Lawn fertilizer burn shows up as streaks of discoloration on grass blades and dry brown patches of dead lawn grass.
Lawn burn from chemicals or heat usually looks the same. It will be a strip, patch or patches of yellow, tan or straw coloured grass that will appear within a day or so. The greater the over dose, the quicker it will appear.
The path to recovery for burnt grass can test a gardener's patience as patience is key. The duration of recovery hinges on the severity of the damage and the steps taken to rehabilitate the lawn. With diligent care, even the most damaged lawns can show signs of life within a few months.

Chlorophyll is produced when your grass has enough nitrogen in its system, which gives it that desirable green color. However, when it's yellowing, it could be a sign that it is lacking in nitrogen. Fertilizers provide this nutrient, along with others, to the soil, which helps to promote healthy, green grass.
If the dried, burnt areas are limited to small bare patches in the lawn, then you may be able to encourage growth there by watering them generously and fertilizing those areas. However, be aware that fertilizing grass during hot weather can make grass less tolerant to heat.
