May was certainly a strange month. Last year, as we all went into Lockdown 1.0, the weather was glorious and everyone turned to the barbecue. This year the story was very different, with Spring 2021 being one of the coldest in a century. This had several knock-on effects, not least the fact consumers ditched ice lollies in favour of hot pots (according to one online food supplier). A more serious impact of the delayed summer is that nature has had a slow start this year.
