Cucumber stem rot ?
One of my cucumber plants has rot - I think. The plant is about 5 foot high (in the greenhouse) and has been priducing fruit for several weeks now. I noticed yesterday that where one of the leaves meets the main stem, the stem is rotting and white - this is about 3 feet from the ground. The area affected is about an inch in length. I have removed the leaf. Is there anything else I can do ? Cut off the top of the plant ? Leave it ? Will the other plants get affected too. Although yesterday was lovely and warm in there, today it is only 14c
