They are often more attractive due to their fine leaf texture, greater density, and dark green color. Texas A&M Veterinary Medical Diagnostics Laboratory, Texas A&M College of Agrculture and Life Sciences, Hybrid bermudagrasses also differ from common varieties in that they require more fertility, mowing, and thatch management for maximum performance. Mowing too low removes too much leaf tissue, and will cause inadequate density, root development, and a reduction in overall turfgrass health. Instead, apply irrigation if possible (less than .25 inches) to help move the fertilizer into the soil. Common winter annual grasses in lawns include annual bluegrass (Poa annua) and rescuegrass. The most accurate way to determine the nutrient status of soils is through soil testing. Texas Tough is a mixture of seeded bermudagrass consisting of one-third Giant and two-thirds Common bermudagrass, one-half of which is hulled and the other half unhulled. When this happens, turfgrasses may wilt, turn brown, and go dormant. Be careful not to set the mower too low, as it may scalp the lawn. This happens because turfgrass leaves grow upward to compete for light with neighboring plants. Once you select an appropriate fertilizer, you must determine the appropriate application rate. For bermudagrass home lawns, mowing must often be done weekly during the growing season, or as often as necessary to prevent scalping. If manual removal is preferred, take care to remove the entire plant including the roots because this will allow for regeneration in that area. It is difficult to control perennial grassy weeds such as dallisgrass or bluestem (Bothriochloa species). Broadleaf weeds such as clovers (Trifolium and Medicago sp) and dandelion (Taraxacum officinale) usually have net-like leaf veins though leaf shapes vary widely (Figure 4). These herbicides will not be effective when daytime temperatures are less than 60 °F. Too much shade can cause turfgrass to lose density and allow shade tolerant weeds to thrive. These carbohydrates are used to produce new leaves, stems, and roots. St. Augustine is a good choice for a shady Texas lawn with mature trees, as it prefers … Products that contain sulfosulfuron (Certainty) or imazaquin (Image Kills Nutsedge) will control yellow and purple nutsedge. From these nodes, lateral buds develop that produce stems measuring from 5 to 40 cm in height. This form tells when, where, and how to collect soil samples. Among bermudagrasses, Celebration and TifGrand are two varieties that have improved shade tolerance and may perform adequately in moderate shade. Bahiagrass is a pasture grass that invades lawns primarily in East Texas. Mowing is one of the most important cultural practices for managing turfgrasses.

However, when plants enter drought stress, the stomata close to prevent losing excess water. Multiply these three values together to determine how much total fertilizer to apply. Applying a pre-emergence herbicide in the fall is less common, but in lawns with a history of these weeds, certain pre-emergent herbicides listed in Table 1 can be applied from mid- August to mid-September. Texturf-10 is sensitive to chlorinated hydrocarbon insecticides, turning a straw color several days after an application of these materials. Test the soil to know the amount of nutrient and the amount of lime to add. As plants grow, they take in atmospheric carbon dioxide (CO2) and convert it into carbohydrates through photosynthesis. When weeds are present, it is important to identify and address the cause of thinning turfgrass before treating for weeds.

Example: A homeowner wants to apply 1.0 lb of nitrogen per 1,000 ft2 to a 4,500 ft2 lawn and is purchasing fertilizer with a 15-4-9 analysis. Bermuda grass grows best when the soil is very rich in nitrogen, consuming much more than other grass varieties. This selection is based on the soil test results, whether the turfgrass has high- or low-traffic, whether the soil is sand or clay, the target application rate, and the desired outcome. Over-irrigating in the spring and fall can also increase the incidence of diseases such as large patch and take-all patch. Exceptions to this reduction include southern parts of Texas where warm-season turfgrasses do not go fully dormant, sandy soils that are well-drained, or newly laid sod. The best time to apply these herbicides is mid to late spring after sedges have emerged from the canopy. Proper variety selection and management practices are vital to preventing or limiting weed infestations. Remember that green leaf tissue in turfgrasses is where photosynthesis takes place. Another method, which uses water responsibly, is to use evapotranspiration (ET) rates as a reference point for scheduling irrigation. Sources of variation in Cynodon dactylon (L).

To control weeds in home lawns, please consider the following: 1) Determine whether it is a grassy weed, broadleaf weed, or sedge. Many perennial broadleaf weeds can be treated with the same herbicides (Table 2) that control annual broadleaf weeds, but their perennial growth habit, makes control more difficult. Remove no more than one-third of the leaf area with any one mowing. Texas Native is a fine textured Bermuda grass used in commercial applications which has a high formation of seed heads producing viable seeds. One way to schedule irrigation is by inspecting the turf for wilting leaves and a blue-gray color throughout the lawn. Slow-release nitrogen sources such as sulfur coated urea (SCU), polymer coated urea (PCU), urea-formaldehyde, methylene urea, and organic products provide a much slower, long-term response. These herbicides are effective only if they are applied uniformly and are watered into the soil by rainfall or irrigation before the target weed emerges. Common Bermuda Grass Germinating from Seed. Effects of temperature and relative humidity on the toxicity of glycophosate to bermudagrass (Cynodon dactylon).
