By TIM WANYONYIMore by this AuthorGrevillea robusta is a fast-growing evergreen tree that is among the most common in Kenya. There is little tree planting in zones I and VII, because I is arid and no tree can survive while VII is in the natural public forests. Grevillea grows in all the remaining five zones where annual rains range from less than 400mm to more than 1,400mm. Once established, grevillea is a hardy drought-resistant tree that requires little care. Through this effort, farmers have planted more than five million grevillea trees since 2010.
