When should I move them in pot?

I planted cosmos seeds a few weeks ago. They have grown tall now, but I think their stems look very thin. I've never had cosmos plant before. Should I move them to the pot now or should I wait?
Please help.
Thank you.

    Moon_light I am sorry to say I think you may have started them off too soon.
    They look a bit too stretched, light levels this time of year are not quite high enough.
    You could try to pot them on but they might not make great plants.
    Hope others can say if they can be rescued.
    I think I might try again in March if you have more or spare seeds?

    I know it is hard not to "get going" I am holding back.

    I think you started them too soon and they are getting leggy because they need more light. You could pot them on and see if they survive. If you have them, try some more seeds at the end of February/March.

    I do not start them until April. They can't go out until after the frosts, so April still gives you 2 months to get good strong plants.

  • I made the same mistake last year with cosmos seeds as I started too early. They didn’t grow into strong plants. Ones I sowed directly outside in pots in April did much better (until the slugs got them - my advice is to keep them protected until they are big and strong).

    I agree with Punkdoc ,  sow during April nice strong plants and ready to be planted out at the start of June. Monty Don  sows on the 1st June. 
    I would compost those very leggy ones, they’ll only get worse and you won’t be able to keep then until June.

    Sorry @Moon_light , another one to rain on your parade . It's too early to sow cosmos, although l appreciate how impatient you feel ! 
    When you sow again, which l assume you will, when you come to pot them on, you can put them slightly deeper in the pots than they were in the seed tray.
  • Thank you so much everyone for the help.
     :(  :(  I am feeling really bad for those little seedlings. I'll try shifting them to the pot today.

    Moonlight............we've all made the mistake of planting seeds too early......a learning curve.  Now would be a good time to plant sweet peas if you are too imptient to wait until March or April to plant something.  If you must plant seeds now I would be looking at hardy annuals.........they can withstand some cold and frost.  Cosmos are only half hardy, cold and frost will kill them. 
  • Hello, I came back here just to thank everyone who commented on this post. Those who suggested me to try shifting them to the pot, I did so and I am really thankful for suggesting me to do so :) . Heres why..
