courgette question

I have grown 3 yellow and 3 green courgette plants.

About 2 weeks ago i put one of each into the polytunnel raised bed with plenty of manure and watered well.

The rest are destined for outside after frost risk passed.

Both the ones in pots and the ones in soil have been covered with fleece everynight and it has not gone below 10 degrees.

Why have the ones in the pots continued to grow extremely well, nice  and green. The ones in the soil have sulked and gone a bit yellow?

Multi purpose in pots, would this be better than nice well rotted muck?

Possibly a more even spread of nutrients - and moisture.

Mine often sulk after planting out, as a matter of principle.  I'd give them another couple of weeks.

Thanks everyone, i'll watch them and see what they do. I have plenty anyway.

Blimey, i'm glad i read this post, just put my tray of courgette plants I have grown from seed outside for their first night out!  Will nip outside now and get them back in the greenhouse then.!

Cheers

I think just the act of planting them in a different location will cause a bit of a shock to them.  Different growing medium, different soil temperatures etc.
