Over the years I’ve gotten a lot of questions about how to compost.  I’m not a composting expert, and don’t want to pass myself off as one, but I do understand the basics and I like to think of myself as a proponent of composting.  Having said that, there is a composting practice which I’m asked about frequently that I never know quite how to answer.  Should you put meat into your compost?… Continue reading this article “Meat in Compost?”

I’ve been teaching plant physiology or related courses for a long, long time, and one of the tenets is that woody plants don’t heal.  In contrast to animal tissues, when trees and shrubs are wounded the damaged tissues are permanently destroyed.  Wounds are compartmentalized and covered with wound wood.  Arborists are fond of saying "plants seal, not heal."

That’s all fine and good for woody plant parts, but what about grafts?  Since grafting reconnects cambial and phloem tissues, is this "healing?" And… Continue reading this article “Do plants heal?”

‘Tis the season for all things Christmas, including the annual hysterical reports of the dangers of real Christmas trees.  Along with heartwarming reports of Thanksgiving feasts at the local homeless shelter and live remotes of frenzied Black Friday shoppers, footage of Christmas trees going up in flames seems to be a staple of every network affiliate in the country.  In fact, in some cases the intrepid reporter will go to great lengths to insure that the Tannenbaum ignites the obligatory conflagration http://www.youtube.com/watch?v=P9dNS5WPncU… Continue reading this article “I’m burnin’, I’m burnin’, I’m burnin’ for you”

So far a mild fall has lingered here in mid-Michigan.  With temps in the mid-50’s I was able make much more headway on my fall clean-up than usual.  Typically we get enough early snows or cold-damp November gales that I don’t get to the last of the leaves and frosted hostas until spring.  Leaves are especially challenging here at Daisy Hill farm.  We have about dozen hardwood trees, mainly oaks and hickories, that drop a sizable load of leaves each fall.… Continue reading this article “People let me tell you ’bout my best friend…”

Back in 2006, when I first started garden writing, I was invited to give a talk in Michigan.  It was really exciting to get this kind of invitation so early in my writing career and I was thrilled to have the opportunity to talk to an audience that wasn’t composed primarily of students or academics. 

Looking back at those talks…well…they weren’t particularly good.  Sure, there was good information, but I wasn’t particularly comfortable giving talks at that stage and so I’m not sure I got my information across nearly as well as I should have.… Continue reading this article “Jeff Ball”

“Stealing an idea from one source is plagiarism; stealing from many sources is research.”  This quote has been attributed to so many people I won’t bother trying to list them here.  But the point is a lot of what we do as professors is spend our time digging into the literature to look for substantiating or conflicting evidence for the ideas were interested in testing.  As a grad student back in the 1980’s, a time-honored tradition was to spend the afternoon at the library combing the stacks for journal articles, loading volume after volume onto a cart and then schlepping off the library copy center.… Continue reading this article “Looking for answers”

Yesterday I happened to see a garden calendar encouraging people to pick up their leaves so that they don’t pollute streams and lakes by encouraging algae to grow.  This was a good idea, I thought, but then I started to wonder whether leaves on the lawn might not be a better idea?  After all, the reason that leaves cause algal growth in water is because of the nutrients they have.  And if they have nutrients couldn’t those be used for fertilizer instead of the regular fertilizers which we use? … Continue reading this article “Leaves for Lawn Fertilizer”

As an Extension Specialist working with nursery and landscape issues, I’m frequently called upon to troubleshoot problems with trees and shrubs in various settings.  Sometimes it’s residential or commercial landscapes, sometimes nurseries, sometimes Christmas trees.  So naturally I was intrigued when the most recent issue of American Nurseryman featured a cover story on diagnosing nutrient deficiencies in plants.  The article was written by Dr. Gary Gao, Extension specialist with Ohio State University.  The article http://www.amerinursery.com/article-7428.aspx is good and does a good job on covering the basics. … Continue reading this article “Diagnosing plant problems”

OK, the results are in for our reader poll to design a landscape tree transplant study here at MSU next spring.  And the winner is…er, I mean, winners are: Root ball manipulation and Fertilization at the time of planting.  Root ball manipulation drew 74.3% of the responses, Fertilization was chosen by 63% (voters could chose more than one favorite topic).  All other proposed topics were under 40% (Mycorrhizae – 37%, Crown reduction- 31%, Cambistat – 11.4%, Bioplex – 11.4%).… Continue reading this article “The people have spoken…”

(Note:  I’ll be doing another blog posting later today.  Just want to be sure I get this out.)

I’m writing a new book on plant physiology for gardeners – a book that explains how plants work and why they sometimes do weird and unexpected things. I’d like to hear what kind of “how” or “why” questions you’d like to see answered in this type of book.  Please add your comments to this post, or send them to me directly.… Continue reading this article “Reader input wanted for new book”
