If they came from Lidl, they were probably in plastic bags, and even if not, have been instore or inside for a while. You will need to harden them off before leaving out all the time - do this by leaving them out for a couple of hours in the middle of the day initially, increasing the time you leave them out until, after a week to ten days, they're out all night.

Our local Lidl looks after its plants by a system of benign neglect! Do as Bamboo suggest but give the pots and compost a good soaking.

Ok will do, thanks for the advice both :)
