The answer to 'mulch schedule' is that most experts recommend applying a 2-4 inch layer of mulch around your plants and trees 1-2 times per year. Typically, the best times to apply mulch are in the spring and fall. Applying mulch helps retain moisture in the soil, suppress weeds, and insulate plant roots from extreme temperature changes.
When applying mulch, be sure to keep it a few inches away from the base of plants and trees to prevent rot. Replenish the mulch as needed throughout the year to maintain the recommended depth. For best results, use a high-quality, shredded or chipped mulch made from natural materials like wood, leaves, or bark.
