    What’s Your Flavor? Bee Preferences for Crape Myrtle Cultivars

    Crape myrtles are popular landscape shrubs and small trees. Native to China, Japan, and Korea southward to Oceania, crape myrtles have been cultivated in the U.S. for more than 175 years. Cultivars range from 3-ft shrubs to 30-ft-tall trees, and they are graced with large panicles of white, pink, lavender, purple, red, and many colors in between. Among cultivars, crape myrtles have a wide range of tolerance to key pests and diseases, such as powdery mildew, flea beetles, crape myrtle aphids, and Japanese beetles. The plant’s flowers are widely admired by humans and can serve as nectar and pollen sources for pollinators. With the recent decline in pollinator health and diversity, pollinator visitation, pest susceptibility, and horticultural attributes should all be considered when choosing crape myrtle cultivars for home and commercial landscapes.

    Equipment Maintenance and Troubleshooting for the Landscape and Garden

    This publication covers routine maintenance and troubleshooting for common motorized equipment (small engine) that is used by small farmers and gardeners. Gardening and landscape equipment can be an expensive investment for both consumers and professionals. However, quality equipment can last a lifetime when cared for properly. Typically, you get what you pay for when it comes to equipment. Higher quality equipment certainly costs more upfront, but usually has fewer problems and will tend to outlast bargain-type tools. With name-brand equipment, parts also tend to be
    more readily available. We recommend that you purchase the best equipment you can afford and learn how to take proper care of your equipment to protect your investment. For the garden and landscape, motorized equipment can include everything from a string trimmer to a full-size garden tractor. Most garden equipment is powered by either a two-cycle or four-cycle engine. Two-cycle motors mostly are found on smaller handheld equipment, such as chainsaws, tillers, and trimmers. Four-cycle motors typically are found on larger equipment such as lawnmowers, tillers, and garden tractors, which have separate reservoirs for their gas and engine oil. When properly maintained, both types of motors are quite reliable. Sometimes, very basic issues may keep motors from functioning well. All motors require three basic things to run properly: fuel, fire, and air. If any one or more of these three elements is lacking, the engine will either run poorly or not run at all.
