Factors to Consider When Choosing the Best Fertilizer for Fruit Trees

Different fertilizers for fruit trees contain relatively different ingredients. Even those that contain almost similar ingredients may differ in type and concentration. Thus, there’re certain factors you should consider before buying a fertilizer to know whether it’s suitable for your fruit trees. Let’s discuss some of these factors.

1. Type of fertilizer

Fertilizers for fruit trees are available in three types including liquid concentrates, spikes, and powders. Liquid concentrates and powders are typically mixed with water before application. They’re advantageous in that they’re quickly absorbed by plants. However, you must make sure that you mix in the recommended ratio to avoid burning your fruit trees. Also, you need to ensure that the liquid concentrate or powder you’re choosing is water-soluble to avoid clogging the sprayer and to ensure it is applied consistently and evenly.

On the other hand, spikes are premeasured. They don’t require any mixing. Thus, spikes are less laborious and easier to work with than liquid concentrates and powders. Spikes are applied by hammering them into the soil. However, some spikes tend to crumble when hammering them. Preferably, choose spikes that come with a plastic cap that protects them from crumbling when hammering them.

2. Ingredients

It’s important to ensure the fertilizer you want to buycontains all the key ingredients required for the results you want to get. Essentially, it’s recommended to choose a fertilizer that contains all the basic ingredients that boost overall growth and yield. Most fertilizers for fruit trees contain nitrogen, phosphorous, and potassium. These ingredients are usually indicated on the packaging as NPK ratio such as 10-5-20 for example.

The role of nitrogen is giving leaves a greener color to encourage photosynthesis. On the other hand, phosphorous assists fruit trees to develop more flowering points and stronger roots. Potassium controls water pressure within and outside cells. Potassium also boosts metabolism and the development of stronger roots. Thus, a fertilizer with all these three ingredients will enjoy healthier overall growth for enhanced fruit production. Secondary nutrients such as calcium, zinc, iron, manganese, magnesium, and sulfur among others are an added advantage.

3. Frequency of application

Different types of fertilizers have a specific frequency of application. Liquid fertilizers are typically applied more frequently than powders and spikes. Thus, they’re more laborious to work with. On the other hand, spikes are designed to release nutrients slowly but continuously. Thus, spikes are typically applied once a season, making them less laborious to work with. Ensure you follow the guidelines on the fertilizer packaging about the frequency of application.

4. Applicable growing method

Ensure the fertilizer you want to buy is suitable for use in the growing method of your fruit trees. If you’ve planted fruit trees in pots and containers, ensure the fertilizer is ideal for use in containers. Also, if you’re growing fruit trees in special growing methods such as hydroponics and aeroponics, ensure the fertilizer is suitable for the specific growing method.

Final Words

As you can see, there’re numerous types and brands of fertilizers for application on fruit trees. Thus, it’s important to do thorough research about different fertilizers before making your choice. Ensure the fertilizer you choose is suitable for the kind of fruit trees you’re growing. Also, it should be convenient to use depending on your situation.
