The first step in growing jackfruit trees from seeds is to select and prepare the seeds for planting. This is important because the quality of the seeds will affect the germination rate, growth rate, fruit quality, and yield of the plants.

To select jackfruit seeds for planting, you need to choose fresh and healthy seeds from ripe and good-quality fruits. You can buy jackfruit fruits from local markets or online stores, or you can harvest them from existing jackfruit trees if you have access to them. You should avoid using old or dried seeds, as they have a low germination rate and may not produce good plants.

To prepare jackfruit seeds for planting, you need to extract them from the fruit pulp and wash them thoroughly. You can use a knife or your hands to cut open the fruit and separate the flesh from the skin. Then you can use a spoon or your fingers to scoop out the edible bulbs that contain the seeds. You should remove any remaining pulp or fibers from the seeds and rinse them with clean water.

To dry jackfruit seeds for planting, you need to place them in a shady and well-ventilated place for a few days until they are hard and dark brown. You can use a paper towel or a cloth to spread them out evenly on a tray or a plate. You should avoid exposing them to direct sunlight or heat sources, as they may damage or kill the seeds.

To store jackfruit seeds for planting, you need to keep them in a cool and dry place until you are ready to plant them. You can use an airtight container or a ziplock bag to store them in a cupboard or a drawer. You should label the container or bag with the date of collection and the variety of the fruit. You can store jackfruit seeds for up to a month at room temperature or up to six months in a refrigerator.

How to Germinate Jackfruit Seeds and Transplant Them into Pots

The second step in growing jackfruit trees from seeds is to germinate the seeds and transplant them into pots or containers. This is important because jackfruit seeds have a low germination rate and take a long time to sprout, so they need to be given the best conditions and care to ensure successful germination and growth.

To germinate jackfruit seeds, you need to soak them in water for 24 hours to soften the seed coat and speed up germination. You can use a bowl or a jar to soak them in clean water at room temperature. You should change the water every 12 hours and discard any floating or damaged seeds.

To sow jackfruit seeds, you need to use moist potting mix or vermiculite in small pots or plastic bags with drainage holes. You can use any potting mix that is suitable for tropical plants, or you can make your own by mixing equal parts of peat moss, perlite, and compost. You should fill the pots or bags with the potting mix or vermiculite and make a hole about 2 cm (0.8 in) deep in the center of each one. You should place one seed in each hole with the pointed end facing down and cover it lightly with the potting mix or vermiculite.

To place the pots or bags, you need to find a warm and sunny place where they can receive at least six hours of direct sunlight per day. You can use a windowsill, a balcony, a greenhouse, or a garden bed as long as they are protected from frost, wind, and rain. You should keep the soil moist but not soggy by watering it every two or three days or whenever it feels dry to the touch.

To monitor the germination process, you need to look for signs of sprouting, such as cracking of the seed coat and emergence of the radicle (root) and plumule (shoot). This may take anywhere from two weeks to two months depending on the seed quality, temperature, and moisture level. You should be patient and gentle with the seeds and avoid disturbing them until they have sprouted.

To transplant jackfruit seedlings, you need to wait until they have two or three true leaves, which are different from the cotyledons (seed leaves) that appear first. This may take another two to four weeks after sprouting. You should prepare larger pots or containers that are at least 20 cm (8 in) in diameter and 30 cm (12 in) in depth. You should also prepare a similar potting mix or vermiculite as before, but you can add some slow-release fertilizer pellets to boost the growth of the seedlings. You should carefully remove the seedlings from their original pots or bags by loosening the soil around them and lifting them gently by their stems. You should avoid damaging their roots or leaves as much as possible. You should plant them in their new pots or containers at the same depth as before and water them well.

How to Care for Jackfruit Seedlings and Plants in Containers

The third step in growing jackfruit trees from seeds is to care for the seedlings and plants in containers. This is important because jackfruit plants are sensitive to frost, drought, pests, and diseases, so they need to be given the proper attention and maintenance to ensure healthy growth and development.

To choose the right containers, you need to consider the size, shape, material, and drainage system of the containers. You should use containers that are large enough to accommodate the growth of the plants, which can reach up to 3 m (10 ft) in height and 2 m (6 ft) in width in containers. You should also use containers that are round or square rather than rectangular or oval, as they provide more space and stability for the plants. You should use containers that are made of plastic, metal, wood, or clay rather than glass or ceramic, as they are more durable and lightweight. You should also use containers that have holes at the bottom or sides for drainage, as jackfruit plants do not like waterlogged soil.

