Step 1: Recall the methods of making a lawn:
A lawn can be made by seed sowing, dibbling, stolonising (planting stolons), turfing and sprigging.
These methods differ in cost and in the time they take.
Step 2: Compare the speed:
Seed sowing and dibbling need many weeks before the grass covers the ground.
Stolonising also takes time for the grass to spread.
In turfing, ready-grown patches of grass with soil are laid on the prepared ground.
The lawn is ready almost at once.
Step 3: Choose the method:
Turfing is the fastest, though it costs more.
Final Answer:
Turfing (laying ready-made grass turf or sods) is the fastest method of developing a lawn.
