Waging war on minimum wage hikes

Waging war on minimum wage hikes

A closer look at the impacts of minimum wage hikes on the greenhouse industry in Ontario, British Columbia and beyond.

Pre-made mixed planters have been gaining popularity over the past couple of years. But what makes an attractive mix? Researchers at the University of Guelph and Vineland Research and Innovation Centre saw an opportunity to gain a better understanding of consumer preferences for container plants.
With multiple plant breeders and tech suppliers, Windmill Nursery is a must-see stop on the CAST map.
For the first time in Danziger’s CAST history, their trial garden will feature an area exclusively for retailers. This private space will include new and exclusive varieties, as well as retail displays with full-grown individual plants and container combinations. Here are some highlights:

A proven and innovative tree propagation system is helping growers increase their profitability by producing healthier, more beautiful trees. Launched at the Landscape Ontario Congress, RootSmart is an evidence-based propagation system that promotes an ideal root structure by preventing root girdling at the propagation stage.Root girdling is a well-known and costly problem in the horticulture industry. Research has shown that it starts during propagation and can’t be reversed as a tree matures. Over time, roots circle each other and the trunk, choking and killing the tree.RootSmart prevents girdling in the first stages of root growth – when it counts. Developed in partnership between Vineland Research and Innovation Centre and A.M.A., RootSmart provides growers with a proven solution to improve propagation practices.“Root girdling is a real problem, and growers are starting to see an increased focus on examining root structures in the buying process. We were determined to find a solution that would help growers become better stewards of their products,” says Rick Bradt, Co-owner andManaging Director of A.M.A. “RootSmart is the game-changer our industry has been waiting for, and we are proud to bring it to market in partnership with Vineland Research and Innovation Centre.”As a wall-less, bottomless tray, RootSmart is uniquely designed to encourage lateral root growth without obstruction from growing media. As the roots come into contact with the air outside of the tray, they naturally prune themselves, allowing continued growth in a healthy, lateral direction. By ensuring better quality roots, RootSmart delivers significant benefits for fruit, nut, and ornamental tree growers that result in better products for end consumers:• Reduced mortality rate• Increased transplant success• Improved crop uniformity• Shorter crop cycles• Reduced culls• Reduced labour costs• Healthier, more beautiful trees“RootSmart was co-designed with growers, for growers,” says Dr. Darby McGrath, Research Scientist at Vineland Research and Innovation Centre. “After five years consulting with industry leaders and studying the effects of existing propagation trays, we designed a product that solves the problem of root girdling using proven science. We are thrilled to see it come to life with support and leadership from the A.M.A. team.”A.M.A. holds the exclusive production and marketing licence to RootSmartTM, and is now available to growers across North America.

Aug. 14, 2017, Sarasota, FL – The new dual electric or solar-powered Multiple Use Tow Tractor by ScoringAg can handle a variety of duties in the greenhouse and nursery industries.
Transport within the greenhouse is about to get faster and easier as Berg Hortimotive heads into their last phase of developing a new autonomous harvesting trolley.
In our last article we examined the potential for saving energy by integrating dimmable horticultural LED lighting systems into various feedback-control strategies. This time, we will review background concepts of LED light spectrum and explore how spectral modifications can be leveraged to improve crop production.
What if monitoring temperature controls was automated, and a grain bin itself could warn suppliers of low levels?
Numerous articles have extolled the virtues of modern LED lighting technology for horticultural applications, particularly as a replacement for HPS in greenhouse environments. Various LED technologies have been proven to achieve comparable or better commodity-specific production metrics to HPS in many different greenhouse production scenarios.
When we talk about ‘water management’ in greenhouses, our thoughts typically consider irrigation scheduling, control equipment or maybe simply having enough. At this year’s Lower Mainland Horticulture Improvement Association (LMHIA) Growers Short Course (held simultaneously with the Pacific Agriculture Show in Abbotsford, B.C.), Olaf van Marrewijk of Hagelunie (Leiden, N.L.) gave a different ‘take’.
The horticultural industry is under constant pressure to improve environmental performance while remaining competitive.
