As of September 2015, some good fertilizers for new grass are Scotts Turf Builder Starter Brand Fertilizer and Ringer Lawn Restore II Fertilizer. Both average more than 4.5 stars in online retailers' five-star users' rating systems.
Scotts designed its starter fertilizer to improve lawn's ability to absorb water and nutrients. The phosphorus component helps establish strong seedlings by anchoring roots fast. Reviews at The Home Depot website say that the fertilizer works quickly, even in poor soil. Regular watering is necessary at the start.
Ringer fertilizer works on many types of lawns, including young grass. The product helps new seeds establish root systems. Reviewers on the Safer Brand website report that Ringer works well during any season. The fertilizer spreads evenly and easily.
