Meeting Irrigation Mandates

Every year, Carroll Brothers Nursery, Clearwater Fla., uses 18 million gallons of water to irrigate its 10 acres using overhead irrigation. The pricetag on that much water per year has jumped from $4,500 to $18,000 between 1991 and 2007, so owner Richard Carroll has been looking for ways to reduce cost. The goal when the gardenia grower first started searching for water alternatives was a second water source–one that would pump and clean water or one that would collect rainwater. “Either way, it was too expensive for a nurseryman to handle,” Carroll says. “Knowing I couldn’t touch either of those, I was looking for a way to save water.” Drought and water restrictions can cause a grower to rethink irrigation, but so can research. Looking for an irrigation method that would follow BMP practices, as well as provide consistent irrigation, Carroll Brothers did research comparing drip and overhead irrigation and […]

Svensson Now Shades With White

Need to keep your plants from overheating? Ludvig Svensson has a solution.  Svensson has developed an external screen called OLS White, which reflects light and heat away from plants unlike black shades. OLS White is made with highly reflective white films and does not retain heat during the night. Instead, it provides daytime shade to cool greenhouse temperatures. OLS White also has an open structure that allows air and moisture to pass through easily, and it can be manufactured in 30-percent, 40-percent or 50-percent shading.  “OLS White is a great choice for growers simply looking to shade crops and avoid greenhouse overheating,” says Kurt Parbst, president of Svensson’s North and South American subsidiary. “It’s a powerful tool that contributes to a superior growing environment.”  For more information on OLS White or Svensson, go to www.svenssonamericas.com.

The Liquid Crystaled Greenhouse

The Cleveland Botanical Garden has teamed with Kent State University’s Liquid Crystal Institute in an attempt to examine how greenhouse plants grow under sunlight that passes through liquid crystal windows.  The idea, highlighted in a recent edition of the (Cleveland) Plain Dealer, spawned from the botanical garden’s desire to reduce the cost of energy. If results of the experiment are positive enough, a second experiment will be conducted to determine whether ultraviolet and infrared waves can be modified enough to, perhaps, shorten the time it takes plants to grow.  And that’s where cost-saving enters play. If liquid crystals prove more beneficial in growing plants, greenhouse owners can use them instead of shade cloths to control the amount of sunlight entering their structures.  Liquid crystals aren’t common in greenhouse coverings. They’re usually found in television screens and wristwatches, but that didn’t stop Cleveland Botanical Garden from pursuing this experiment and considering […]

Grower Solution: Diesel-Heated Trucks

Blooming potted plant grower Jim Dickerson of Dickerson’s Greenhouse in Gobles, Mich., has found a cost effective way to add reliable heat to one of his trucks. While reefer units with both refrigeration and heat can cost between $15,000 and $20,000, the Proheat X45 auxiliary heater manufactured by Teleflex Power Systems is a more affordable option and fits nicely with winter deliveries. Dickerson’s delivers live plants to about 700 stores and warehouses over a wide area, from Michigan west into the Dakotas and Nebraska, using a 24-foot insulated dry van truck. The company’s delivery fleet also includes a truck with the reefer unit that can be set to keep plants at a constant temperature when outside temperatures plummet below freezing. Dickerson just finished shipping its signature crop, poinsettias, and is getting ready to ship winter and spring bulb crops—Easter lilies, tulips and hyacinths. Since he began using the Proheat X45 […]

Al’s Loses Roof In Wind Storm

The Statesman Journal in Salem, Ore., reported this weekend that a heavy storm ripped the roof off a greenhouse at Al’s Garden Center and damaged several other structures on the property. According to the article, the garden center’s owner Jack Bigej said the roofs on the 82 greenhouses on the property are built to withstand at least 65 mph winds. Fortunately, none of the damaged structures housed poinsettias. Damage to the poinsettia crop would have been a hard hit to the business, Bigej said in the article. The National Weather Service is working to determine if a tornado touched down in the area. In addition to the production facility in Hubbard, Ore., near Woodburn, Al’s has retail locations in Portland’s suburbs Sherwood and Gresham. Al’s Garden Center happens to be our October cover story.

New Production Management Software

SBI Nursery Software in Portland, Ore., has introduced a new module that provides complete production management. Users begin by laying out a production plan by copying plans from previous years and comparing them to sales history, lost sales and inventory dumps. The user lays out how much of an item they want saleable on a specific finish date and then plans how to grow it by setting up the recipe. The system then automates purchasing of materials for produciton, which inclludes plant material and other inputs. The final functionality lets the user manage production with work orders being sent out to propagate, transplant and execute critical tasks. The greatest challenge whle developing this package has been to keep the user interface simple and efficient, says SBI partner Aaron Allison, who has worked in the green industry for 15 years. SBI has worked with several key customers during development, allowing the […]
