Buying Guide To Choose The Best Fertilizer

There are some specific attributes you need to look for in the best fertilizer for fruit trees. The fertilizer has different types and different compositions.

Here are some essential things you need to look for in your fertilizer:

Nutrients:

The soil has nutrients, but they are not enough for the better growth of the plants. The main micronutrients the plant requires are phosphorus, potassium, and nitrogen (NPK). You see three numbers on the bag of fertilizers. These numbers represent the ratio of these micronutrients.

All these nutrients have a significant role in the growth and development of a plant.

  • Nitrogen:

A large amount of nitrogen is required by the plant for good growth.

  • Phosphorus:

An essential quantity of phosphorus is needed for root development, and it also encourages flowering and blooming.

  • Potassium:

Potassium's significant amount is also needed for the production of fruit. An adequate amount of potassium is vital for the production of excellent quality fruit.

Like micronutrients, macronutrients are also a necessary thing for the better growth of plants. The macronutrients that plants need are sulfur, magnesium, and calcium. Some other micronutrients that are boron, iron, zinc, and manganese, are also required by the plant but in miniature. The fertilizer adds to the quantity of these nutrients that are already present in the soil. Fertilizers fill up the deficiencies of these nutrients. Calcium is essential for citrus fruit, so when looking for a good fertilizer for citrus, look for extra fertilizer composition.

Synthetic Fertilizer or Organic fertilizer:

Synthetic fertilizer and organic fertilizers both have their uses and drawbacks. You can use them according to your needs and preferences.

Synthetic fertilizers:

The NPK ratio is always higher in synthetic fertilizers. It provides a large number of nutrients to the plant resulting in remarkable growth. But the drawback is that those synthetic fertilizers leach out of the soil more quickly, so the plants are needed to be fertilized more often. And they don't ensure the solid and long-lasting health of your plant.

Organic fertilizers:

On the other hand, organic fertilizer has a small ratio of NPK. The organic fertilizer also enhances the soil's biological processes; they increase the number of earthworms and microbes. Organic fertilizers increase drainage, aeration, composition, and texture. It also promotes good root development and nutrient uptake. They reinforce bacteria and fungi present in the soil to facilitate the availability of nutrients for the plant.

If you want quick and instant results in an affordable range, then go for synthetic fertilizers. Still, organic fertilizer gardening is ideal for you if you wish to have microbe-rich soil and enjoy a healthy plant.

Important FAQ's Regarding Fertilizers

1. Is it okay to blend different fertilizers to apply on fruit trees?

It is not preferable to mix fertilizers because plants respond to every fertilizer differently. When sprayed on the leaves or the soil, the plant has different results and provides nutrients specific to leaves and mud. The composition gets mixed up when the fertilizers are blended. This mixing of fertilizers might make some critical nutrients unavailable for the plant or damage the plant. If you want to use a new fertilizer after already fertilizing the plant, then wait until the fertilizer is all used before applying a new one.

2. Does fruit trees require manure?

Yes, fruit trees do need manure because it contains beneficial microbes and nutrients. But the nutrients in the waste are present in less concentration, so they don't meet the need of the plants. It is advisable to use manure with fertilizers because they both will provide more benefits other than nutrients. Like they will improve the condition of the soil, they will both increase the nutrient concentration, insect and draught control-all in all, they make up for all the deficiencies of the plant.

3. The plant requires how much fertilizer?

That depends on certain factors like mostly needed nutrients by the plant, the condition of the soil, the area of the tree, age of the tree. The manufacture usually mentions how much fertilizer is required in these situations. For instance, in the case of nitrogen, one lb. is given to 8+ mature trees, 0.125 lb. to a year-old tree, and so on. These instructions should be followed religiously to have the desired effects.

Conclusion For Fertilizer Buyers

If you want to have a good harvest, you have to choose good fertilizers for your fruit trees that meet their every need. For better results, you should know basic information about the tree you will grow and its requirements. Then it would help if you decided which form of fertilizer would be ideal for your plant. Liquid fertilizers are perfect, but they might turn out to be challenging in terms of blending. Spikes and granules are also simple options that don't need constant application. In the end, it is up to go for the best possible fertilizer for your fruit plant.
