Answer: The dead patches in your lawn might be caused by a number of things but the easiest way to remedy the situation is to rake out the dead grass, rough up the soil and reseed the areas this spring. As for the fallen leaves, if they are allowed to remain on the lawn they will essentially suffocate the grass. Try to rake them up once a week to ensure that your grass gets the sunlight and good air circulation it requires. While leaves do break down and provide nutrients as they decompose, it would be better to rake them up and compost them in a separate place. After they have decomposed you can use them as mulch around your flowers or vegetables.
Best wishes with your lawn!
