Native Grasses for Texas

One may be surprised to learn that bermudagrass and bahiagrass are NOT native to Texas much less to the United States. There are numerous species of grasses and forbs that can be utilized for forage throughout the state of Texas. Keep in mind as we select forages we need to be mindful of our production system goals, location (soil type and rainfall), and the nutrient needs of our livestock (and/or wildlife). Many livestock producers are considering forage species and varieties that do not require as much fertilizer as… Read More →

Impact of Sub Freezing Temperatures on Warm-Season Perennial Grasses

Warm-season perennial grasses are the basis of pasture systems and livestock production in Texas. The most prominent warm season species are bermudagrass (seeded and hybrid) and bahiagrass. Neither of these species is native to the state of Texas but they are well adapted to Central and East Texas. Unfortunately they can be greatly impacted by cold winter temperatures. Central and East Texas have seen record temperatures in late December. Many may be concerned about whether or not their warm season forages have survived these weather conditions.   Bermudagrass… Read More →

Common Winter Weeds in Pastures and Hay Meadows

Buttercup (Ranunculus spp) Spray buttercup in late February or early March before it flowers. This weed is easily controlled with 2,4-D amine, Metsulfuron 60 DF, Cimarron Plus, Grazon P+D, GrazonNext HL and dicamba + 2,4-D (Weedmaster). In dormant bermudagrass/bahiagrass glyphosate (Roundup) will control buttercup at normal use rates.   Groundsel (Senecio spp) Metsulfuron 60DF or Cimarron Plus has proved to be the most effective herbicide for groundsel control. Apply in the rosette stage (~March). Grazon P+D provides partial control.   Red Sorrel (Rumex acetosella)   Grazon P+D provides… Read More →

Weed of the Week: Buttercup

Buttercup (Ranunculus species): One of the many yellow flowering weeds that we fight in pastures and hay meadows. Buttercup is a winter annual that thrives in weak or thin pastures. There are several species of this winter annual. They differ mainly in leaf shape and growth, but all produce characteristic bright yellow blossoms. March to early April is the best time to kill buttercup. The goal is to spray buttercup before bloom.   Fertilizing and liming to soil test recommendations and efficient utilization of pastures or hay fields are… Read More →

Weed of the Week: Broomsedge Bluestem

Broomsedge Bluestem (Andropogon virginicus L.) is a warm season perennial grass found throughout Central and East Texas. Broomsedge growth begins as temperatures consistently stay above 60 degrees F. It produces many seeds that are distributed by wind. It is a poor competitor, has poor nutritive value for livestock and low palatability. Broomsedge can quickly become the dominant species in over-grazed, low pH (< 5.5), low fertility, eroded soils where desired vegetation will not thrive. Since this plant thrives on low pH and low fertility soils, soil testing is… Read More →

Winter Weeds: Do they matter?

As forage producers, we focus most of our energy on our warm season perennial pastures and hay meadows (bermudagrass, bahiagrass, etc.). That means most of our weed control efforts are also focused on warm season weeds (such as carolina horsenettle, blackberry, etc). Unfortunately, cool season weeds can be just as detrimental to our warm season perennial forages.   Annual ryegrass…a cool season annual forage often utilized by livestock producers for winter grazing. However, it’s often deemed an enemy of many a hay producer in East Texas. Later maturity… Read More →

Fertilization of Winter Pasture

Fertilization of winter pasture should be based on a soil test to maximize forage production and prevent applying more fertilizer than is needed. Nitrogen fertilization of small grain and small grain-ryegrass mixtures can be split in 2 to 4 equal applications during the growing season. Two applications are often sufficient in Central Texas with lower rainfall and heavier textured soils. Three or four applications are required on the sandy soils in East Texas because of low nutrient holding capacity and high rainfall. Phosphorus and potassium can be applied… Read More →

Weed of the Week: Thistles

If left uncontrolled, thick thistle stands can reduce grazing and result in less forage production. A single thistle plant can produce at least 4,000 seeds, which increases the chance for higher thistle populations in the pasture the following year. Consequently, management practices need to be conducted prior to flower formation for effective thistle control. Even if thistles have not infested your pasture in the past, it is ideal that your pastures are scouted in late fall through mid-spring (November to March) to ensure that thistles do not get… Read More →

Cool Season Annual Forages: To Plant or Not To Plant…Now or Later?

  Ideally we would like to plant to soil moisture. Summer pastures should be overseeded in October and early November depending on location. Delaying planting may give us an opportunity to plant to soil moisture depending on rainfall. Delaying planting too late (late November or December) will decrease overall forage production as well as result in a shorter grazing period.   If  we do have adequate moisture this winter be prepared to manage any winter forages planted, especially those overseeded into existing warm season perennial sods (bermudagrass, bahiagrass,… Read More →
