In 2017 I attended a log hive making workshop, led by Jonathan Powell of the Natural Beekeeping Trust. It inspired me to build my own log hive in our orchard at home in Truro, Cornwall. It remained empty for 2 years until finally in June 2020 a swarm of bees took up residence.
I was fortunate to witness the swarm arrive. It is one of nature's most wonderful occurrences. It made every minute of the long wait worthwhile. They will now be left to their own devices to live as nature intended.
