Plug plants

[Dogmatix34]

I bought 12 plug plants from Yougarden- all perennials (salvia, rudbeckia, hollyhock etc.). I have potted them all up and put them in my little Wilko plastic greenhouse. They seem happy enough.
would you plant them out this autumn (in a couple of weeks) or wait until spring?

When did you pot them up? If it was a while ago and they've got good root systems I'd do it this autumn, but if it's only recent, I'd leave them until spring.

About 10 days ago.
thanks for your reply, I’ll continue to monitor them.

I'd definitely give them more time to establish in that case.

I think you will need a safe frost free place during winter.
