Best Fertilizer for Guava Trees: Homemade, Liquid, Organic, Natural, and Compost Manure

All plants perform best when they get the right amount of nutrients. Guava trees need nutrients more than the average plant. Guava trees need high-intake fertilizers of nitrogen, phosphorus, potash, and some magnesium to produce more and more fruits. Composting and supplementing the soil with nutrients are different ways to make a common land more agriculturally valuable soil. Let’s check out the best fertilizer for guava trees.

Adding fertilizer to the soil helps in increasing the amount of soil nitrogen, phosphorus, potassium, manganese, iron, and copper. And these are the most important nutrients required for Guava trees for proper growth and fruit production. In tropical climates, the Guava tree produces fruit twice a year. The Guava tree needs high fertilization due to heavy fruits. The maturity of plants will also increase the fertilizer requirements.

In the growing season, it needs nitrogen and phosphorus-rich manure. In fruit season, it needs potassium-rich fertilizer. In a pot plant, you should not use chemical fertilizers. Because our potting is not able to withstand the regular use of salt or chemical fertilizers collected in the soil it affects our potting mix and plant, and finally, dies due to root rot. That is why you should only use organic fertilizer.

Organic fertilizers for the Guava tree

Organic fertilizer can be made from leftover foods and clippings in the home, which also makes it cost-free. The most common ingredients used to make a home include cottonseed food, alpha-food, or fish emulation for nitrogen. And rock phosphate or bone meal is used to provide phosphorus. Though kelp meal or granite meal is used to deliver potassium. The problem with organic fertilizer is that fertilizer slowly does.

Natural fertilizers for Guava tree

You can use waste products from animals such as cow dung, eggshells, and burnt ash.
Add a layer of powdered egg peel under the plant soil. Break the egg peel into large enough pieces to cover the drainage holes. Cover the holes so that egg peels also prevent the soil from falling from the bottom.
Wood ash can be placed around Guava trees. Wood ash is a great addition to fruit trees, due to its properties. Wood ash holds 3% of potassium. Potassium is a major nutrient of plants associated with flowers and fruits.

Compost manure for Guava tree

The Guava tree needs to decompose the manure first in the soil before nutrients are available. It is a limited element of organic fertilizer but once the fertilizer is rotten, the Guava tree or any plant fed with this type of fertilizer can access a high amount of nutrients for a very long time. Further, organic fertilizer swells the biological activities of the living organisms in the soil and adds agricultural value to the soil.

Find 6 feet square space in your backyard to make a pile of manure. Choose a flat place, that has some sun, and is properly close to the kitchen. Outline the area with bricks, cement blocks, or logs if you wish. Pile up 6 inches of dry grass, dead leaves, or other similar dry plant products in the area. Flatten it as soon as you add it, so it doesn’t get mounded. Put 3 inches of horse, cow, sheep, or goat manure on top of dry material. Add another 3 inches of other green matter like vegetable peels. Water the compost pile well and combine the layers into each other with a rake or pitchfork.

Repeat this process, even add layers of dry material and wet material, fertilizer does not make up more than 50% of the wet material. Water the pile thoroughly every three weeks and turn the material over frequently. When the pile is 6 feet high or you want to use it two months in advance, stop adding new layers whenever it comes first. Continue to turn the compost pile every week to add air to the mix. Start using compost as fertilizer when its structure becomes dry and broken and does not produce any heat.

Homemade fertilizers for Guava tree

Measure 1/4 cup of Epsom salt, 2 cups of urine, and 2 cups of wood ash. Place these ingredients in a 5-gallon bucket and mix well. Add green weeds and grass clippings to make half of the bucket. Fill the bucket with water. Place this bucket in a separate place and let it stand for three days. After three days, bring out the bucket and train the tea in another container using a strainer.

You need to dilute the tea with 50 percent water to reduce concentration when you want to feed your Guava trees. Then, apply this homemade compost around the soil around your Guava trees. Wood ash should be free of charcoal and fluid. Stand the mixture for just three days. Steeping for more than three days can produce yeast and is bad for your Guava tree.

Liquid fertilizers for the Guava tree

Seaweed extract

It provides important nutrients to plants. Take 5 ml seaweed extract and mix it in 1 liter of water. Spray this solution to the entire plant every month.

Epsom salt

The second liquid fertilizer is 19:19:19 and Epsom salt is also known as magnesium sulfate. Both of them are chemical fertilizers. Take one tablespoon of each fertilizer and mix it in a liter of water. Spray solution on the whole plant every month. Use this fertilizer after 2 weeks of using the seaweed fertilizer.

