Ground cover help- mud and mulch beds are washing away
We moved into a new house. The landscaping is a mess. All the mulch beds are bare dirt and on slopes. During heavy rain we get mud/water falls down the tiers in the pics and what little mulch is in the beds out front washes into the grass. What can I put down? More mulch? Rocks? I'd rather not use plants as I don't want to help critters and bugs find homes. Low to no maintenance is key.
