A wild and wooly night for many of us last night. A powerful line of storms moved through the Midwest yesterday afternoon and evening, spawning numerous tornadoes, primarily in Illinois and Indiana. Here in Michigan we were spared the tornadoes but had to cope with a long night of high winds, gusting up to 70 mph along the Lake Michigan lakeshore.

The high winds and heavy rains lead to widespread tree damage and power outages. Dealing with a yard full of damaged trees can be an overwhelming and sickening feeling for homeowners.… Continue reading this article “It was a dark and stormy night”

Hello Charlotte!

I’m sure you haven’t been wondering where I’ve been for the past five months or so, but just in case you have, I’ve been reshuffling my life and relocating. Where am I now? The family and I have moved to Charlotte, North Carolina where I now work at Central Piedmont Community College. Why? Because we wanted to be closer to family, we wanted a warmer climate, and I wanted to spend more time teaching. That said, I had a great time at the University of Minnesota and have only good things to say about my time there.… Continue reading this article “Hello Charlotte!”

My favorite on-line conifer resources

Posted by Bert Cregg

I do a lot of articles and presentations on conifers and while I draw on my personal experience and background as much as possible, invariably I’ll need to consult some references. Here are some resources that may come in handy if you need to develop a presentation or article or just want to know more about conifers.… Continue reading this article “My favorite on-line conifer resources”

Autumn joy…

No, not Sedum…Cardoon! (Cynara cardunculus). Just a TGIF photo. I love autumn’s many shades of brown – kind of underrated with the fixation on blazing foliage.
Now’s the time to collect and save seeds for next year. Though it seems these are trying to escape…

How NOT to do an experiment

Over on Facebook I follow some groups who find provocative topics, and today’s “science fair” post was so over the top that I had to share it here.

Here’s the original post. Now the accompanying text about microwaves is whacky enough on its own (and well worth reading), but my primary interest is with the experiment. This exemplifies why there are basic rules for doing science.

This starts out okay – identical pots, the same type of media (I assume), similar sized plants – but then things go downhill:

1) Replicates are important.… Continue reading this article “How NOT to do an experiment”

For Mulch

Posted by Bert Cregg

Just a quick note up front that today’s post is a little data heavy, so if you’re still adjusting to this weekend’s time change; be advised.

A few weeks back Jim Urban wrote a post entitled ‘Against mulch’ on the Deep Root blog. The principle reasons he cited for his position were: 1) Mulch floats and can clog drains and releases “lots of phosphorus” as it breaks down, and 2) work by Gilman et al.… Continue reading this article “For Mulch”
