Hi everyone, I'm new here so I hope I'm posting this in the right place .
This year I'm growing a Cosmos Atrosanguinea for the first time. What I'd like to know Is do you pinch the tips out ( like Dahlias etc. ) ? It's about 8 inches tall and has 7 shoots.
That sounds a good plant so I'd be tempted to leave it. However, if you do pinch it out (it won't harm it), do it fairly soon. It'll flower a few weeks later,but fuller.
Thanks for the reply, I think I'll leave it for now then . I did think that I might have left it a little late.
