Lawn Care Treatment in Early Spring

In Early Spring, apply a “Pre-emergent” Weed preventer such as a Pre-Emergent Crabgrass and Weed killer, ensuring the ground has reached 55 degrees or warmer. If any colder, the treatment will not be effective.

Lawn Tips for Spring

In the spring, your lawn is just starting to wake up from its winter slumber. Now is the time to give it a boost of nutrients to help it grow strong and healthy. A good spring fertilizer will contain a high level of nitrogen.

When buying a fertilizer high in Nitrogen, look for the “N” level percentage; this will help your grass grow quickly and fill any bare spots.  Most fertilizers marked as Weed & Feed will be suitable for Spring applications.

Best Lawn Fertilizer for Summer

The summer is a time of growth for your lawn. It will need regular fertilization to keep up with the demands of the heat and sun. A good summer fertilizer such as Scotts Summerguard will contain a balanced blend of nitrogen, phosphorus, and potassium. This will help your grass stay green and healthy all summer long. 

Best Lawn Care in Fall

As the days get shorter and the nights get cooler, your lawn will start to slow down its growth. But it’s still important to fertilize it in the fall. A good fall fertilizer, such as Scotts Winterguard, will contain a high potassium level.

This will help your grass prepare for the winter by strengthening its roots and making it more disease-resistant.

Winter

In the winter, your lawn will go dormant. It will need very little fertilizer during this time. But if you live in an area with harsh winters, you may want to apply a light fertilizer in the early spring to help your lawn recover from the cold.

This seasonal lawn fertilizer program will keep your lawn looking its best all year.


What Do Those Fertilizer Numbers Mean?

First, it helps to understand Fertilizer Designations on each bag so that when buying fertilizer, you will know which formula to purchase – and when to apply it to your lawn.  

There are three main elements in lawn fertilizer: nitrogen, Potassium, and Phosphorus, and below is a photo of how the Fertilizer Elements (by percentage) appear on the bag:

These element symbols are N (Nitrogen), P (phosphorus), and K (Potassium or Potash), and the percentage of each element will always be listed on the fertilizer bag in this same order. N-P-K.

The numbers printed on the fertilizer bag above, for example (5-10-10), indicate a percentage of 5% Nitrogen (makes lawn green), 10% Phosphorous (builds healthy roots), and 10% Potassium (maintains good roots and prevents stress).

Knowing the elements indicated for each fertilizer element, you can select the best fertilizer per season. 

Note:  If you prefer to buy a lawn care fertilizer plan without wading through the fertilizer elements for each season, check out the package below from Scotts.

* Water your lawn thoroughly after fertilizing.

Frequently Asked Questions (FAQ)

When is the Best Time To Fertilize a Lawn?

The best time to fertilize your lawn is “while it is growing”.  No matter what type of grass you may have, lawns require nutrients most, while they are in the growing stage.

For northern cool-climate grasses apply fertilizer in the spring and fall, and for warm-climate grasses, you should apply fertilizer in the late spring or in early summer.

What is the “Best Way” to Apply Lawn Fertilizer?

The two Best Ways to apply lawn fertilizer are to use a “Broadcast spreader” or a “Drop spreader” application.

Method #1:  Broadcast Fertilizer Spreader

A broadcast spreader is the most common method of applying fertilizer to your lawn. To broadcast apply fertilizer, you need a broadcast spreader, which projects fertilizer with a fan wheel distributing fertilizer in a broad path up to 10 Feet wide.

Broadcast spreaders come in various sizes so that you can choose the right size for your lawn.

Our top-rated broadcast spreader is Scott’s Elite Spreader which is suited to hold 20,000 square feet of lawn fertilizer.

To use a broadcast spreader, fill it with fertilizer and walk back and forth across your lawn, overlapping each pass by about 50%. This will ensure that the fertilizer is evenly distributed.

Method #2:  Drop Application Fertilizer Spreader

A Drop Fertilizer application is a more precise method of applying fertilizer, usually preferred by those with smaller lawns.

A drop spreader feeds fertilizer directly to the lawn below the spreader, vs. a wide path broadcast spreader which may not be suitable for small or sectioned-off lawns.

Drop spreaders come in various sizes and styles, and again you choose the right size for your lawn size.  If you prefer to buy a drop spreader, we like the no-nonsense Miracle-Gro drop spreader.

Fill a drop spreader with fertilizer and walk back and forth across your lawn, placing the fertilizer directly on the grass. This method is best for small lawns with many obstacles, such as trees or shrubs.

No matter which method you choose, it is important to read the instructions on the fertilizer label carefully. This will ensure that you are applying the correct amount of fertilizer and that you are applying it safely.


What Mistakes Should Be Avoided When Applying Fertilizer?

Here are some Mistakes You Should Avoid When Applying lawn fertilizer:

Mistake #1: Over-fertilizing is people’s most common mistake when applying lawn fertilizer. Too much fertilizer can actually damage your lawn and make it more susceptible to weeds and pests.

Mistake #2: Applying fertilizer on a windy day can blow the fertilizer away, resulting in uneven application.

Mistake #3: Applying fertilizer on a hot day can scorch the grass.

Mistake #4: Not watering your lawn after applying fertilizer can prevent the fertilizer from being absorbed by the grass.

Mistake #5: Not wearing gloves and eye protection when handling fertilizer can irritate skin and eyes.

By avoiding these mistakes, you can ensure your lawn gets the nutrients it needs without damaging the lawn.
