Does Liquid Fertilizer Really Work?

The benefit of a fertilizer should be indisputable. Regularly at the time of the new lawn season, the fertilizer should be used so that the lawn is again in perfect health and receives optimal conditions for growth. Usually for this type of fertilizing resort to a granule.

However, the granules have significant disadvantages, which is why they are not useful to use in all conditions. For example, the granules are highly dependent on the weather, and in strong winds they are pushed off the lawn. The fertilizer is carried around and in the end, although part of the lawn is green, other areas remain bare and look very unsightly.

If you no longer want to use the granules, for example, a blue grain for the lawn, and prefer to try an alternative, then you can use a liquid fertilizer. This also provides the lawn and the plants with the necessary nutrients, but has decisive advantages compared to the granules.

Here you will now learn how to optimally treat the lawn with the liquid fertilizer to get a uniformly healthy lawn.

What is liquid fertilizer for the lawn.

An important ingredient in most lawn fertilizers is nitrogen. Nitrogen is important for plants to grow quickly and healthily. Liquid fertilizers and the granules do not differ significantly in structure. The ingredients are the same, although in the case of liquid fertilizer these are in the form of a solution or suspension.

Nutrients are thus present in liquid fertilizer in dissolved form and are applied to the lawn in this way. The liquid can either be poured over the lawn or sprayed.

However, the fertilizer should only be sprayed with the appropriate equipment. Otherwise, there is a risk that the lawn will be treated very unevenly by the fertilizer.

Depending on the product, the liquid fertilizer is applied to the lawn in a different way. Most fertilizers are offered in stores as concentrates. These must be diluted with water before application.

Sometimes there are also products that are connected directly to the garden hose. This is the simplest option, but it is not always ensured that the fertilizer is evenly distributed over the lawn.

Avoid overfertilizing

If you want to bring up the lawn particularly fast and healthy, then the suspicion is obvious that you could help the lawn a little with a particularly large amount of fertilizer. But when it comes to fertilizer, it’s not the sheer quantity that counts.

Especially with liquid fertilizer, there is a great danger that you will put too much fertilizer on the lawn. This is not necessarily harmful to the lawn, but it also has no benefit. The fertilizer seeps into the soil and ultimately you just spent more money than would have been necessary.

Therefore, you should be rather careful when applying the liquid fertilizer. What exactly is the optimal amount for your lawn you have to find out yourself and find a middle ground to proceed as resource-efficiently as possible and still provide the lawn with the necessary nutrients.

How is the liquid fertilizer applied to the lawn?

A big advantage of liquid fertilizer is that it is very easy to apply. You don’t have to think much about this, and ultimately just make sure you don’t put too much fertilizer on the lawn.

When choosing fertilizer, you should pay attention to the time of year when it is applied. Because at different times, the needs of the lawn also changes. If you are just starting the new lawn season, you must of course choose a product that is applicable in the spring. In the fall, you can then reach for a different fertilizer.

The first time fertilizing should be done in March. Here, temperatures are usually above freezing, so soil frost no longer occurs and the lawn thus slowly awakens from its winter sleep. Now is the time to provide the lawn with the necessary nutrients and apply the liquid fertilizer.

Some products have a cap that connects directly to the garden hose. Other products are available directly as a spray bottle. Here, the liquid fertilizer only needs to be sprayed over the plants or lawn.

The plants absorb the fertilizer either through the flowers or the roots. If you have plants with large flowers in your garden, then you will sometimes have problems applying the granules to the appropriate places. However, with the liquid fertilizer you can easily spray the leaves and the effect of the fertilizer will remain.

Tips for the application of the fertilizer

As with any other fertilizer, it is recommended that you apply the liquid fertilizer in a checkerboard pattern. To ensure that you distribute the fertilizer as evenly as possible, it is a good idea to start by spreading the fertilizer in one direction only. You can therefore first proceed horizontally and spray the entire area and then drive vertically over the area again.

Before applying the fertilizer, the lawn does not need to be scarified. Even without scarifying, the nutrients will be completely absorbed by the plants and you do not have to worry about the soil not being of perfect quality.

Watering is also not necessary. With granules, it may be beneficial if you lightly sprinkle the lawn, but with liquid fertilizer for the lawn, this is not necessary.

If you are unsure about the dosage, then you can use a rule of thumb. This states that one liter of the liquid mixed with water is sufficient to fertilize about 100 square meters of lawn. However, in the product instructions you should find more specific information about the amount for which the liquid is sufficient.

Advantages of the liquid fertilizer for the lawn

In order for the lawn to grow optimally, the application of a fertilizer is inevitable. Most soils are not provide the perfect conditions and therefore the liquid fertilizer lead the lawn must be applied to support the growth.

Unlike the granules, the liquid fertilizer has the advantage that it is immediately absorbed into the soil. Thus, its action is much faster than compared to the granules, which require a longer time to be absorbed into the soil.

Due to the rapid absorption of the liquid fertilizer, the nutrients are passed immediately. If the winter has disappeared quite suddenly and you were surprised by high temperatures in March, then you should not hesitate and use the liquid fertilizer. When it gets warmer, the lawn needs nutrients immediately and they are provided only by the liquid fertilizer.

Another advantage of liquid fertilizer is that its application is relatively accurate, even without additional equipment. In the case of granules, a spreader is indispensable for a good result. For the liquid fertilizer, on the contrary, only a garden hose is necessary, or if it is in a spray bottle, you do not need any tools.

Overall, the amount of work is very small. The lawn or plants do not need to be scarified and lawn sprinkling is also not necessary. Are you looking for a simple but effective method, then the liquid fertilizer for lawn is the best way to fertilize.

Disadvantages of the liquid fertilizer

When it comes to the effect of the fertilizer, it is not only the application time that is of great importance. In order to provide the lawn with the nutrients in the long term, the long-term effect is important.

Here, liquid fertilizers are said to act faster compared to granules, but the long-term effect is somewhat lower. To counteract this effect, there are special liquid fertilizers that have been optimized in terms of long-term effect. Thus, the duration of action has been extended at least to 50 days, which is considerable, but still slightly at a disadvantage compared to the granules.

Another aspect that should be considered when applying the liquid fertilizer on the lawn is the dosage. This is not always easy to determine and adhere to. However, in most cases, the product instructions clearly indicate the ratio in which you need to mix the fertilizer.


If you are looking for an easy way to supply the lawn with fertilizer and this should be done as quickly as possible, then the application of liquid fertilizer is the best option.

The fertilizer immediately provides the lawn with potassium and nitrogen. These nutrients are urgently needed especially at higher temperatures and the lawn will thank you by quickly shooting up and shining green.

So you can fertilize even a larger area of 100 square meters within 5 minutes.
