Under Siege? Not Really, Just Go For A Walk

I have no trouble with people buying chocolates or wine instead of flowers to celebrate anniversaries, birthdays or peoples’ lives. We should all have choices. However, the other night I felt like I was entering the Republican caucus. I was minding my own business by the television set and became more than a little upset. A website called insteadofflowers.com came on the screen. It provided serene music and wholesome images of busy women doing busy things. It turns out that such busy women enjoy a small token of appreciation, but apparently their enjoyment, according to the voice-over, does not include flowers. This website delivers meals to the house, anything from beef brisket to beef bourguignon. It is a fine website with a good idea. But why pick on us? Why not use “insteadofbaloneysandwiches.com” or “insteadofgrilledcheeseandsoup.com,” “insteadofburgerdoodle.com,” or a dozen other things. When did flowers get to be the whipping boy? […]

Soil System Improves Growing And Sales

My father started our company 45 years ago growing bedding plants, mainly early season production and finished plants for our West Virginia market. It was in the early 1980s that we started growing earlier spring production and shipping materials to southern markets, and by the late 1980s, we also produced pansies for fall. We started using hydrogels when they first came on the market in the early 1990s and found that they really helped with our production by keeping plants healthier for these new markets. Over the years, we’ve grown to be a large young plant producer and have a sizable business growing finished plants in cell packs, 4 1/2-inch pots, 6-inch pots, gallon containers, hanging baskets, multiple sizes of large containers and large baskets for municipal use. Creating The Ideal Soil Mix With our old system, it took several workers to mix pre-made soil with slow-release fertilizers in cement […]

Selecting Fertilizer Rates For Several Spring Bedding Plants

Fertilizing bedding plants can be difficult due to the differing needs of the large variety of plants that we grow. Many operations do not grow enough of any one crop to cater the fertilizer specifically for each crop. Therefore, grouping crops with similar fertilizer requirements and having two to three fertilizer strengths available is a practical way to ensure plants are getting the fertilizer they need. With many new plant varieties on the market, we wanted to conduct a trial at Cornell University to determine best fertilizer rates for several common bedding plant crops. 22 Bedding Plants Studied To Establish Fertilizer Rates Plugs and rooted liners of 22 crops (Table 1) were transplanted into 4-inch (500 mL volume) round pots with a commercial peat/perlite based substrate. The plants were grown in a glass greenhouse at Cornell University during the spring season at a spacing of one plant per square foot. Heating set […]

Greenhouse Grower’s 2015 Operation Of The Year Sheridan Nurseries Raises The Bar

Ontario-based Sheridan Nurseries has long been an innovator in the Canadian market, but during the economic downturn, CEO Karl Stensson says the company decided to take things a step further. “We have survived the Great Depression, two World Wars and many other downturns in the economy,” he says. “During this last recession, our staff set out at being the best at what we do.” The company’s efforts have paid off. Sheridan Nurseries was named Operation of the Year at Greenhouse Grower’s Evening of Excellence, held July 13, at Cultivate’15 in Columbus, Ohio. The company was also awarded for Excellence In Perennials Production, based on its reputation for plant quality and the activities the nursery has led and been a part of, both within its company and in the industry at large. “We are elated and proud of our staff accomplishments,” says CEO Karl Stensson. “Over the last five years, we […]

Delegation Is Key To A Successful Greenhouse Operation

In a packed room at Cultivate’15, speaker Bernie Erven presented key steps growers need to take to improve their delegation skills, the benefits of delegating and the dangers of not learning how to delegate. This is a skill, he says, that everyone needs to learn. “For all of you who are part of a family business, you are choosing not to do things the easy way,” Erven laughed, as he presented a list of ways to know whether or not you’re an effective delegator. The owner of Erven HR Services, LLC, Erven has been working with and observing family businesses for many years. In his presentation, he said, he didn’t share anything that he hasn’t seen first-hand. You might not be a good delegator if you: Tend to be a perfectionist Work more hours than anyone else Lack time to explain clearly and concisely Are often interrupted Enjoy what you used to […]

Customizing Crop Foliage Color With LEDs: Ornamental Crops

Do you find that your purple fountain grass (Pennisetum setaceum ‘Rubrum’) crop is often green to light purple? What if we told you there is a quick solution to enhance and darken the foliage of purple fountain grass or other floriculture crops? In this second article of a four-part series highlighting the multiple uses of high-intensity light-emitting diodes (LEDs), we will discuss our research methodology and findings for enhancing the foliage color of ornamental crops with end-of-production (EOP) supplemental lighting (SL) in the greenhouse. Many ornamental crops that greenhouse and nursery growers produce vary in size, shape and color. These variables are often influenced by the growing environment. For example, leaf color (intensity, distribution or both) of ornamental crops such as purple fountain grass is a key component that often influences the consumer’s perception and ultimately an impulse purchase. The red or purple pigmentation of purple fountain grass leaves is […]

Technology Provides Solutions For Growing In Drought

In April, California Gov. Jerry Brown directed the State Water Resources Control Board to institute reductions in cities and towns across the state with the goal of reducing water usage by 25 percent. The announcement comes following the lowest snowpack ever recorded in the High Sierra. It was the first time in state history that action was taken to implement mandatory water restrictions. In May, the farmers in California’s Sacramento-San Joaquin River Delta agreed to reduce their water use by 25 percent in exchange for assurance that they will not face further curtailment during the June to September growing season. Their proposal was approved by the State Water Resources Control Board. Growers who participate in the program could opt to either reduce water diversions under their riparian rights by 25 percent, or fallow 25 percent of their land. Given these conditions, growers and retailers are in need of methods and […]
