Bark Mulch
Pine Straw
Synthetic mulch
Synthetic mulches retain their color, come in a wide variety of colors and do not decompose over time like organic mulch. Ideally suited for beds that are close to the foundation of your home due to inability to rot or mold. Black plastic landscaping material is great up against the home, and placing synthetic mulch that mimics shredded bark mulch is a great choice. As with any type of plastic, it can become very hot in summer so make sure there are sufficient holes to allow for rain and airflow. With vegetable gardens, it is generally best to avoid synthetic mulches since there is ongoing debate on the chemicals of synthetic mulch leaching into the ground and because they are not biodegradable, there is no telling where it could end up years down the road.
