No; she can. She is shown extracting water from the grass by her palms when on the ground in that same episode. In fact when standing upright, she draws a whole ring of water that encircles her. She does so again after evading Aang/Sokka...and then a fourth time when defending herself against Sokka's sword / freezing Aang.

Then...to stop Sokka, she shrivels a tree / withdraws all the water from it and freezes him.

You're underestimating Katara.... :)
