The author extends a theorem on packing arc-disjoint arborescences by \textit{N. Kamiyama, N. Katoh} and \textit{A. Takizawa} [Combinatorica 29, No.~2, 197--214 (2009; Zbl 1212.05209)]. As a consequence, the problem of finding minimum-weight arc-disjoint arborescences that span given convex sets with roots can be solved in polynomial time.
