Eat your veggies! (But not the arsenic, or the chromium, or the lead…)

The last few years have been a perfect storm for the resurgence of home vegetable (and fruit) gardens.  Grapevines are trellised along sidewalks, herbs replace the grass in parking strips, and tiny gardens of carrots and lettuce are shoehorned into any available spot.  It’s all good  – but we need to be particularly careful about … Continue reading Eat your veggies!

Health care reform (of trees)

Nothing is more frustrating to a gardener than watching a newly installed tree or shrub slowly die.  In performing “post mortem” analyses on failed landscape plantings, I’ve identified four common errors that can be easily avoided: inadequate root preparation improper soil preparation planting below grade inadequate aftercare This blog entry will be dedicated to the first … Continue reading Health care reform (of trees)

I *heart* My NRG Pro Transplanter

[Disclaimer: I do not endorse any particular product over another, nor do I receive ANY compensation (darn it), free stuff, etc. from any companies, whether recommending or dissing their product.]  Seeing Linda’s favorite mulch fork prompted this post – scroll on down past the Great Root Debate (rowr)!  I remember first laying eyes on this … Continue reading I *heart* My NRG Pro Transplanter

Another look at TreeGators

Following up on Linda’s earlier comments about potential problems with TreeGators, my summer interns and I did a random spot check of about 150 TreeGators currently in use on the MSU campus.  As background, MSU Landscape Services plants about 1,200 trees and shrubs each year.  All newly-planted trees which are not on an automatic irrigation … Continue reading Another look at TreeGators

Bare Root Trees

For the past 11 years I’ve been running a nursery at the University of Minnesota called the TRE (for Teaching, Research, and Extension) nursery where we research all kinds of fun stuff like Dutch elm disease, the dangers of mulching, and what happens when you plant a tree too deeply.  One of the most interesting … Continue reading Bare Root Trees

A Brief Discussion on the Wisdom of Barberry as Median Plant

We never know who to blame (or, rarely, thank) for roadside or median plantings. State D.O.T.? Local municipality? Subcontractor to either of the previous? A few years ago, this appeared in the median of the Highway 460 bypass – the main road leading to Virginia Tech: I am somehow reminded of Sideshow Bob from The … Continue reading A Brief Discussion on the Wisdom of Barberry as Median Plant

Bad roots and deceptive marketing

I guess today’s blog should be entitled “The Cranky Garden Professor.”   Really, I’m not always cranky, and when I am I go outside to do something constructive in my garden.  Last weekend I finally tackled a 5-gallon container of lavender that I’d bought several weeks ago.  I had intended to wait until fall to transplant … Continue reading Bad roots and deceptive marketing

Evaluating ‘Scientific’ Claims

Whenever I give talks to landscapers or gardening groups some of the most common questions that come up deal with various products promoted to provide ‘miracle’ results in the garden.  These are usually various soil amendments; fertilizer additives, bio-stimulants, mycorrhizae, and the like.  My initial reaction to these inquiries is, “What does your current basic … Continue reading Evaluating ‘Scientific’ Claims

Long term problems with Tree Gators?

So, Bert, you (and others) have done research on Tree Gator-type products and found them useful in providing water to newly planted trees and shrubs.  For those of you that haven’t seen supplemental irrigation products, they are heavy-duty plastic bags that zip up to create a sleeve around tree trunks and drip water from their … Continue reading Long term problems with Tree Gators?
