Hi, yes you do, it encourages more flowers :-)

If you have a lot like I have then it's a bit of a chore but worth doing.

Definitely or you end up a. Covered in seeds which are a b!"£!er to get off and b.Seedlings springing up everywhere and not always where you would like them.

Well, it depends if you like your Geums or not; they have attractive seed heads. I suppose that I do 'dead head' ours as I collect the seeds, but not until they are ripe.
