How and When to Apply Mulch?
Spring/Summer is the ideal season to apply mulch when soil temperatures are warmer. Spread a 2″-4″ layer of finely processed mulch around annuals and perennials. Avoid mulching directly around stems of plants and trunks of trees. Spread evenly and avoid compacting or matting down. Rake at 4-6 month intervals to rejuvenate beds and allow aeration to plant roots.
