Can I put too much fertilizer on my lawn? There is the idea of “too much of a good thing,” and that definitely applies when it comes to fertilizing your lawn! Applying too much fertilizer to your lawn will cause the nitrogen and salt levels in the soil to increase rapidly, which can damage or even kill the grass.
Apply fall lawn fertilizer once between August and November, right before winter hits, 6 to 8 weeks after the summer feeding.
The best time to make late fall applications of lawn fertilizer is typically in November or the very beginning of December when the grass stops actively growing or has slowed down to the point of not needing to be mowed.
Depending on the level of damage done to your grass, you may be able to reverse the effects of fertilizer burn and help your lawn grow back lush and green. The important thing to remember when fixing fertilizer burn is that you need to reduce the amount fertilizer left in the soil.
Fertilizer and Water
A day or two before applying fertilizer, water your lawn thoroughly. After grass dries, apply fertilizer. Then lightly water again. This second watering is vitally important, because it washes fertilizer off grass blades and into soil.
Excess salt from fertilizer can build up in grass, scorching it and turning it brown. Your lawn might have this “fertilizer burn” if brown spots appear one to two days after fertilizing the lawn and the spots follow the pattern of where you applied the fertilizer.
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.
If done too early you could be inviting damage from the winter weather, such as snow mold. The best time to fertilize can depend on the climate, but typically September and October are usually the best months to apply fall fertilizer.
The November application also provides for early spring green-up without excessive top growth. Simply put: a beautiful green lawn with less mowing. But applications of fertilizer in late winter or early spring are converted directly to top growth.
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. Aerating your soil before fertilizing can also help; the best times to aerate are when your grass is actively growing, such as in spring or early fall.
Watering after fertilizing washes the fertilizer off of 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 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.
Yes, over fertilized plants can recover with proper care. To help them recover, you should flush the soil with water to remove excess nutrients. Adjusting the watering schedule and providing adequate sunlight can also aid in the recovery process.
Remove any severely damaged leaves. The best way to solve the problem of over-fertilization is to leach excess nutrients from the soil by using watering to slowly flush out the pot.
Fast-release synthetic lawn fertilizers work within 24 to 48 hours after application. Slow-release fertilizers work more slowly, but they are less risky to use. Synthetic slow-release products work in 2 to 5 days, while organic slow-release versions work in 2 to 6 weeks.
Fall is the best time. The autumn season comes with a mix of warm soil and cool air, perfect for planting grass seed and allowing time for new grass roots to develop before winter sets in. It is also a good time to fertilize to build stronger, deeper roots for winter, resulting in a thicker, greener lawn next spring.
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.
Contrary to popular opinion, fall is the best time of the year for lawn care. Fertilization, weed and thatch control, establishment of new lawns, and renovation of poor quality lawns should be done over the next few weeks. Your most successful seeding time is right around Labor Day.
When is the Best Time to Overseed? Late August to mid-October is the perfect window for fall overseeding. Mother Nature has it figured out, after two million years of overseeding the prairies, we follow her calendar. In their natural growth cycle, grass plants form seed heads and re-seed themselves.
The first thing to know about fertilizer is the formula. It is represented by three numbers, such as the most common 5-10-5. *Note: What these numbers represent are: nitrogen-phosphorus-potassium. Early fall fertilizers should be a 20-8-8 formula, while a late fall fertilizer application might require 13-25-12 mixture.
The best fertilizer to apply to a lawn in fall is high in nitrogen, especially if you have a cool season grass in your yard. Aim to apply one pound of nitrogen per 1,000 square feet of lawn.
Consistent watering is crucial in turning your brown, lifeless lawn into a vibrant carpet of rich green. Grass seed must have consistent moisture to germinate and establish healthy roots, so respect this critical step. Water your lawn daily so the soil stays consistently moist. If needed, water twice a day.
There is no way to revive dead grass, but you can keep brown or yellowing grass from dying out. The best way to revive dehydrated grass is to offer moisture as needed.
