keeping cosmos upright

I love Cosmos but how do you keep the young plants from flopping over, do they need special care?

    I find if you grow them really hard when they are young (ie pinch out the growing tips at least 3 times) then you get much sturdier stemmed plants that support themselves much better when they are planted out.  I don't normally sow mine til March either, and that stops them getting too leggy as seedlings.

    If you stay on this forum long enough you can end up sounding like an expertimage

  • keep them where they will get plenty of light and when it comes to mar-apr, plant them deep. i normally use mine as gap fillers and they dont need any supporting.

     

  • Thank you, how big before you make the first pinch?

  • Many thanks Edd.

  • I pinched mine out as soon as soon as I planted out, I bought a cell of them so they weren't that big. Planted them fairly close together (20cms) and they all supported each other.
