How Soon Do You Mow New Sod

How Often Should I Fertilize The Lawn – Quick Tips

Your new sod can be mowed when it looks like it needs mowing . When possible, use a walk-behind power mower, with the cutting height set high . Do not use a riding mower as it is too heavy and its powered wheels can tear up the new sod. After the sod has fully rooted , regular mowing can commence. For best results, never cut more than 1/3 of the grass blade per mowing and maintain sharp mower blades. Cutting frequency will need to be increased during the faster growing seasons of spring and fall. Grass clippings may be left on the lawn to return nutrients to the root zone.

What Is Lawn Fertilizer

Think of lawn fertilizer this way: No matter how many glasses of seltzer you drink, you cant live on ityou need to tuck into a few good meals each day, too. Your lawn is just the same. As much as it needs water, it also needs additional nutrients to survive, and lawn fertilizer supplies those nutrients.

What Do The Letters Npk On The Fertilizer Bag Mean

Those letters stand for the nutrients nitrogen , phosphorus , and potassium . The numbers you see on the bag let you know the percentage of the N, P, and K thats in the bag. Heres why it matters: Nitrogen greens up your grass and helps it grow, phosphorus stimulates root growth and helps seeds sprout, and potassium helps your lawn withstand drought and disease. The highest number for lawn fertilizers will usually be the Nafter all, growing green grass is the ultimate goal, right?

When To Fertilize Cool

The best time to fertilize cool-season grasses is in the spring and fall when theyre growing most vibrantly.

Spring: apply fertilizer after the last frost when the grass thrives again, between April to June, depending on your location.

Fall: apply fertilizer just before the trees drop their leaves, from late August to October, depending on your location. Fertilize well before the first frost date, as you dont want to encourage your grass to grow in time for frost to kill it.

If youre using organic fertilizer like compost and only want to fertilize once, fertilize in the fall. The extra compost will help shelter your grass and the soil over the winter.

It also gives the beneficial microorganisms in your grass time over the winter to break down the organic matter into nutrients. This gives your lawn a head-start come spring.

If youre fertilizing twice a year, apply a light amount of fertilizer in the spring and a heavier fall.

Dont fertilize in the summer, especially when the grass has gone brown. The grass is fine. Feeding synthetic fertilizer will not make it turn green. Instead, force-feeding it nitrogen when its dormant is just going to stress it out and could even kill your lawn.

When To Fertilize New Grass: Best Fertilization Schedule For A New Lawn

Keeping your grass green and healthy doesnt have to be all that difficult. Unfortunately, it does require that you spend at least a bit of time on lawn maintenance, which means mowing, seeding, fertilizing and aerating as needed.

All of these factors become especially important when planting new grass, but the problem is that the majority of people are fairly clueless when it comes to deciding how often and when their new grass should be fertilized. With this in mind, we have produced this handy guide to tell you everything you need to know about fertilizing new grass.

If Your Lawn Was Laid In Autumn

The soil is still warm and hopefully the weather is mild so your turf will be working hard to put its roots down.

Its important at this time of year that the sward doesnt get too lush.; Soft new growth is more susceptible to disease in autumn than at any other time.

The pre-turfing fertiliser you worked into the soil before you laid your lawn should be enough to keep the plants going.; If you didnt get around to using it, apply an autumn-winter lawn feed 4-6 weeks after turfing.; But be careful! It MUST be low in nitrogen.; You dont want to stimulate fast-growing but weak leaves.; This feed is for the roots.; Nothing else.

Lawn Starter Fertilizer Vs Regular Fertilizer

Would you feed a newborn baby a slice of pizza? Of course you wouldnt. And obviously, thats a ridiculous question.

Because you know that babies have special needs. In order to grow and develop in the beginning, it is vital that they receive the nutrients they need from their mothers milk or baby formula.

Heres the thing, though. A lot of people do the equivalent of feeding a newborn a slice of pizza when they try to fertilize new grass.

How so?

They use regular fertilizer instead of starter fertilizer.

Both can provide plants with valuable nutrients, but they are not interchangeable. The nutrients they contain differ, and plants need each type at different stages of their life cycle.

Regular fertilizer contains a mix of nitrogen, potassium and phosphorus at a 1-2-1 ratio. Thats great for established plants, but not so wonderful for seedlings.

In fact, the main ingredient in most starter fertilizers is phosphorous, which makes grass seeds much more likely to germinate and sprout. Many also contain quick-release nitrogen to assist in germination and the development of the seed. In other words, they are specially formulated for seedlings.

So, when do you add starter fertilizer to your new turf?

Choosing The Right Fertilizer

How Often Should I Fertilize My Lawn?

What this means is, when trying to grow new grass, you need to choose a special kind of fertilizer known as a starter because fertilizers for new grass and fertilizers for established grass dont have the same composition.

The three nutrients we mentioned, nitrogen, phosphorous and potassium, should all be present in starter fertilizer, but may not be present at all in regular lawn fertilizer.

When buying fertilizer, you will often see the ratio of these three nutrients written on the packaging, usually in this order.

Regular lawn fertilizer usually has a ratio of something like 30:0:0 or 27:3:3 since established grass doesnt require phosphorous or potassium. However, with starter fertilizers, you are more likely to see ratios like 21:22:4, which will help your new grass get off to the best start.

Regular fertilizers are also said to be slow release because they dont make the nutrients available all at once. This way, they keep your lawn fed for a longer period.

However, starter fertilizers should be quick release, meaning once you have applied the fertilizer, the nutrients are available for the new grass right away.

