The damage doesn't seem too bad anyway, we lost quite a few green tomatoes and one of the sweet peppers (which is starting to turn red as well!) has split but asides from that they don't seem to be too bad which is lucky. They've had a few days to recouperate back in the fireplace but I think we'll need to pluck up the courage to put them back out on the windowsill soon or otherwise they'll start growing in that crazy way like they did before in the fireplace.
There was some damage to the chilli plant in the trough on the kitchen windowsill which didn't tumble in to the garden too and the plant snapped right in half so has had to be chopped right back unfortunately. Fingers crossed the worst of the weather is now behind us!
