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.

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

envelopes in baskets

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!

Spraying Nematodes

Michael's Greenhouse

Watch the video that shows a grower (Michael’s Greenhouse in Cheshire CT ) http://www.michaelsgreenhouses.com/ applying the insect killing beneficial nematodes are applied thru their automatic watering system onto their hanging baskets on a cloudy day.
The nematodes are in the bucket you see and then they use the fertilizer injector (with the screens removed) to apply the nematodes. This is commonly done on the bench or floor crops, but I think they are one of the few growers with a specially designed watering boom for their hanging baskets to apply the nematodes this way to the hanging baskets.

Nematodes are small, colorless, cylindrical round worms that occur naturally in soils throughout the world. Different species work best against different insect pests. Steinernema feltiae is primarily used against fungus gnat larvae and thrips pupae dwelling in the soil media. Fungus gnat larvae may be parasitized in any larval stage. Nematodes have traditionally been used against soil dwelling pests because they are sensitive to ultra violet light and desiccation.

The beneficial nematodes enter the insect host through body openings. These insect killing nematodes multiply within the host and release a symbiotic bacterium (Xenorhabdus spp.) whose toxin kills the target pest, i.e. fungus gnats. The fungus gnat larvae are killed in one to two days by blood poisoning. More than one generation of nematodes may develop in dead host insect in the growing media. The infective juveniles then exit the dead body and search for new hosts to infect.

Robots in the Greenhouse

CK Greenhouses in Cheshire gave a short demonstration of their robots, which are used to space their plants in both their greenhouses and outdoor mum fields. Here you can see them moving the pots from a pot to pot spacing to a final spacing.   They have a rechargeable battery so can work for 12 hours and use the reflective tape to orient themselves. The grower said that they were relatively easy to program and are a great labor saving tool. Watch the video to see the robots in action.

New Greenhouse Teaches Science of Gardening

New Greenhouse helps 4-H Center at Auerfarm Teach Youth the Science of Gardening

By Sarah Bailey, Master Gardener Coordinator, Hartford County Extension Center

 

Auerfarm greenhouseWinter may have been unusually cold and long this year, but there was a sunny and green oasis at the 4-H Center at Auerfarm. Spinach and herbs grew throughout the winter, to be joined by all manner of vegetables, herbs and flowers as the seasons shifted. Over the last year students planted seeds, weeded the ground-level beds and sampled fresh produce right from the source. The first killing frost is no longer an end to the growing season; it simply signals a shift into the new greenhouse. Funded by an anonymous $50,000 grant, the 20 x 48 foot polycarbonate rigid-walled structure provides both in-ground and bench-top growing space, along with room for classes and demonstrations. While heated, it is being run as a “cold house” with minimal non-solar heat in the winter, yet stays warm enough for several cold-hardy plant varieties. On a sunny January day, it feels like July!

The building is home to a variety of programs and events. Area schoolchildren take part in Farm to School programs, and Junior Master Gardener (JMG) participants learn about how plants grow, do plant science experiments, and plant and harvest produce. Teachers receive JMG program training to bring gardening and environmental hands-on curriculum back to their schools. Along with the specific youth programming, the greenhouse also hosts programs for the adult UConn Master Gardeners who help grow plants for the Foodshare production garden on the farm.

Additional growing space and an extended spring and fall growing season have allowed for additional gardening and food-related events throughout the year. An additional benefit has been the creation of venues for multi-generational experiences. Currently under development is a series on Gardening with Families along with a Saturday program on gardening and the environment for youth.
