Suntory Flowers Releases Its New Grower’s Guide App
Just in time for spring production, Suntory Flowers introduces the Grower’s Guide app – the first greenhouse production app developed by a flower breeder. Designed for iPad tablets, the fully integrated tool provides complete cultural information for the entire Suntory catalog of varieties. With the portable and user-friendly app, growers can sort crops by temperature, light and fertility requirements and view crop times at a glance. In-depth cultural information is provided for each crop. It’s easy to see how many plants per pot are recommended for 4-inch and 6-inch pots and hanging baskets, along with number of weeks to finish. Growers can customize their Grower’s Guide by selecting the varieties they plan to grow and sell. Award ribbons indicate which varieties have been recognized for landscape performance at leading university trials. Once the Grower’s Guide app is downloaded, all of this vital information is available without access to the internet. […]

The Basics & Beyond: Understanding The Differences Between Photoperiodic And Supplemental Lighting
As I talk to growers around the country, I often find that there is confusion between (1) photoperiodic lighting used to create a long day for flower induction of long-day plants and (2) supplemental lighting used to increase the total quantity of photosynthetic light received over the course of the day, which is referred to as daily light integral (DLI) in the greenhouse. For more information on DLI, please visit http://bit.ly/11x79eK To add to the confusion, supplemental lighting is sometimes referred to as photosynthetic or assimilation lighting. In this article, I will attempt to clarify the differences to assist you in selecting the appropriate lighting strategy for your greenhouse crops. Understanding Photoperiodic Lighting The number of hours of light in a 24-hour period (photoperiod) controls flowering of both short-day and long-day crops. It is actually the uninterrupted period of darkness that controls flowering responses. Long-day plants are those that only flower […]

Next Generation Coleus Offers Production Advantages
Coleus has been reinvented so many times over the past 50 years that it is often hard to remember what the plants used to be like. Even the scientific name has been reinvented multiple times in just the last five years. What was once known as Coleus blumei became Solenostemon scutellarioides, which then became Plectranthus scutellarioides, where it rests for now. Originally, coleus was a seed-produced crop used primarily as a houseplant. It was also used as an herbal remedy in tea to help folks sleep. That has all changed in the last 20 years with the infusion of sun-tolerant varieties, late-flowering varieties (to avoid deadheading and extend season of performance), new colors and new forms. In the past 10 years, there has been some very nice breeding for landscape performance and heat tolerance. Over and over, this plant has changed until what we grow today is so superior to […]

Wenke Greenhouses’ Transparent Plug Treatments
As a young plant producer, Wenke Greenhouses is dealing with an issue that’s increasingly important for growers purchasing plugs and liners: How can you make the best decisions for growing a crop if you don’t know exactly what’s been done to those plants before you receive them? President Lisa Ambrosio says the Kalamazoo, Mich., operation is taking two steps to remedy that situation and help customers be more successful with the company’s young plants. Q: What kind of information are you putting together for your plug and liner customers? Ambrosio: We are in the process of creating information sheets this year. We have two versions. One is designed for the grower who is getting the product so they will know more about what we did to the crop in producing it. For example, if we used growth regulators or insecticides on the crop, they will be aware of that and […]

The Ever-Evolving Cuttings Market
Change is a constant among the world’s vegetative cuttings producers. In any given year, the companies on Greenhouse Grower’s Top 10 Cuttings Producers list are added or dropped for many reasons, including consolidation and economics — and 2013 is no exception. Agribio Group’s purchase of Ecke Ranch last year moved it up to the number one position on our list. Both Agribio and The Dümmen Group are owned by holding company DNA Green Group, but operate as separate entities, according to Mark Schermer, general manager of Fides Oro, also a part of DNA Green Group.Dümmen’s volume increased by more than 200 million units, though it remains at No. 5. Cohen Nurseries has a new, state-of-the-art facility in Gderot, Israel, accounting for an additional 3.4 hectares of production space, which moved the independent producer to No. 6. this year from No. 7 in 2012. Florexpo reduced its production slightly in Costa […]
