Extending The Garden Season, Taun Beddes, Michael Caron, Sheriden M. Hansen, Jaydee Gunnell
All Current Publications
Many homeowners have the dream of growing fresh vegetables year-round. Unfortunately, in colder climates, this is only possible using a complete greenhouse with supplemental heating/cooling and lights. Greenhouses can be excessively expensive to maintain and heat, making them impractical for most homeowners. This is not only due to cold winter temperatures but shorter day lengths and lower available light that must be offset artificially. There are practical, less expensive ways to obtain self-grown produce earlier and later in the growing season, though, by using season-extending techniques. These include using equipment such as cold frames, high tunnels, low tunnels, floating row …

Abiotic Disorders Of Tomatoes, Nick Volesky, Marion Murray, Sheriden M. Hansen, Maegen A. Lewis
All Current Publications
Monitoring tomato plants regularly from seedling to harvest allows for early detection of abnormal conditions. Although tomato plants can be attacked by a variety of living organisms (insects, mites, pathogens, vertebrates), nonliving (abiotic) conditions can cause just as much damage. Abiotic diseases in tomato plants can arise from nutrient deficiencies, temperature extremes, abnormal lighting, chemical application, changes in water uptake, mechanical damage, genetic mutations, and more. This guide will cover most of the abiotic disorders and diseases that can affect tomatoes in Utah.

Fall-Bearing Cultivars: A High Tunnel System For Early Production, Alyssa Palmer, Brent Black
All Current Publications
Fresh red raspberries are a consumer favorite in Utah and have a high value but short shelf life, making them an excellent candidate crop for local direct market sales. However, Utah’s high-elevation valleys often experience harsh winter temperatures and short growing seasons, limiting raspberry yields. Raspberry plants exhibit one of two fruiting patterns: the summer-bearing type or the fall-bearing varieties, also referred to as “ever bearers” because of their ability to produce both fall and summer crops. These may be better suited in areas with harsh winter conditions that cause cane dieback. High tunnels can be an effective tool in …

Many new cold-hardy cultivars have been introduced over the last few decades, including both wine and table types. However, many of these newer cultivars have not been adequately tested in Utah’s unique climate. Utah State University Extension conducted a grape cultivar comparison planting in Lehi, Utah. This fact sheet reviews the outcomes of the study and offers information on tested varieties that have …
Low Tunnels For Field Cut Flower Production, Shannon Rauter, Melanie Stock, Brent Black, Dan Drost
Low Tunnels For Field Cut Flower Production, Shannon Rauter, Melanie Stock, Brent Black, Dan Drost
All Current Publications
Cut flower production in Utah can be limited by cold winters, late-spring freezes, daily temperature fluctuations, canyon winds, and intense sunlight. For growers who lack the space to construct a high tunnel, low tunnels can advance, extend, and improve seasonal production. Temperature increases from low tunnels during winter and spring can increase emergence and yield compared to unprotected beds, but require venting to avoid heat damage. During summer, low tunnels easily transition into shade structures that provide cooling and protection from the sun. This fact sheet describes a simple and cost-effective low tunnel design with metal-conduit hoops that are tall …

All Current Publications
Powdery mildew is one of the most easily recognized fungal plant diseases. It is categorized by spots or patches of white-to-gray powder-like growth on foliage, stems, or fruit. Roughly 700 species exist that infect grasses, ornamentals, weeds, fruit trees, landscape trees, shrubs, and vegetables. The closely related species of fungi that cause powdery mildew are host-specific, meaning they cannot survive without the proper host. Powdery mildew fungi spread in conditions of low rainfall and hot temperatures, making Utah’s climate the perfect environment. This fact sheet provides information on powdery mildew and its management.
