Planets and Plants

This article about how plants helped form the Earth’s surface is quite interesting, but the lede seems flawed.

If plants are the catalyst that turns rock into mud, once that mud exists, water will cut channels through it. And thus rivers, lakes, valleys, sedimentary rock, etc.

The question then is, will life develop on other planets that breaks down rocks into mud? That seems like the only requirement in order to have a sedimentary surface, like the Earth. The author blithely waves away this possibility.
