Hardy annuals

Sowed some hardy annuals in the last couple of days, the corncockles are already up, how big do they grow in the during the winter? They already look big and strong, they are in an open cold frame at the moment. Do I need to still pot them on as they get bigger? I'm assuming that their growth will be slow/stop when we get to Winter?

Also sowed some cornflowers but nothing showing yet

    What stage have they got to hollie hock? I'd pot on if things look too big for the pot but I try and avoid pricking out in cold weather. Plants need to grow on well after pricking out or they'll die. 

    But I don't grow hardy annuals in pots, only perennials, so maybe different rules apply to them

    Hi nut, still at the very ealier stages........was collecting some corncockle seeds and noticed that on one plant, all the seeds had  cracked/germinated in the old flower head so thought I'd chuck them in  soil as they have come that far on their own!!

    They've got their first two leaves and they are in smallish cubes aprox 3" x 3" a few to each cube. It's still been  fairly warm here so sounds like I might have to keep an eye on them and only repot if they become pot bound in the next month. I'm thinking that they won't grow that much as we are heading in to winter

    I'm sure they'll slow down soon. If it's amild winter and they don't slow down you'll be OK to pot them on. The down side to potting on is the amount of space they take up when you've done so. 

    I haven't put any of my germinated seeds inside the frame yet, I don't want them moving too fast.

    Thanks nut, they are in the coldframe at the moment and hadn't thought about them growing too quickly........if it stays dry might move them out of thereimage

    Good idea, they get a bit leggy in the low light of winter if they come on too fast.

    Thanks nut, makes sense..... similar things happen when I've sowed stuff in doors early, they have the warmth but not enough light.  Will be shifting them outsideimage

    Hi hollie hock. I start haedy annuals in September in modules in a cold greenhouse. Most of them are up although very small. Usually they stop growing at the end of October, but by march the individual modules are ready to plant out.

    I've seen the needle and the damage done
    A little part of it in everyone

    Thanks punkdoc, not really sown hardy annuals at this time of year beforeimage

  • Hi hollie hock, like you this is the first time I have planted hardies for early spring flowering. I sprinkled cornflower and california poppies seeds in two, 2foot deep containers. They are about a foot high now and looks like have slowed the growing. They will be in a cold greenhouse until the spring to protect them from strong winds and snow compaction.

    I've got loads of annuals and perennials germinating in the garden over the last couple of weeks. Some of them must be from last year's seeds or even came in when I spread my compost. I see them as a store for extra plants next year. They're much too close together to leave as they are.

    I realise that a well run compost heap would have killed off the seeds. I have no illusions about my compost heap, the weeds etc break down and I use it.
