Congo grass does have certain stress tolerances that are disadvantages to poor farmers and breeding these out in the future would add significant value to this crop. It demands a relatively high fertility soil for good growth as well as adequate fertiliser use if there is persistent grazing or cutting of the crop. Heavy frosts will kill this crop and a light frost will make future regrowth very slow. Congo grass flourishes well in a well drain soil and has a poor tolerance to floods and heavy rains.[1]
