Let’s Talk About Starflowers. Why Is Pentas Not More Popular?

It is good to talk about production techniques, performance results and then to see how our friends garden. Diversity of plant material has always been a strength in American garden centers, and we should never run out of plants to get people excited. However, perhaps people are tired of Petunias or Callas or Geraniums, but we will never run out of options to put in front of them. One plant that is often overlooked is Pentas, a fabulous summer crop for late spring sales. These are heat-tolerant plants, and growing them below 65°F in the greenhouse results in significant delay. Fertility should be at least 150ppm nitrogen, but avoid ammonia in the fertilizer. Plants are best grown at a somewhat higher pH than usual, between 6.4 to 6.8. For best presentation, pinch out the center bud. Side flowers will bloom together, and plants will walk off the shelf. Garden centers […]

Backyard Success: Mike McGroarty Educates Aspiring Growers

Mike’s Backyard Nursery sits on a long, narrow, 5-acre property located in Perry, Ohio. There, customers can find a variety of flowering shrubs available, all in 2-quart pots, and all for sale for $5.97 each. Owner Mike McGroarty, a lifelong resident of Perry, says the town has a lot of plant nurseries, including 100 wholesale growers within a 10-mile radius of his house. That doesn’t discourage McGroarty, because he knows that while there are a lot of nurseries in his area, no one else is doing what he is doing. McGroarty has learned about plants — and marketing them to his audience — through decades of experience. He has never hesitated to pass along his knowledge to other growers looking to start their own backyard operations, and has created an entire program to educate aspiring growers. McGroarty Likes To Practice What He Preaches McGroarty’s operation serves as the laboratory for […]

The Butterfly Effect: Insect’s Wings Key To Azalea Pollination

A researcher from North Carolina State University (NC State) has found that in the case of the flame azalea (Rhododendron calendulaceum), all pollinators are not created equal. In fact, due to the flower’s unique reproductive structure, butterflies — and specifically, their wings — are the key to pollination. The flame azalea is commonly found in the Appalachian Mountains, ranging from as far north as New York to Georgia in the south. Like most azaleas, the flowers are large, and have an unusual structure: both the anther (male) and stigma (female) parts are very elongated and separated from one another. NC State biologist Mary Jane Epps was interested in how the azalea’s flower structure affected its pollination. “In order for a plant to reproduce, a pollinator — usually an insect — has to spread the pollen from the anther to the stigma,” Epps says. “In the case of the flame azalea, […]

UMASS Fertilizer Trials Recommend Nature’s Source Organic Plant Food 3-1-1

In a recent online fact-sheet at its Extension website, the UMass Amherst Center for Agriculture, Food and the Environment lists Nature’s Source Organic Plant Food 3-1-1 as “the best liquid organic fertilizer,” according to Dr. Douglas Cox, Stockbridge School of Agriculture. It is called-out by the Extension after a number of years of studying the use of organic fertilizers for growing commercial greenhouse crops. The trials evaluated traditional water soluble and granular slow-release chemical fertilizers. Dr. Cox recommends Nature’s Source Organic Plant Food 3-1-1 as a liquid fertilizer that is readily available, cost effective, OMRI-listed and with good label directions for greenhouses. He also mentions the ease-of-use in how it mixes well with water and can pass fertilizer injectors. “Nature’s Source is currently the best liquid organic fertilizer,” Cox wrote in his article “Organic Fertilizers – Thoughts on Using Liquid Organic Fertilizers for Greenhouse Plants,” “I have seen no foliar chlorosis yet with this fertilizer. Nature’s source is widely available and a great […]

Roots To Re-Entry’s ornamental plant nursery donates plants to local community gardens

Roots To Re-Entry Transforms Lives

An inspired employment initiative takes green-job training behind prison walls to help inmates find jobs in urban agriculture and the landscaping industry upon their release, and along the way, it is changing lives for the better. The Roots To Re-Entry (R2R) job training program, conceived by the Pennsylvania Horticulture Society (PHS) and its partners, does more than teach inmates of the Philadelphia Prison System the skills they need to find meaningful employment; it also teaches them invaluable life skills. The PHS staff leads participants through a 16-week course that includes hands-on projects designed to teach them horticultural skills and provide them with training in landscape maintenance and greenhouse growing. In addition to English and math, the nonprofit Federation of Neighborhood Centers (FNC) offers supplemental courses in health education and employment preparedness. Upon inmates’ release from prison, the FNC assists R2R graduates with the transition to life outside prison walls by […]

4 Reasons Retailers Snub National Brands

Greenhouse Grower’s lead editor, Laura Drotleff, and I got into a debate about why garden retailers, especially independent garden centers, snub marketing efforts from breeders and growers. She was very much on the breeders’ and growers’ side, expressing frustration about how limited retailers’ vision can be on the topic. I’ve reported on the garden retail side of the industry since 1998, about the same length of time Laura has reported on growers. I’ve heard a lot of retailer views on this, so allow me to share the most common reasons why retailers decline free marketing: Costs. While the marketing materials are free, and sometimes advertising, participating in these projects usually requires minimum orders. From a grower’s perspective, the minimum orders are reasonable. If garden stores promote a plant line, they need to have enough supplies to satisfy demand. From a retail perspective, if inventory reports show a plant line can […]

Spread Your Risk Beyond Spring Sales [Opinion]

Growers who participated in Greenhouse Grower’s 2015 Spring Crops Recap Survey said they have had enough of the uncertainty that the weather brings. They said it’s time to build up sales in other seasons like fall so we’re not so dependent on spring. As a couple of wholesale growers, both from the Southeast, very eloquently stated, our industry has mastered squeezing everything we can out of the spring season. And while this year happened to be a very successful one, thanks to the improving economy and elevated consumer confidence, they said, “now is no time to celebrate.” “Spring is still Christmas in the horticulture industry, but we have done such a good job focusing on spring that we have neglected other seasons,” one grower said. “Having so many eggs in the spring basket is dangerous. Fall will never be what spring is, but having a solid second season is in […]
