Hi everyone

I have lots of annual and half hardy annuals seedlings growing happily in my
greenhouse, but have no idea if I should pinch out the tips or not!

I've cosmos, larkspur, clarkia, antirrhinums, sunflowers and lots of others.
Not sure which ones, or if all, should be pinched and at what stage in their
growth.

Please help, I've always worried over this!
Grateful thanks.
