5. Choose Mulch with Good Drainage for Clay Soil

Southwest Missouri’s soil often contains a high clay content, which can hold water for extended periods. When mulching over clay-heavy soil, choose mulch that promotes good drainage and prevents water from sitting at the surface.

• Use Coarser Mulch: Coarser materials like large wood chips and bark nuggets allow better air and water movement, reducing the chances of waterlogging.
• Consider a Thin Layer of Mulch Over Compacted Clay: For areas with compacted clay soil, use a slightly thinner layer (around 2 inches) of mulch to avoid trapping too much moisture.

6. Consider Seasonal Adjustments

Missouri weather can vary significantly from season to season. Adjusting your mulching practices based on the time of year can help protect trees from root rot.

• Spring: Early spring is an ideal time to add a fresh layer of mulch before new growth begins. Be mindful of spring rain patterns, and avoid over-watering if rainfall is heavy.
• Summer: In summer, mulch helps conserve soil moisture and keep roots cool. During dry spells, keep an eye on soil moisture levels and ensure mulch isn’t contributing to waterlogged soil.
• Fall: Apply a fresh layer of mulch in fall to protect roots from the winter cold, but ensure it’s not too thick.
• Winter: Monitor mulch levels during winter. Too much mulch can prevent proper drainage if snow or rain is heavy.
