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 →


During the dormant season we often get anxious for warm weather and green pastures so we start thinking about renovation. Renovation is a practice or series of management practices which “restores the vigor” or “makes new again.” In pasture management, renovation refers to improvement of a permanent pasture by changed management. Renovation of bermudagrass pastures may be as simple as soil testing and applying proper fertilization; or, it may be as complex and intensive as destroying the existing sod, preparing a seedbed and sprigging again.   Some renovation… 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: 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 →

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 →

Feeding Hay to Reduce Waste

On many farms, hay feeding losses are as high as storage losses. Some hay losses during feeding can be expected with any feeding system, but the amount of loss varies with the system used. The major objective for any feeding system should be to keep loses to a practical minimum level, thus permitting animals to consume the majority of hay offered at feeding. Feeding losses include trampling, leaf shatter, chemical and physical deterioration, fecal contamination, and refusal. Feeding in only one area can cause excessive sod destruction, usually… Read More →
