The answer to 'how to install mulching' is to spread a 2-4 inch layer of organic mulch around your plants and trees. Mulch helps retain soil moisture, suppress weeds, and insulate plant roots from temperature extremes. Start by clearing away any existing weeds or debris from the area. Then apply the mulch in an even layer, being careful not to pile it up against the stems or trunks of plants.
For best results, replenish the mulch layer annually in early spring before the growing season begins. This will help maintain the benefits of mulching throughout the year. If you have a large landscape or are unsure of the right type of mulch to use, it's a good idea to consult with a professional landscaper for guidance.
