How to Grow Jujube Tree: Propagation From Seeds, Cuttings, and Grafting

Jujube trees, also known as Chinese dates, are popular fruit trees native to China. They have been cultivated for thousands of years and are now grown in many parts of the world. If you’re interested in growing your jujube tree, there are several methods of propagation you can choose from: seeds, cuttings, and grafting.

How to Grow Jujube Tree

Jujube Trees Overview

These trees typically grow to 20 to 40 feet and have a spreading crown with a diameter of about 15 to 30 feet. The leaves are small, oval-shaped, and shiny, providing an attractive backdrop for the clusters of fruits that adorn the tree. The flowers are inconspicuous and bloom in early summer, forming small green fruits that turn reddish-brown as they ripen. Jujube fruits are small, round, and usually about the size of a cherry. They have thin, edible skin and crisp, white flesh surrounding a single seed.

Growing Jujube Trees from Seeds

Seed Preparation: Before sowing the seeds, it is advisable to soak them in water for 24 hours. After soaking, gently rinse the seeds to remove any remaining debris.
Seed Planting: Fill a seed tray or small pots with a well-draining potting mix. Place the jujube seeds on the soil’s surface and cover them with a thin layer of potting soil mix.
Germination: Jujube seeds typically germinate anywhere from 2 to 6 weeks. The ideal temperature for successful germination of jujube seeds is between 20-30°C. If planting outdoors, select an area that receives direct sunlight throughout the day.
Seedling Care: Place the seedlings in a well-lit area, preferably near a window where they can receive sunlight for at least 6 hours daily.
Transplanting: After the seedlings have grown to around 6 inches (15 cm), they can be transplanted into larger pots or the ground. Choose a sunny location with well-draining soil.

Propagating Jujube Trees Through Cuttings

Choose a mature, disease-free branch about 1/4 to 1/2 inch in diameter. Ensure the branch has several nodes, the points where leaves are attached.
Make a clean cut at a 45-degree angle below a node using the sharp pruning shears.
Remove any leaves from the lower half of the cutting, leaving only a few leaves at the top for photosynthesis.
Dip the bottom end of the cutting into rooting hormone powder to encourage root growth. Gently shake off any excess powder.
Fill a small container or pot with potting soil that drains well. Insert the cutting into the soil, ensuring at least two nodes are buried beneath the surface.
The potted cutting should be placed in a warm, bright location, away from direct sunlight.
After that, cover the pot with a plastic bag to create a mini greenhouse effect.
Once the cutting has developed a root system, it can be transplanted into a larger pot or directly into the ground.

Grafting Techniques for Jujube Tree Propagation

Whip-and-Tongue Grafting

Whip-and-tongue grafting is a popular grafting technique for jujube trees. It involves making a diagonal cut on the scion and rootstock, followed by a vertical cut to create a tongue shape. The scion and rootstock are joined together, ensuring the cambium layers align. This technique provides a strong connection and is commonly used for grafting jujube trees.

Bark Grafting

Bark grafting is used for jujube tree propagation when the rootstock is larger. It involves making a vertical cut on the rootstock and removing a section of bark. The scion, prepared with a matching wedge shape, is then inserted into the exposed cambium layer of the rootstock. This technique provides a good connection and is suitable for grafting onto older jujube trees.

Selecting the Right Seeds for Jujube Tree Propagation

Freshness: It is ideal to choose fresh seeds recently harvested. Fresh seeds have a higher viability and are more likely to germinate successfully.
Source: Obtain seeds from a reliable source, such as a reputable nursery or a trusted jujube tree grower. This ensures that the seeds are of good quality and are true to the desired jujube tree variety.
Size: Select seeds that are plump and of average size. Seeds that are too small may indicate poor quality or low viability.
Shape: Look for seeds that have a well-formed shape and are free from any deformities or abnormalities. Seeds with irregular shapes may have reduced viability.
Color: Choose seeds that have a uniform color. Avoid seeds that are discolored or have any signs of mold or disease.

Preparing Seeds for Germination

Cleaning: Start by cleaning the seeds to remove any dirt or debris. Rinse them gently under running water and pat them dry with a clean cloth.
Soaking: Some jujube seeds benefit from soaking before planting. Place the seeds in a bowl of room-temperature water and let them soak for 24 hours. This can soften the seed coat and improve germination rates.
Scarification: Jujube seeds have a hard outer seed coat that can inhibit germination. To overcome this, you can scarify the seeds by gently rubbing them with sandpaper or nicking them with a knife. This helps to break the seed coat and allows water to penetrate, promoting germination.

Creating Optimal Conditions for Jujube Seed Germination

Temperature: Jujube seeds germinate best at temperatures between 20°C-30°C. Maintain a warm and consistent temperature throughout the germination process.
Moisture: Keep the seeds consistently moist but not overly wet. Use a well-draining seed-starting mix and water the seeds gently to avoid waterlogging.
Light: Jujube seeds do not require light for germination. Keep them in the dark and warm location until they start to sprout.
Time: Jujube seeds can germinate anywhere from a few weeks to a few months. Be patient and monitor the seeds regularly for signs of germination.

Caring for Jujube Seedlings

Caring for Jujube Seedlings is crucial to ensure their healthy growth and development. Here are some important tips to help you nurture these young plants. First, provide them with well-draining soil that is rich in organic matter. Regularly water the seedlings, keeping the soil moist but not overly saturated. Apply a layer of mulch around the seedling’s base to help retain moisture and suppress weed growth.

Prune the seedlings to maintain a balanced shape and remove damaged or diseased branches. Finally, protect the seedlings from extreme temperatures and provide adequate sunlight. With proper care, your Jujube Seedlings will thrive and flourish. Regularly monitor the seedlings for pests and diseases, and take appropriate action if any issues arise.

Transplanting and Establishing Jujube Trees

A jujube seedling can be transplanted into its permanent location once it has reached the appropriate size. Ensure well-draining soil and a sunny spot for transplanting. You will need to dig a hole that is large enough to accommodate the root system of the seedling. Place the seedling in the hole after gently removing it from its container, taking care not to disturb the roots.

Firm the soil gently around the seedling after backfilling the hole. Soil needs to be thoroughly watered to settle the newly transplanted tree. Watering and maintaining jujube trees regularly after they are established is necessary. Once a week, water the trees deeply. To conserve moisture and control weed growth, apply organic mulch around the tree’s base. During the dormant season, prune the trees to remove dead, damaged, overgrown, and diseased branches and promote healthy growth.

Conclusion

Following these propagation methods, you can successfully grow jujube trees and enjoy their delicious fruits. Remember to provide proper care and maintenance as the trees grow, including regular watering, fertilizing, and pruning. Happy growing!
