Sunny days: New tool helps greenhouses make light of winter

Per Aage Lysaa - webBy Lisa McLean for AgInnovation Ontario

Guelph – Each year, Canadian greenhouse growers face a challenge nearly as old as the sun itself: During the darker days of a Canadian winter, nothing grows.

Greenhouse production enters a mandatory hiatus, because there is not enough sunlight to sustain plant growth. Facilities are cleaned out. Plants are replanted.

And when the first harvest of the new season finally arrives, Canadian growers must battle for space on supermarket shelves, where produce from warmer climates has enjoyed its day in the sun.

Now, a systems integration company with facilities in Norway, China and Canada is offering a solution to Canadian greenhouse growers: LED lighting systems that can augment the sun’s rays, even when sunshine is scarce. Continue reading

Identifying healthier trees for greener Ontario highways

Test trees web By Lilian Schaer for AgInnovation Ontario

Niagara Region – Trees and shrubs growing next to busy roads and highways need a special kind of resilience to thrive.

In addition to handling Canada’s cold winter and hot summer climate, they have to be able to survive without after-planting care or irrigation, which means landscapers have to select species very carefully.

To better understand how to create urban plantings that mimic natural systems when it comes to retaining moisture, root shading, and protection from environmental stresses, nursery and landscape experts at Vineland Research and Innovation Centre have designed two experimental test planting sites.

A new website is helping tender fruit growers monitor the cold hardiness of their buds over the winter months and manage possible winter injury.

Growers can register on www.tenderfruitalert.ca to receive free email alerts about potential low temperature situations that can help them make decisions about when they should use tools like frost fans and wind machines to protect against the weather.

The online, automated weather alert system was launched by Ontario Tender Fruit as part of a project funded through Growing Forward 2 so growers can better mitigate climate-induced damage to their orchards and crops. Ontario’s tender fruit crops include peaches, nectarines, cherries, apricots, and plums. Continue reading
