When seeding and mulching to establish vegetative cover, the question arises: how much mulch should you use? The answer is, “it depends.” Ideally, you should aim for about 75% ground cover.

If you use too little, both the seed and the soil will lack protection from erosion, and moisture preservation will be compromised. On the other hand, if you use too much, the seed may struggle to germinate or reach sunlight. It is crucial to ensure that some soil is still visible through the mulch. Moreover, straw mulch, specifically from wheat, oat, barley, or rye, is preferable over hay.
