Buying Guide: Selecting the Best Fertilizer for New Grass
Choosing the right fertilizer for new grass depends on several factors. This guide highlights key considerations to help you pick the best product for your lawn’s needs.
Nutrient Ratio (N-P-K)
New grass requires a careful balance of nitrogen (N) for leaf growth, phosphorus (P) for root development, and potassium (K) for overall health. Starter fertilizers typically have higher phosphorus content, essential for establishing strong roots. For example, ratios like 24-25-4 or 20-27-5 emphasize phosphorus to benefit seeds and sod during germination.
Type of Fertilizer
Fertilizers come as granular, liquid, or spray forms. Granular fertilizers, like those from Scotts and The Andersons, provide a slow-release nutrient supply, while liquid fertilizers offer quick nutrient absorption. Choose liquid sprays for fast greening or granular for sustained feeding.
Application Method and Ease
Consider how you will apply the fertilizer; some come with easy-to-use sprayers, while others require spreaders. Liquid fertilizers with sprayers allow for more precise application but might need more frequent treatments.
Compatibility With Grass Type
Ensure the fertilizer is compatible with your grass species. Most starter fertilizers work broadly across grass types, but always confirm if the product is suited to warm-season or cool-season grasses.
Additional Ingredients
Some fertilizers include additives like iron for deep greening or humic acid to improve nutrient uptake and soil health. These extra components can enhance growth and lawn color but may also increase product cost.
Coverage Area and Lawn Size
Match the fertilizer coverage size to your lawn area to ensure you purchase the right amount. Larger bags are more economical for big yards, while smaller sizes suit smaller plots or testing new products.
Weed Control Features
Certain fertilizers, such as Scotts Turf Builder Triple Action, combine fertilizing with weed prevention, which may save additional lawn treatment steps when planting new grass.
