What Nutrients Work Best For Citrus Trees?

There are two kinds of nutrients which every good fertilizer for citrus trees should have – micronutrients and macronutrients. The plants need the macronutrients in a much larger quantity compared to the micronutrients. These include the following:

 

  1. Nitrogen: It is the most vital nutrient used by the citrus plant. The plant uses nitrogen for the production of flowers and leaves, and of course, the fruits.
  2. Phosphorous: The citrus plants need phosphorous to digest the nutrients and store energy. It is a vital nutrient used for cell division.
  3. Potassium: The citrus trees use potassium for the production of leaves, flowers, fruits. It works in the same way as nitrogen.
  4. Calcium: Calcium, too, performs a similar function as potassium and nitrogen.

Features To Consider While Buying The Best Fertilizer For Citrus Trees

When shopping for organic fertilizer for citrus trees, you need to consider a bunch of factors. It goes without saying, every professional or hobbyist gardener wants the best plant food for citrus trees while still ensuring that the chosen nutrient is easy to use, reasonable, and pretty manageable.

 

To help you find the best citrus tree fertilizer, here we have come up with a few factors that you need to bear in mind when deciding on the best citrus food. Let us get started and address these factors to shop for the best manure for citrus trees one by one.

 

Price

The price range for organic fertilizer for citrus trees is not very wide. Typically, the price for the good fertilizer for citrus trees is usually between 10-40 USD. However, if you opt for the value packs, the cost can rise to 50 USD or above. In our view, the value packs are better as they get you more at once at a lower value than you would possibly get when you buy the spikes or the sprays one at a time.

 

NPK

NPK refers to the three essential citrus tree fertilizers that plants need to grow strong and healthy.

 

In this, N implies nitrogen. Nitrogen is believed to be the best food for citrus trees and is needed for the plants to carry out their photosynthesis process. It is a quintessential piece in amino acids, which can aid in protein construction. Nitrogen also enables the plants to store and utilize the energy. Nitrogen can be found in a blood meal, manure, compost, and feather meal.

 

P stands for Phosphorous, which is another component of good fertilizers for citrus trees. The plants need phosphorous to aid proper root growth and to have the plants blooming. When the plants get the right phosphorous dosage, they build strong structural stability. This enables seed production in the plants. The organic fertilizer for citrus trees to acquire phosphorous include blood meal, compost, and manure, just like nitrogen. Phosphorous can also be availed from bone meal.

 

Lastly, the K in NPK signifies potassium. Potassium is a citrus tree fertilizer, which decides the shape, size, taste, and color of the fruit. When the plants get this citrus tree fertilizer in good quantity, the fruits are naturally better. Potassium, an important component of every good citrus fertilizer can be found in compost and manure too. Alternatively, wood ash is also an excellent source for this best citrus food.

 

Fertilizer type

You have more than one way to provide the plants with citrus tree fertilizers. You can opt for liquid fertilizer for citrus trees or go for a granulated one. The idea is to understand which way best suits you and your plant. Some people spray the best citrus fertilizer over the plants. Upon spraying the good citrus fertilizer, the nutrients directly land upon the leaves. It is also helpful in proper plant maintenance.

 

Further, another way to provide the citrus tree fertilizer to your trees is via a spike. A spike has the nutritional formula in it. So, all you have to do is take the spike and insert it in the soil in your plant’s pot. If you are growing the tree, to provide organic fertilizer for citrus trees, you can insert the spike directly into the ground where your tree is planted. This will, over time, provide your plants the best feed for citrus trees. However, the spike will not last forever. Thus, you need to keep a continuous check on it to see how much citrus tree fertilizer remains in the spike.

 

At times, the best manure for citrus trees goes right over your soil or lawn. This is primarily the organic fertilizer for citrus trees. However, you also come across the chemical formulas, which can be absorbed easily by the roots and the citrus tree’s soil.

 

The powdered citrus tree fertilizer that we recommend includes the Espoma CT4 and Dr. Earth Natural Wonder. However, if you like to use the granules instead, you can opt for the Nelson Citrus Fruit and Avocado Tree Plant Food fertilizers and the J R Peters Inc Jacks Classic Citrus FeEd.

 

Pack volume

Once you invest in a plant, citrus tree fertilizer is also going to be an ongoing expense. To make this investment in citrus tree fertilizer a lot more budget-friendly, you should look for a value deal or pack on multiple packs of organic fertilizer for citrus trees. The good citrus fertilizer will cost you less over time if you make a bulk purchase.

 

You can even avail of a weekly, monthly or even yearly service of consistent good citrus fertilizer, so you never run out and never have the trouble of finding a new brand.

 

Tree care

Some good fertilizer for citrus trees promises to offer you the right nutrients for your plants and guard the plants against potential diseases and insects. In case of an infestation, you can get a pesticide separately. Some good fertilizers for citrus trees have pesticides inside them that are full of chemicals. This implies that you will have to use these citrus tree fertilizers in lesser quantities, so you do not harm your plant.

 

How effective would it be?

Though the general idea is to shop for the citrus tree fertilizer from a top and recognized brand, you should look for organic fertilizer for citrus trees. The organic citrus tree fertilizer works the best since they have minimum chemicals, which the plants can absorb. The best fertilizers for citrus trees are organic fertilizers, but the chemical liquid fertilizer for citrus trees can guard the plants against other factors, such as insects, pollution, and sunlight.

 

Overall, to achieve the best and most effective performance, you need to look for the best feed for citrus trees that is organic and exclusively meant for the citrus plants you are planting.

 

How To Fertilize Citrus Trees With The Best Citrus Food?

When you have good fertilizer for citrus trees at hand, the next big question is how to provide your plants with the citrus tree fertilizer. See, never let this task dampen your mood. Most of the plant foods come with instructions on product application. So, regardless of whether you opt for a pre-measured spike or pick one that requires mixing with the soil, follow the steps below to feed your plants with the citrus tree fertilizer.

 

Step 1: Pick the best fertilizers for citrus trees. Opt for an organic best citrus food over a synthetic one as the synthetic ones might burn the tree, mainly if the tree is not matured yet.

 

Step 2: Now, measure the quantity of your chosen best citrus fertilizer that you want to give to your plant. The amount of any good citrus fertilizer depends on the age and the size of the plant.

 

For this, you need to follow the steps below:

  1. Measure the tree’s trunk in diameter.
  2. Now, multiply the diameter by 0.10 pounds. This is the nitrogen amount.
  3. Take a quick look at the packaging for your best manure for citrus trees, and try to gauge the NPK numbers. From there, you can get the actual nitrogen amount per pound in the plants.
  4. Next, divide the actual nitrogen that the tree needs to the nitrogen per pound in your chosen citrus tree fertilizer. This is precisely the number that you need to determine the fertilizing that is to be applied.

 

Step 3: Now, take the selected best plant food for citrus trees and evenly start applying it. You have to start the application from a foot away from the tree’s trunk and end right at the drip line. Employ a rake to dig in small homes around the trunk. This can help you evenly spread out the fertilizer.

 

Step 4: Put a bit of compost around the tree and thoroughly water it. In the first year, you need to use about half a pound of 10-10-10 fertilizer for fertilizing the young citrus plants. You need a pound of fertilizer for the mature trees for every year of the citrus plant’s current age.

 

For instance, if the mature citrus is four years old, you will have to scatter four pounds of fertilizer a few feet away from the drip line.