To prepare the best potting mix for jackfruit plants, you need to use a potting mix that is rich in organic matter, well-drained, slightly acidic, and fertile. You can use any potting mix that is suitable for tropical plants, or you can make your own by mixing equal parts of peat moss, perlite, compost, and sand. You can also add some lime or sulfur to adjust the pH level of the potting mix to around 6.0-6.5, which is ideal for jackfruit plants. You should fill the containers with the potting mix up to 2 cm (0.8 in) below the rim and leave some space for watering.

To water jackfruit plants regularly but moderately, you need to water them depending on the weather, season, and soil moisture level. You should water them more frequently during hot and dry periods and less frequently during cold and wet periods. You should also water them more deeply and thoroughly once or twice a week rather than lightly and frequently every day. You should check the soil moisture level by inserting your finger into the soil up to the second knuckle. If it feels dry, you should water it until it drains out of the holes. If it feels moist, you should wait until it dries out a bit before watering it again. You should avoid overwatering or underwatering the plants, as both can cause root rot, wilting, yellowing, or dropping of leaves.

To fertilize jackfruit plants every two or three months, you need to use organic or balanced chemical fertilizers that are high in nitrogen, phosphorus, potassium, and micronutrients. You can use any fertilizer that is suitable for tropical plants, such as 10-10-10 or 20-20-20. You should follow the instructions on the label and apply the fertilizer according to the size and age of the plants. You should also water the plants well before and after fertilizing them to prevent fertilizer burn or salt buildup in the soil.

To prune jackfruit plants lightly and selectively, you need to remove dead, diseased, or damaged branches and maintain a compact and bushy shape. You can use a sharp and clean pair of scissors, shears, or pruners to cut off the unwanted branches at an angle just above a leaf node or a bud. You should prune the plants in late winter or early spring before they start to produce new growth. You should also prune the plants to control their height and width if they become too large for their containers or your space. You should avoid pruning the plants too much or too often, as this can reduce their fruit production and quality.

To protect jackfruit plants from frost, strong winds, excessive heat, pests, and diseases, you need to move them indoors or cover them with blankets or plastic sheets during cold nights, provide them with stakes or trellises for support, shade them from direct sunlight during hot days, inspect them regularly for signs of infestation or infection, and apply natural or chemical remedies as needed. You should monitor the temperature and humidity levels around the plants and keep them between 25-35°C (77-95°F) and 60-80% respectively. You should also look out for common pests and diseases that affect jackfruit plants, such as mealybugs, scale insects, aphids, spider mites, caterpillars, borers, anthracnose, powdery mildew, root rot, etc. You should use organic methods such as neem oil, soap spray, garlic spray, etc. to control them or use chemical methods such as insecticides, fungicides, etc. if necessary.

How to Propagate Jackfruit Trees by Grafting or Air-Layering

how to grow jackfruit seeds

The fourth step in growing jackfruit trees from seeds is to propagate them by grafting or air-layering. This is important because jackfruit trees are difficult to grow from seeds due to genetic variability, low fruit quality, long maturity period, and poor pollination. By propagating them by grafting or air-layering, you can improve the fruit quality and yield of your jackfruit trees and shorten the time to fruiting.

To propagate jackfruit trees by grafting, you need to use scions (cuttings) from desirable varieties and rootstocks (plants) from vigorous seedlings or suckers. You can obtain scions from existing jackfruit trees that produce good-quality fruits or from nurseries or online stores that sell grafted jackfruit plants. You can also use your own jackfruit seedlings or suckers as rootstocks if they are healthy and strong.

To perform different types of grafting techniques, you need to use a sharp and clean knife or pruner to make cuts on the scions and rootstocks and join them together. You can use different types of grafting techniques depending on the size and shape of the scions and rootstocks, such as:

  • Cleft grafting: This technique is used when the rootstock is thicker than the scion. You need to make a vertical cut on the top of the rootstock and split it into two halves. Then you need to make a wedge-shaped cut on the bottom of the scion and insert it into the cleft of the rootstock. You need to make sure that the cambium layers (the green tissues under the bark) of both the scion and the rootstock are aligned.
  • Whip grafting: This technique is used when the rootstock and the scion are of similar thickness. You need to make a diagonal cut on both the rootstock and the scion and match them together. You need to make sure that the cambium layers of both the rootstock and the scion are aligned.
  • Wedge grafting: This technique is used when the rootstock is slightly thicker than the scion. You need to make a vertical cut on the top of the rootstock and split it into two halves. Then you need to make a diagonal cut on both sides of the bottom of the scion and insert it into the cleft of the rootstock. You need to make sure that at least one side of the cambium layers of both the scion and the rootstock are aligned.
  • Side grafting: This technique is used when the rootstock is much thicker than the scion. You need to make a horizontal cut on the side of the rootstock and remove a thin slice of bark. Then you need to make a wedge-shaped cut on the bottom of the scion and insert it into the cut of the rootstock. You need to make sure that the cambium layers of both the scion and the rootstock are aligned.

