Landscape drawing often requires you to draw grass. (Of course it does.) If you want to create a realistic landscape drawing, you've got to be able to draw realistic grass. Many people struggle with drawing grass that actually looks realistic, but this doesn't have to be the case.
Learning how to draw realistic grass is a matter of understanding how grass grows and recognizing that grass doesn't grow as uniform lines.
Drawing grass how it grows is important. What I mean by this, is that grass grows up from the ground. This is how you should make your lines directional. Begin them at the ground and move them up towards the sky.
Grass doesn't grow with uniform lines however. Instead grass creates lines that angle and taper at different lengths. Understanding how to represent this in a drawing is a huge key to success.
Grass is not just green either. It's made up of lots of colors. Recognizing these colors and incorporating them in your drawing is also important.
