Post Rotting cucumbers

I have some very healthy looking cucumber plants, however, a growing number of the small young cucumbers seem to be starting to go brown/shrivel up from the blossom end. When this happens I cut them off. I am loosing quite a few cucumbers this way.
More annoying though is that some of the large mature cucumbers that are almost ready for picking now also appear to be turning soft/watery/grey from the blossom end, ie rotting. When picked the bad bit can be cut off, but they are clearly not going to store even for a few days.
Does anyone have any ideas?
Thanks

Cucumbers and many other fruits can waste away from the blossom end for a variety of reasons. For small, developing fruit the most likely cause is calcium deficiency. To fix this, cultivate some lime into the earth around the plant, but don't go too deep or you might damage the roots.

Other causes - and this may be why the mature fruit are getting it, too - are prolonged wet soil conditions (UK summer?), several days of hot temperatures (less likely, at least where I live!) and over fertilization. This last one is tricky, as the plants look great (as yours apparently do) but they're growing so fast they can't get enough calcium to the fruit.

I'd try removing the mature cukes as it may help kick the plant into production again, adding a little lime and holding back on nitrogen for a couple of weeks. And, hope for better weather... let us know how things go!

Good advice - makes a lot of sense.
Will give it a try and report back.
Thanks!
