Cucumber pollination

Question

I have purchased a cucumber plant from Wilko. I have since repotted into a large tub and it is growing excellent. My question is: I have 3 females now with yellow flowers in bloom and one male beginning to form. Do I have to manually pollinate the females? It is called a cucumber variance and is a grafted vegetable. I have read that manually pollinating will make them taste bitter, yet others say it has to be done.

Answer 1

Here are some links on hand pollinating cucumbers.
You may want to add a companion planting nearby they may attract bees.

I found nothing in my research that suggested manually pollinating would cause bitter fruit.
