Maples In The Landscape, Sheriden M. Hansen, Jaydee Gunnell, Andra Emmertson

All Current Publications

Maple trees (Acer sp.) are a common fixture and beautiful addition to Utah landscapes. There are over one hundred species, each with numerous cultivars (cultivated varieties) that are native to both North America and much of Northern Europe. Trees vary in size and shape, from small, almost prostrate forms like certain Japanese maples (Acer palmatum) and shrubby bigtooth maples (Acer grandidentatum) to large and stately shade trees like the Norway maple (Acer platanoides). Tree shape can vary greatly, ranging from upright, columnar, rounded, pyramidal to spreading. Because trees come in a range …

Conserving Water Through Modular Planting Design: Water-Wise Templates For Ogden's Residential Front Yard Landscapes, Jessica Clements

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Due to the arid climate of the Wasatch front and the projected population growth in the next thirty years, water conservation is essential. Consequently, because the landscape consumes 60% of Utah residences’ purified drinking water, water-wise landscaping needs to be a priority. This thesis creates water-wise landscape templates that can be applied to the front yards of Ogden rental properties using a modular planting method. This study determines best practices by researching topics such as water-wise plants for Northern Utah, templates utilized in other areas, modular planting, and existing organizations with similar goals. This results in a user-friendly guide that …

High Tunnel Pest Management - Aphids, Nick Volesky, Zachery R. Schrumm

All Current Publications

Aphids are a common pest found on high tunnel crops such as fruits, vegetables, ornamentals, grasses, and weeds. Four aphid species commonly found in Utah in high tunnels are green peach aphid (Myzus persicae), melon aphid (Aphis gossypii), potato aphid (Macrosiphum euphorbiae), and cabbage aphid (Brevicoryne brassicae). This fact sheet describes different aphids and reviews the aphid life cycle. It also addresses how to monitor for damage caused by aphids and cultural, biological, and chemical controls.

Watering The Landscape: Make It Easier With Evapotranspiration (Et), Candace Schaible, Kelly Kopp, Helen Muntz

All Current Publications

The American lawn is our nation’s single largest irrigated “crop” (Lindsey, 2005). In Utah, roughly 65% of our drinking water is applied to residential and commercial landscapes (Center for Water Efficient Landscaping, 2020). Landscapes are typically overwatered, which is why residential and commercial landscape watering is estimated to be one of the largest sources of potential water conservation in the urban setting (Endter-Wada et al., 2008). Plant materials also provide many environmental benefits, such as erosion control, water filtration, and temperature reduction. Knowing how much water to apply to the landscape can be a challenge and is one reason many …

Managing Suckers Around Fruit Trees, Samuel Johnson, Teryl Roper, Xin Dai

All Current Publications

Many types of fruit trees produce suckers around the base of the tree. Crown suckers arise in the area immediately surrounding the tree trunk (Photo 1), and root suckers can arise from roots further away from the trunk. Not only are suckers around trees unsightly, but they can also harbor insect pests like wooly apple aphid and provide points of entry for diseases like fire blight. If suckers are profuse, they interfere with in-row weed management and can absorb systemic herbicides such as glyphosate. Some rootstocks used for fruit trees such as M.7 for apples and Mazzard for cherries are …

Preparing And Improving Garden Soil, Katie Wagner, Melanie Stock, Larry A. Sagers

All Current Publications

A great garden starts with healthy soil. In Utah, there are unique considerations for creating and maintaining healthy soils. Native Utah soils are relatively low in organic matter. One of Utah’s most troublesome, pH-related deficiencies is iron chlorosis, a deficiency of plant-available iron. Soil salinity easily increases in Utah. This fact sheet addresses these challenges to help gardeners transform garden soils from brutal to beautiful!

Using Degree Days To Time Treatments For Insect Pests, Marion Murray

All Current Publications

Insecticides that are applied for a perennial insect pest based on a calendar date often result in poor insect control and a waste of resources. Insect activity varies from year to year depending on weather. For example, in Logan, Utah, eggs of the apple pest codling moth began hatching on May 15 in 2005, May 5 in 2006, and April 30 in 2007.

Relative Salt Tolerance Of 22 Pomegranate (Punica Granatum) Cultivars, Youping Sun, Genhua Niu, Joseph G. Masabni, Girisha Ganjegunte

Plants, Soils, and Climate Faculty Publications

A greenhouse experiment was conducted to determine the relative salt tolerance of pomegranate (Punica granatum) cultivars. Twenty-two pomegranate cultivars were irrigated weekly with a saline solution at an electrical conductivity (EC) of 10.0 dS·m–1 for 4 weeks and subsequently with a saline solution at an EC of 15.0 dS·m–1 for another 3 weeks (salt treatment). Another group of uniform plants was watered with a nutrient solution without additional salts at an EC of 1.2 dS·m–1 (control). No visual foliar salt damage (leaf burn, necrosis, or discoloration) was observed during the entire experimental period; however, salt treatment impacted pomegranate growth negatively, …

Responses Of Marigold Cultivars To Saline Water Irrigation, Youping Sun, Genhua Niu, Christina Perez, H. Brent Pemberton, James Altland

Plants, Soils, and Climate Faculty Publications

Marigolds (Tagetes sp.) are ornamental plants with fine-textured, dark green foliage, and yellow, orange, or bicolored flowers. The relative salt tolerance of eight marigolds [‘Discovery Orange’, ‘Discovery Yellow’, ‘Taishan Gold’, ‘Taishan Orange’, and ‘Taishan Yellow’ African marigold (Tagetes erecta); ‘Hot Pak Gold’, ‘Hot Pak Orange’, and ‘Hot Pak Yellow’ French marigold (Tagetes patula)] was evaluated in a greenhouse experiment. Plants were irrigated weekly with nutrient solution at an electrical conductivity (EC) of 1.2 dS·m⁻¹ (control) or saline solutions at an EC of 3.0 or 6.0 dS·m⁻¹ (EC 3 or EC 6). Marigold plants …

Phosphorous And Potassium Fertility Management For Maximizing Tart Cherry Fruit Quality And Productivity On Alkaline Soils, Sean D. Rowley

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Suitable orchard land in regions of the Intermountain West is becoming more limited due to urban sprawl. With the loss of suitable farmland, increasing production costs, and the lack of sound fertility information for these regions, fruit growers face challenges to produce high quality fruit for market demand. Current standard management practices are not sufficient to optimize yield and fruit quality in the marginal farm land that is currently be used for fruit production. Fertility management of orchard trees is vital to tree health, yield, and fruit quality.

Three different approaches were used to investigate the effects of Phosphorus (P) …
