Which statement is NOT a listed timing for two fertilizer applications annually?

• A. Mid to late spring
• B. Late fall
• C. Late summer
• D. Early winter

Answer: (D)

Fertilizer timing is about matching nutrient supply to when the grass can actually use it and when conditions minimize losses. For two applications a year on most turf, the usual windows are mid to late spring, when growth is ramping up, and late summer to early fall, when growth continues under warm conditions but before dormancy. Early winter, however, isn’t used because many grasses are dormant and uptake is minimal, so nutrients can be wasted or lost to leaching or runoff. So the statement that isn’t a listed timing is early winter.
