Saving your ash

My earlier post regarding plans to replace the monoculture of ash trees at the Gateway Arch Monument in St. Louis, MO with a monoculture of Lindens prompted a question about options for treating ash trees for emerald ash borer.  This is a complex topic so I wanted make sure I had time and space to respond completely.

 

First, the best and most current source of information regarding treatments for EAB is the Multi-state bulletin “Insecticide Options for Protecting Ash Trees from Emerald Ash Borer” which is available as a full-color .pdf… Continue reading this article “Saving your ash”

Friday puzzle unrolled

I knew this one was pretty easy, but I have my reasons (below).  Gold stars to KB, Jim, John, and Dave for correctly identifying rolls of sod (and they do seem thin, Peter):

Yes, sod.  I dislike instant lawns; they never look good for very long, at least in my part of the country.  And getting rid of sod (as we have in our landscape) is a nightmare with that *%&$^ plastic mesh in which the grass is embedded. … Continue reading this article “Friday puzzle unrolled”

Balanced fertilizers are usually out of balance

I’m in the midst of grading papers for my nursery management class, and something that I’m running across is an incredible number of papers where the students are recommending balanced fertilizers.  Why are they doing that?  Or maybe an even better question is, what is a balanced fertilizer?  A balanced fertilizer is a fertilizer which has three numbers which are about the same, like a 10-10-10.  The problem with balanced fertilizers is that they are much higher in phosphorus than what most plants need — at least in relation to the amount of nitrogen and potassium which plants need. … Continue reading this article “Balanced fertilizers are usually out of balance”

Snow falling on cedars…not always a good thing

Seattle had its first snowfall last week – a mere 3-6″ – and the city shut down.  (Yes, those of you in the snowier parts of the midwest and east can laugh…but we’ve got hills.  That’s the main problem.)  It was unusally cold, so the snow that fell was the light, fluffy kind that I remember from our Buffalo years.

Every year someone writes to ask whether they should remove the snow from their trees and shrubs. … Continue reading this article “Snow falling on cedars…not always a good thing”

It’s Poinsettia Time…

Love ’em or hate ’em, poinsettias are the number two potted flowering plant produced and sold in the U.S., only (very recently) surpassed by orchids. Especially amazing when you consider the five-week market window.  Commercial growers go at poinsettia (“points”) production usually one of two ways:  1) smaller pot, high volume, low margin for mass markets; or 2) larger pot, florist-quality, unusual varieties, for independent garden centers, florists, and other specialty retailers.  If you shopped any big box store this past weekend (bless your heart), you saw rolling racks of “doorbuster” deals such a 4.5″ points priced $1.25 or even less. … Continue reading this article “It’s Poinsettia Time…”

Maybe common sense isn’t so common after all

I noted in my Sept. 22, 2009 post on the threat posed to ash trees in the Midwest by the emerald ash borer (EAB), and included photos of the famous grove of 500 ash trees surrounding the Gateway Arch in St. Louis.  I was in St. Louis that summer for the ASHS meeting and saw that the National Park Service was planting trees from a variety of species around the monument.  I assumed at the time that the Park Service was preparing for the eventual loss of the ashes to EAB.

The decline of Extension and the increased need for science-based information

I hate to be the downer this week, given Bert and Holly’s inspired posts, but reality continues to hit – or bite.  The budget crises in Washington state continues to gut higher education, and one of the hardest hit areas at WSU is Extension.  Land-grant institutions have a federal mandate to provide Extension services, and this sets WSU and similar universities apart from other state schools.  Unfortunately, Extension generates relatively little in terms of outside grants and contracts. … Continue reading this article “The decline of Extension and the increased need for science-based information”
