Mulches have a variety of reasons for being used in gardens. They help to control erosion and prevent weeds as well as retain moisture and insulate plants and roots. They do a lot of beneficial things for your garden. Different mulches work much better for different kinds of purposes. Every mulch you choose can have a good, or bad effect on your plants.
Key Takeaways:
- When we hear the word “mulch,” we oftentimes think of wood chips, straw or composts.
- However, landscape rocks are also generally described as mulch and do the same job.
- Because of the heat rock mulches attract, they work well to suppress weeds.
