Cucumber Disease Problem

My cucumber plants start to produce flowers and small fruits, then they rot and die. I have had about 6 cucumbers to date but the higher up the plant they are, the more they rot. How do I solve this problem?

 

I have an indoor all female plant. I think it is a Cultivar type and has grown to 8 ft. Is there anything I can do get more out of this plant. I also grow tomatoes in the same greenhouse. I also have a small side-shoot that looks to be growing as well. Advice on feeding (I use Tomarite) would be appreciated as well if possible.

 

"according to the books you are supposed to use a high Nitrogen feed"

Not the books I've got! What you been reading then, eh?!!

 

Hi all,
I have had my cucumber plant growing quite nicly, I've had around 4-5 large cucumbers off but nothing since. What do I do with my plant now? Do I let it continue to grow or are you supposed to cut it down. Do they last just one year or come back year after year?

My leaves have like a white mould ish type look to them.

Any ideas?

 

I have a similar problem with my cucumbers, they start to grow to about the length of a finger then they shrivel up and fall off. Is it just a case of keeping them more humid? I tend to mist in the greenhouse each morning and keep the door closed in this cooler weather.
I have quite a few cucumbers growing, about 2" ones mainly with just a few getting to around 6", they are marketmore, an outdoor type, but i thought they would still be ok in the greenhouse, i left all the flowers on them as i read that they should be left on to pollinate.Ive cut the tips off the side shoots when they have got quite long too, around 5/6 leaves.

 

Let it grow and you should get a few more cucs. They only last one year so cut it down and compost it when it dies back.
The white mould is probably botyrtis and I don't think there are any chemical treatments still available. There has been some research that suggests spraying the leaves with a 10% milk solution helps hold back the fungus (and provide nutrients) but it is not yet conclusive.
Improving ventilation, particularly at night will reduce the chances of catching the virus and/or it spreading.

 

White mould is probably downey mildew on the leaves, usually associated with dry roots late in the season, was easy to control a few years ago with Nimrod T, unfortunately not now available.

Out door varieties need to be pollinated so are actually best grown outside, all female varieties are greehouse only types that need more heat and humidity, and should not be pollinated, should the odd male flower arise.

As to feeding, well I was always under the impression that greenhouse ones needed nitrogen, and ridge (outdoor) needed potash, the outdoor are producing seed, the indoor ones aren't.

All cucumbers abort a certain amount of fruit, if there are some already growing on the vine, its normal for some fruit to rot if there are others still forming lower down.

 

If they are indoor it might just be that they tend to produce a first flush, and then stall, and then resume for the rest of the season. Advice is to remove the first half-dozen, or so, baby fruits to prevent getting the "stall" stage. (I think the plant thinks "I've reproduced" and gives up, or something like that!)

The leaves on mine go pretty manky during the season, and I pretty much ignore it, the plants carry on producing (that's assuming you aren't seeing something more serious)
