Does fertilizer hurt new grass?
First off, fertilizer won’t kill your new grass when you follow the directions. It’s best to look for a starter fertilizer with a higher ratio of phosphorus than regular fertilizer. After the fertilizer has been completely absorbed into the soil, yes. It’s generally recommended to wait about 24-72 hours after a fertilizer application before letting your kids go back onto the grass and to also ensure your lawn is watered well before the kids go back to playing in the grass.Timing: Apply fall lawn fertilizer once between August and November, right before winter hits, six to eight weeks after the summer feeding.After fertilizing, avoid walking on your lawn for a day or two. This helps keep the fertilizer evenly distributed and prevents compacting the soil.
Can I put fertilizer on my new lawn?
It’s best to either fertilise before sowing any new grass seed and allow the granules to fully dissolve before sowing OR wait until the grass is fully established (6-8 weeks) before then applying a fertiliser. For granular fertilizer: Apply 1/4 inch of water (15-20 minutes with most sprinklers) immediately after application. This washes fertilizer from grass blades into the soil, activating the product. For liquid fertilizer: Wait 2-4 hours before watering. This allows the product to absorb through grass blades.Watering after fertilizing washes the fertilizer off the grass blades and into the soil, where it can get to work nourishing your lawn. It’s also important because if fertilizer sits too long without being watered in, it can burn the grass.
When should you not put fertilizer on your lawn?
Grass can only absorb fertilizer when it is actively growing. Turfgrass plants stop growing – become dormant – when the soil temperature is below 55°F or in the heat of the summer. Cooler soil temperatures also slow the bacterial action that makes some fertilizer nutrients available to the plants. Cool-season grasses begin greening up as soon as soil temperatures consistently reach 40–50°F. This can happen as early as late February in milder climates or late March in colder regions. Because they are adapted to cooler weather, these grasses respond quickly to increasing daylight and moderate spring temperatures.
What is the best fertilizer for new grass?
Many starter fertilizers contain a high concentration of both phosphorous and quick-release nitrogen to boost root and shoot growth at the same time.

How long does fertilizer take to affect grass?
How Long Does it Take Fertilizer to Work? Most fertilizers start showing results within one to five days after it’s been fully absorbed by your lawn. Slow-release formulas often take a bit longer, but you’ll still likely see a difference in your lawn’s health within a couple of weeks. Whether you’re repairing bare spots, overseeding an existing lawn or starting from scratch, you can generally expect grass seedlings to emerge within seven to 21 days when grown under proper conditions. It may take another three to four weeks of growth before grass is long enough to mow.At about 4 to 6 weeks after the seed germinates fertilize the lawn with a high quality turf fertilizer that is predominantly nitrogen. Once turf is 4 to 6 weeks old or older, nitrogen is the most important nutrient for a healthy, attractive stand of grass.
