Fertilizers For Guava Tree And Guide For Application

fertilizer for guava tree

In this article, we are going to be looking at different forms of fertilizers for guava trees plus how to feed guava with them for optimal growth.

Short answer: the best-known fertilizers for guava are 6-6-6-4, 8-8-8-2, and 8-8-8 fertilizers. Young guava can be fed after every two months while well-grown guavas are usually fed one in a year. The fertilizer is applied evenly on the ground around the guava tree.

Overview

By definition, anything that can make the soil more fertile and productive can be termed as fertilizer. Composting and supplementing the soil with nutrients are different ways of making an ordinary land into more agriculturally valuable soil.

Adding fertilizer to the soils helps increase the nitrogen, phosphorus, potassium, manganese, iron, and copper content of the soil.

And these are the most important nutrients required by guava trees for proper growth and fruit production.

Despite, fertilizing your plants may not be the exciting part of your gardening, it is important to know that having a simple understanding of fertilizer management is required for growing a healthy plant.

Knowing the basic fertilizer application can help you grow a large, strong, and healthy guava plants without the need to break your bank.

There are basically two forms of guava fertilizers:

  • Organic guava fertilizer
  • Inorganic guava fertilizer

Organic Fertilizer for Guava

This is a form of fertilizer made from organic matters. It is also called organic compost or compost manure.

Fertilizing your guava orchard with compost manure is an inexpensive and effective farming practice that can help increase the activities of soil microorganisms such as earthworms that are known to improve the productivity of the soil and help quicken the growth process of your guava plant.

Organic fertilizer can be made at home from left-over foods and clippings, which also make it cost-free. The most common ingredients employed for making homemade are cottonseed meal, alfalfa meal, or fish emulsion for nitrogen. And rock phosphate or bone meal are used to provide phosphorus. While kelp meal or granite meal is used to provide potassium.

You can use waste products from animals such as cow dunks, eggshells, and burned ashes. The problem with organic fertilizer is that the compost does slowly. The manure needs to be decomposed first into the soil before the nutrients become available to the guava plant.

This is the limiting factor of organic fertilizer but once the manure is decomposed, the guava plant or any plant that is fed with this type of fertilizer can get access to a high amount of nutrients for a very long period of time.

Moreover, organic fertilizer also adds agricultural value to the soil by increasing the biological activities of the organisms living in the soil.

Inorganic Fertilizer

Inorganic fertilizer is also known as chemical or synthetic fertilizer. This type of fertilizer is produced from synthetic chemicals that contain a calculated amount of concentrated nitrogen N, potassium K, and phosphorus P.

This type of fertilizer quickly supplements the guava plant with the required nutrients after feeding. However, inorganic fertilizer has many downsides and include: it does not improve the soil quality and biological activities of soil organisms. Moreover, when guava trees are supplemented with too much inorganic fertilizer for a long time, the fertilizer may lead to poor guava growth.

The best known inorganic fertilizers for guava trees include:

  • 6-6-6-2 (nitrogen-phosphorus-potassium-magnessium)
  • 6-6-6-4 (nitrogen-phosphorus-potassium-magnessium)
  • 8-8-8-2 (nitrogen-phosphorus-potassium-magnessium)
  • 8-8-8 (nitrogen-phosphorus-potassium)

How to Make Homemade fertilizer for guava tree

Organic fertilizer can be made at home with simple waste ingredients.

What you need:

  • 5 gallon bucket
  • Cup
  • Epsom salt
  • Cow urine
  • Wood ash
  • Grass clippings
  • Green weeds

Direction

Measure out ¼ cup of Epsom salt, 2 cups of urine, and 2 cups of wood ash. Place these ingredients into the 5-gallon bucket and mix thoroughly. Add the green weeds and grass clippings to make half of the bucket.

Fill the rest of the bucket with water. Keep this bucket in a separate place and allow it to steep for three days. After three days, bring out the bucket and train the tea using a strainer into another container.

You need to dilute the tea with 50% of water to reduce the concentration when you want to feed your guava trees. Then, apply this homemade fertilizer around the soils surrounding your guava trees.

Precaution

The wood ash should be free from charcoal and fluid

Steep the mixture for only three days. Steeping for more than three days can lead to fermentation and this is bad for your guava plants

It is also recommended to finish the concentrate within two days.

Guava Fertilizer Guide

Guava plants are fed once a month when are young. The dosage that is recommended to fertilize your guava plants during this stage year is half-pound (8oz ) the first year.

When your guava trees are so established or well grown on the ground, you can feed your guava trees 3 to 4 times in a year. The dosage of inorganic fertilizer that is between 1 to 2 pounds {16-32).

You can supplement your guava with copper and zinc. Guava is required to be fed with copper and zinc 3 times through spring to summer using a foliar spray.  This is expected to be done during the first 2 years of guava growth and one time a year after 2years.

If the  PH  of the soil surrounding your guava tree becomes very high or alkaline. You need to timely drench the soil with chelated iron. This can be applied around the base of each guava tree to help decrease the soil PH level.

Different Ways Guava can be Fertilized

The guava tree is usually fed in two main different ways and include Foliar spray and root or ground application.

In the case of foliar Spray, the leaves of guava trees are sprayed with fertilizer that is dissolved in water. This form of fertilizer feeding makes nutrients available to guava plants immediately when sprayed.

However, the foliar spray is usually employed by farmers who want to supplement their guava orchard with additional nutrients such as zinc, copper, and manganese. Your guava tree is needed to be supplemented once every two months if you are using the foliar spray. Learn more

Other best agricultural practices while using foliar spray include: avoid over spraying your guava trees typically more than one time in two months. Secondly, do not spray your guava with over concentrated fertilizer. You need to dissolve 16 ounces in the water when you are less than one year old. And the guava is well grown, you can dissolve up to 32 ounces in water.

Root /ground application involves fertilizing guava with nutrients from ground or root levels. This method of feeding guava hs some limitations. This is because the nutrients have to be absorbed by the roots and then move to the trunks, branches, and leaves. And this causes delays in distributing the nutrients to important parts such as reproductive structures.

However, root application is also a good method of feeding plants as it does not only improve the plant but also the soil surrounding the plant.

Nutrients such as nitrogen, potassium, phosphorus, and magnesium in the form  6-6-6-4, 6-6-6-4, and 8-8-8 fertilizers are applied around the guava plant 30cm away from the trunk. Distribute the fertilizer evenly using a garden rake around the guava tree and the surrounding soils. Rake the soil gently and slowly add water to keep the surrounding soil moist.

What is the Best Fertilizer for Guava Tree?

  • 6-6-6-2 fertilizer
  • 8-8-8 fertilizer

What do I Feed my Guava Tree?

Fertilize your guava tree every 2 months with 6-6-6-2 fertilizer in order to encourage healthy soil, guava growth, and fruit production.

Whatkind of Fertilizer do Trees need?

Basically, guava trees like any other flowering plants require appropriate nitrogen, potassium, phosphorus, and manganese in the correct proportion.

Does Guava Tree need a lot of Water?

Guava grows well under full sunlight. it can survive dry summer without water, however, guava tends to do well with timely watering. If you watered your guava, you need to allow the ground to dry to some inches before you rewater your guava trees again.
