Karen Pretorius asks:
My husband removed a swarm of bees from a roof. To our surprise, the honey was green. What can cause it?
Dave answers:
I have to boldly admit that I have never seen green honey in my entire life.
After a thorough search, I found that this phenomenon has been noticed elsewhere, and the sources of nectar indicated are kiwi blossoms, certain thistles, feedlots where bees feed and even sweets (M & Ms).
Do any of these sources occur near the home?
