Bounce – it’s not just a fabric softening sheet…

…it’s an Integrated Pest Management tool!

[Note added after-the-fact: this was a  tongue-in-cheek bit of  hyperbole – kind of like “it’s not just a Job, it’s an Adventure.” Did not mean to imply that it actually IS an IPM tool. Very badly worded. Hence the beating I took in the comments. Live and learn.]

Fungus gnats (Bradysia spp.) are a pain in the bottom for commercial greenhouse growers. The adults are more of a nuisance than anything else –it just looks bad when a customer picks up your 6” pot of pansies and a bunch of little black gnats take flight. … Continue reading this article “Bounce – it’s not just a fabric softening sheet…”

Unintended consequences

Unintended consequences.  When doing one thing causes something you didn’t expect. Many unintended consequence stories in biology start with introduced species. I’m going to skip those here.   I’ve been thinking about unintended consequences recently while trying to figure out what to do about my hops. You see, hops have a nasty habit of getting powdery mildew. That’s one reason why you don’t see a whole lot of hops growing outside the relatively arid Yakima Valley (75% of US production).… Continue reading this article “Unintended consequences”

A sustainable resource? Oh, for peat’s sake!

Recently a well-known gardening blog featured a guest posting by a garden writer who made a case for using Canadian sphagnum peat moss as a horticultural amendment.  He defended his preference through “facts” provided by the Canadian Sphagnum Peat Moss Association.
This is kind of like relying on the petroleum industry for the most objective information on the environmental effects of oil spills.  Or the tobacco growers association for data on the effects of smoking on human health. … Continue reading this article “A sustainable resource?

Of Worms and Fertilizers

Today I’m going to write about fertilizers and worms.  The purpose of this post is not to encourage you to use fertilizers.  I agree wholeheartedly with Linda’s post – we don’t need many of the fertilizers which we’re using.  Still, it’s important to know the facts about anything that you’re doing (or not doing) to and for your garden, and to do them (or not do them) for the right reasons.  With that in mind, I’ve been reading about worms and fertilizers for the last few days and wanted to let all of you know the basics of what I’ve been reading, because it is somewhat contrary to what many gardeners believe.… Continue reading this article “Of Worms and Fertilizers”

Fertilizers, crops and landscapes

Last week Jeff wrote about the dangers of using “balanced” fertilizers, especially in reference to phosphorus content.  Comments quickly followed about using fertilizers in many situations – on farms, in container plants, on trees – and so on.  One of the latest comments came from Nick and began “I don’t usually recommend fertilizer for perennials or woody plants to consumers. In most cases they aren’t needed.”  And this leads into today’s topic.

Many of the horticultural practices we use in our gardens and landscapes have, unfortunately, been derived from agricultural crop production. … Continue reading this article “Fertilizers, crops and landscapes”

Potted plants…really potted

A week or so ago my new friend Doug wondered about some gardening advice on the radio: would adding vodka to paperwhite narcissus make the flowers less “floppy?” The explanation he’d heard was that alcohol would burn the roots and reduce stem growth. Then today I received an email newsletter with the same intriguing information. This newsletter referred to a 2006 article that appeared in HortTechnology as the source of this information.

The study by Miller and Finan has generated a lot of interest in the gardening community, especially this time of year as people get ready to force bulbs for indoor blooms.… Continue reading this article “Potted plants…really potted”

When You Gotta Go, Go Green

Here’s a bit of the fact-filled, intrepid reporting we at Garden Professors are pleased to provide.

Just back from a visit/droolfest to Pennsylvania’s "Golden Triangle" of horticulture: Swarthmore’s Scott Arboretum, Chanticleer, and Longwood Gardens. 

At closing time on Saturday, I was wandering through the cavernous halls of the Longwood conservatory, looking for either my travel companion John Greenlee (Mr. American Meadow Garden), or the restroom.  Found one, then followed the signs to the other…

Whoa.… Continue reading this article “When You Gotta Go, Go Green”

Happy Days

Today is such a good day.  Really good.  Almost as good as my wedding day and the birth of my kids good.  Better than the Eagles won the Superbowl good (I’m a big Philadelphia Eagles football fan — Mike Vick and his transgressions aside of course).

Just for today I don’t care much about the arguments for or against organics, natives or even my favorite topic, pesticides.

What’s the news you ask?

Peanuts.  Hot Boiled Peanut.… Continue reading this article “Happy Days”

Why I like science (our visiting professor returns)

I like science.  I see it as a way to figure things out.  It creates a combination of a) things we’re pretty sure of (facts about the shape of DNA, the optimum pH for certain plant species, and theories consistent with such facts, for example) and importantly, b) questions we can ask next.  When research is designed to answer those new questions, the results will either support the things we’re pretty sure of and lead to an expanded understanding and new questions, or they won’t support what we thought we knew and the results will lead to a different understanding and new questions. … Continue reading this article “Why I like science (our visiting professor returns)”

Pigmented Mulch in Paradise

Just back from a quick vacation to Little Cayman island.  Truly a dot on the map – the whole island is about 7 miles long and a mile wide. Only 150 locals and a couple hundred tourists are on island at any one time.  It’s beyond laid back, with few attractions other than the resident iguanas and red-footed boobies (booby jokes abound).

Airport terminal/post office/fire station.

The big draw is diving – LC is the home to Bloody Bay Wall, one of the most famous dives in the Caribbean. … Continue reading this article “Pigmented Mulch in Paradise”
