They have long tap roots that can reach the deep water table, thick bark to resist annual fires, trunks that can store water, and leaves that drop of during the winter to conserve water. This would be economically feasible for resource poor farmers. Hay harvested at a later stage of maturity has a low protein content and a high fibre content, particularly in the stems, and it should be supplemented when fed to ruminants with nutritional requirements higher than those necessary for maintenance. But thats not an issue for the wasps who lay their eggs inside the fruit. Its final height can be anything up to a massive 100 feet.

The plants have deep, spreading root systems that allow them strength and moisture during times of drought. Hyparrhenia is a genus of over 50 species of grasses. Its dense growth protects the soil and conserves moisture, creating the perfect habitat for insects. Rhodes grass gives an increased response to phosphorus in some areas and usually a spectacular linear response to nitrogen in the presence of adequate phosphorus and potassium, both in yield and in crude protein content. It can often be found growing on top of termite mounds. In the rhodes grass savanna, animals graze on the grasses that grow there. However, hay alone is unlikely to meet the nutritional requirements of productive ruminants and must, therefore, be supplemented (Mero et al., 1998;Mtenga et al., 1990; Mupangwa et al., 2000; Osuga et al., 2012).
