The answer to 'how much does seeding cost' is that the cost can vary widely depending on several factors. In general, seeding a lawn can range from a few hundred dollars for a small DIY project up to several thousand dollars for a large professional job.
The main factors that influence the cost of lawn seeding include the size of the area, the type of grass seed used, whether soil preparation is needed, and if the work is done by a professional landscaper or as a DIY project. DIY seeding can be more affordable, but requires more time and effort on the homeowner's part. Professional seeding typically costs more but provides a higher quality, more reliable result.
