I have

(A)cucumber plants
(B) tomato plants
(C) Chilli Plants

Do any of these need to be self fertilised when grown in the greenhouse. I have what looks like small cucumbers with a flower at the end. These cucumbers are getting bigger and so i assume they do not need any fertilization. I cut off the male flowers fairly soon after they appeared.

The tomato plants have lots of yellow flowers on them but have been there for a number of weeks without any change. Do they need self fertilized some how or will they transform into tomatoes without any assistance?

My chilli plant is just beginning to produce flowers. Will i need to do anything?
