What’s a Liquid Fertilizer?

Before you go ahead and purchase fertilizer for your lawn it’s good to know what you’ll get.  Liquid fertilizer is a highly concentrated solution that can provide instant food for your plants through the soil and foliage.

It offers immediate results that are visible in a few weeks. This is a fast-release fertilizer which means that multiple applications might be required depending on the product you use and the needs of your lawn.

Also, it’s essential to test your soil to understand what type of fertilizer it needs and what the ideal NPK would be.

Our advice is to take your time and do your research before adding a product to the shopping cart. Slow and well-thought decisions can bring you fast and quality results.

What are the Benefits of Liquid Fertilizers?

Highly Concentrated Liquids

Even a small bottle of liquid fertilizer can be used multiple times due to the high concentration of the liquid.

In the long run, this can save you money and when compared to a granular fertilizer it’s easier to use and carry around your yard.

Also, depending on your gardening needs you can dilute the concentrate as you wish and most of the products we presented can be used all year round regardless of the weather conditions.

Easy Application

As we mentioned previously, using a liquid fertilizer is quite easy and makes your gardening activities enjoyable. Most of the bottles can be directly connected to a hose and just sprayed on the needed surface.

Because of the spraying application, you can be certain to have an even coverage that others can’t provide – all areas of your lawn will be fertilized evenly.

Fast Results

Unlike granular fertilizers, the liquid option can get deeper in the soil and reach the roots of the plants much faster which gives faster results.

How often to Apply Liquid Fertilizers?

This depends on the product you use. Some of them have specific instructions on how often to be used.

According to professionals, you can use a liquid fertilizer up to 4 times a year. Have in mind that anything over 4 times can damage your lawn and you can even lower this to 2 times a year and still get great results.

As we mentioned in our reviews, when it comes to fertilizing, more is not always better so you should be cautious about how often you use fertilizer.

When to Add Fertilizer?

Experienced gardeners explain that to get the best results you have to work with a fertilizer schedule to help you understand when’s the best time to fertilize.

Don’t just go with the flow and apply fertilizer whenever you find something on sale.

  • If you decide on fertilizing once a year then our advice would be to do it at the beginning of September when the lawn needs food the most. The grass can recover after the growing season and absorb the nutrients easily and prepare for the harsh winter.
  • If you want to do it twice a year then add another spraying in the middle of October to give the lawn another boost before wintertime.
  • Adding a third fertilizing should be in the middle of spring.
  • And the fourth and final should be in the middle of summer and you should do it only if you deem necessary. If you decide to apply in summer, make sure the weather is not too humid and hot since the combination can harm the grass.

What’s the Needed Equipment?

The products we reviewed in our article all come in practical bottles that can be directly connected to a hose for an easy application.

However, any additional equipment you might need depends on the size of your lawn and before deciding on a liquid fertilizer you should take this into consideration.

You might end up needing more than just a spraying bottle and hose so be prepared.

Why Use Organic Fertilizers?

Natural or organic fertilizers have recently become more popular because they’re eco-friendly and don’t contain any dangerous ingredients that can cause harm to you, your kids and pets.

Most of the organic fertilizers are made of bone meal, blood meal, feather meal and fish meal and they usually have lower NPK levels i.e. below 10.

Our advice is to apply them in warm weather during growing months depending on the area you live in.

Organic fertilizers can help stimulate microbial soil activity that results in healthy soil and greener grass.

You might find them to be more expensive than other available options however, considering the results they provide they’re well worth the investment.

Tips & tricks for Efficient Use?

There are some ground rules you have to follow when it comes to applying fertilizer – including a liquid one. Below, you can review some of our tips and tricks on how to get the best out of your liquid fertilizer:

  • Always test your soil and choose the fertilizer based on the results
  • Don’t forget to measure your lawn size
  • Follow a smart application schedule
  • Use organic liquid fertilizers
  • Don’t guess the amount of fertilizer – measure how much you need
  • Never apply more than 4 times a year
  • Don’t use phosphorus if your soil isn’t phosphorus-deficient
