How do courgette fruits rot?
Q How do courgette fruits rot? A The fruits start to develop normally and then, when still quite small, start to discolour and rot at the flower end. The rot then spreads back along the fruit towards the stem. This invariably starts when the petals of the fading flower start to deteriorate and the rot then spreads into the fruit.
Why are my courgettes not growing?
Poor early-summer weather, with a prolonged cold spell, and few insects results in poor pollination. This means courgettes fail to develop, and they quickly rot on the plant. However, this is only a temporary problem, and once the weather starts to improve, so then will the crop.

Why are my zucchini rotting before maturing?
On zucchini and other summer squash, the blossom end of the fruit begins to rot and within a short time the entire fruit has rotted. Blossom-end rot is caused by a lack of calcium in the developing fruit. In most cases, there is no need to apply calcium to the soil.
Can you overwater zucchini?
Overwatering. All plants need water to survive, and zucchinis are no exception. However, zucchinis do not need very much water to grow and thrive. If you overwater your zucchinis, the drowned roots will become stunted and won't be able to properly support the plant.
Why are my zucchini turning yellow and rotting?
Zucchini Turning Yellow And Rotting Blossom End Rot It is caused by a lack of calcium in the fruit and the reasons are not always due to soil deficiency. Calcium holds the cell walls of plants together and calcium deficiency results in stunted growth, misshapened leaves and yellow, rotting fruit.
Should you cut off male courgette flowers?
The answer is to eat the male flowers (dip in batter and deep fry) until the female ones appear. If the weather is cool, hand pollinate. Remove the petals around the male flower to expose the anther, then dab on to the female: one male will pollinate several female flowers.
What's wrong with my courgettes?
Courgettes, marrows, pumpkins and squashes can be affected by a number of viruses including Cucumber mosaic virus causing yellow mottling, distorted and stunted growth. There is no remedy but to discard the affected plant. Resistant cultivars are available.
How often should I water courgettes?
In dry conditions, the plant suffers, soon wilts and produces significantly fewer flowers and fruit. Regular watering is therefore extremely important for courgettes. Depending on the weather, water once or twice a week; in midsummer you usually need to water more often.

What happens if you leave a courgette on the plant?
Left on the plant, the attached end continues to grow normally (thick, dark green) whilst the flower end of the courgette withers and, if left, rots away. This has been the case for several years now and affects all courgette varieties I've grown.
How long are courgettes?
Here's an example of the courgettes I grow. Should have placed a ruler beside them - they are both around 4" to 5" long. The top one had been growing for longer than the bottom one. I know little about pollination but I would have thought if the courgettes had remained unpollinated then they wouldn't grow to this size.
Do courgettes grow at the end of the plant?
My courgettes look more developed than the one shown in the linked photo. They don't grow properly at the blossom end - staying thin and turning soft, eventually rotting if left on the plant, yet they continue to grow at the attached end into a chunky, dark green vegetable, more than 1" diameter. So, half grown as would be expected yet half stunted/wilted and, eventually, rotten.
Why are my courgettes rotting?
However, given that some of your courgettes are growing normally, and those that are rotting are very small, I think the problem is almost certainly caused by inadequate pollination: No fruit, or fruit rotting when very small: This is a physiological problem, caused by the growing conditions, not a pest or disease.
Why are my plants not producing fruit?
No fruit, or fruit rotting when very small: This is a physiological problem, caused by the growing conditions, not a pest or disease. It is a problem when the weather in early summer is cool and this causes inadequate pollination. Remedy: This is usually a temporary problem, and once the weather starts to improve, so will pollination. You can try to hand-pollinate plants yourself by removing a male flower (male flowers don’t have a swelling at their base) and brushing the central parts against the centre of a female flower (female flowers have a swelling at the base – this is the beginning of the fruit). But this is a bit of a hassle, and normally the plant will correct this problem itself.
Why does my cucurbit have a BER?
This could be Blossom End Rot (BER) to which most of the cucurbit family are susceptible. It is caused by a calcium deficiency - see my answer here.
Does the weather affect blossom end rot?
Really, though, the weather seemed to correlate rather strongly with blossom end rot, this year. It was very, very hot, and dry. When it cooled, the plants didn't have as many problems.
Does calcium help with blossom end rot?
Calcium may be implicated in blossom end rot (but that doesn't mean the soil is deficient). Here's a link where Carolyn Male (a well-known tomato expert) tells us all about blossom end rot and how most people don't need to add extra calcium to their soil.
Why do my fruit trees have blossom end rot?
We suspect a few of our growers out there may struggle with blossom end rot this season due to the dry weather that we’ve had lately. Once the fruit is affected, there’s no going back, but you can prevent other fruits from the same plant from being affected.
What does blossom end rot mean?
Blossom end rot is recognisable by the very end of the squash or courgette turning brown/black and rotting as it grows. They basically get a soggy bottom. Mary Berry wouldn’t be impressed.
Is blossom end rot contagious?
The good news is that blossom end rot is not a contagious disease so if one courgette on a plant gets it, then it doesn’t mean that the other ones will. Just try to keep your plants well watered so that the soil is consistently moist and the new fruits should be ok.
Flower and fruit problems
Vigorous plants such as courgettes, marrows, pumpkins and squashes can make huge amounts of leafy growth but this doesn’t always equate to good flowering or fruiting. There may be a number of reasons for this:
Lack of female flowers
Note – female flowers can be identified by the swelling of the immature fruit at the base of the flower.
Lack of male flowers
High temperatures during periods of hot weather or in a poorly-ventilated greenhouse can result in a lack of male flowers. This problem is most common in late summer and autumn.
Fruit set and development problems
Cucurbits, with the exception of glasshouse ‘all female’ cucumber cultivars, produce separate male and female flowers that require pollination to set fruit (note: older glasshouse cucumber cultivars produce male and female flowers but if pollination occurs the resulting fruits are bitter so this must be prevented by removing the male flowers).
Bitter tasting fruit
The bitter taste of some fruit is caused by an over-production of plant defence chemicals called ‘cucurbitacins’. This is mainly a problem in courgettes and summer squash and is caused primarily by a mutation within the plant. The problem is more likely when plants are grown from saved seeds, where inadvertent cross-pollination may have occurred.
Fungal diseases
Cucurbits are prone to powdery mildew. Typically, this causes a white dusty coating on the leaves, stems and flowers, especially later in the season as the weather gets warmer and drier.
Virus problems
Courgettes, marrows, pumpkins and squashes can be affected by a number of viruses including Cucumber mosaic virus causing yellow mottling, distorted and stunted growth. There is no remedy but to discard the affected plant. Resistant cultivars are available.

How to help zucchini plants recover from rot?
Although there's no cure for rot, zucchini plants suffering from blossom-end rot can usually recover if you provide consistent irrigation so the soil doesn't dry out. Remove all infected fruits so they don't become targets for other diseases, so new fruits can develop normally.
Can crown rot kill zucchini?
Unlike blossom-end rot, which only affects the fruit, crown rot can kill the entire plant. It occurs in overly wet soil that causes the roots to suffocate and makes them susceptible to fungal problems. Plants rarely recover once they begin to rot, but you can prevent it from occurring on your other zucchini plants.
