Zoysiagrass Winter Fertilization: Question the November Application

Red Flags

A lawn company wants to apply pre-emergent + "non-nitrogen fertilizer for root growth" in November. This contradicts standard advice against fertilizing zoysia in fall.

What to Ask

• Request university research showing benefit of November fertilizer on zoysiagrass.
• Ask which winter annuals they're targeting—chickweed and annual bluegrass often germinate in October.
