So whether you’re just getting started with gardening or you’ve been doing it for years, read on to learn more about the best fertilizers for your needs!

What Is Fertilizer?

Fertilizer is any material, either made from synthetic or organic substances, that you add to the soil or plant tissue so that it can provide nutrients for the plants. The best fertilizers will help feed your lawn and garden with essential minerals in order to grow healthy plants. There are many different types of fertilizer, and they are used in a wide variety of situations.

In the past, fertilizer was made up of primarily organic substances, such as both animal and human manure, compost, harvested minerals, and crop rotations. In the last few centuries, synthetic fertilizers have become prevalent as well, and particularly fertilizers composed mainly of nitrogen, phosphorus, and potassium.

How Does It Work?

Fertilizers encourage the growth of plants. They do this in two ways. The first is to provide nutrients that the plants need and can use to grow. Fertilizers provide mainly nitrogen, which encourages leaf growth, phosphorus, which develops the roots, flowers, seeds, and fruit, and potassium, which promotes stem growth, the movement of water within the plants, and flowering and fruiting.

There are three secondary macronutrients – calcium, magnesium, and sulfur, as well as many micronutrients such as copper, iron, manganese, zinc, and boron.

The second function that some fertilizers may have is to improve the soil’s ability to retain moisture and support aeration. However, this is not very common and is negligible in relation to the nutrient addition fertilizers provide.

Types of Garden Fertilizers

There are multiple types of garden fertilizers. The three main kinds are granule fertilizers, liquid fertilizers, and fertilizer spikes.

Many of the best fertilizers for your home landscape will come in one or more of these three forms. It is important to know that each option has its own benefits and weaknesses, so choosing the right type can help you improve your garden’s health

If you’re looking at granules, liquids or spikes as a possible option for fertilizing your yard this year, it may be helpful to know what each type does differently. Each type of fertilizer can come as organic or inorganic.

Granule Fertilizers

Gardeners either incorporate fertilizer granules into the soil at planting or “top dress” them on. Simply put, top dressing means sprinkling the granules over the plant’s root zone. You can get either slow-release or quick-release granule fertilizers. Slow-release granular fertilizers, also known as “monthly feedings,” release nutrients gradually over time. Quick-release granular fertilizers, often known as “weekly applications,” deliver nutrients more quickly but in smaller doses.

Granular fertilizers must be mixed into the dirt manually but can last much longer than liquid types which need reapplication every few weeks. You can use a fertilizer spreader to distribute the fertilizer safely and evenly over your lawn.

Liquid Fertilizers

Liquid fertilizers include dry granules and liquid concentrates that must be mixed. They are made up of either inorganic or organic compounds. Spraying the roots of seedlings, vegetable plants, and other types of plants is an effective way to feed them. Over-watering seeds can cause them to wilt and die; in many cases, applying liquid fertilizer directly to plant leaves may be more successful than soaking the roots. This type of fertilizer starts to effect the plant immediately.

Liquid fertilizers are often diluted with water before being applied to soil so they don’t create potentially harmful runoff when not used properly.

Fertilizer Spikes

Fertilizer Spikes act like slow-release fertilizers, releasing a constant flow of nutrients over time. The spikes, which have a low-profile design, are the most efficient way to deliver fertilizer to the roots of your plants. The nutrients are released, and the plants are automatically fertilized, when they’re watered with rain or with a hose. Simply plant them next to a living plant, once per year, and that’s all there is to it.

Fertilizer spikes provide immediate nutrient release by running along roots where they’re needed and can be used on most landscape types. These fertilizers are also made with either organic or inorganic materials. Calculate the amount of spikes required for a plant based on its size and the manufacturer’s recommendations. Place the spikes evenly around the plant’s root zone and push them into the soil.

Organic vs. Inorganic Fertilizers

Regardless what type of fertilizer you use, it will either be inorganic or organic. These two subsets of fertilizer differ on two levels – they use different ingredients and the nutrients get introduced to the plants in different ways.

