We give a bound for n 0 (I) from which the depth function depth R/I (n) of the quotient ring by symbolic powers of a squarefree monomial ideal I stabilizes. In the unmixed codimension two case we show that depth R/I (n) is a non-increasing function of n and use this property to provide a sharp bound for n 0 (I).
