Podcast – Better living through chemistry

One of the coolest things about plants is their unlimited ability to manufacture some of the most amazing biochemicals.  This week’s podcast will brief you on some of these phytochemicals in the news – they’re good for you as well as for plants!  We’ll also explore whether natural organic compounds are really all that much safer than synthetic chemicals.  (You can probably already guess the answer to that one.)

Enjoy!

Maybe an early demise is better?

Yesterday I gave a presentation at an Urban Forestry symposium here in Seattle.  One of the sidebar conversations I had came from a urban forester who had (to my mind, anyway) a different way of looking at urban street trees.  I’ve bemoaned for years that our trees die far too young – we plant species that should live for decades or even centuries, only to watch them fail and die in a fraction of that time.  … Continue reading this article “Maybe an early demise is better?”

Something to grate on your nerves

I’ve had an on-going discussion – OK, argument – with a fellow faculty member who does research on social dimensions of forestry, including urban forestry.  She contends that we basically know everything we need to know about growing trees in cities and that the real underlying problems in urban and community forestry these days are social issues.  This, of course, means that funding for urban forestry research, what little there is, should be directed at social sciences.… Continue reading this article “Something to grate on your nerves”

Upon Further Review…Iron Phosphate for Slugs and Snails

I’m not going to sugar coat it – I’ve been too cavalier in recommending iron phosphate for slugs and snails. 

A few days ago Erin Harris put a comment in my post about dandelions asking whether those iron phosphate baits you can buy for slugs might also be toxic to earthworms.  The answer is yes – they might.  And not only that, these iron phosphate baits can also be toxic to other animals such as dogs.… Continue reading this article “Upon Further Review…Iron Phosphate for Slugs and Snails”

Podcast – another chat with Riz!

Those of you who’ve been following the podcasts remember Riz Reyes as one of my recurring guests.  He’s back this week, discussing ways you can shop for plants effectively at the big box stores.  It all fits into the theme “Getting Your Money’s Worth.” You won’t want to miss it!

Are you a “before” or an “after” mulcher?

Planting annual displays is not (at all) my
favorite gardening pastime, but we do some "color" around our events
building and along the garden entrance to make the area pop during our busy
season.

Those of you who install institutional or commercial color beds are familiar with the process  – yank out last season’s annuals/tulips/whatever, smooth out the bed, plant new annuals, then mulch. Or…do you mulch first, then plant?

If the order of events is plant, then mulch, care must be taken not to get it all over the plants.… Continue reading this article “Are you a “before” or an “after” mulcher?”

Answer to Monday quiz

Well, students just finished finals here at MSU so I suppose it’s appropriate we put our faithful GP readers through their own gauntlet of quizzes…

Top marks to Terry for determining the damage on the conifer seedlings was due to incomplete overlap on the sprinklers the grower used for frost protection during our most recent freeze.  Our record-setting March warm up pushed budbreak ahead by about a month in most locations in the state.  Fruit crops (cherries, grapes, blueberries, and peaches) have been devastated but nursery crops and landscape trees came through relative unscathed until the freeze the weekend before last.

Answer to Friday quiz

Lots of good feedback on this one!  Full marks, however, to our retired copyeditor Carolyn who nailed it cold. Maybe you should consider coming out of retirement and helping at the Seattle Times 😉 

Thanks to everyone for contributing!  If you see EPEs in your local newspaper (that’s egregious plant errors), feel free to send them along for inclusion in a Friday posting!

Monday pop quiz time!

I know Linda normally handles quiz duties, but I received a couple of intriguing pictures last week.  Rather than just tell you all what’s going, I thought we’d have a little sport with it.

The photo below was taken last week ago at a container seedling nursery in western Michigan.  These are trays of container-grown spruces.  Most of the seedlings are green and growing but some are tip-damaged – with a specific pattern.  What’s going on and what caused the pattern?… Continue reading this article “Monday pop quiz time!”

A Friday treat for taxonomy buffs

I can’t match Holly’s post for cuteness, so I’ll have to settle for constructive criticism.  Below are photos that appeared in the Seattle Times earlier this week.

 

 

Your mission, should you choose to accept it, is to identify the errors in nomenclature within each caption.  (This may seem insignificantly picky, but scientific names need to be uniformly constructed to avoid confusion.)

Anyway, have fun!  Answers on Monday.
