Crop Culture
Feb. 5, 2016, Frankfurt, Germany – In contrast to animals, plants form new organs throughout their entire life, i.e., roots, branches, flowers and fruits.
Nov. 23, 2015, Raleigh, NC – Christmas cacti are sensitive to low substrate pH conditions, which can lead to phylloclade chlorotic blotches and necrosis.
December 2015 — I have decided to write about the powdery mildews (PM) this month because I found very serious infections earlier this year both on tomatoes and cucumbers. As the name suggests, most growers recognize the symptoms easily by observing white, powdery stuff on the upper surface of leaves. The pictures accompanying this article adequately describe the symptoms.
December 2015 — Research is underway at the University of Guelph to speed up how quickly and efficiently a plant can be reproduced.
November 2015 — Once relegated to a mere light spot in shade gardens, heuchera has become one of the world’s most popular garden plants, establishing itself firmly as a garden classic thanks to a recent resurgence in selection and breeding. The latest efforts have brightened the market with a palette of hues previously unseen in the coral bells world.
August 2015 — Submitting samples for analysis can often be overlooked with the usual day-to-day demands of a greenhouse operation. However, proactive monitoring of greenhouse resources is a far smaller sacrifice than could be required if plant health declines and diagnostic testing is needed to determine the nutritional imbalance, not to mention the loss of a crop.
June 2015 – Ask just about any greenhouse vegetable grower in Canada for their wish list, and “year-round production” would at the top of most pages. Retailers like the idea of a single supplier, and consumers throughout North America are favouring locally grown foods.
April 9, 2015 – Are you having trouble with lantana? Slow growth, little branching, or plants that are too big for their container?
March 27, 2015 – We’ve been seeing more begonias on greenhouse benches over the past few years.
March 16, 2015 – Success with succulents focus of e-GRO webinar 

March 16, 2015 – This Friday’s e-GRO Alert webinar (1 to 2 p.m. EDT) will look at succulents.
Feb. 5, 2016 — The e-GRO Alert “Bedding Plant Troubleshooting iBook” is now available as growers prepare for the upcoming season.
February 2015 – Poinsettia is still the largest seasonal flowering crop, even though overall production numbers have decreased by 30 per cent in recent years. In Canada, the decrease over the past five years has been more like 65 per cent.
February 2015 – I had a chance to participate in two great conferences last fall, one in Saskatoon organized by Saskatchewan Greenhouse Growers Association (SGGA), and the second one here in Edmonton (Green Industry Show and Conference).
Coleus is one the easiest plants for consumers to grow (and so VERY easy in commercial production), they provide season-long colour and sales and are tolerant of a wide variety of conditions, but the new cultivars that are reaching the market are far better than the old-fashioned types.
Nov. 28, 2014, Surrey, B.C. — For some, urban agriculture (U.A.) is nothing more than the latest fashion trend. But is it more than that?
