On Jakes's advice I have sown some hardy annuals outdoors under glass.
They are now a couple of inches high in their seed trays and I'm
wondering when to pot them up. They will obviously slow up when the
weather gets colder but I want to give the roots all the room they need.
What I have are nigella, cornflowers, californian poppies, and night
scented stock. They can probably just about be handled but maybe I
should leave them for a bit?
Any advice appreciated

Mine were started off in 40-cell trays (simply makes potting on a
doddle as I handle the plugs, not the plants) and are now in 9cm pots.
If yours are in "communal" seed trays the usual "large enough to
handle" rule applies though I'd say sooner rather than later so they
have a chance to get over the trauma of repotting before it gets too
cold.

Thanks Jake, I'll give it a whirl and see just how easy they are to
handle. I think a teaspoon might be best

Wow, pricking out night scented stocks is certainly a labour of love.
Never again!
The cornflower roots were 3"-4" long, so well overdue for potting up
but, at the same time, still too delicate to handle. I don't know how
you resolve that problem.
The others were relatively easy but they all look a bit bedraggled at
the moment. I'll keep my fingers crossed.

If they are not to thick I'd have left them in the trays over winter
then taken a knife to them and cut the compost into blocks about 1 inch
square and planted those into pots before planting out a few weeks later.

Disturbing seedlings or even more advanced plants this late, isn't a great idea.
So yes, David I agree with you so long as they are not too thick.
However, I would have prefered to sow hardy annuals in their flowering positions, thinning in Spring.
For the o/p I always prick out seedlings asap, which really means as soon as you can grasp the cotyledons between finger and thumb (on no account touch any other part of the seedling, they're too delicate) - don't wait for true leaves. Loosen the compost so you have little lumps of compost full of seedlings with almost all of their root still intact and gently tease them apart and lower them into pre-dibbed holes and lightly close the holes with 2 fingers. If the compost is well well wetted in advance but not saturated you probably won't need to do much else until the little plants are growing away. This way you get almost no root damage and they hardly know they've been moved. The roots you don't want to damage are the root hairs which you can't see without magnification. These will be stripped off if you just yank the seedlings out - you certainly don't want to feel things snapping as you separate the seedlings. This should be done when conditions are favourable for continued growth. So this advice is mainly for bedding sown in early spring.
I taught this procedure to a young colleague some years ago, when he'd done the first 60 or so trays I asked him how he was getting along. 'Oh OK but I wouldn't want to do this for a living' to which my reply was 'that's just what you are doing!'

Just a quick one to add to my post further down.
Hardy Annuals and other hardy plants are what it says on the label, they do not need mollycoddling and there is no need to use precious covered space for them, in fact for autumn sowing they need to be started hard and kept hard, I'm rather afraid you'll find it difficult now to acclimatise those plants to the great outdoors.
An aside to the question, I've used hardy annuals with some success in part of a border that is full of snowdrops. As the snowdrops were dying down a couple of years ago I scratched round with a rake and emptied a few packets of hardy annuals in there, another scratch round and then left them to it. That year we had a lovely annual border after the snowdrops and I then left them until just before the snowdrops started to show through so they self seeded in autumn and spring. We had a good free show this last summer as well.

According to RHS the above are *almost* hardy annuals i.e. they need
*some* protection over winter.
