One of the most annoying weeds in garden and landscape beds is horsetail (Equisetum spp.), a genus native throughout North America and most of the rest of the world.

We are again in the midst of excessive heat events in many parts of the United States. Records were broken for the highest temperatures ever recorded just a few days ago. This is also a time when the days are at their very longest, so high temperatures have large impacts on plants in landscapes.

Over the last month, I have seen many stories related to smoke from Canadian wildfires drifting down into the eastern United States, causing muted sunsets as well as terrible air quality.

I saw an article describing an atmospheric phenomenon called the “pneumonia front” this week and it made me start thinking about local kinds of wind and their names. No matter where you live, in the United States or elsewhere in the world, you have wind patterns that are related to your local geography. These winds can affect gardens, especially if they are persistent over time, but I enjoy hearing about the different names for wind too.… Continue reading this article “Who has seen the wind?”