Among the many applications of On Robot’s robot grippers, they’re being used to pack herbs at Rosborg Food Holding, one of Denmark’s largest producers of herbs and miniature flowering plants.
It takes a lot of work – and a lot of water — to grow healthy trees and shrubs for Canada’s ornamental plant sector. The industry, which boasts approximately 3,500 nurseries across Canada, uses an estimated 190 million cubic metres of water every year.But new research suggests this is two to three times more water than healthy trees need. And soon a new tool will be available to help nursery managers determine when to turn on–and turn off–the hose.Jared Stoochnoff, a University of Guelph graduate student in the School of Environmental Sciences Controlled Environment Systems Research Facility, is pioneering a new irrigation management strategy designed to reduce water consumption and mitigate the environmental impact of ornamental nursery operations.“Because many nursery irrigation managers lack reliable ways to quantitatively predict a plant’s actual water requirements, they tend to err on the side of caution and overwater,” Stoochnoff says. “This results in unnecessarily high water and fertilizer run-off that negatively impacts local watersheds.”Stoochnoff’s team used high-tech sensor equipment to measure plant water status and quantify crop water stress tolerance thresholds. When they put those irrigation schedules based on actual requirements to the test, they reduced the nursery’s water use by 60 per cent without affecting the total growth or wholesale value of the crop.“It’s not economically feasible to implement the equipment we were using at every nursery in Canada, but by characterizing the relationships between crop water stress levels, weather conditions and species-specific water stress tolerance thresholds, we’re now able to predict optimal irrigation frequency using onsite weather station data,” says Stoochnoff.Stoochnoff wrote a prototype program that used onsite weather station data to predict plant water stress tolerance thresholds. Each time the threshold was reached, the program triggered irrigation and alerted Stoochnoff via text message. He was able to monitor the nursery’s current weather conditions and water use to date, and could even trigger irrigation directly from his cell phone if needed.As a next step, Stoochnoff’s team will develop the program into an app that can be made available to a larger group of nurseries for testing. He says the program will be flexible depending on the nursery’s irrigation preferences.“Once adopted by the nursery sector, this has the potential to conserve millions of litres of water each year and reduce the environmental footprint of ornamental nursery operations,” says Stoochnoff.Financial support was received from the Ontario Ministry of Agriculture, Food and Rural Affairs, Canadian Nursery Landscape Association, Landscape Ontario, and The Gosling Research Institute for Plant Preservation. In-kind contributions of materials, labour and field site access were provided by Connon Nurseries, C.B. Vanderkruk Holdings, ICT International and Root Rescue Environmental.This project was funded by Growing Forward 2, a federal-provincial-territorial initiative. For more, visit AgInnovation Ontario
An Alberta Agriculture and Forestry specialist says commercial greenhouses in Alberta should be able to benefit from some new research into construction materials and greenhouse design. “Greenhouses have traditionally been energy intensive operations, but with increasing scrutiny and slowly shrinking margins, producers need to find ways of trimming costs wherever possible,” says Dustin Morton, commercial horticulture specialist with Alberta Agriculture and Forestry.
November 2017 – Are skyrocketing land prices preventing you from starting your own farm business? Don’t fret, because crops can be grown in old industrial buildings too – legal crops at that.
October 2017 – Preparation for painting my home office/study recently required a serious clearing out, and I undertook a somewhat enforced go-through of my filing cabinet. You know the feeling. (If you don’t, do it sometime, it’s pretty liberating. But be warned, it will take you much longer than you think!) Three drawers packed tight with technical crop information from the late ’80s onwards. (Now you see why it was liberating.)
October 2017 – Lighting research is very exciting these days, with manipulation of LED placement and wavelength both possible. We checked with three leading greenhouse lighting researchers to hear about their newest studies – some ongoing and some recently completed, some new and some building on previous studies.
It seems there is never a dull moment in the greenhouse ornamental industry. From transitions to new crops, new export requirements to novel pest problems (I’m talking about YOU, mealybug!) the industry has seen a lot of change lately. And it’s not over yet.