Synthetic or commercial fertilizers are the most common type of inorganic fertilizer. These fertilizers are often known as manufactured fertilizers because they are produced through chemical synthesis; nevertheless, the majority of them include nutrients from naturally occurring mineral deposits. These fertilizers are highly concentrated and directed at exactly what the plants needs and nothing more.

Inorganic or artificial fertilizers are produced from the chemical compounds of nitrogen, phosphorus, and potassium that have been synthesized in industrial processes. These then contain primarily one or more of these ingredients in high concentrations, and focus on providing nitrogen, phosphorus, and potassium to the plants.

Compost, manures, blood meal, alfalfa, cottonseed, and kelp meal, and bone meal are all examples of organic fertilizers, which come mainly from plant and animal sources. The NPK levels in these fertilizers are usually lower than inorganic ones, but vital organic matter is added to the soil, which enhances moisture movement and works in tandem with living microorganisms in the soil to nourish plants.

Another interesting consideration when comparing different types of fertilizers is how they react in wet conditions. Organic products typically break down more quickly than their synthetic counterparts do, so if you have an area where water may pool after rainstorms, you may want to stick with synthetic, quick-acting products.

Key Shopping Considerations

Here are a few factors to consider when shopping for fertilizers.

N-P-K Ratios

One of the most important factors when choosing fertilizer is nitrogen-phosphorus-potassium (N-P-K) ratios because these are necessary for plant growth. Your goal should be to find a ratio that matches what your plant needs based on its species type’s requirements.

Before applying fertilizer, it’s usually ideal to conduct a soil test to determine your garden soil’s natural fertility. Contact your local Cooperative Extension Service to obtain a soil sample for testing. The findings will show which elements your soil may require, so you can add them in the form of fertilizer.

Fertilizer products tend to list the NPK ingredients on the bag in a ratio format, like 10-10-10 or 4-3-4. The number list is always in the sequence N-P-K.

Nitrogen is the main necessary compound for leaf growth. Phosphorus develops the roots, flowers, seeds, and fruit. And potassium promotes stem growth, the movement of water within the plants, and flowering and fruiting.

Slow Release vs. Quick Release

Slow-release fertilizer should keep plants nourished for an entire growing season, as long as it is properly applied. This fertilizer can be either organic or inorganic, though it is more commonly organic. Organic slow-release fertilizer is broken down by soil microbiota and made available to plants. Manufacturers design slow-release inorganic fertilizer pellets to dissolve gradually as water passes through the soil. Because these fertilizers take time to act and are slow-releasing, they should be used in the fall and worked into soil once more.

Inorganic fertilizers can also be quick-release. This kind of fertilizer permeates completely into the soil in just a few weeks, providing your plants with a fast supply of nutrients. Quick release fertilizers should be applied multiple times, up to every two weeks, throughout the growing seasons.

Plant’s Needs

Different sorts of plants, as well as those at various phases of development, require different nutritional levels. Are you starting a new flower, vegetable, or herb garden? Perhaps you can use a starter fertilizer to help the young plants get established in their new location.

Do your azaleas, gardenias, camellias, or blueberries seem to be withering away? Give them a boost with a fertilizer specifically made for acid-loving plants. Plants that bloom and fruit require higher phosphorus plant food, and plants grown for foliage require more nitrogen.

These are all thoughts you should be having before purchasing a fertilizer for your backyard plant life.


Fertilizers help plants grow healthy and produce fruit. But the question always is how much should you purchase? The frequency with which you fertilize your plants is determined on the type of soil you have and whether they’re in containers or raised beds. Most plants that thrive in porous, well-drained soil or in pots require more frequent feeding, usually every three weeks to a month during the growing season. Clay soil is often less demanding on plants when it comes to fertilizer. After planting, one dose every four to six weeks should be sufficient.

Granular fertilizer will often go further than liquid fertilizer. Examine how much area one bag or bottle covers against the square footage of your garden beds to determine how much fertilizer you’ll require. This will tell you how much fertilizer your plants will require throughout the year.
