The Garden Professors™

This is the springtime installment of our random, look-behind-the-scenes of the plant world blog post. In this episode we’ll take a look at William Forsyth, a gud Scottish horticulturist.

William Forsyth was born in 1737 in Old Meldrum, Aberdeenshire in northeast Scotland. In 1763 he moved to London to work at Syon Park House for the Earl of Northumberland. After that gig he transferred to the Chelsea Physic Garden and trained as a gardener under Phillip Miller.… Continue reading this article “People and Plants”

You may have heard about these fungi or perhaps not. But if you look carefully on bags of potting mix and on some fertilizers you will see that they are marketed as “essential” to your garden plants.  Claims on mycorrhizal products suggest dramatic growth increases.  These claims like many “snake oil” products can be extreme and are based on science that supposedly bolsters their efficacy.  Mycorrhize are responsible for tremendous growth increased when compared to plants denied access to the fungi. … Continue reading this article “Mycorrhizae! Myco what??”

I started writing for The Garden Professors a little over a year ago. My very first posting was on “The weather where you are.” In that article, I described some simple ways to measure the microclimates around your yard using some simple hand instruments. But many of you are already well past that and have your own weather stations. For those of you who don’t, here are some considerations for adding a weather station to your garden and a shameless plug for CoCoRaHS (Community Collaborative Rain Hail and Snow Network), a citizen science network of rainfall (and snowfall!)… Continue reading this article “Measuring the weather in your garden”

“In the Spring a gardener’s fancy lightly turns to thoughts of…plant shopping!”

If Alfred, Lord Tennyson had been an avid gardener, I am sure he would have included the above line in his poem “Locksley Hall.” I certainly look forward to visiting nurseries and plant centers in the spring to see what new goodies await. But my enthusiasm is tempered with caution – because bad things can lurk in otherwise perfect plants.… Continue reading this article “Shopping for landscape plants – an illustrated cautionary tale”

Water is a precious resource and gardeners are often careless with it. Water rationing is a real thing for many of us and, with continuing and spreading drought, may become a reality for many more. Is it possible to have a beautiful garden while minimizing water use?
It is indeed.
[Disclaimer: This blog post is about ornamental landscapes. While efficient water use is also needed for a production garden, the need to produce food is the priority.]… Continue reading this article “Agua Es La Vida.”

Is it spring yet where you are? How can you tell? Here in the Southeast, we are well along the path to spring, even though the calendar says we are still in winter. I can tell by the daffodils, spring peepers, and migrating birds I see overhead. I know those of you farther north may not be seeing any signs of spring yet, with winter storms still moving through your states and lots of snow on the ground as well as frigid temperatures, but trust me, it is coming!… Continue reading this article “Surfing the “green wave””

Ukraine is all in the news these days as Russian troops are amassed along its borders in Belarus and neighboring Russia. I have some knowledge of Ukraine having visited the Chernobyl nuclear exclusion zone (the “Zone”) four times in 2012, -15, -16 and 2018. I had planned more visits but the global COVID-19 pandemic prevented my return to Ukraine and the Zone. The accident at Chernobyl was the worst nuclear accident in the history of mankind releasing more radio isotopes than the event at Fukashima and had long ranging impact on Ukraine and the then Soviet Union.… Continue reading this article “The Gardens of Chernobyl 30 years after the disaster”

…National Pesticide Safety Month. Let’s review some key points of safe pesticide use. 

Socrates said, “ The beginning of wisdom is the definition of terms”

So let’s define a pesticide.
A simple definition is any substance used to control, deter, incapacitate, kill, or otherwise discourage organisms harmful to plants, animals or humans can be classified as a pesticide. A fuller definition can be found here. Germane to our discussion, herbicides make up 80% of all pesticide use.… Continue reading this article “February is…”

If you have watched the news at all in the last two weeks, you know that there was a huge underwater volcanic eruption near Tonga in the South Pacific Ocean on January 15, 2022, that spewed ash and gases into the atmosphere. It blew with such force that the sound of the eruption was heard in Alaska thousands of miles away and the atmospheric pressure wave it set off has traveled around the earth as many as ten times according to satellite and ground-based sensors.… Continue reading this article “Volcanoes and climate: How will the eruption in Tonga affect our gardens?”