The disease triangle is a concept used by plant pathologists to explain factors necessary for disease to occur. Disease will only occur when a virulent pathogen is present, the plant is susceptible to the pathogen and the environment is conducive for disease. If one of the three components is absent, then disease will not occur. That is why when we think about preventing plant diseases, we should keep the disease triangle in mind. Ask ourselves, which parameters can we control?
While recently watching a television special on the great women of ancient Egypt, I was reminded that depictions of containerized plants, specifically non-native trees being transported in large containers, can be traced back millennia. By the fifth century, containerized plants were common, and some fast-growing herbaceous species were grown in containers for use in festivals.
One of the most predictable and chronic pests of greenhouse crops is the western flower thrip.
Peat moss is a frequent, major component of potting mixes, but harvest of the material is becoming unsustainable. Not only is peat being removed faster than it can re-form, its harvest and use in potting mix contributes to the release of carbon dioxide into the atmosphere.
December 2017 – Cannabis sativa has been used medically, recreationally and spiritually throughout the world for about five millennia now. In recent times there has been an increasing trend of the public being more accepting towards the use of cannabis as a medical treatment option for various illnesses.
Oct. 11, 2017, Umeå, Sweden – Researchers at Umeå University and Wageningen University have discovered how plants can defend themselves against aphids.
Sept. 28, 2017, St. Albert, Alta. – It’s been a pretty good year for peat harvesting in Canada.
October 2017 – A longtime garden favourite, New Guinea impatiens can be an easy growing option for the greenhouse producer as well, with a few simple tips and techniques. That is true of the newer sun loving varieties like Sun Harmony as well.
October 2017 – This is the last part in a six-part series of articles on thrips (and other pests) integrated pest management, where we provide practical application tips and tricks, information on new technologies and how it all fits within an overall IPM program. Each article is accompanied by a short video demonstrating a technique or principle.
October 2017 – The pepper weevil has become a bigger nightmare for pepper growers in Leamington area. The swarming of pepper weevil in the Leamington area might be a result of the milder winters and more year-round greenhouse production, inter-planting schemes and lack of attention on greenhouse cleaning procedures that enhance the survivorship of pepper weevil. Ignoring just one adult weevil is a reason to take out an entire crop.
September 2017 – Ontario has long been a world leader in the adoption of biocontrols in floriculture crops.
Last December, Long Island Iced Tea Corporation announced that they were looking into how they might utilize blockchain in their business practices. As part of this announcement, they changed their name to “Long Blockchain Corp”. Shares of the company rose 200 per cent following this news.
Local food, a topic that is, and has been, on the mind’s of many, is a growing industry; however the question of transportation of local food is one that has been left behind, until recently, that is. Over the last few years there has been a resurgence of companies focusing on local food distribution, however Foodshed.io differentiates itself by incorporating technology not only to connect producers and consumers but to enhance efficiency, reliability, flexibility and transparency throughout the entire platform. Their tagline reads: reinventing local food distribution.
We are all aware that retailing is changing and changing rapidly. The key to success is to identify where your business fits into the retail model of the future.
Creative growers and retailers are always looking for new and innovative ways to capture consumer attention. This is particularly true in the historically conservative and stoic world of perennials. No longer are retailers simply lining out an A to Z offering of hardy plants, hoping consumers will be equipped with enough knowledge to select the right plant for the right space.
Pure Flavor credits their partnership with IFCO as one of the keys to providing fresh produce to North America year-round.
This year’s article reporting on the 2017 trial season will look at both the favourites of visitors to the trial gardens as well as other unique entries that performed very well in the trials at Vineland (containers only), Guelph (containers and ground beds), Milton (ground beds) and the Royal Botanical Gardens (ground beds).
Does Ukraine have Garden Centres? This question has been asked of me a number of times over the last few weeks. Last winter I was invited to Ukraine to work with garden centres and present a workshop to the industry. This was my first visit to the country and new experience for me.

