Mine are fine at the moment.  Some are in the border soil of my unheated greenhouse inside a bubble wrap inner greenhouse.  I keep them a bit on the dry side.  My greenhouse has a stone central path that is quite thick and has a lot of thermal ballast so maybe this is one thing that is helping.

They are still hanging on.

Not done a lot in 3 weeks, but alive

Like tomato plant, if they get checked by cold weather, it's a struggle to get going again.

So they'll struggle if when the conditions are right DD?
