Make a data chart on the soil report and divide it into sections of current conditions and requirements. Choose the right fertilizers according to their needs(because sometimes, you find soil pH too acidic but sometimes it becomes more alkalic). Don't use fertilizers till you aerate your lawn once again. 

Improve lawn drainage

Make your lawn sloppy towards the boundaries of the lawn. There are many lawn slope models that you can follow. You can also install a proper automatic drainage system under your lawn turf. 

Keep low down the current moisture of the soil till 30% is left in the soil. 

Least shady atmosphere

Keep your lawn away from the trees and shrubs shades. In many houses, people make wall fencing on tall heights. Because of these tall wall fencing, people face problems like less growth, moss, algae, and weeds on their lawns. 

Provide direct sunlight in the algae-affected area at least for 2 weeks. 

Aeration, Overseeding, and fertilization

After 2 weeks of daily direct sunlight(5 to 7 hours daily), now you need to aerate your affected area. 

In all the marking areas, aerate the lawn by using aeration machine or aerator tools(in short lawns). 

Now use the required fertilizers according to your soil need(based on the soil sample report). You can also add some pre-emergents with fertilizers. Now, mix everything well and level the soil surface. 

To increase some moisture in the soil, spray 1-inch water and wait for 2 hours. 

Your soil is ready for overseeding. Use high-quality pure seeds of the same grass you had on the rest of the lawn. Sprinkle all the seeds and cover them with the soil by using a plastic reck tool.

Using a sprinkler irrigation system 

The best way to irrigate your lawn automatically is to use sprinklers at the corners of the lawn. You can adjust them on multiple points and cover particular sections too. It may increase your cost but is very helpful in the long term.
