In all leases of land or tenements, or of any interest therein, from month to month, the landlord may change the terms of the lease to take effect at the expiration of the month upon giving notice in writing at least thirty days before the expiration of the month. The notice, when served upon the tenant, shall operate and be effectual to create and establish as a part of the lease the terms, rent, and conditions specified in the notice, if the tenant shall continue to hold the premises after the expiration of the month. For the purpose of this section, notice may be served in any reasonable manner which actually informs the tenant of the changes in the terms of the lease.
