No real experience with trikes, but with tail draggers a powered turn radius can be minimized by getting all the way over left on back-taxi, then pointing the nose about 45 degrees back to the right and initiating a full left turn at the last opportunity before the right wing would clip the trees. Makes sort of a tear-drop turn rather than a U. Also gives maximum turning space as you're turning on a diagonal to the runway. Plus, you can apply a touch more power, making rudder, differential braking and P-factor more effective. On slippery surfaces like snow where braking is poor, you can have your passenger(s) hang on the inner wing strut while you power through a turn. Otherwise, yeah, shut down and spin it by hand.
A good method for rolling or pivoting a plane on slippery surface where footing is poor is to spin the tires by hand. Counter-rotate them for a pivot. Works easier with bigger tire sizes.
