What To Look Before Buying Fruit fertilizer

Selecting fertilizer for your citrus is not an easy task as one may think. This could be really confusing for many growers. It is still essential to fertilize each fruit tree accordingly. Even two trees of one fruit may have different nutritional needs. Each fruit type may require different nutrition according to its size, health, and soil. How to know what your plant needs? Important query, but simple to answer. By doing proper research, you can choose the best:

Do Proper Research

Does your citrus need nitrogen, potassium, magnesium, or sulfur? How would you judge this? The only way is to do proper research. know the variety you are going to harvest and type of soil in your area. What should be the main focus of your research?

Here are the simple bullet points:

  • Test the Soil Ph
  • Type of citrus variety
  • Humidity in atmosphere
  • NPK wrote on the fertilizer bag
  • Basic Nutritional requirement of Citrus
  • Fruit-bearing time and season
  • Seasonal changes

By keeping all these deciding factors in your mind, your research for top quality fertilizer will succeed. Otherwise, you may choose the wrong product!

Select What is best

Select wisely the product that is a good fit for more than one citrus variety. Maybe there would be diverse lime trees in your garden. So, think about the all-in-one option as it will be cost-effective. Though it’s good to understand each tree’s nutritional requirement according to its growth.

What’s best in compost is an organic one. It’s free from harmful chemicals and odor. For natural formula, you need not fear about pets and kids. Though organic compost affects your plant slowly but at least naturally.

The tree will get what you feed it. It’s up to you to know well about the nutritional requirement of your tree. With research, knowledge, and experience, you can make any compost a regular part of your citrus life. Only knowledge is not enough, try experimenting with different products by separating certain trees to find out which fertilizer works best on what variety.

What Kind of Fertilizers is Preferable for Citrus

How to tell whether any compost is the best fit for your citrus or not? For this, you should know what is the perfect combination of different ingredients each fertilizer must-have. Let me tell you here that citrus needs high nitrogen content. Besides nitrogen, this tree also needs potassium and phosphorus. NPK defines the quality of your fertilizer that is written on the label on the box. 

Check how NPK and other ingredients help your citrus to grow well

Why Citrus need Nitrogen(N)

Won’t you love vibrant green leaves of foliage swaying in the breeze? Indeed, everyone would love to get a healthy harvest. But it’s possible only if you include nitrogen as an essential element for a plant diet. Because of this nitrogen presence,photosynthesis is possible. Without it, there will be no leaf formation or growth in your plants. When leaves will not grow healthy, it will not bear flowers and fruits.

Nitrogen is a basic component of almost all fertilizers especially organic ones. Make sure that your selected one should be higher in nitrogen than other elements. However, it does not mean that only nitrogen contributes 100 percent of the diet. Though its percentage is high yet plant requires other ingredients for nutrition as well 

Why Citrus need Potassium(K)

So far, we know well that nitrogen is necessary to bring lush green leaves foliage. Similarly, Potassium is essential to make your fruit bigger, tastier, and colorful. It also helps plants in quick recovery from unexpected weather conditions like drought, rainfall, fog, and cold.

Water and sugar uptake from roots is only possible due to potassium. It enhances root growth and efficiency to distribute nutrients above in the plant. When mixed with nitrogen and sulfur, it also helps to keep the plant upright as well as sturdy in position.

Why Citrus need Phosphorus(P)

What’s great about phosphorus is that it enhances chlorophyll to capture light for photosynthesis. It not only captures sunlight but also transfers it into energy to boost plant growth. So, without this component, plants would not be able to make food for themselves. Also, it helps in fruit formation, seed growth, and flower formation.

It provides natural immunity to citrus to fight against diseases. Yellowing of leaves and drying leaves are few common plant diseases due to its deficiency. However, it always needs to work in combination with nitrogen and potassium.

Other Essential Nutrients that Fertilizer Must have

Besides NPK, plants also need traces of other elements like microbes, zinc, iron, magnesium, and calcium.Citrus fruit also need traces of these elements. So, make sure before choosing fertilizer it should provide the best mixture of all these nutrients ingredients. It’s good to go for compost that works both as a dietary supplement and fertilizer for your plant.

How and When to Fertilize your Citrus Trees

We are fully aware of this fact that each tree has its specific nutritional requirements. Keeping this fact in mind, you can prepare a fertilizing plan for your garden. All of the products have labels and guidelines. So, do follow them to get expected results. Here are few guidelines depending on fertilizer type that will help you to avoid overfeeding

Granules Fertilizer, Application Time and Season

The most popular form of fertilizer comes in granular shape or powder form. For many years, growers have been using this type as it is easy to spread in big areas. You just need to spread the prescribed amount with hands randomly on the ground.

In the case of citrus, start one application in the fall to prepare your plant for spring. You can use it according to instructions on the menu. Overfeeding is dangerous. Make sure to pour these granules along the drip line. To avoid wastage, mark the line on the ground and then start the process

It is compulsory to water the plant right after its application. Depending on the rain factor, you can increase or decrease watering. Remember dry compost will not be effective as it may not reach roots of plants.

Spike Fertilizer, Insertion Time and Season

One of the most favorite compost comes in the form of a spike. It’s really simple to use. What you need to do is to insert them along the drip line under the soil. Remember to keep a distance of 3 feet between two spikes. Water it well after it’s done.

That’s all simple!

One more thing that is very convenient about spikes is that you need not apply it again and again. They are sufficient to release energy throughout the year, You can apply it after fall or during fruit season once or twice. Safest to use and odor-free, nature-friendly product.

Isn’t it?

Liquid Fertilizers, Application Time and Season

Mostly, soluble in water but not good for direct application. A large number of brands are producing these fertilizers with their own measurement and guidelines. But all of them are used with water. First, pour the required amount of liquid in water and then apply it along the drip line.

The recommended amount is one or two ounces per gallon for citrus. Pour this water along the drip line and then see the results. Dripline determines the position of the root. So, it’s always recommended to mark it before applying any fertilizer type.

Depending on the fruit season, soil quality, and labeled instruction, you can increase or decrease this fertilizer application. You can even use it with daily watering. However, it’s good to apply it after every 7 to 8 days. One more thing, all liquid fertilizers are not meant to spray. So, read instructions fully and then use them in a spray bottle.

Sprays, Time & Season

Sprays work more like a dietary supplement to help the plant recover from diseases. For citrus, if you are facing leaf- yellowing, you can apply the spray directly as prescribed on the label. Remember sprays are not substitutes for fertilizers. They are only meant for lowering the effect of certain deficiencies. The best time for the spray is to apply it in the fruit season after the fall.

Bttom Line

Bye for now now, you know well how to choose the best fertilizer for your citrus trees. Though it’s a bit tricky. However, with proper research and knowledge, you can select one that fits the right needs of your desired plant.

We’ve talked much about spikes, granules, liquid, and sprays. It’s up to you and your plant type what you prefer most. Choosing the wrong one may result in a lot of hassle. So, read well the instructions above the label before buying any product.

Remember only watering is not enough to bear a healthy harvest. So, go on and choose one that’s a good fit for your citrus tree. 

Enjoy yummy citrus this year! Bye for now, but soon we’ll get in touch with more exciting product reviews.
