We consider packing tree degree sequences in this paper. We set up aconjecture that any arbitrary number of tree degree sequences without commonleaves have edge disjoint tree realizations. This conjecture is known to betrue for $2$ and $3$ tree degree sequences. In this paper, we give a proof for$4$ tree degree sequences and a computer aided proof for $5$ tree degreesequences. We also prove that for arbitrary $k$, $k$ tree degree sequenceswithout common leaves and at least $2k-4$ vertices which are not leaves in anyof the trees always have edge disjoint tree realizations. The main ingredientin all of the presented proofs is to find rainbow matchings in certainconfigurations.
