Christmas in July at CT Greenhouses

It is Christmas in July for the greenhouse producers who grow poinsettias. In order to have plants that are blooming for December sales, greenhouses start the process early. Poinsettias require months in the greenhouse before they are ready to be purchased and taken home.

Leanne Pundt, one of our Extension educators was scouting the plants for whitefly immatures at one the Connecticut growers last week and took these photos.

New England Greenhouse Floriculture Guide is Available

The 2019-20 edition of the New England Greenhouse Floriculture Guide is now available. Order your copy today!

greenhouse guide cover 2019-2020

New England greenhouse growers have long relied on the New England Greenhouse Floriculture Guide,for its unbiased, detailed information about insect and mite management, disease prevention and management, weed control, and plant growth regulation. The Guide is updated every two years to ensure that it provides up-to-date information about crop management methods and products.

The new edition presents updates on available products and rates, and natural enemies for greenhouse use. We also updated the section of Best Management Practices to minimize the threat to bees and other pollinators.

The Guide is updated every two years by floriculture faculty and staff from the six New England State Universities, and is published by New England Floriculture, Inc.

The 2019-20 edition of the Guide is now available for $40 per copy via the Northeast Greenhouse Conference website (www.negreenhouse.org) or at the UConn CAHNR Store.

The biennial Northeast Greenhouse Conference & Expo is co-sponsored by New England Floriculture, Inc. – a group of grower representatives from the Northeast, augmented by University and Cooperative Extension staff in each state who specialize in greenhouse crops and management.

Put Local On Your Tray (Or Plate) In April

Put Local on Your Tray is a farm-to-school program helping Connecticut schools serve and celebrate regionally grown food. Even if you’re not a school, they have some advice for getting local onto your plate this season.

Days are getting slightly warmer and longer, the breeze is sharp, and the land is both awakened and nourished by fresh spring rain. Farmers are in a busy period of transition, from indoor planning and preparing for the height of summer – to the beginning stages of planting outdoors – making sure everything is ready to go. While there may not be an abundance of produce to choose from this month, there still are some special products to take advantage of for their especially sweet and distinct flavors of spring that they offer. For instance, mixed greens!

Spinach is our suggested local item to look out for – according to our Tray team Farmer Liaison, Shannon. After a long winter, the sugars stored in it’s leaves give it flavor hard to find any other time of year. Seen below, are rows of sweet greens growing at Massaro Community Farm in Woodbridge.

Hydroponics at UConn Extension

hydroponicsHydroponics is a growing area of agriculture that uses mineral nutrient solutions in a soilless system to grow plants. Rosa researches chemistry and water clogging of hydroponics in her greenhouse. “With the CARE project, a set of growers in Connecticut have problems with low quality water clogging systems,” Extension educator Rosa Raudales mentions. “Samples are being collected to see if we can find the parameters causing clogging.” Research being done will determine if the same water can be used without clogging the irrigation system. Growers in Maine, Rhode Island, New York, and Connecticut are being surveyed for the project. Hydroponics usually starts with really clean water, and tying back to her other projects, Rosa hypothesizes that when using reclaimed water; there will be potential clogging challenges which tends to be a costly problem to farmers. Another project researches using bio-controls in hydroponic systems to make water less conducive for pathogens, while increasing beneficial microbes in the water. Rosa is looking at adjustments to nutrients and temperature that will make the water less conducive to pathogens. This joint project with Dr. Wade Elmer at the Connecticut Agricultural Experiment Station is funded through the Connecticut Department of Agriculture Specialty Crop Block Grant Program.

Spanish Sessions at Northeast Greenhouse Conf.

Paper Envelopes in your Mother’s Day Hanging Basket?

What are those paper envelopes in my Mother’s Day hanging baskets?

By Leanne Pundt, UConn Extension Educator

These small paper “envelopes” are slow release “sachets” that contain beneficial predatory mites that attack young thrips larvae.  (Thrips are very small insects (1-2 mm.  long) with narrow bodies and fringed wings. As they feed they can deform flowers, leaves and shoots. Thrips are primarily a greenhouse pest and not a major pest in the home garden.)

More greenhouse growers are using biological controls to manage thrips. These sachets for the hanging baskets consist of bran, whitish food storage mites (that feed upon the bran) that are a food source for the small beneficial predatory mite Neoseilus (Amblyseiuscucumeris commonly referred to as “cucumeris”.  Cucumeris is a beige predatory mite (less than 1 mm. long) that attacks thrips larvae on the leaves and flowers. They pierce the thrips larvae and suck out their contents, killing them. The sachets serve as a breeding system or “nursery” for the beneficial predatory mites which then emerge from the sachets over a 4 to 6 week period.

Slow release sachets are now available as mini-sachets for individual hanging baskets. They are best placed in the plant canopy so they are protected from bright sunlight. If the mini-sachets are placed in bright sunlight, high temperatures and low relative humidity adversely affects the reproduction of the predatory mites. The small mites do not travel far and cannot fly, so a sachet is placed in each hanging basket.

The moral of the story – leave the envelope in your hanging basket, and enjoy the flowers!
