If your zucchini are turning yellow and rotten this year, it could be for a number of reasons.
Some are self-inflicted, others are not.
From June to the first frosty nights in autumn, zucchini can be harvested in the garden - and usually not too little.
But this year it may not always work out with the large zucchini harvest.
Many plants initially bloom normally and produce fruits, but suddenly they turn yellow and start to rot from the top.
Why is that?
Zucchini in the garden: this can be the reason for rotten fruits
If your zucchini starts to rot in the garden, it doesn't necessarily have to do with making a mistake.
Sometimes it is simply due to the weather: Both
(wet) cold conditions
as well as
excessively high temperatures over 30 degrees and drought
are not good for the plants and can ensure that fruits are repelled, as the Rhineland-Palatinate Garden Academy reports.
Zucchini also dislike it when
day and night temperatures differ too widely,
i.e. when
it is hot during the day and very cool at night.
On cloudy days with little light, zucchini are sometimes insufficiently pollinated by bees, which is also noticeable in the fruits.
That's why a lot of zucchini rot this year
This year there could be more rotten zucchini in home gardens.
For example, because hobby gardeners chose a
partially shaded location
for this season as a result of the hot summer last year
.
The plants usually get by with a little shade, but especially in this summer, when it was often and for a long time cloudy, it is now taking its toll, as the gardening academy explains.

In addition, it was still very cold in May, so hobby gardeners may have given their zucchini too much fertilizer for fear of insufficient nutrients.
With the onset of summer temperatures, heavily fertilized plants could now shed their fruits.
If your zucchini turns yellow and rotten from the top, it could also be due to a calcium deficiency caused by the
extreme weather conditions
.
According to the Rhineland-Palatinate Garden Academy, foliar fertilization with a potassium fertilizer helps here - but only for newly formed fruits.
Care tips for zucchini
In damp and cool weather, the flowers at the end of the fruit do not always fall off by themselves.
You can easily remove these by hand so that no gray mold forms on the dying petals, which in turn spreads to the fruit.
You can also protect the fruits from moisture by placing them on the zucchini leaves.
