Sowing seeds indoors in Sept?

I'd like to know what will happen to flower seeds planted now, rather than spring, indoors on a sunny window sill. I assume they will get going, slow down, and get going again in spring.

I just can't wait until next year! Any thoughts or tips? It's mild here, so I can't imagine the cold will be an issue.

    It's not the heat it's the light levels, that would cause lots of seedlings to probably wilt and die, or become so leggy they will never perform. You could sow a few winter pansies now to plant outside a bit later. Good luck.

  • I have read that ammi majus (one of my favourite plants this year) can be sown directly into the soil Aug/Sept and will produce taller stems and bigger flowers.

    You can get the seeds up indoors of biennials then pot on and keep in the cold greenhouse or cold frame over winter.

  • Ooh I'll do that - thank youimage


  • Ok thanks folks. Well I have sown a few things and will experiment with them on the windowsill and see what happens! I imagine they will get leggy. Will report back in Spring. Don't hold your breath.
