Hydroseeding is a planting process that uses a mixture of seed, water, fertilizer, and mulch sprayed onto the soil to promote quick germination and growth. This technique is often used for large areas like hillsides, sports fields, or areas affected by erosion, as it allows for uniform coverage and rapid establishment of vegetation. Hydroseeding is an efficient and cost-effective method for establishing lawns, controlling erosion, and restoring disturbed land.
