Agaves, those bat pollinated, succulent, strong leaved, slow-growing, xeric- and heat-loving Western Hemisphere plants, are literally the heart of the tequila and mezcal industry. As fascinating as the bat pollinator aspect is we’re going to focus on the how agaves are used to produce liquor.

Let’s start with the differences between mezcal and tequila. These include region of origin, plants used and production methods.

We’ll start with regions and plants.

The name “mezcal” comes from the Nahuatl word “mexcalli” which means “oven-cooked agave.”… Continue reading this article “A Toast to Agaves”

In this edition of P&P we’ll be exploring the life of the “Father of Texas Botany”, Ferdinand Jacob Lindheimer.

On May 21, 1801, Herr and Frau Lindheimer of Frankfurt, Germany welcomed little blue-eyed Ferdinand to the family. After schooling at the Frankfurt Gymnasium and a Berlin prep school, Ferdinand spent the next 30 years studying at universities in Bonn, Jena, and Wiesbaden.

In 1833, for political reasons, Ferdinand decided it was best for him to leave Germany.… Continue reading this article “People and Plants”

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?”

I am constantly slaying horticultural snake oil dragons. There is so much misinformation on the web and even within University/Extension publications. In this blog I turn my attention to compost–a subject that is almost universally cherished by gardeners, gardening groups and horticulturists. Unfortunately there are a lot of misnomers about compost.

Plants are composed of cellulose and cellulose is a complicated polymer of glucose molecules. Compost is made from the decomposition of organic matter—usually plant debris.… Continue reading this article “The Yin Yang of Compost”

This time of year, I often get asked for a forecast for the coming growing season. Will we have a drought? Will it be warmer or colder than normal? Will we have any tropical storms in our area? All of these things affect how farm crops (and gardens) will perform over the next few months and how big the yield might be when it comes time to harvest. In this week’s blog, I will look at some of the factors that go into seasonal forecasting and how it all comes down to numbers.… Continue reading this article “Seasonal forecasting: Looking into the crystal ball”

I just returned from one of my self-imposed retreats where I have no cell phone service nor internet. This means I can focus on writing without interruption. One of my projects this year is to publish a scientific critique of permaculture (stay tuned for that late 2023). Part of my process is to read popular permaculture publications and I am focusing on Gaia’s Garden.  Earlier I’ve posted some general critiques of the book (you can find them here, here, here, and here), but until yesterday I had missed a big, fat problem: a section labeled “The Power of Sheet Mulch” (pages 71-75 in the first edition).… Continue reading this article “Deep sheet mulching is “bat-sheet crazy””

I think I have a pruning fixation. I take most opportunities that come along to write about pruning. I have not blogged yet about Spring pruning. It can be a useful way to achieve some pruning objectives. Like all practices it is not necessarily the method or timing of method of choice for all plants. Spring Pruning can have some specific impacts on development of deciduous fruit trees that may help in the home orchard.

Springtime may not be the most obvious time to prune–in fact springtime within the geographic context of this blog requires definition.… Continue reading this article “Spring Pruning”

Last April 30, 2022, I wrote a post about what a third year of La Niña meant for gardens. La Niña, you might remember, is an atmosphere/ocean phenomenon driven by unusually cold water in the Eastern Pacific Ocean (EPO) that shifts the jet streams that steer storm systems around the world. In La Niña winters in North America, it is often linked statistically to colder and wetter than normal conditions in northern parts of the United States and north into Canada and warmer and drier conditions in the southern tier of states in the US.… Continue reading this article “Hasta la vista, La Niña!”
