Best Fertilizer for Jackfruit Tree: Organic, Compost, Homemade, Liquid, NPK, How and When to Apply

The Jackfruit trees prefer nutritious soil with excellent drainage. They are not overly picky about soil pH, although they grow best in slightly acidic soil. The soil used for planting a Jackfruit tree should be fertile and soft. The Jackfruit tree thrives in the rich, deep soil of medium or open structure, sometimes on deep gravel or laterite soil. It cannot tolerate wet feet. If the roots touch the water, the tree will not bear fruit or may die. Let’s check out the best fertilizer for Jackfruit tree.

Fertilizing the Jackfruit tree will give it the nutrients it needs to grow and produce fruits. Fertilizing also helps in improving soil quality which is beneficial for future crops. By fertilizing Jackfruit, you can increase production and improve the overall health of your garden. Fertilizers provide nutrients such as potassium, phosphorus, and nitrogen to crops that allow crops to produce larger, faster, and more food. By delivering nutrients like nitrogen, fertilizer helps plants thrive despite the risk of weeds and disease.

Organic fertilizers like fertilizers improve soil fertility by feeding microorganisms in the earth, reducing erosion, and keeping soil well hydrated. Lack of proper nutrients affects tree growth and fruit production. Soil analysis can determine other nutrients required for fruit trees. Applying nutrients that are not necessary can cause nutritional imbalances.

Compost manure for Jackfruit

Vermicompost – Vermicompost is the best fertilizer for growing Jackfruit plants. Fertilizing the Jackfruit plant with vermicompost increases the fertility of the soil.

Compost – Choose an ample open space in your garden that receives the full sun, cleans weeds, and digs a hole. To ensure good drainage, mix 1/3 of compost, sand, and organic matter in garden soil to produce rich, porous potting soil for planting.

Manure – Manures should be spread in the basin and mixed with soil through spading. Applying a good amount of farmyard manure helps the tree grow well and produce better.

Liquid fertilizers for Jackfruit

Compost tea also protects your tree surfaces by covering them in beneficial organisms that prevent harmful microorganisms. The improved growth is also due to increased nutrients delivered to the plant and maintained soil. Fish emulsion and rock powder are some organic fertilizers you can use on fruit trees.

Homemade and organic fertilizers for Jackfruit

Wood ash has 40 to 45 percent calcium carbonate, making it an excellent alternative to lime in offering more alkaline to the soil to grow a good fruit tree. Wood ash is high in calcium and is about half as effective as lime in making acidic soil ineffective. Check your soil pH level every year or two years. Ash is an effective way to increase soil pH if it is too acidic.

Mix 1/2 kg goat dung, 1 kg cow dung, 1 kg peanut cake, 1/2 kg neem cake, 500 grams chicken waste, bone meal, wood ash, 50 grams pseudomonas. Mix and apply an equal amount of cocopeat and mud. Repeat the procedure every three months.

Natural fertilizers for Jackfruit

Mulching the Jackfruit trees helps maintain soil moisture, reduce weed problems adjacent to the tree’s trunk, and improve soil near the surface. Mix with 2 to 6 inches of bark, wooden chips, or similar mulch material. Place the mulch from the trunk 8 to 12 inches.

Commercial fertilizers for Jackfruit 

When choosing fertilizers for your Jackfruit trees, you would like to select the proportion of NPK best suited for fruit plants. The Jackfruit needs enough fertilizer for good growth and production. Both chemical and organic fertilizers are recommended. Fertilize your Jackfruit with nitrogen, phosphorus, potassium, and magnesium applied at the age of six months to two years in the ratio of 8:4:2:1 to 30 grams per tree and doubles every six months.

Before the tree reaches the two-year mark, you can use 4:2:4:1. Potassium content should be high to encourage fruiting in fertilizer formation from the 4th year. However, if you are experiencing problems with high botanical growth or fruit drop, you may need to use more nitrogen fertilizer for the Jackfruit tree. Low nitrogen fertilizers can be used when you are trying to promote flowers and fruits.

