‘Susu’ is a variety of Giant Sorghum. Giant Sorghum itself is a Sorghum x Sudan Grass hybrid, which reaches around 2m tall and is therefore a very useful windbreak to protect more vulnerable crops. For example, a 3-6m strip of Giant Sorghum alongside a crop of Maize will provide ideal protection. Giant Sorghum has a deep root system and this enables it to withstand periods of drought. Giant Sorghum can be prone to lodging later in the season.