Leamington – How does a first-generation family-run greenhouse land its branded products in grocery stores across Canada and much of the U.S.? By perfecting its growing process, and adding a little Zing!.Jordan Kniaziew, vice-president of sales and marketing at Leamington-based Orangeline Farms says since his family entered farming in 2000, they’ve focused on finding the best varieties and seed selections for peppers and other crops.Since 2013, the family has been growing, packing and shipping its own products — including award-winning peppers and greenhouse strawberries – under the Zing! Healthy Foods brand. “We’re always looking at growing products that fit the taste profiles we’re after,” says Kniaziew. “In peppers, our core product, we’ve seen there’s room for growth in the category overall by growing peppers for every meal – in fajitas or stir-fry, scrambled eggs and as snacks.”In addition to common red, yellow and orange peppers, Zing! offers packages of “chef samplers” under specific taste profiles such as sweet and hot peppers, as well lunchbox peppers. The company has won multiple awards for its peppers and other products including a Premier’s Award for Agri-Food innovation Excellence for its greenhouse strawberries.Kniaziew says the family’s initial interest in growing food stemmed from his parents’ first careers in health-related fields. Kniaziew’s father is a local optometrist, his mother is a nurse and his brother studied sciences. The Kniaziews continue to value a healthy, active lifestyle and they see farming as an extension of the health care field.But an interest in growing healthy food and a proven track record of growing quality greenhouse peppers didn’t necessarily mean an easy road for Zing!. Kniaziew says when the company began its branding process, it had to build its customer base from scratch.Today, they boast a handful of growing partners and a staff team that reaches 85 at peak season and Kniaziew says the company continues to grow its family of products with a focus on maximizing production while maintaining its brand’s superior quality.“There’s innovation not just in selecting the right variety, but in finding the best way to grow it, pack it, brand it and deliver it to the consumer,” Kniaziew says. “It’s important the consumer gets a full experience, and that the product isn’t being hidden in the back of the grocery store.”This project was funded in part through Growing Forward 2 (GF2), a federal-provincial-territorial initiative.                                                
Veteran Ontario cucumber grower Jan VanderHout is up for any challenge in the greenhouse or farm association boardroom.
Perennials are a modern gardener’s dream – that’s what more and more garden centre customers are realizing.
December 2017 – I’ve been attending the Canadian Greenhouse Conference for 22 years and this year’s edition topped them all.
When it comes to adding energy curtains (sometimes referred to as thermal blankets) to a greenhouse everyone focuses on energy savings. And certainly energy savings should be a major factor in any greenhouse grower’s decision to purchase energy curtains.
June 17, 2017, Mona, UT – In recognition of leading energy saving efforts, Houweling’s Group was among four companies honored recently as part of Utah’s Energy Efficiency Challenge.
March 16, 2017, Simcoe, Ont. – With the Ontario government’s cap and trade program now in effect, many greenhouse growers in the province are quickly discovering the high cost of fighting climate change. To some, that cost appears unsustainably high.
March April 2017 – Spring is a time of hope and renewed energy with longer days of sunshine and warmer weather. It is also a great time to reflect on how energy costs in the past months have impacted your bottom line, and to work with your team to make your greenhouse more cost-effective for the year to come.
March 10, 2017, Guelph, Ont. – Ontario farmers can finally expect some relief with lower electricity bills on the way.
Nov. 25, 2016, Guelph, Ont. – Affordable energy is a serious issue in Ontario. Rural Ontario is the hardest hit by energy inflation with most businesses, residents and farms relying on electricity, propane or heating oil to support their way of life.
Nov. 7, 2016, Guelph, Ont. – The need for natural gas across rural Ontario is a top priority for the Ontario Federation of Agriculture (OFA) and rural municipalities.
November 2016 – Greenhouses provide vegetable and flower growers with the ability to control all the inputs needed to yield healthy, plentiful crops. In a greenhouse, growers can tailor the amount of light, CO2, moisture, heat and cold, and other variables in order to improve both the quality and quantity of their production.
June 2016 – If it’s true that each food unit we consume now takes about 10 units of carbon energy to produce, then perhaps the food system is broken. Surely it does not make sense to use more energy to produce something than we can get back out of it in useful food energy. What options do we have?
June 2016 – In our August edition last year we presented an overview of a few of the new alternative energy projects across the country. This year, we have more exciting news to share, along with some recent updates.
