Hi Yvonne, cucumbers are extremely prone to stem-rot and if it is that, it will soon keel-over and die. You can lessen the chances of this happening if you make a small mound and plant the cucumber on top, as well as being very careful not to water directly on or near the stem. It's best to err on the dry side with young cucumbers and only water when they really need it. If it does die, remove all parts of the plant including roots to prevent any fungal spores from spreading around the greenhouse.
