Well, if you fail to choose the right lawn fertilizers, it will be nothing but a disaster.

You must see that there are hundreds of types of fertilizers available in the shop. The producing companies launch so many types because different fertilizers work for different reasons. Where some are good for growth, and some work to get rid of dry patches and other lawn diseases.

So, whether it is homemade lawn fertilizers or store-bought ones, it is essential to choose the right lawn fertilizers. But many people, especially beginners, fail to choose the right fertilizer that their lawns actually need. And that’s why I am here to share with you everything you need to know about choosing the right fertilizer for the lawn. So, don’t miss a single word if you are concerned about this fact.

Is It Necessary to Choose the Right Lawn Fertilizers?

choose the right lawn fertilizersFertilizer is not a silly fact, especially for your lawn. Some people mistake it as just a mandatory part of lawn maintenance, and it’s okay to use any fertilizer they find in the store. I’m afraid I have to disagree with them, in this case, anyway.

Basically, fertilizer is not mandatory for your lawn, and you should use it for the wellness and healthy growth of the grass. But you cannot possibly have a lush green lawn without regularly fertilizing it. Also, most of the time, the lawn soil doesn’t have enough nutrients that the grass needs. So, if you use needful fertilizer, you will be able to fill up the needs.

So, it is essential to find out which nutrient the soil doesn’t have in sufficient amounts and ensure to use of fertilizers rich in that particular nutrient. Suppose your lawn soil has sufficient Potassium, and you are applying a potassium fertilizer to it.

Remember that excessive amounts of nutrients can also cause major problems as well. It even can just leave the lawn dead completely.

Also, your lawn may have different diseases and problems. And you need to choose the right fertilizer to create it. That’s why it is always very essential to choose the appropriate fertilizer for your lawn.

What Does The NPK Number Mean?

NPK, choose the right lawn fertilizersIf you check out the packets of some lawn fertilizers, you will find a ratio of numbers. It is the NPK number. Knowing the NPK ratio is a must to choose the right lawn fertilizers. Indeed, the variation of the fertilizer is entirely dependent on this number.

However, the NPK number actually refers to the ratio of Nitrogen, Phosphorus, and Potassium. And these three nutrients are the essential things plants need. Here, the NPK number refers to the percentages of these three nutrients in the fertilizer.

If the NPK number of fertilizer is 16-8-12, it means the fertilizer has 16% of Nitrogen, 8% of Phosphorus, and 12% of Potassium. And if you want to know the amounts of those nutrients in the fertilizer, you have to multiply the ration number by the product weight. That’s simple; it is to understand the NPK number in a fertilizer.

How to Choose the Fertilizer With the Right NPK Number?

NPK lawn fertilizersYou know what the NPK number refers to. But the question is, how can you be so sure about which number is appropriate for your lawn. Well, for that, you should go for a lawn soil test. The result will tell you what nutrients your lawn soil needs.

However, you can also understand it by checking the condition of your lawn. Generally, Nitrogen works well for the growth of the grass and makes them greener. Phosphorus is essential for root growth. And your lawn soil will need Potassium to fight different lawn diseases and also for recovery.

So, you have to check which ingredients are essential for your lawn. And then find a fertilizer that contains a better amount of that specific ingredients. For example, if you want to make your lawn greener, you have to apply fertilizer rich in Nitrogen. In that case, you can go with one that has the NPK number 16-4-8. It has a better amount of Nitrogen, so that this fertilizer will be helpful in this case.

Appropriate NPK Ratio for New Lawn

According to the professional, you should choose a fertilizer that is low in Nitrogen and high in both Potassium and Phosphorus if you have a new lawn. It’s because Potassium and Phosphorus are quite essential for the new lawns as they can easily get affected by diseases, and the roots should have better growth.

Appropriate NPK Ratio for Unhealthy Lawn

If you think that your lawn is not healthy, you should select the fertilizer with the right NPK. In this case, the fertilizer should have more Nitrogen than the other two ingredients. Nitrogen is essential to revive the lawn from its unhealthy condition. The level of Potassium should be slightly higher in this case as well.

Appropriate NPK Ratio for Heat Stressed lawn

In summer, heat stress is the most common issue, so you should choose the right fertilizer. In this case, Nitrogen and Potassium are essential, and the rate of Phosphorous should be lower. The NPK ratio like 12-4-12, 16-4-8, etc., are good examples of this problem.

So, the best way to choose the right lawn fertilizers is to choose the fertilizer with the appropriate NPK ratio. Once you know what the soil is supposed to have, you can easily choose the appropriate fertilizer for your lawn if you know everything about the NPK ratio. Aside from this, you also need to know about the types of lawn fertilizers.
