'Glenda',

If they are growing in a tray pot them up singly in a three inch pot and
when they fill the pot with roots plant them where you want them to
flower.

In the meantime harden them off i.e. expose them to the outdoor elements
by day, if not too cold, and protect them indoors at night. There is no
need to 'stop' (pinch out) marigolds, just dead head them as necessary.

You could, out of interest, 'stop' one and compare its development with
the rest of the plants.

Emrys Davies.

I'm growing some marigolds from seeds and they're all getting their
second set of leaves on them. I've not got much experience with seeds
but I understand that I should "pinch out" - but what does this mean
exactly and what's the reason behind it? Surely when plants are left
to grow in the wild they're not pinched out and mucked about with.
Any help appreciated.
