How to Grow Asparagus Fern (Wen Zhu)? Three Differences Between This Asparagaceae Climbing Plant and Yun Zhu

Wen Zhu (Asparagus Fern) is a climbing plant in the Asparagaceae family. With its light, graceful form and elegant poise, it can add a touch of scholarly refinement when placed in living rooms, studies, and other spaces, which is why it carries the meaning of “the refined bamboo” and is a plant of exceptionally high ornamental value. So, how do you grow Asparagus Fern?

1. Introduction to Wen Zhu

1. Is Wen Zhu a bamboo?

Wen Zhu is not a bamboo. It is only because its leaves are soft and light, evergreen all year round, and its stems have nodes and resemble bamboo in appearance, with a refined and elegant posture, that it is named Wen Zhu (refined bamboo). Although it has bamboo-like stems, it is completely different from bamboo.

2. Does Wen Zhu bloom?

Wen Zhu can bloom, usually after 4-5 years of cultivation. The flowering period is September to October, and the flowers are white with green in the center, about the size of a button, and unscented. Two to three months after flowering, it produces small berries.

2. How Do You Grow Wen Zhu?

1. Propagation: by seed or division.

Seed propagation is best done in spring, in March-April. The method is to rub off the fruit skin of the Wen Zhu, wash the seeds clean, dry them, and then sow them. They will sprout 30-40 days after sowing. Division propagation is best done in spring. Take a Wen Zhu that is more than 3 years old and use a sharp knife to divide the clustered stems and roots into 2-3 clumps, each with 3-5 buds, then pot and plant them separately.

2. Soil: sandy loam rich in humus.

Wen Zhu likes loose, fertile soil and also has fairly high requirements for drainage, so you can choose a sandy loam rich in humus for cultivation.

3. Temperature: between 15°C-25°C.

Wen Zhu likes a warm environment and is not tolerant of severe cold. The suitable temperature for growth is 15°C-25°C. When the summer temperature is above 32°C, it stops growing, and when the winter temperature is below 5°C, it suffers cold damage. In winter, the temperature is best kept above 10°C.

4. Light: a place with diffused light.

Wen Zhu likes a semi-shaded environment and should not be exposed to direct sunlight. It is best kept in a place with diffused light. In early spring and autumn, when the sunlight is not strong, it can be placed in a sunny spot indoors. In winter, place it in a sunny spot, and in summer, place it in a cool place away from direct sunlight or in a spot with diffused light indoors.

5. Watering: follow the principle of “dry then wet.”

Wen Zhu is not tolerant of drought and is also afraid of waterlogging. Watering should follow the principle of “dry then wet”: do not water when dry, and water thoroughly when you do. If you water too much and the potting soil is too wet, it easily causes root rot; if you water too little and the potting soil remains dry for a long time, it easily causes yellowing leaf tips. In summer, water once every 2 days, and also sprinkle water on the ground and rinse the branches and leaves with clean water. In spring and autumn, water once every 3-5 days. In winter, reduce the amount of watering. When watering, the water temperature should be as close as possible to the surrounding temperature.

6. Fertilizing: light fertilizer, applied frequently.

Wen Zhu relatively likes fertilizer. Fertilizing should be light and frequent, and concentrated fertilizer must not be applied. In spring and autumn, apply a fully rotted, dilute organic liquid fertilizer once every half month. Stop fertilizing in summer and during the winter. Once the plant has taken shape, appropriately control fertilizing to avoid excessive growth and long trailing vines that affect the beauty of the plant's form.

7. Pruning: prune in time.

Wen Zhu should be pruned in time to remove overly dense branches. Every March to April, repot old Wen Zhu plants. Before repotting, prune excess root suckers or divide the clump, and also pay attention to tying and staking to maintain a form with an even balance of density and openness.

8. Pests and diseases: spray pesticides for control.

A disease Wen Zhu is prone to is leaf blight, which is caused by excessive humidity and poor ventilation. It can be controlled with medication. Usually, appropriately lower the air humidity and pay attention to ventilation and light. Pests include scale insects, aphids, and others, which can be killed by spraying medication.

3. What Is the Difference Between Wen Zhu and Yun Zhu?

1. Height difference: Wen Zhu and Yun Zhu are actually the same plant, but they still differ. Yun Zhu is actually a dwarfed Wen Zhu, generally 5CM-20CM in height, while Wen Zhu can grow to 3 m-6 m.

2. Appearance difference: compared with Wen Zhu, Yun Zhu has very thick stems, especially thick leaves, and more compact foliage. Because the leaves are tight and thick, it looks very much like a pine, but its stems have a structure similar to bamboo nodes, so it also looks like bamboo.

3. Climbing difference: no matter how Yun Zhu grows, it will never climb. Wen Zhu is different: it will grow long vines, which can be cut off or left uncut. If you do not cut them, you need to set up a trellis for it and fix the long vines onto the trellis.

The above are the cultivation methods for Wen Zhu and the three differences between it and Yun Zhu. I hope they are useful to everyone.
