  1. Hola Lucas. En mi país (el Reino Unido) está bien cosechar trufas siempre y cuando se obtenga el permiso del propietario… si estás en la tierra de otra persona, por supuesto. Ten en cuenta que a veces esta cosecha deja un poco de desorden – ¡limpia el suelo después de ti para estar seguro! Espero que esto ayude – ¡y feliz cosecha! 🙂
