How to grow potted fernleaf hedge bamboo? A detailed guide to the latest cultivation methods

Fernleaf hedge bamboo, also known as mi bamboo, jintou bamboo, Penglai bamboo, etc., is a variant of the hedge bamboo species Bambusa multiplex in the grass family Poaceae. Its plant form is short and small, with fine, dense, gracefully swaying green leaves, elegant in style, resembling a fern frond. It is often used for potted ornamental display, accenting small courtyards and rooms, and is also often used to make bonsai or as a low hedge material. Now let us take a look at how to grow potted fernleaf hedge bamboo!

Propagation methods for fernleaf hedge bamboo

1. Division: Division propagation of fernleaf hedge bamboo can be done in early spring when repotting. When dividing, take the overly dense clumps out of the pot, cut them apart at the rhizome with a knife, and pot them separately. Be careful not to damage the roots. When dividing, each shoot bud should have at least one old bamboo culm, and retain as many fibrous roots as possible to ensure survival. The newly divided plants should be planted in pots of moderate size, filled with fertile soil, watered carefully, kept moist, and maintained in a semi-shaded place; the shoot buds will then grow rapidly.

2. Sowing: Sowing propagation of fernleaf hedge bamboo is best done from April to May. Before sowing, soak the seeds in warm water for 1 to 2 days. After sowing, germination takes about 40 days. The seedlings grow very slowly, and it takes about half a year before they can be transplanted for growing on.

3. Cuttings: Cutting propagation of fernleaf hedge bamboo is done from May to June. Cut one-year-old branches into cuttings with 2 to 3 nodes, remove some leaves, insert them into a sand bed, keep moist, and they can root the same year.

How to grow potted fernleaf hedge bamboo?

1. Soil: Fernleaf hedge bamboo prefers acidic, slightly acidic, or neutral soil, with pH 4.5 to 7.0 being suitable, and it dislikes heavy, sticky, or alkaline soil. Northern soil is strongly alkaline, so 0.2% ferrous sulfate can be added. The soil should ideally be loose, fertile, well-drained sandy loam, and can be made from farmland soil mixed with red-yellow soil, humus soil, and fine sand.

2. Temperature: Fernleaf hedge bamboo is an evergreen clumping shrub that prefers a warm, humid, and semi-shaded environment. Its cold tolerance is somewhat poor, it cannot tolerate strong sunlight or waterlogging, and it prefers fertile, loose, well-drained loam. In winter, the temperature should not be lower than 0 degrees.

3. Light: Fernleaf hedge bamboo likes light and is slightly shade-tolerant, and it prefers a warm, humid climate. It likes moisture and warmth, and also likes semi-ventilated and semi-shaded conditions. In winter it should be moved indoors to a sunny place. Fernleaf hedge bamboo likes sunny, high, and airy sites, and there is a saying that “it flourishes in the sun and should be planted on a high platform.” In spring, summer, and autumn, it only needs to be placed in a ventilated spot by a window, and in winter it can be placed in a sunny spot, and it will grow well.

4. Water: Fernleaf hedge bamboo likes moisture and fears waterlogging. After potting, the first watering should be thorough, and afterward the potting soil should be kept moist. Do not water too much, otherwise the rhizomes and roots are prone to rot. From potting to the stage of establishment, the leaves should also be sprayed with water frequently. If the potting soil lacks water, the bamboo leaves will curl; at this point, water promptly and the bamboo leaves will spread out again. In summer, water once every 1 to 2 days on average; in winter, water less, but still keep the potting soil moist to prevent “dry freezing.”

5. Fertilizer: Fernleaf hedge bamboo is mainly fertilized with organic fertilizer; decomposed livestock manure, garbage compost, and river mud are all suitable. Organic fertilizer is mainly used as a base fertilizer, mixed into the potting soil, generally at 10% to 15% of the volume of the potting soil. During the growing season, apply 1 to 2 times a month of dilute nitrogen fertilizer.

What to do if fernleaf hedge bamboo leaves turn yellow?

1. Sunlight exposure: Fernleaf hedge bamboo likes a semi-shaded environment. If the sunlight is too strong, it will speed up water evaporation from the leaves and cause the leaves to wither and yellow. But if fernleaf hedge bamboo is placed in a shady environment with no light for a long time, it will lack chlorophyll, causing the leaves to yellow and even fall off. A semi-shaded spot by a window has sufficient light, no strong direct sunlight, and good ventilation, so fernleaf hedge bamboo should be moved to a semi-shaded place. Generally, in spring, autumn, and summer, place fernleaf hedge bamboo in a ventilated spot by a window, and in winter place it in a sunny spot.

2. Lack of nutrients: If fernleaf hedge bamboo lacks nutrients during growth, especially if fertilizer is not applied, the young leaves will also appear pale yellow. At this time, fertilizer can be applied appropriately and water given. A lack of phosphate fertilizer in the soil or excessive fertilization can both cause fernleaf hedge bamboo leaves to wither and yellow; if phosphate fertilizer is lacking, simply supplement it.

3. Long-term fertilizer depletion: If nitrogen fertilizer has not been applied for a long time or the pot and soil have not been changed, the soil lacks nitrogen and other nutrient elements, causing the branches and leaves to become weak and the leaves to be thin and yellow. The pot should be changed promptly, new loose and fertile growing medium should be used, and dilute decomposed liquid fertilizer or compound flower fertilizer should gradually be applied in increasing amounts. Overfertilization. If too much fertilizer is applied, new leaves will become thick and fleshy, and often uneven, while old leaves will dry at the tips, scorch yellow, and fall off. Fertilization should be stopped immediately, watering should be increased so the fertilizer flows out from the drainage holes at the bottom of the pot, or the pot should be changed immediately, the root ball rinsed with water, and then replanted in the pot.

4. Water aspects: When fernleaf hedge bamboo lacks water, the leaf edges or leaf tips will dry and yellow, and may even fall off. At this time, water fernleaf hedge bamboo promptly, but do not water too much; one thorough watering to keep the potting soil moist is enough. Too much water will cause root rot, and the leaves will turn watery yellow; after loosening the soil, dry out the excess moisture. If the leaves appear watery yellow, especially if the young leaves are rather small and no longer grow upward, it indicates that there is too much water in the soil; at this time, loosen the soil and dry out the moisture. If the leaf edges or leaf tips dry and yellow, or even fall off, it indicates that the soil lacks water, and the soil should be watered promptly.

5. Pests and diseases: Leaf spot disease caused by infection by fungi and other pathogens easily causes local necrosis of the leaves, with yellow spots or patches appearing, and in severe cases the whole leaf withers, yellows, and falls off. After infection by mosaic virus, yellow-green mottled patches appear on the leaves. When damaged by scale insects, red spiders, and the like, the leaves also become locally yellow and withered, and may even wither, yellow, and fall off entirely. In all cases, pesticide should be sprayed promptly for control.
