Erosion control measures - hydroseeding

Hydroseeding typically consists of applying a mixture of wood fiber, seed, fertilizer and stabilizing emulsion (tackifier) with hydromulching equipment to temporarily protect exposed soils from erosion by wind and water. This practice is suitable for steep slopes, stockpiles, large land areas and land that will be re-disturbed following an extended period of inactivity.


  • Provides temporary erosion protection prior to germination and seedling establishment
  • Suitable for hard to reach areas (e.g. steep slopes and stockpiles)
  • Relatively fast operation, covering large areas
  • Cost-efficient method of vegetating hard to reach areas, as it allows application of seed, fertilizers, mulch and tackifiers


  • Broadcast and drill-seeding are more efficient than hydroseeding for accessible areas with better soil conditions
  • In coarse and/or rocky soils, seed may be caught up with mulch on surface and become dried out (reduced germination), requiring seeding application prior to mulch and fertilizer
  • Mechanical damage and drying of seeds means higher seeding rate is required compared to conventional broadcast or drill seeding methods
  • Cannot be done during periods of heavy rain, strong winds or frost

Please note: Mulching and tackifier rate and type must be suitable to provide adequate erosion control prior to vegetation establishment, otherwise additional mulch application may be necessary.
