The parish of Dilwyn is dominated by agricultural land. Farming is a mix of arable and pastoral land, interspersed with many orchards. Arable crops are dominated by cereals, oil seed rape and potatoes. Special potato crops are grown to make Tyrrell's Crisps at the factory at Tyrrell's Court farm. Pastoral land is principally used for sheep grazing but there is also cattle rearing. Herefordshire is famous for the white faced Hereford breed of cattle. In the parish, at the Haven, the Lewis family have the oldest family owned Pedigree Hereford Herd in the world. Many small old orchards still survive, a lot were lost. Due to the modern demand for cider, many new orchards have been planted - mainly around Alton Court and Field's Place.

Dilwyn is one of the first villages on the the Black & White Village Trail which is named for the many timber-framed houses and buildings to be seen on the route. The Trail is a well signed tourist route through some of the prettiest villages and most beautiful landscapes in England. Starting from the ancient town of Leominster, the 40 mile circular trail leads west through a rich landscape of orchards, hopyards and distant hills, taking in the most picturesque black and white villages along the way as well as the little market town of Kington.
