Best Garden Fertilizers

Fertilizers are organic or synthetic substances used to provide plant nutrients which are inadequate in the soil, to enhance growth and fertility. Fertilizers may also be used to boost water retention as well as filter excessive water to enhance soil effectiveness. Generally, fertilizers provide three major macronutrients to plants; phosphorus, potassium, and nitrogen. Other fertilizers may also include secondary nutrients like magnesium, calcium, and sulfur to the soil.

Fertilizers are common commodities used by farmers, gardeners, or families to facilitate the growth of crops or gardens grows.

The manufacturers of fertilizers have developed a wide range of fertilizers to suit all farming scales, from the small garden of plants or flowers to a large plantation with thousands of crops.

How fertilizer is used

Before I cover how to effectively apply fertilizer to your garden, perhaps I should demystify some of the common myths about the fertilizer and plants.

Here are common misconceptions not many people know about fertilizers:

  • Fertilizer is not a plant’s food. There are numerous publications and online forums that define fertilizer as simply plant food, which is wrong. Plants produce their food by the process of photosynthesis. What fertilizers do is provide elements that are deficient in the soil, such as potassium and nitrogen.
  • More is never better. Don’t apply too much fertilizer hoping that it will lead to high yields. Plants will absorb the exact amount of nutrients needed and the rest will go to waste or abnormal growth.
  • Not all plants need fertilizer. Remember, the fertilizer is meant to supply the elements that lack in the soil, but if the soil of your garden has these elements, then there is no point of applying fertilizers.
  • Slow is better. Fertilizer that releases granular slowly allows the nutrients to be absorbed in a controlled and safe manner.

There are two major categories of fertilizers, liquid and granular fertilizers.

How to apply granular fertilizer

Granular fertilizers can be applied by simply broadcasting them with a spreader or your hands (some fertilizers have burning sensations) onto the surface of your garden or lawn. Consider adding some to the planting holes or rows before sowing your seeds. Spread the fertilizers evenly on the surface of the garden to about 4 to 6 inches. Use your watering can sprinkle water after applying the fertilizer to speed leaching down the soil and the roots of the plants.

In a growing garden, apply a small amount to supplement the nutrients already in the soil. Add thin layers of fertilizers in rows of crops or the drip lines of shrubs or trees. You fertilizer package should have directions on the label, so make sure you go through it.

How to apply liquid fertilizer

Liquid fertilizers are absorbed quickly and easily by plants. Depending on the directions on the label of the fertilizer, apply the fertilizer on the surface of the soil, and not on top of plants. Liquid fertilizers may require you to dilute with water before applying.

Most liquid fertilizers are applied biweekly and contain a high amount of nitrogen which enhances rapid foliage growth.

There are also other types of organic foliar sprays that are applied to the plant vegetative areas to promote prolific blossoming.

When applying liquid fertilizer, you should be careful not to contaminate your fertilizer with herbicides. It is a common mistake among gardeners who don’t have enough equipment. 

When to apply fertilizer to your garden

Crops benefit significantly with the early-start fertilizing schedule. Some plants need just light application while others require more and regular applications.

Use the directions on the product package and follow the instructions on the interval of applications.

For granular fertilizer, it is highly recommended to apply before the rain so that it can dissolve into the soil faster. On the other hand, liquid fertilizers are best if applied during dry months either early in the morning or early evening.
