1. Watering
  • After the lawn is first hydroseeded, allow the mulch to dry before watering. (Usually dry within 6 hours or by the next day.)
  • Hydroseeded area should be watered twice daily, optimum is three times per day, in the morning and mid afternoon, and kept moist (not allowed to dry out) for 10 to 14 days to ensure optimum germination.
  • In cooler weather (Early Spring / Late Fall) please note if the hydroseed is extremely soggy in certain areas between watering sessions.  This may require shortening the watering periods of those areas. 
  • Skip days with substantial rain.
  • Watering in the evening should be avoided to prevent lawn fungus. 
  • When watering, do not over-water to the point that puddles are formed or run-off occurs.
  • Mow grass when height reaches 3 1/2 inches.
  • Set mower to cut at 3 inches so as not to burn the new grass by cutting too close to the ground, especially in hot weather. Leave grass longer for the first season to allow for root system to become established. 
2. Fertilizer and Weed Control
  • When your hydroseed is applied, it contains started fertilizer to maintain the new lawn for 3 to 4 weeks.
  • After 3 to 4 weeks, apply a starter fertilizer application according to directions on bag for amount per square foot. Recommender fertilizer should be 18-24-12 starter with 12% slow release.
  • After another 3 to 4 weeks, basic lawn food should be applied.
  • Apply lime in the fall. No weed control in fertilizer is recommended for the first year. Spot weed with a product such as "Weed Be Gone."
  • After lawn care is established follow a multi-step yearly fertilizer/weed control program or use a professional lawn care company.