Always read your chosen fertilizer label to ensure that it is appropriate for use on fruit trees. The Foliar application has proved to be a great way to provide plant requirements for secondary nutrients (calcium, magnesium, sulfur) and micronutrients (zinc, manganese, iron, copper, boron, and molybdenum).

Jackfruit fertilizer schedule

Fertilize the Jackfruit trees twice a year in spring and fall with slowly released granule fertilizer. Adding compost annually to the soil around the tree can also be beneficial. The best time to fertilize before new growth begins is in spring. In summer, you can also give a fertilizer if your tree is not growing well. Adding fertilizer in the fall can help improve winter hardiness. The best way to fertilize is to broadcast fertilizer evenly throughout the area under the tree canopy.

You can also make a ring around the tree trunk with fertilizer. Be sure not to find anything on leaves or fruits, as it can burn them. Iron sulfate for trees in acid to neutral soils applies 2 to 4 times annually on the ground from 7 to 28 grams per tree. Apply chelated iron to the soil once or twice a year on each tree. Iron applications are most effective from May to September, and foliar sprays from April to September.

Newly planted trees need a different ratio of fertilizers compared to mature Jackfruit trees, so you would like to use a fertilizer with an 8:4:2:1 ratio of nitrogen, phosphorus, potassium, and magnesium for the first two years. You should start with 30 grams of fertilizer, but the following three times double the amount you used last time. Therefore, the second, third, and fourth applications should be 60,120, 240 grams. Further, consider applying foliar fertilizer for two weeks. Foliar feeding means making nutritious liquid and then spraying it on tree leaves.

Jackfruit plants absorb nutrients through their leaves as well as their roots. Thus, feeding them at root and leaf levels increases their nutrient absorption faster. Once your Jackfruit tree is two years old, you can switch to the fertilizer formula with a ratio of 4:2:4:1 and use a full kilogram at a time. Water it immediately to help soak it and reach the roots quickly. Feed it with 8-3-9 fertilizers following the manufacturer’s direction for quantity and rate when the plant starts blooming.

How to fertilize Jackfruit in pots

Growing Jackfruits at home requires a lifetime of commitment from the beginning; it needs space, water, warmth, and care to grow in a large tree. The Jackfruit tree is quickly grown in containers but chooses large containers for its root development. Be aware that drainage in these containers should also be good. You can use well-draining soil such as peat moss, as it retains moisture very well and is light enough to move the seed in the soil. Feed with a weak liquid fertilizer weekly.

These plants don’t need food, but tiny plants need regular fertilizer. Heavy mulch should be all around the plant when the temperature is relatively low in winter. Use fertilizer 8:4:2:1 that has nitrogen, phosphorus, potassium, and magnesium. Spread the fertilizer around the tree’s base, 20 inches from the stem. Then water it. Every six months, fertilize your tree, and it will start bearing fruit within 3 to 4 years.

Why are my Jackfruit tree leaves turning yellow?

The leaf color turns yellow due to a lack of iron, manganese, and magnesium in Jackfruit trees. Sometimes the fertilizers used in trees also contain herbicides that cause the leaves to turn yellow and thick. Lack of nutrients is common in trees growing in excessive alkaline or poorly drained soil.

Can Jackfruit grow in cold weather?

The Jackfruit tree cannot withstand frost and drought, yet it is a hardy tree that can withstand extreme temperatures. A mature tree can withstand up to 47°C heat, and if acclimated, the temperature is about 0°C cold for a short time.

How big does a Jackfruit tree grow?

The Jackfruit tree is a medium-sized evergreen that grows between nine and 20 meters. The fruit is the largest tree-growing fruit globally, with the potential to weigh up to 50 kg of certain varieties, although they usually weigh between 5 and 15 kg.
