Is it necessary to remove mulch when applying fertilizer?

• A. Yes, to enhance absorption
• B. No, broadcast fertilizer on top of the mulch
• C. Only if the mulch is old
• D. Yes, to prevent nitrogen loss

Answer: (B)

The correct answer is that it is not necessary to remove mulch when applying fertilizer, and you can effectively broadcast fertilizer on top of the mulch. Mulch serves multiple purposes in the landscape, including moisture retention, soil temperature regulation, and weed suppression. When fertilizer is applied over the mulch, it can still reach the soil as rain or irrigation water washes it through the mulch layer. It's important to mention that mulched surfaces can help prevent soil erosion and retain nutrients, which means that even with a mulch layer, nutrients can still be made available to the plants. The mulch can also slowly decompose over time, contributing organic matter back into the soil, which further aids in nutrient availability. Therefore, fertilizing over mulch is a common practice that can be effective without the need for removal.