To care for grafted jackfruit trees, you need to wrap the graft union with tape or plastic wrap to prevent water loss and infection. You also need to keep the soil moist but not wet by watering it every two or three days or whenever it feels dry to the touch. You also need to remove any shoots or suckers from the rootstock that may compete with the scion for nutrients and water. You also need to protect them from pests and diseases by inspecting them regularly and applying natural or chemical remedies as needed.

To propagate jackfruit trees by air-layering, you need to use branches from healthy and mature plants. You can use any branch that is at least 1 cm (0.4 in) in diameter and has several nodes (the points where leaves or buds emerge). You should avoid using branches that have flowers or fruits, as they may reduce rooting success.

To perform air-layering technique, you need to use a sharp and clean knife or pruner to make a ring of bark around the branch about 15-20 cm (6-8 in) below a node. You should remove all the bark and cambium layer from that area, exposing the white wood underneath. Then you need to apply rooting hormone (a powder or gel that stimulates root formation) on that area and cover it with moist sphagnum moss or peat moss. Then you need to wrap that area with plastic wrap or aluminum foil and secure it with tape or wire.

To care for air-layered jackfruit trees, you need to keep the moss moist by spraying it with water every two or three days or whenever it feels dry to the touch. You also need to check for root formation by peeking through a small hole in the plastic wrap or foil. This may take anywhere from two months to six months depending on the branch size, season, and temperature. When you see enough roots filling up the moss, you need to cut the branch below the roots and plant it in a pot or container with a similar potting mix or vermiculite as before.

How to Harvest and Enjoy Jackfruit Fruits

The fifth and final step in growing jackfruit trees from seeds is to harvest and enjoy the fruits. This is the most rewarding and satisfying part of the process, as you get to taste the fruits of your labor and share them with your family and friends.

To determine the ripeness and readiness of jackfruit fruits, you need to consider the variety, size, color, smell, sound, and feel of the fruits. Different varieties of jackfruit may have different ripening times and indicators, so you should consult the source of your scions or plants for more information. Generally, jackfruit fruits are ready to harvest when they reach their full size, which can range from 30 cm (12 in) to 90 cm (35 in) in length and 15 cm (6 in) to 50 cm (20 in) in diameter. They also change their color from green to yellow or brown when ripe. They also emit a strong and sweet aroma that can be smelled from a distance. They also make a hollow sound when tapped lightly with a finger or a knife. They also feel slightly soft when pressed gently with a hand.

To harvest jackfruit fruits carefully and safely, you need to use gloves, knives, scissors, or saws. You should wear gloves to protect your hands from the sticky latex sap that oozes out of the fruit skin and stem. You should use knives, scissors, or saws to cut off the fruit from the branch or trunk, leaving about 10 cm (4 in) of stem attached to the fruit. You should be careful not to injure yourself or damage the fruit while cutting it. You should also be prepared to catch or support the fruit as it falls down, as it can be very heavy and bulky.

To store jackfruit fruits properly, you need to keep them either whole or cut in a cool and dry place or in a refrigerator or freezer. You can store whole jackfruit fruits for up to a week at room temperature or up to a month in a refrigerator. You can also cut jackfruit fruits into smaller pieces and store them in airtight containers or ziplock bags for up to three days in a refrigerator or up to six months in a freezer.

To prepare and eat jackfruit fruits in different ways, you need to cut open the fruit and separate the flesh from the skin and seeds. You can use a knife or your hands to cut open the fruit along its natural segments and peel off the skin. Then you can use a spoon or your fingers to scoop out the edible bulbs that contain the seeds. You can also remove the seeds by cracking them open with your teeth or a nutcracker and eating the white kernel inside. You can eat jackfruit fruits raw or cooked in various dishes, such as salads, curries, pies, cakes, ice creams, jams, juices, etc.

Here is an example of a simple and delicious jackfruit salad recipe that you can try:
