Thank you to all the gardeners who have answered all the other questions I have asked in the past

Just trim off any parts where the flowers are spent - if that's the whole stem, take that, if its just part, nip that out.

Thank you Bamboo for answering my many questions. I will tend to my stocks, now that the rain has finally stopped !! My bareroot hollyhocks are growing a treat now, and my begonias are beautiful. I will take photos of the begonias now that the flowers are in full bloom and send them to goy soon. It is great to get answers to problems from people who know so much about gardening. I love your garden

"Now that the rain has finally stopped" well, no need to rub it in, Mayamurdo, lol - I'm looking out my window at the playing field opposite which now resembles the Sahara desert... and it STILL hasn't rained, despite the promises of thundery showers overnight, not a drop has fallen.

Bamboo, I hear that you have finally got rain today, hope there is enough to do some good. Up here in Perthshire, we never have much of a problem with drought.
It is sunny today though, and the garden is looking quite good again.

Let me just correct you there, Mayamurdo - here in West London, we've had a faint misting of rain on about 4 occasions from early this morning - not enough to wet a fairy's whistle, frankly. Though I'm reliably informed its falling not 5 miles from us, a bit further out...
