Best garden fertilizers for summer 2021

Fertilizers

Water soluble fertilizers have the advantage of delivering nutrients to plants fast while granular fertilizers have the advantage of delivering nutrients to plants longer.

Garden fertilizers

Planting a garden is a great way to make use of any available space you have. Yet, the image of the perfect garden in your head might not become a reality due to the quality of your soil.

Plants take in nutrients from even the best potting soils, and this may eventually lead to the soil lacking the vital compounds and elements necessary for healthy plant growth. A solution to this problem is getting garden fertilizer because it adds the nutrients that flowers, vegetables and other plants grown at home need to flourish. 

The range of garden fertilizers in the market is wide and choosing the best one can be a daunting task. These top fertilizers will give you great results. 

Things to consider when choosing a garden fertilizer

The deficiency in your soil 

The purpose of applying fertilizer to your garden is to add the nutrients your plants need that the soil is lacking. The best way to know this is to test your soil before buying the fertilizer. 

The nutrient concentration and release

You can get a fertilizer with the nutrient concentration your soil and plants need, but its release rate can mean the difference between nutrient balance and root burn. 

The weather outside on application day

If you apply the fertilizer during the rainy season, the chances of it washing away are high. If you choose a windy day to apply dry fertilizer, the wind may carry it away.

The micronutrients present

For soil to be healthy enough for plants to thrive, it needs some common micronutrients. These include zinc, iron, manganese, copper, magnesium, calcium, boron and sulfur. Micronutrient deficient soils often have pest problems and offer slow rates of germination.  

The amount of filler in the bag

The four major components of the average fertilizer are nitrogen, potash, urea and filler. The first three components are nutritious, but filler hardly ever adds any value. If the fertilizer has a high percentage of filler, its quality is likely low. 

Consider the pellet size 

If the different components that make up the fertilizer are of varying sizes, some nutrients will isolate themselves. This makes the application process difficult. Fertilizers made of same-sized pellets blend properly and are more effective.

Prices of garden fertilizers

Garden fertilizers range in price depending on the manufacturers and the type of fertilizer you need. The cost of phosphate, urea and potash will have a direct effect on the final price of fertilizer since these are the main components of the average fertilizer. Prices may range from $10-$80, which can translate to spending between $0.10-$0.50 per square foot of garden or lawn.
