You’ve seen some of the best organic lawn fertilizers on the market, but how do you decide which one is right for you? Each fertilizer has its qualities and can appeal to different people. The guide below will help you determine which fertilizer you should choose, as well as providing some details about why you should be using organic fertilizer on your lawn.
Why and when you need to start using organic lawn fertilizer?
So why would you even want to use organic fertilizer and when is the right time to apply it? Here’s all you need to know:
How It Works – Organic fertilizer is rich in organic matter and rich nutrients. It works by boosting the rate of nutrient exchange in your soil, feeding the billions of micro-organisms that live beneath the surface and providing a healthier and more fertile environment for lush, green grass to grow.
Healthy Soil – When the soil is rich and healthy, it retains moisture better and draws in more earthworms too, which help to provide aeration and drainage and feed your plants too.
Long Lasting – Many chemical fertilizers simply get absorbed into the soil and washed away rather quickly. Organic fertilizers tend to last a lot longer as the organic matter takes a while to gradually break down. They release nutrients slowly, feeding your plants over a long-term period. This means you won’t even have to mow the lawn as often.
Totally Safe – Since organic lawn fertilizers are made with nothing but organic matter, they don’t contain any toxins or chemicals. This means they’re fully safe for when your kids or pets are playing on the lawn, and they won’t damage the environment or any wildlife either.
When To Use – The moment you need to think about using organic lawn fertilizer is when you notice dry, brown, or weak grassy areas where the lawn clearly needs a helping hand. You may also want to use fertilizer after very dry spells of weather or after heavy rain that may have washed nutrients away.
How to pick the best organic lawn fertilizer?
There are a lot of different organic lawn fertilizers out there and many different brands to choose from. Each product has its own unique advantages and drawbacks, and finding the right one for your lawn can feel like a challenge at first. To make the process easier, you can break your search down by considering the various key aspects of each product. You need to pay attention to coverage area, type of fertilizer, the nutrients contained within, the weight of the product, and its price. Read on for further details.
One of the first things to think about when shopping for organic lawn fertilizer is how much lawn you actually have and what kind of coverage area you need from the fertilizer. It’s no use buying a bag or bottle of fertilizer and then realizing you don’t have enough for your lawn, so this is a key issue.
Some organic lawn fertilizers boast huge coverage areas per bag. Super Juice All in One Soluble Supplement Lawn Fertilizer, for example, offers coverage of an entire acre (or 43,560 square feet) of lawn per bag. This makes it a great choice for those with large lawns and extensive properties.
The type you choose depends on how much you’re willing to pay and how quickly you want the fertilizer to take effect. A liquid fertilizer will be absorbed into the soil more easily and rapidly, taking effect sooner than a dry mix. Liquid fertilizers are also a little easier to apply, as dry mixes need to be scattered around evenly but liquids can simply be poured out onto the lawn.
The whole point of an organic lawn fertilizer is to provide much needed nutrients to the soil. The best organic lawn fertilizer products work to enrich the soil, providing a healthier ecosystem for micro-organisms and certain insects to help your lawn grow faster, stronger, and greener. However, it’s vital to ensure that the fertilizer you use contains the right nutrients.
When shopping for the best organic lawn fertilizer, you also need to consider the weight of the bags or bottles you’re buying. A lighter bag will be easier to carry around and store, as well as being easier to empty out.
The cost of organic lawn fertilizers can vary quite greatly. There are some very cheap options out there, like our Budget Pick: Milorganite 0636 Organic Nitrogen Fertilizer. There are also more expensive variants, typically offering larger coverage areas or a wide range of nutrients in the mixture. The best organic lawn fertilizer brands charge higher prices and will usually offer stronger performance, but you don’t always have to buy the most expensive option.
The key with organic lawn fertilizer prices is to find a product that works with your budget and also offers the right amount of coverage and decent nutrients for your lawn. All of the products in our list offer great results, but have varying prices. If you need a whole lot of coverage, you might have to invest in a more expensive alternative, but if you only have a small lawn, one of the cheaper options should suffice.
How and when to use organic lawn fertilizers?
The way in which you use your organic lawn fertilizers will depend on the type you buy. If you buy a liquid lawn fertilizer, you can simply spray it around on the lawn or even make use of a hose sprayer or pump sprayer to apply it evenly. This is one of the advantages of liquid fertilizers; they’re very easy to apply and sometimes you don’t even need to do anything except set up a sprinkler.
If you buy a dry mix lawn fertilizer like Safer Brand Ringer Lawn Restore, meanwhile, you can simply scatter it around across the lawn. The best way to apply these fertilizers is to spread them around evenly. You usually don’t need to dig down into the ground or anything like that, although this can help certain nutrients like phosphorous to break down and be absorbed more easily.
The best time to use organic lawn fertilizers is a few months before planting your seeds. Many people apply fertilizer in the fall or early winter, prior to planting new seeds in the spring. Since organic lawn fertilizers need time to break down and take effect, this is a good moment to use them and let their nutrients have time to be released and seep out into the soil. This is the case for dry fertilizers, but liquid variants don’t need to be applied so early as they act much faster.
The big difference between organic fertilizer and regular chemical fertilizer is that the organic variant doesn’t contain any harmful chemicals or toxins. It’s nothing but pure plant nutrients, meaning it’s totally safe for your family, your kids, and your pets. Since it’s so safe, you don’t need to worry about damaging your lawn by using too much or having to deal with any spillages or clean-ups. It’s also much kinder to the environment and ecosystem of your lawn, massively boosting the health and fertility of the soil. It creates the perfect conditions for your lawn to grow. In short, organic fertilizer is the ultimate option for keeping your lawn healthy and happy.
Quite simply, you’ll know if the fertilizer is working by the fact that grass and plants begin to grow. If life is appearing in the area where you apply the fertilizer, it’s a sure sign that the fertilizer is doing its job effectively. It enriches the soil, provides vital nutrients for countless microorganisms, and helps you lawn stay green and lush. If areas appear brown, barren, dry, and lacking in life, that’s a sign that any fertilizer in the area isn’t very effective. It’s important to remember, however, that dry mix organic fertilizers can take some time to be absorbed into the soil and start having an effect.
It’s not recommended to apply fertilizers directly to lawn seeds. This is true of organic fertilizers too. Even though they’re free of chemicals, they can still pose a risk to a fragile little seed. Applying fertilizer direct to the seed can cause burning and prevent the seed from ever sprouting. Instead, the best thing to do is to apply fertilizer shortly before planting your seeds. This gives the fertilizer time to start breaking down and nourishing the soil, providing the perfect foundation for the seeds to start growing when they’re planted.
The next best organic lawn fertilizer is the Safer Brand Ringer Lawn Restore. Free of any nasty odors and made up of nothing but pure plant materials, this fertilizer can really enhance the look and health of your lawn in a matter of days.
