You should fertilize your lawn three to four times during the growing season (typically in spring and fall, but not summer). While it’s good to keep your lawn on a regular feeding schedule, it’s also important not to overfeed your lawn. 

Over-fertilizing your lawn can actually cause damaging effects, including but not limited to: 

• Burning of grass 
• Yellowing or browning of grass 
• Dead grass patches 
• Damaged root system
