Tracey it depends on which you are growing as to removing male flowers etc. Mine are all in the greenhouse ( their own) I find they like to be moist and watered small amounts frequently but not soaked. They love warmth and a moist atmosphere, leave a can of water, or water the floor, or mist the air. Mine are shaded from direct sunlight. I feed once a week with tomato feed and they are doing great.
Mine are F1 hybrid Telegraph and you don't remove male flowers and a variety of lunchbox sized ones that are all female. They self pollinate, but when I'm in there I sometimes gently shake each plant. Or they get moved as I move leaves to water. They don't like the base of their stem wet, mound up some compost around it and water around the edges of the pot. Hope this helps.
p.s. Have you checked that there isn't a big cucumber hiding on the plant, sometimes they stop producing and small ones die if a monster isn't picked.
