A topology $au$ on a set $X$ is called maximal connected if it isconnected, but no strictly finer topology $au^* > au$ is connected. Weconsider a construction of so-called tree sums of topological spaces, and weshow how this construction preserves maximal connectedness and also relatedproperties of strong connectedness and essential connectedness. We also recall the characterization of finitely generated maximal connectedspaces and reformulate it in the language of specialization preorder andgraphs, from which it is imminent that finitely generated maximal connectedspaces are precisely $T_rac{1}{2}$ tree sums of copies of the Sierpi'nskispace.
