Since she can controll mud, she can probably controll water too (unless she actually controlled the earth in the mud and the water simply stuck to it), but everything she manipulated so far was made of matter.

Fire or lightning (for example) are different, so I'm not so sure that she could controll those as well.

She certainly didn't try to controll the fire with which Natsu blew the acidic jelly aside in the Deliora arc.
