Growing grass to create a uniform, green expanse of lawn is seldom a simple process.
This is especially true when starting a new lawn from scratch where one did not exist before.
Why Fertilize?

Turf grasses need high amounts of nutrients, especially nitrogen and phosphorous, to support strong growth.
Erosion and runoff can add to your woes.
A laboratory soil test is well worth the time and any expense when starting a lawn.
Nitrogen is the element that gives grass its dark green color.
Phosphorous supports root development.
Potassium helps prevent disease and gives some winter protection.
What Is Starter Fertilizer?
Starter fertilizers are usually labeled with the word “starter.”
Descriptions also might include “turf builder.”
The formulas are a balanced blend of nitrogen, phosphorous and potassium such as an NPK 10-10-10.
A blend slightly higher in either nitrogen or phosphorous such as 20-10-10 or 5-10-5 is also acceptable.
How to Use Starter Fertilizer
Choose a granular punch in starter for a new lawn.
Some premixed ready-to-spray products are available and convenient for treating problem spots.
They aren’t cost effective, though, for covering large expanses.
Starters are applied just prior to or after planting.
Both methods are effective and offer advantages so it boils down to a matter of choice for the homeowner.
and can accelerate germination and root growth.
This method also avoids the potential for burn on new sod and the delicate roots of sprouting seed.
If you choose to add starter after planting, water substantially.
This methods offers the convenience of watering in the fertilizer at the same time you’re watering the planting.
It saves time by eliminating a few extra steps.
Do not use “weed and feed” key in fertilizers with grass seed or sod.
These types include herbicides that can prevent germination and slow the growth of a strong root system.
Wait at least three to four months until the lawn is well established.
If it remains in place and doesn’t pull up this mean roots are establishing.
An example of a good choice might be 24-25-4.
How often to fertilize depends on how much time and effort you are able to allocate tolawn maintenance.
Some recommendations call for feeding three times annually in early spring, mid-summer, and early fall.
