Costa Farms Trial Garden Update: 2015 Late-Season Top-Performing Plants

The Costa Farms team announced its late-season top performers in the 2015 Season Premier Trial Garden in Miami, Fla. Its research and development team has been working to grow and evaluate hundreds of varieties and have published their findings here. The plants you’ll find in the link have thrived in Miami’s late-spring conditions. Every spring, the research and development team trials 500 varieties of annuals, perennials and tropical plants from plant breeders around the world. All of the varieties were tested in the 2-acre trial garden. Varieties are assessed for abundance of bloom, crop uniformity and overall performance, which includes factors such as clean foliage, little to no pest damage and the plants’ overall habits and appearances. About 70 varieties scored as top performers during the evaluation period, which lasted from week five to week 19. Transplanting into the trial garden occurred at week 51, and plants were grown in 6-inch pots to finished […]

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 […]

BASF’s Sultan Miticide Receives California Registration

BASF Sultan miticide recently received registration in California, giving ornamental growers a new rapid, targeted mode of action for mite control. Sultan miticide, with active ingredient cyflumetofen, offers ornamental growers targeted knockdown of all life stages of tetranychid mites, with long residual control. It has practically no toxicity to beneficial insects, including predatory mites and pollinators. Sultan miticide offers a new mode of action to combat cross-resistance with other commercial miticides, and is compatible with integrated pest management programs (IPM). “The long-awaited California registration of Sultan miticide is exciting news. Greenhouse, nursery and landscape professionals in the state now have a new class of chemistry that gives them fast control over all life stages of plant-damaging mite populations,” says Joe Lara, senior product manager for BASF. “Sultan miticide now provides California growers with a much needed new first choice for miticide resistance management programs that won’t disrupt populations of beneficial […]

2015 Spring Crops Report: Rain Soaks Spring Sales

Rain, rain and more rain. That was the story this spring for the large majority of growers across the U.S. And where it wasn’t too wet, it was too dry. Drought conditions cut sales in the West and Southwest. But it wasn’t all bad. Eighty-nine percent of respondents to Greenhouse Grower’s 2015 Spring Crops Survey declared the season a success, despite its challenges. They said beautiful weather in April and excited consumers who were ready to spend got the season going early, but then cool temps and rainy weekends throughout May and June caused confusion over when and how much to plant. Of the 189 respondents to Greenhouse Grower’s 2015 Spring Recap Survey, 53 percent identified themselves as grower-retailers, 34 percent were wholesale growers and 13 percent said they were young plant growers. Most responses came from the Midwest (27 percent), Northeast (18 percent) and Southeast (16 percent), but also […]
