15, 2012 11:56 am

Question....what could be causing the blossoms to fall off after a day or two? The plant is more than healthy and tons of blossoms, but they all fall off a day or two after they bloom.....Any thoughts would be appreciated!

Go out and look closely at the blooms. If they are just on a stem, no baby zucchini, then they are male blooms and perfectly natural. If a baby zucchini is right behind the bloom, then it's a female. If the bloom, with a baby on it falls off in a couple days, then it wasn't fertilized. If the females keep falling off, you may have to try fertilizing by hand yourself.

How do you hand fertilize zucchinis?

Use a paintbrsh and swipe the inside of a male flower then swipe it into the female flower, voila! Good luck with your zukes!

I did it yesterday using a stick. Hope it worked.

What you are looking for is the yellow sticky stuff that is not unlike the centre of your avatar picture.
That bug is getting the stuff all over his feet and will carry it to somewhere else.

not sure if a stick would gather the yellow stuff, I use QTIPS.....
I think it is normal for the males to come out first for awhile and when the plant is doing well the females come out

Yeah, the stick got yellow on the tip from the male before I touched the female with it. I'm just wondering if it was enuff. But I guess bees feet are pretty small. Laughing

How do you know if it doesn't take? Does the baby zuch fall off or something?

The baby will fall off/rot if it doesn't work. Some folks take the male flower, pull off the petals and take the male flower bloom around and stick to each of the female flowers.

I like that idea. Tool-less. Very Happy

I notice on my watermelon, cantaloupe, honeydew, cukes and zucchini I have a ratio of 15 males flowers to every female flower. Is there a way to improve the ratio?

I think the ratio does improve as time goes on, but, you don't want to mess with Mother Nature!Rolling Eyes

I hope so... Didn't know if temperature, whatever, a lack of talking to, a lack of listening to or some other element I haven't thought of affected the ratio.

Each plant can nourish only so many fruits. Even pollinated fruit can drop off is too many get started. That's one reason for harvesting as soon as the fruit is ready. It encourages the plant to produce another.

By chance do you know if there can also be an issue with pollinating fruit if the plant is too crowded? I have some squash crammed in a corner, and the foliage is very thick. I've noticed that flowers drop off without even opening up. This plant is next to another plant that isn't crammed in a corner, gets more sunlight and air in the middle, and is producing.

The pollen has to be able to reach the female plant so I would hand-pollinate. Take a male flower (no bulb at the end), remove the petals and brush the stamens over the female flowers. If Mother Nature can't manage it, you'll have to do it.

Thanks Bea. I've done that if they open, but around the center of the hill where things are so thick it seems like the majority of the flowers don't open, and eventually just fall off. I didn't know if it could be too dark or crowded for the flowers to open. Hindsight, I should've thinned the hill...or better yet not crammed the hill in a corner!

I've had the same problem with them shrivelling up before the flower can even open.

Could a lack of fertilization be causing this



A lot of my spaghetti squash seem to be doing this, and I'm not sure if it's blossom end-rot or lack of fertilization? This is a brand new female (near enough) quite small (maybe an inch long, two at the most) and the plant definitely is producing fruit now, the following picture is a squash about two hands high.

Blossom end rot is common in tomatoes, but rare with squash. What you see is not enough pollen delivered to the female flower i.e. - usually that means not enough bee visits, or not enough viable pollen available. If no pollen is delivered, the female blossom will drop off, with no growth of the ovary. If some pollen is delivered, growth may start, then the fruit aborts (rot on the blossom end goes along with the abortion). A little more pollen, and the fruit may develop, but be misshappen. Finally, if almost all seeds are fertilized (two grains of pollen needed per seed), the fruit will develop into quality fruit.

Here is an amusing video I found with John Kohler about hand pollinating pumpkins and squashes. What a Face
