1. Organic Mulch Options
When it comes to mulching your garden, organic options are not only eco-friendly but also provide numerous benefits for your plants. Here are five organic mulch options to consider:
1.1 Compost
Compost is a fantastic choice as it not only provides nutrients to your plants but also helps improve the soil structure. Using compost as mulch promotes soil moisture retention, suppresses weed growth, and creates a healthy environment for beneficial microorganisms. Simply spread a layer of compost around your plants, ensuring not to pile it up against the stems.
