Research has shown that a landscape that has been carefully planned and installed and properly managed will be healthier, less prone to insects and diseases, and will require less irrigation. Georgia’s landscape and turf industry and UGA Cooperative Extension are urging citizens to implement inexpensive and easy-to-perform landscape management practices that decrease the need for irrigation and/or lead to greater efficiency of irrigation when it is needed. This publication provides tips about planning, planting and maintaining the landscape to save water.

Centipedegrass Decline
Centipedegrass is ideal for the homeowner who wants a lawn that needs little care. It can be established by either seed or vegetative parts and does not require much fertilizer. Compared to other lawn grasses, it is moderately resistant to insects and diseases. Although centipedegrass is a relatively low maintenance grass, proper management is still required.

Spring dead spot (SDS) is a persistent and destructive disease of bermudagrass (Cynodon sp.) in Georgia. The disease can be problematic on lawns, landscapes, golf courses (bermudagrass greens, tees and fairways) and sports fields. The disease is particularly prevalent and damaging in north Georgia, especially in the Piedmont region. However, SDS can be observed throughout the state after harsh winters and in areas where bermudagrass has been exposed to freezing temperatures for extended periods of time. The disease has also been observed in zoysiagrass, although less frequently. This publication explains how to identify and control Spring Dead Spot in lawns in Georgia.

Properly maintaining, calibrating, and adjusting a seed drill before planting is an important part of ensuring the successful establishment of forage or cover crops. Seed may be placed at a depth that is too deep or too shallow if the equipment is not properly prepared and set. Too much or too little seed may be planted if the equipment is not properly calibrated. These planting mistakes may result in a poor stand, greater weed competition, lower yields, and/or reductions in forage quality. Conversely, planting more seed than required can unnecessarily increase establishment costs and can sometimes result in reduced yields. After investing in the seed and committing the time to plant a field, taking a few extra steps to ensure that investment bears fruit is well worth maintaining, calibrating, and adjusting the drill.

Boom sprayer calibration using conventional methods (catching flow for certain time or distance) for large (60-90 ft; 54-72 nozzles) boom sprayers can be a time-consuming process. This short publication outlines steps to take to verify nozzle output and calibrate a boom sprayer, including tables with useful information on flow rates at multiple speeds for two common nozzle spacings and an equation for calculating rates if needed.

Johnsongrass (Sorghum halepense) is a warm-season perennial weed in pastures and roadsides throughout central and northern Georgia. Populations may germinate from seed in spring after overwintering in the soil. However, Johnsongrass primarily emerges from dormant rhizomes in areas with a history of infestations. Rhizomes are belowground stems that produce daughter plants and storage reserves for new growth in spring. The persistence of Johnsongrass is primarily associated with extensive rhizomatous growth that enable populations to spread laterally and dominate areas by preventing desirable species from flourishing.
