Too early to sow?

We are in the South East and have an unheated greenhouse.  Is it too early to sow Cornflower, Cosmos, Marigiolds and Lychnis coronaria?

    I'd say too early, especially for the cosmos. I've sowed hardy annuals in Autumn but I suspect the temps and light were better then than now

    For many of them too early. I'm sowing cornflower around the first week in March and I'm based in the south. You can try Lychnis Coronaria now but I think it's best to keep them with cool steady temperatures, so if the greenhouse gets too warm, move them outside to a warm wall to keep the surroundings consistent with minimal fluctuation of temperatures.

    March is best, but cosmos are so quick that anytime up to June for a late flowering will do. If you’re too Keen, you may be sorry. You can’t plant them out until April/May, by then they will be very leggy.

    You will be better waiting.

    Makes sense. Just itching to get out and do something.  I’m sure most on the forum feel the same.

    If you're desperate to do something it's a good time of year to take hardwood cuttings image

    I live in the southeast too and last year grew all those you mentioned except the lychnis. Just checked back and I sowed them in heated propagators in an unheated Greenhouse in the middle of March. Sorry I haven’t been able to give you more encouragement!

    See original post

     I used to be like that, very keen to get started but have learnt over the years you can make work for yourself as you will need to do it again, now I look forward to the winter to have a rest in preparation for the many hours I will spend seed sowing, digging beds, etc.  

    I have given up completely sowing any seeds in the autumn, having learned that the are all the same size if not dead, by the following spring and I have the worry of them overwinter.

    take advantage of the rest time, do your planning, sort your seeds, scrounge some, as we do? clean your gH’s Sort out your pots and trays in readiness for sowing later.   Soon you can apply your chicken pellets, any compost you’ve made. Take it easy, you’ll soon be flat out!
