To encourage butterflies we need to plant host plants that will proving nutritious leaves for the caterpillars, their favourite nectar plants and a place for them to drink fresh water. This can be made in a shallow dish or an old birdbath.Fill with sand and place some sticks and stones for the butterflies to land on. Add water or stale beer. They do like their beer! You could also add over ripe fruit as this is also a source of nectar. Sit back and wait for the butterflies to enjoy their new drinking ‘fountain’.
