I managed to get a quick look at the container plants yesterday as sometimes you get slugs or snails attack them because they are green and lender for them. Not a slug or snail in sight anywhere. So either they got drowned in that downpour or more likely they have all died due to frostbite and hypothermia.
I bought and I know you can make them one of the fat and seed feeders for the birds as there is not much around for them to eat at the moment, they love the thing. They have already eaten half of it.
Keep warm and safe,
Neil.
