Depends on pollination now Daz , if the plants are outdoors the bees will do it for you , if indoors or unsure about bee activity brush the tip of your finger along the opening of the flowers.Very lightly , just touch one and then another.Some people use a fine artists paintbrush , your fingertip works just as well.
It reminded me of a story that took place in Glasgows Vodka bar , amazing variety of Vodkas , chocolate vodka , irn bru vodka , liqurice all sort vodka , every flavour you could imagine.One night a friend from work and i were going and our boss guy invites himself,he was a right twat , so after 3 or 4 vodkas we are getting into it and the boss guy goes to the toilet.We had all been slamming winter warmers which was a vodka that tasted just like christmas..lovely.
So he comes back from the loo and we raise our glasses for another slammer...forgetting to mention to the twat we had ordered him the chilli vodka and the warm fuzzy winter warmers for ourselfs..ahhaahhaaa i never seen a fat guy make it to the toilet so fast in all my days.
