Left my new fruit and veg plants out in garden last night

[Duchessofmuchness]

I bought some plants yesterday at garden centre - tomato, strawberry, courgette, radish and lettuce. And some sweet peas too. (Some of the plants were bought inside garden centre so probably not hardened off at all). Unpacked them into garden from car and then completely forgot to go back and put them inside overnight. I fully intended to harden them off for a week or so.

Temp last night was about 6 degrees. They look ok this morning.

What do you think? Will they be ok and how soon will I know?

All these plants are outside at our garden centre so I imagine they’d be fine?

Thank you. Some were outside (but under cover) but the tomatoes and a few of others were inside.

At this point I suppose I will continue with what I planned and take them in at night and will see how they are next weekend .
