for the first time I have grown Wall Flowers from seed. They are now 8/10 inches high. when I pant them in flowering position, should I pick out the tops and trim the roots?

personally I wouldn't do any thing to the roots and probably not pinch out the growing tips. I find they branch out naturally.