To find the right fertilizer for your needs, you should first test the soil and then choose one that is appropriate for your soil conditions.

Which Fertilizer Is Best For Your Lawn

The fertilizer category mainly consists of two things organic and inorganic fertilizer. The other thing you will hear about will be slow-release and quick-release fertilizer. Now lets take a deep look into these categories:

  • Organic; These types of fertilizers consist of natural ingredients made from plants and animal waste, which provide nutrients and essential components to the soil. These fertilizers are environmentally friendly and sustainable for the lawn. This fertilizer promotes the growth of microbes and fungi which releases nutrients slowly to the soil.;

These fertilizers give the soil strength to fight harmful insects and pathogens and it also helps the grass to access nutrients from the soil.;

  • Inorganic Inorganic or synthetic fertilizers are fertilizers that are made artificially in factories with the help of chemicals and other processes. These fertilizers give a boost to your grass by releasing the nutrients very quickly.

The downside to inorganic fertilizer is that it can harm the environment by leaching, in which the fertilizers are washed away by rain or irrigation below the level of roots.;

The other con of synthetic fertilizer is that if you rely too much on this fertilizer then it makes your grass dependent on the fertilizer itself and cant survive without it.

What Temperature Is Best For Fertilize Lawn

The very best time to fertilize your lawn is in the spring, when the soil temperaturenot the air temperaturereaches 55º Fahrenheit. Youll know when the soil warms up to 55º because the lilacs will begin to blossom and the grass will start growing. Or, buy a soil thermometer and check the temperature at any time.

Know What Type Of Grass Is On Your Lawn

To fertilize your lawn properly, you need to know if you have warm or cool-season grass growing on your lawn. Which category a species of grass belongs to depends on its growing cycle. Some grasses are dormant during the fall, spring, and winter months.;

These are cool-season grasses, which include:

  • Tall fescue
  • Perennial ryegrass
  • Kentucky bluegrass

These species are most common in regions that experience large fluctuations in temperature. In the US, that means roughly the upper two-thirds of the country. In the middle, theres a transition zone where both types are common. Warm-season grasses, which grow actively during the summer and early fall, are most common in the southern half.

  • Centipede grass
  • Zoysia grass

Whatever overall type you have growing on your lawn, your grass is likely a blend of two or more species chosen based on whats right for your area, whether thats excessive shade, sun, or foot traffic.

;So, assuming you have the right grass for your situation, you can plan your fertilizing schedule around what type of grass you have.

How Often Should I Fertilize My Lawn? (The Surprising ...

Believe it or not, you can over-fertilize your lawn and end up with the aftereffects on more than just your lawns.

In the state of New York, for example, over-fertilization has been the cause of harmful algal blooms in bodies of water. Besides this, it:

  • Causes excess fertilizer to leach through the soil faster than the roots can absorb it. Instead, it ends up in the water table and clogs waterways with vegetative growth
  • Triggers excessive mowing
  • Causes weak, overgrown turf, which is susceptible to pests
  • Contributes to thatch build-up

And that’s not how anyone wants to leave their lawn. Especially not when the alternative cultivating a rich and thriving blanket of green takes just a little mindful planning.

What Nutrients Are in Lawn Fertilizer?

There are three primary minerals in fertilizers for enhancing grass health: nitrogen, phosphorus and potassium.

On packages, youll notice most companies use a ratio, otherwise known as;NPK. For example, a 20-5-5 ratio means 20 percent nitrogen, 5 percent phosphorus, and 5 percent potassium.

Different fertilizers will contain various ratios designed for specific uses and types of grasses.

How Do They Help New Grass?

Fertilizer provides your soil with the right minerals that make your lawn grow fast, lush and green.

The right fertilizer will improve the overall health and appearance of your lawn and will help protect it from drought and burning.

Organic Vs Synthetic Fertilizer

While you may be tempted to pick up a bag of synthetic fertilizer at your local hardware store, they come with a ton of disadvantages to your lawn, your health, and the environment.

Synthetic fertilizers dont remain in the soil very long , require extra care to avoid nitrogen burn, encourage erosion and soil compaction.

They also rob the soil of organic matter and beneficial microorganisms and have negative health impacts on you, your family and pets, and any aquatic life in your nearby groundwater.

Organic fertilizer will last year-long, wont cause nitrogen to burn, aerate the soil, prevent erosion, add organic matter and support beneficial microorganisms, and are better for human and environmental health.

Suppose you want a low-maintenance lawn, transition to an organic lawn using organic fertilizers. The transition will require a few years of nurturing, but youll love it in the end.

I recommend reading Paul Tukeys essential guide, The Organic Lawn Care Manual, for a complete schedule for transitioning painlessly to organic.

When To Fertilize New Grass

WHEN and HOW to FERTILIZE your lawn

It is important to make sure that your soil has the appropriate nutrients for new grass seed prior to dispersing the seed itself.

So, after preparing your soil for seed or sod, the last step before planting is to fertilize the soil with a starter fertilizer. This can be done before you lay seed or sod, or at the same time.

After you apply starter fertilizer, dont reapply it. The ratios of nutrients can actually be harmful and burn established grass. I recommend using a traditional, nitrogen-rich organic fertilizer 6-8 weeks after planting new grass.;

While you may be eager to fertilize again to encourage growth, fertilizing too often is harmful. It can burn your grass, leach into the water table, and more. Its important to wait a minimum of four to six weeks before another application of fertilizer, and I recommend 6-8 weeks.;
