You should use a different lawn fertiliser in autumn that you would use when you are preparing your garden in spring. We recommend using either Miracle-Gro EverGreen Autumn Lawn Care or Miracle-Gro EverGreen Premium Plus Autumn & Spring Lawn Food.
Fall Fertilizer Timing
For the majority of cool-season lawn owners, apply fertilizer anywhere from September through early November. The further north you garden, the sooner you'll feed your lawn. Fine-tune the timing for your locale by talking with your local extension service or garden center.
As a general rule, warm-season grasses will need four times per annum feeding. Apply the first dose when you see new growth starting - this should be done around March/April time frame for most areas with mild winters which helps their young leaves grow healthier faster than if they were left untreated all season long.
Apply a nitrogen-rich fertilizer.
If you want your lawn to look better and be healthier, fertilize in the fall.

You should fertilize your cool-season lawn in fall and/or spring, and fertilize your warm-season lawn in mid-to-late spring and/or summer.
Recommended for root development of all types of plants. Normally is selected for feeding trees and landscaping plantings. Recommended for root development of all types of plants.
While this fall lawn fertilizer dose is important, an application at the end of October or early November is essential. At that time, apply a fertilizer with a formula of 13-25-12. The push of phosphorus will stimulate root growth through November and even into early December.
When To Fertilizer Your Lawn in the Fall. The best time to apply your last fertilizer application is between August 15 and October 1. Ideally, your last lawn feeding should take place six to eight weeks before the average first frost in your area.
Timing: Apply fall lawn fertilizer once between August and November, right before winter hits, 6 to 8 weeks after the summer feeding.
“Once spring arrives, your lawn will quickly tap into these nutrients for a beautiful burst of green. In fact, a lawn fed twice in the fall will stay green longer into winter and be the first to green up in the spring.”
Cool-season grasses such as Kentucky bluegrass, perennial ryegrasses and tall fescues, including Kentucky 31 fescue, grow most vigorously during the cool temperatures of late summer and early fall.
You should fertilize your lawn a day or so after a light rain or using a sprinkler. This prevents the application from being washed away. The moisture gets your soil damp and ready to receive nutrients. Do not apply fertilizer before or after heavy rains.
Ideally, you'll want to mow and rake before fertilizing, so that excess lawn waste is removed and the fertilizer will have an easier time reaching the soil.
Lawn Feeding Calendar
During the growing season from spring through fall, your lawn, whether established or newly seeded, will perform best when fed four times, with each feeding applied 2 to 3 months apart.
Its 30:30:30 nutrient ratio makes it good for almost any stage of plant growth. The design of the formula uses nutrients that provide strength to the plant, as well as, lush green growth.
It is aimed at the nutrition of various crops, grown on various soil types, especially when there is a distinct need for potassium. It is applied in the basic or pre-seeding cultivation of land, by even distribution on the entire area or locally in rows.

Arizona's Best Starter Fertilizer has an N, P and K ratio of 6-20-20 and is designed to help grass and sod develop roots and mature stems before top growth begins. Either apply before sod is laid or immediately after seed is sown, and at the time of planting for flowers, trees and shrubs.
Overseed your lawn 6-8 weeks before the first hard freeze.
Fall is a good time to seed cool season grasses and it will give the lawn a boost in the spring by preventing excessive loss of grass during the winter. If the lawn is too big to seed by hand, consider using a rotary spreader.
Choosing the Right Seed
The best grass seeds for overseeding include our Blue Wave bluegrass and Heat Wave fescue, which have excellent germination rates.
Why It's Best to Reseed in the Fall. The fall allows grasses to establish before winter sets in. Two months before the first frost is the best time. Fewer weeds and fewer active lawn diseases occur during the fall therefore your grass will not have to compete for access to sun and water.
