I have some climbing beans in my polytunnel. Something, during the night, is
systematically biting through the stems near to the ground. Nothing else is
being touched.

My main suspects are a couple of hedgehogs that have recently appeared but I
thought that they mainly eat slugs, snails and insects.

Does anyone know if hedgehogs are likely to do this? If not, has anyone any
other ideas, please?

Regards

Howard Neil
