Garden Diagnostics

A garden plant with symptoms of an insect infestation

I’ve had this funny feeling that something is just not right in my garden. Can’t put my finger on it, but something is amiss. OMG everything is dying! Help! Garden Death is rampant! Well, a bit of hyperbole perhaps, but over the years I have had many calls from gardeners with great concern for plants or their entire garden based on things they perceive to be going on.… Continue reading this article “Garden Diagnostics”

What a third year of La Niña means for gardens

NOAA recently announced that La Niña is favored to continue through summer and fall this year and could last through next spring. This forecast is bound to strike fear in gardeners in the western United States, since La Niña is associated with drought in the western parts of the country which sorely needs more rain. Los Angeles has announced some stringent watering restrictions due to impending water shortages, and that means gardeners will have to be especially careful there to use the water they have wisely.… Continue reading this article “What a third year of La Niña means for gardens”

The plants have eyes! Another foray into B(ad) S(cience).

A week or so ago one of my “friends” sent me a link to a new journal article that claims plants can “see.” (The use of quotes here indicates that plant vision is suspect, as is the friend status of the person who sent the article.) Of course, dissecting the claims in this article became an all-consuming task for the next several hours. And rather than writing off those hours as never to be reclaimed, I decided a blog post would at least set those thoughts down to save other skeptics the time.… Continue reading this article “The plants have eyes!

People and Plants

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 1737-1804

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”

Mycorrhizae! Myco what??

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??”

Measuring the weather in your garden

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”

Shopping for landscape plants – an illustrated cautionary tale

Flower shows, like this one in Philadelphia, get gardeners excited about buying new plants.

“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”

Agua Es La Vida.

No swimming? That’s the last thing we should be concerned about.

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.”

Surfing the “green wave”

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””

The Gardens of Chernobyl 30 years after the disaster

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”
