What Are The Advantages Of Using The Best Liquid Lawn Fertilizer?

1. Ease of Application

The majority of the best liquid lawn fertilizers can directly be connected to a garden hose for simplified application. Other types of solution-based fertilizer can be applied through an irrigation system and some through a pump sprayer. Whichever way it is applied, solution-based fertilizer provides uniform and consistent lawn food distribution.

2. High Concentration

You will also benefit from the high concentrations of liquid fertilizers that come in smaller packages. Subsequently, you can save on money compared to the granular amounts you might need for the same coverage in sq ft. Additionally, the high concentration enables you to dilute your solution-based fertilizer for your custom applications.

Further to adjusting the concentration, this type of fertilizer allows you to choose the best liquid lawn fertilizer concentrate suitable for your grass. In most cases, the best liquid lawn fertilizer should have a higher application initially, with gradual reductions after that during growth periods.

3. Fast Acting Nutrients

Liquid fertilizer also provides the benefit of quick absorption through the surface grass leaves and the roots. Considering that solution-based grass feed is delivered through water, you will be able to water your grass while providing lawn food. This fast absorption is unlike the granular lawn fertilizer that takes time to take effect and is not soaked up by leaves.

How Do You Apply Liquid Lawn Fertilizer?

At this point, you already know that liquid fertilizer can easily be applied through a hose or an irrigation system. Moreover, it is important to follow the manufacturer’s recommendation on how best to apply your select liquid fertilizer. Due to high concentrations of liquid fertilizer, always make sure you shake ready-to-spray products and alternatively properly dilute them to avoid burning your grass.

In cases where a product doesn’t have a sprayer attachment for a hose, you can also apply a hose-end sprayer for easy spraying using a garden hose. As you fertilize your lawn, always start from the furthest end and finish at the spigot to turn the water off without stepping on the fertilized lawn sections. Overall, the irrigation method is best for fertilizing your lawn because it evenly applies liquid fertilizer and eliminates the possibility of stepping on covered areas.

What to Consider Before Purchasing the Best Liquid Lawn Fertilizer

1. Test your soil

Before buying a liquid fertilizer, it is always prudent to know what your soil has and doesn’t have. The only way of knowing how much fertilizer to apply is through a soil test that you can easily do yourself, thanks to the self-use testing kits available at most garden centers. Additionally, nitrogen fertilizers mainly have nitrogen, phosphorus, and potassium, commonly known as N P K.

Subsequently, a soil test will adequately indicate the availability of the three nutrients in the soil and at what amounts. Depending on the percentage concentration of each of the three nutrients, you will, in turn, be able to choose the perfect solution-based dressing. Thus, even as you aim to make your soil rich for a green and healthy lawn, soil testing helps establish the right amount of fertilizer for your lawn care.

2. When Do you Apply Liquid Fertilizer?

Furthermore, you need to know when to apply lawn food depending on the seasonal variations. Usually, you will find directions on fertilizer packs on when to apply, depending on the manufacturer. In addition, below are some other useful tips on the consideration of when to apply.

If you choose a fertilizer for a single annual application, you should consider applying it before the late fall and winter for optimal nutrient absorption before the cold season. For a bi-annual fertilizer, you can consider two applications that will feed your grass through the winter and after. Across the different seasons, it is recommended that you apply a smaller amount of this fertilizer during spring.

You can start applying for spring and summer lawn food during spring as you progressively add smaller applications every few summer weeks. However, it would help if you were careful when doing peak summer applications when the conditions are very humid and hot. Instead of helping achieve green growth, fertilize liquid might harm your grass during peak summer.

Additionally, there are organic liquid fertilizers that are safe for application during summer. Alternatively, during peak summer, you can opt to make early morning applications for greater benefit to your lawn. It would help if you also considered fertilizing your grass when the soil is moist for faster nutrient absorption and lesser harm to your grass.

Preferably, you should fertilize your grass a maximum of four times annually but with an allowance of two times a year for most homeowners. Optimal and controlled fertilizer application ensures that you don’t burn your grass. However, another adverse effect of excessive fertilizer is that it can pollute the groundwater and other water sources in sandy soils.

3. Weeds

Besides the nutritional proportions in liquid fertilizers, you can also choose fertilizers with feed and weed control formula. If the weeds are extensive, you can consider such a product for weed control to optimize your grass’s growth eventually. However, if the weed menace is not large, you can choose to make your grass healthier to choke weeds eventually.

This liquid fertilizer might be expensive but will make your work easy by using the same formula to eliminate weeds. However, if your grass is already healthy and you need only to eliminate weeds, you can use an exclusive weed killer to avoid burning your crops with excess fertilizer.