Oct. 1, 2015, Moberly Lake, B.C. – The Saulteau First Nations are replacing a plant nursery’s propane heating with a biomass heating system, with funding support of $150,000 from B.C.’s First Nations Clean Energy Business Fund.
June 23, 2015, Windsor — Greenhouse operators in the Windsor-Essex Region will reduce their electricity costs and expand their production by taking advantage of electricity programs offered by the Independent Electricity System Operator (IESO).
Vancouver, BC – Ashburton Ventures Inc. has recently announced a zeolite efficacy trial in partnership with InnoTech Alberta.
As a grower, one of your worst nightmares is finding out that you have a potential pest in your grow space. The sight of your hard work looking sickly can be very disheartening to say the least.
The 2017 poinsettia season was much better than even the top sales we saw in 2016. This past year marks three years in a row where poinsettia production, sales and consumer satisfaction has improved. Sales were better for the growers in general, but not great for all retailers – depending on the product sizes, packaging, displays and sales timing. And consumer satisfaction depends on which product they ended up with.
Overall, 2017 was a pretty good year for Ontario’s spring flower crops in terms of pests. Insects like western flower thrips were fairly low (no heavy fly-ins like in 2016) and more severe diseases were scarce. Here are some tips for how we can keep 2018 going in the same direction.
Ball Horticultural Company is thrilled to announce a breakthrough years in the making. Through a collaborative effort with KeyGene, both companies are pleased to announce the successful sequencing and assembly of the Impatiens walleriana genome. This first-of-its-kind project creates a highly accurate tool for breeders looking to provide new solutions to the industry in Impatiens.“Genome sequencing and assembly not only provides a more efficient approach to breeding and plant trait identification, but it provides a deeper understanding of our products and their ultimate potential in the marketplace,” says Matt Mouw Chief Technology Officer for Ball Horticultural Company.Over the course of this project, Ball and KeyGene achieved 100x coverage using long read sequencing technology, which has already led their breeding teams to better utilize significant key plant genes, specifically, genes that confer high resistance to Impatiens Downy Mildew (IDM). The disease has severely impacted global sales of I. walleriana since 2008. By utilizing this new resource of high resistance, along with these newly available genomics tools, breeding companies like PanAmerican Seed are closer than ever to producing Impatiens with high resistance to IDM.While PanAmerican Seed has worked to address IDM solutions over the past five years, the impatiens genome project took more than two years to complete. It included disciplines from many areas of the industry, including pathologists, breeders, seed technologists, product development teams, and production.According to Mouw, Ball Horticultural Company has committed to a significant investment in the area of advanced plant technology, with the goal to deliver products, services and solutions to the industry. “This is the first in what will promise to be a pipeline of opportunities in seed and vegetative products that wouldn’t before have been possible.”
The talk of the town at this year’s Canadian Greenhouse Conference was, you guessed it, marijuana. Not shady back-of-hall cloakroom conversations, but openly in the show aisles, on the bus during the tours and over dinner. One of the tour stops was even to a production facility: “… Aphria, the former Leamington flower grower that transformed its flower greenhouses into a state-of-the-art regulated medical marijuana production facility.”1
November 2017 – Here in southwestern Ontario, we have just experienced a wetter than usual summer, with cooler than average temperatures especially at night. The continuously rainy days and nights and the cooler temperatures put the plants in the Sawaya Garden Trials through new Mother Nature stress or benefit tests, depending on the varieties.
November 2017 – It’s difficult to think of a more diverse, interesting and misunderstood category of plants in the horticultural industry than perennials. A colleague once said that “all plants are annuals somewhere and perennials somewhere else.” Although she oversimplified this just a bit, the point was well taken.
Oct. 27, 2017, Smiths Falls,Ont. – Tweed Inc., a wholly-owned subsidiary of Canopy Growth Corporation, and DNA Holding LLC  have renewed and expanded their partnership through to October 2022.
Oct. 11, 2017, Smiths Falls, Ont. – British Columbia will soon be home to a 1.3-million-square-foot greenhouse cannabis operation.
