Factors To Look For When Buying Best Fertilizer For Garden

1. Plant Requirement

Different plants have different requirements according to their growth pattern. Besides the condition of the soil, type of plant also matters extensively to determine the requirements from the fertilizer. Primarily, nitrogen, potassium, and phosphorus are the three most essential elements required by plants to thrive. The kind of garden you have or the plants in your garden determine your fertilizer need.

Before looking for the best fertilizer for garden, it is important to understand your requirements, that which elements work how. For example, Nitrogen is one of the most essential out of these three, since it is the element which strengthens a plant and helps them to thrive into lush green, healthy plants.

Besides, healthy plants have a natural and inbuilt guard against bugs and pest attacks. Phosphorus too plays a vital role in nourishing and vitalizing the strength and potential of plant roots. Now, once you can recognize the particular requirement of your garden, you can accordingly seek a fertilizer with a particular element in high proportion.

2. NPK Proportion

Availing a fertilizer from online stores, nursery, or any plant care store is easy, but for that, you need to understand the difference between the products in terms of their content. Every fertilizer contains three main elements, namely Nitrogen, Potassium, and Phosphorus. However, every fertilizer varies in their proportion, and this is what differentiates the utility of any fertilizer.

To make it understandable, every fertilizer brand mentions this proportion in three digits, like 5-10-10 or 30-10-20. These numbers are nothing but the percentage of each element in the composition of the fertilizer.

Since each element has a different role to play in the growth and healthy maintenance of a plant, the difference in their percentage matter significantly.

For example, if you need your plant to have more flowers and fruits, you need to offer nitrogen content, whereas to prepare your garden for the upcoming winter with dry weather, you need to offer more Potassium. Likewise, according to your requirement, it is important to focus on the proportion of the elements you choose in a fertilizer.

3. Minerals

To grow healthily and produce fruits and flowers or vegetables, plants need more than the above mentioned three nutrient elements in the soil. Plants need an array of minerals along with these basic elements, like iron, sulfur, calcium, copper, magnesium along with even smaller amounts of molybdenum, zinc, manganese, and boron. These minerals can be found in a good amount in organic fertilizers. Soil that is enriched with nutrient value allows a plant to grow healthily and offer the best gardening or agricultural output.

4. Release Strength

The release strength of any fertilizer is also important while you are considering the best fertilizer for garden. Mostly, when you use a water-soluble fertilizer, they happen to offer rapid results, since these fertilizers offer chemicals and nutrients in their pure form directly to the soil. But if you do not consider the proportion of elements in strong fertilizers, it can lead to fertilizer burn.

This is a term used when too much of any element causes harm rather than good to a plant. Like too much nitrogen offered at a time or through a fertilizer with a fast release system can lead the nitrogen to suck all water content from the plant and make it dry like burnt.

This is why many people prefer slow-release ones as best garden fertilizer over fast-release fertilizers, since they release nutrients and elements at a slow and steady rate, allowing the plants to adjust with the sources and use the essential elements as required.

They are made to release their nutrients at a rate at which plants can use them. Although these slow-release fertilizers might not showcase outstanding results rapidly, they are risk-free from harming your plants with fertilizer burn.

Compared to water-soluble fast-release fertilizers, slow-release fertilizers tend to cost more. However, since you do not need reapplication every week, the cost differences line out.

5. Organic Preparation

Chemicals always tend to have their range of side effects. However, when you want to eliminate the course of side effects that might crop up on using chemical fertilizers, switching to organic fertilizer is the best fertilizer for vegetable garden.

They are crafted out of the by-products of the food industry with wastes like corn gluten meal, chicken manure, alfalfa meals, chicken feathers, along with animal wastes to organic scraps. However, these by-products need processing to form fertilizer.

These need to be broken down by microorganisms of soil so that their nutrients can be easily absorbed by plant roots. Grass clippings to leaves, trimmed wastes of the garden to kitchen scraps, all can be effectively used to make organic compost. Moreover, these organic wastes are the processing materials of organic fertilizer which can offer healthy growth and high nutritional value to your garden soil.

FAQs on Fertilizers For Garden

Q1. What Do Plants Need From Fertilizers?

Earth’s soil contains more than 3800 minerals approximately and almost 118 elements. However, speaking of plants, they only need hardly 20 elements altogether to grow and flourish. To survive and thrive, plants have an inbuilt mechanism that extracts carbon, hydrogen, and oxygen on exposure to air and extracts the remaining elements directly from the soil.

Now, among these 17 elements, some elements are required in higher proportion to grow healthily. This group contains Nitrogen, Potassium, and Phosphorus. Now the remaining elements are different minerals like zinc, magnesium, iron, copper, sulfur, etc. which are also known as micronutrients. Fertilizers are chemically, synthetically, or organically prepared to deliver these essential elements and enhance the soil nourishment and help plants to grow healthily.

Q2. How Often Should I Fertilize My Plants And In What Quantity?

The application frequency of fertilizer and the amount required for any plantation or garden is dependent on a few factors like fertilizer type (granular or water-soluble), plant species, soil type, season, etc. To determine the type of fertilizer your garden or veggies require, the foremost essential thing to do is to conduct a soil test.

  • In the case of home gardening, since plants are in pots, routine fertilization helps in summer, fall, and spring

However, these are basic outline ideas of fertilizing plants, as different types of plants differ in their fertilizing requirements, elements which they need to grow, and rate of application of the fertilizer.

Q3. Is A High Proportion Of NPK Is Best?

It is not the high proportion of elements in best vegetable garden fertilizer that helps your garden to flourish, but the required amount in the right blend that triggers plant growth. For example, organic fertilizers have high nitrogen, but this form of nitrogen is found in an insoluble form. It takes time to break down in the soil and release nitrogen. However, it offers an effective amount of nitrogen release compared to synthetic fertilizers.

If you are using a fertilizer with lower content of NPK, you might need reapplication at regular intervals. However, excessive amounts of elements can lead to adverse effects as well as fertilizer burn. On the same note, organic fertilizers have minimal risks of fertilizer burning the plants, and effectively release NPK along with micronutrients. This encourages microbial life thriving in the soil, thus enhancing the nutrient value of the soil.

Thus, the NPK proportion required for every garden differs as per the plant type and soil requirements.

Q4. How Long Does Granular Fertilizer Take To Dissolve In Soil?

Granular fertilizers, as compared to water-soluble fertilizers, take longer time to act, dissolve, and finally release the elements in the soil. Generally, the routine gapping between the application of granular fertilizers tends to be 6 to 8 weeks. This type of fertilizer is categorized under slow-release fertilizer, which acts slowly yet effectively. This means it requires only one application in the growing season.

To offer optimal conditions so that your fertilizer dissolves fast in the soil and effectively, it is important to offer water after fertilizing. After fertilizing, within 24 hours, the soil needs to be watered sufficiently to allow granular fertilizers to dissolve.

Q5. What Is The Best Fertilizer For A Flower Garden?

Different types of plants have different requirements to grow. Flowering plants need all the basic elements, namely nitrogen, phosphorus and potassium in accountable amounts to grow abundant fruits or flowers. To ensure that your flower garden is decorated with blooming flowers and buds, you need to offer the plants an essential amount of phosphorus.
