Can anyone help? Courgettes are behaving oddly and hoping someone could give some pointers. I've 3 courgette plants in 4 foot square 2ft high bed, a mix of compost and cow manure. Plants grew well, but 2 in particular have gone a bits nuts producing lots and I mean lots of tiny courgettes. The only thing I can describe it as is a head of broccoli (if that makes sense). None of the fruits are maturing fully but we're managing to cut finger sized fruits from the 3rd plant. Has anyone else experienced and rectified this or am I better giving the bed over to something else? Could it be the cow manure being too rich? It's first time I've used it.Thanks to anyone who can offer some advice. I've tried to attach a pic but file is too large (any pointers on reducing size of file would also be appreciated :-\)

It could well be that the cow manure is too strong or fresh. We had that once with tomatoes where the top growth was haywire. They grew out of it. How about removing most of the tiny flowers as soon as you see they are female, as you would with overcrowded apples? Are there plenty of male flowers and bees for pollination? That is a frequent cause of courgettes not growing properly past the initial stage.
I would persevere and see if the plants get through this setback. On the other hand, depending on where you are, there might be time to sow a few more plants to see if they turn out better.

Hi there,
I've not had this problem but it could be a number of things.
-I'd have thought the most likely is some kind of chemical poisoning, perhaps from the cow dung if the cows have grazed on land treated with broadleaf herbicide.
-Could also be a natural mutation - perhaps a dodgy seed batch?
I'd be surprised if it was too strong a nutrient level - courgettes like a lot of muck and if it was too raw, the leaves would have been scorched and the growth stunted.
Tomatoes are a little different in that they often lose their apical dominance - their drive to grow from the top of the plant-and can easily revert from normal vegetative growth to flowering growth and back again.
Not sure any of this is really any help though and for most places it will be rather late for sowing now, baby courgette it is...

Hi and thanks for responding. There's plenty male flower and bees so thinking the pollination isn't the problem. I did pinch out a couple clumps of fruit earlier to see if it gives room for others to develop and might hang fire to see if it makes a difference. I only used the cow manure for the courgette bed so might do some experimenting, plant some beets or lettuce in both manures and see if there's a difference. Hoping chemical poisoning isn't the cause, we've already eaten some of the little blighters! ????

If it is aminopyralid toxicity from the cow manure, you will need to get rid of it, but of course you would want to be sure. Do a search for details.

Thanks again for advice . Think I'll be doing some research.

I think it is much more likely to be related to or associated with the fact that the sex of the flowers produced by the plant is not going very well .
Nature times the female flower to start to open when the make flower starts to produce pollen ( or the other way round .)
Look up pollinating of curbits & IIRC you'll see what I'm on about
BER ...Blossom End Rot .
The flower end of the courgettes & curbits hold a lot of bacteria , cool damp conditions this leads to the ends of one of the sexes going rotten.
Once you have set flowers ,,, those flowers starting to turn to courgettes you can feed the plants with a pint of correctly dilute tomato feet once a week .....watered in & around the main root stem .
We have been laying the low lying courgettes on pieces of clean white plastic to see if we can get over the problem , for we too have only be able to get pencil thick 3 inch long courgettes so far this year .
Come to think of it I'll have a read up of old Percy Throwers gardening encyclopedia book from the early 1960's to see what he recommended .

In Percy's book & D G Hessayan's the vegetable & herb expert it says a common cause of small or few fruits is poor pollination .... too wet too cold ..
So give nature a hand
Fertilize two or three female flowers in one go ( there is a very tiny marrow looking growth behind the flower )
A male flower has the thin stalk without any swelling behind the flower base , It also has some long thin straggly leaves directly at the base of the flower
Simply cut off a male flower on the thin stem & put the head of the male flower that has pollen on it in to the mouths of two or three female flowers giving it a gentle wriggle each time .
It''s best done in mornings that are dry days so turn of the automatic sprinklers if you have them ........ for a few days .
Don't let the ground dry out either .
