Earlier this spring, I posted an article about seasonal climate forecasting and noted that we expected to see the development of an El Niño after three years of La Niña conditions ended in March 2023. And sure enough, an El Niño was declared in August 2023 and has been strengthening ever since. It has a 71% chance of becoming a strong event by December or January before starting to weaken, as they usually do in spring or early summer.… Continue reading this article “What a strong El Niño means for winter weather and our gardens”

Electroculture – rediscovered science or same old CRAP?
I’ve been doing horticulture myth-busting for almost 25 years now – and what I’ve learned is that myths are zombies. Not only do myths not stay dead, but new zombie myths are also continually created. One of the newest bright-n-shiny distractions is electroculture. It’s EVERYWHERE.
What is electroculture, you might ask? Well, Jaccard (1939) described it as “the stimulation of growth in plants by means of electricity passed into the atmosphere surrounding them or into the soil in which they are growing.”… Continue reading this article “Electroculture – rediscovered science or same old CRAP?”
Plant Disease Primer-Part 2: Fungus Among Us
In my last post, I talked about the factors leading to the development of plant diseases and some common signs and symptoms of fungal, bacterial, and viral diseases. In this installment of the series, I’m going to talk about some of the most common fungal plant diseases with some suggestions for treatment and prevention. This by no means will be an exhaustive list of diseases (there are so many!), but I hope to cover some of the most common ones that we see come into the extension office for diagnosis.… Continue reading this article “Plant Disease Primer-Part 2: Fungus Among Us”
The Fascinating Phenomenon of Fasciation
You may have seen it on the odd flower or plant here and there or you may be intentionally growing plants that show this unique and uncommon phenomenon. Fasciation (not fascination- though it certainly is pretty fascinating) is a malformation or abnormal pattern of growth in the apical meristem (growing tip) of plants. The apical meristem is undifferentiated tissue that triggers the growth of new cells (which extends roots and shoots, and gives rise to stems, leaves, and reproductive structures).… Continue reading this article “The Fascinating Phenomenon of Fasciation”
Recognizing bad science by honing your B(ad) S(cience) detector

December 2022
Last week there was much ballyhooing over a new article on the benefits of native plants in supporting insect populations. I’ve posted on the fallacy of native plant superiority before, pointing out that landscape biodiversity not plant provenance, is most important for supporting all types of beneficial wildlife. Despite robust, published evidence to the contrary, more people and governing bodies believe that native plants are the magic bullet for urban landscapes.… Continue reading this article “Recognizing bad science by honing your B(ad) S(cience) detector”