Commercial fertilizers for Guava tree

Inorganic fertilizer is also known as synthetic fertilizers or commercial fertilizers. This type of fertilizer is produced from synthetic chemicals containing calculated amounts of concentrated nitrogen, potassium, and phosphorus. After feeding this type of manure, the Guava tree supplements quickly with the required nutrients.

However, there are many downsides to inorganic fertilizer, and including it does not improve soil quality and biological activities of soil organisms. Moreover, when Guava trees are supplemented with too much inorganic fertilizer for a long time, fertilizer can lead to poor growth of Guava. The most well-known non-organic fertilizers for Guava trees include 6-6-6-2, 6-6-6-4, 8-8-8-2 (Nitrogen-Phosphorus-Potassium-Magnesium). 8-8-8 (Nitrogen-Phosphorus-Potassium).

Fertilizer’s schedule

Commercial fertilizers

The Guava tree is usually fed in two importantly different ways and includes foliar spray and root or ground application. In the form of a foliar spray, fertilizer spray is done on the leaves of Guava trees which dissolve into the water. This form of fertilizer feeding makes nutrients available immediately when sprayed by Guava trees.

However, the foliar spray is commonly used by farmers who want to supplement their Guava orchard with extra nutrients like zinc, copper, and manganese. If you are using a foliar spray, your Guava tree needs to be supplemented once every two months. Other best agricultural practices using foliar spray include: Avoid spraying your Guava trees more than once in two months.

Secondly, do not spray too much-concentrated fertilizer on your Guava. You need to dissolve 0.4 liters of fertilizer in water when your Guava plant is under one year old. And Guava is well grown, you can dissolve up to 1 liter in water. Root/ground application includes composting Guava with nutrients from earth or root level. This method of feeding Guava is somewhat of a limitation.

This is because nutrients have to be absorbed from the roots and then move to stem branches and leaves. And this delays the distribution of nutrients into important parts like reproductive structure. However, root application is also a good way to feed plants as it improves not only the plants but also the soil around the plant.

Nutrients such as nitrogen, potassium, phosphorus, and magnesium are applied in the form of 6-6-6-4, 6-6-6-4, and 8-8-8 fertilizers around the Guava tree 30 centimeters from the stem. Divide the fertilizer evenly using a garden rake around the Guava tree and surrounding soil. Gently rake the soil and slowly add water to keep the surrounding soil moist.

Organic fertilizers

You have to decompose the cow dung manure and vermicompost thoroughly each amount of 500 grams. Also take 3 more items in every quantity 100 g of Mustard cake powder, Neem cake powder, and Bone meal Mix all these things well. Spray this organic mixture on the potting soil of the plant stem. You can see that the soil on the upper layers has fibrous roots of plants.

These roots will absorb essential nutrients from this organic compound. You have to use this organic mixture 4 times every year after 3 months. You will have to use this fertilizer between February and March for the first time, from May to June for the second time, from August to September for the third time, and for the last fourth time from November to December.

After applying this fertilizer add 2 to 3 inches of mulch. You can use dry leaves, wooden chips, coco-coir, or rice husk for mulching. After adding the mulch, place a piece of broken pot that will prevent flying over the mulch through strong winds. Finally, after watering it all deeply to the plant.

Fertilizers for increasing the Guava yield

To increase production Spray urea 1% and Zinc sulfate 0.5% twice a year during March and October. Good quality fruits can be obtained with increased production by adding 600 grams per plant of Neem cake to Guava. 40 kg vermicompost with 40 kg of cow dung or 100 g of organic fertilizers can increase production with good quality fruits.

Apply manure 2 to 3 feet away from the main stem. Compost and fertilizers should be used on a soil testing basis. Continue irrigation at intervals of 10 to15 days. Irrigate the crop once a week during flowers and fruit.

How to fertilize Guava in pots

Guava roots are shallow and absorb water and nutrients faster. Make sure to use a high-quality organic potting soil mix in your Guava containers. Gardening soil or seed starting soil is not ideal for pottery plants. The Guava tree is a heavy feeder, so it should be composted every 1 to 2 months when it is young, then 3 to 4 times a year.

Guava trees need high-intake fertilizers of nitrogen, phosphorus, potash, and some magnesium to produce more and more fruits. Mix 6-6-6-2 manure in the soil at the beginning of the growing season and then 3 to 4 times during the growing season. In the growing season, Feed Guava with a weak liquid fertilizer, but stop feeding during the winter months.

High fertilizer in potassium is the best fertilizer for Guava trees to increase fruit production. Feed Guava trees with liquid fertilizers in the growing season. Guava trees fall short of iron in alkaline and high pH soil. Fertilize with iron sulfate 1 to 2 times every year. Always water your Guava tree after fertilizing to diminish burn risk.
