Quick advice needed!

So, I wrote to the supplier of veggie plants (who shall remain nameless) last week as my April delivery still hadn't materialised - fair enough, given the weather - to say we're off on our hols for half term, so please not to send them during half term. We're off tomorrow, and he sent me a dispatch notice, saying they'll arrive today !!! 

Anyway, too late to do anything about it, but can anyone advise what I do with the plants this evening - it needs to be quick (family of 4 still to pack for....) but keeps the plants alive for a week...

Help - desperate and disorganised!!

Considering the strange weather we're all experiencing right now, I'd recommend you keep all the plants indoors for a start with your heating set to come on if temps dip below 63 indoors.

Water everything well, drain, and keep in a poly sheet lined box so they'll stay reasonably moist. You could always stuff crushed dampened newspaper between the pots but not over the plants (could cause mold). I wouldn't put any sort of sheeting over the tops as they'll need to 'breathe'.

Mostly it's brassicas, so hopefully they ought to be ok outside.
The trouble is, they tend to arrive not in pots, but as plug plants, and so are at risk of drying out, I think.

I would say they would need to be potted or they may well not survive, it depends how many and cost to take the risk.

I'll see what I can do - I'll try and fill a few pot with compost and jam them in, just to keep the roots moist.
Thanks!
