Summarize this article in one sentence.
Ryegrass is characterized by glossy leaves and clumpy flowers. And given the reflective ability of its surface, it has a distinctive shine that separates it from other types of grass. They also possess reddish-colored seedheads. Using chalk as a marker makes it easier to keep track of all the rye glass that needs removing. It can also be used to track new growth. You can also use your chalk to mark regions of removed ryegrass to track any new growth. Although ryegrass roots can reach up to 20 inches (51 cm) deep, digging at this depth should sufficiently disrupt the root system. If you're having trouble digging, pour water onto the soil to soften it. This will prevent it from getting sunlight and prevent growth of ryegrass seeds in the soil. You can also use herbicide-infused fabric.   Place heavy rocks or bricks onto the edges of the fabric to ensure that it is held down The best time to place herbicide-infused fabric is the summer. After removing your fabric, drag a thatch rake over the area to aerate it prior to planting any seeds. Use the same motion as you would with a standard rake, allowing the spokes to dig into the thatch. Pull it upwards to loosen and lift the thatch from your lawn. Keep an eye out for remaining seeds. Ryegrass seeds can germinate in 3 days. Remove all seeds that you find from the area.

Summary:
Locate the ryegrass you want to remove. Sprinkle white chalk powder on ryegrass to identify it. Use your spade to dig 2 inches (5.1 cm) around the marked area. Cover your ryegrass regions with a landscaping fabric. Remove the fabric after 14 days and dig up the dead grass.
