I'm very much a novice, but I'll try to help, as my Geums (totally tangerine) came up great early in this their 2nd year.
I bought 2 of them as plants in (7") pots last year and planted them together. They did well in their first year with good amount of flowers. Like one of the previous posts, I pulled out the stalks from the base when they went brown.
At the end of summer, I cut them back to the newer, fresher leaves (about 18" high) and they stayed green all through winter.
This year, all I did was add some compost around the base in early spring with some feeding along the way (tomato feed later on). I had masses of flowers from early spring until mid summer.
However, I have had nothing late summer. So i have cut them back again now.
They are in a raised bed against a fence, West facing with full sun most of the day.
I've read that theythrive in clay soil and being in London ours is very heavy and reckon this is why they did so well (at least early on)
However, I reckon i wasn't brave enough to cut them back earlier to encourage a 2nd bloom and tried to eek out what I could when I saw a few buds left on longer stalks.
not sure ifbthis helps, but just a bit of personal experience from a complete novice.
