How to grow potted bamboo? Cultivation methods and precautions

Bamboo has been cultivated in China for a very long time. Bamboo has a rather slender shape and straight culms, so many people also use bamboo to describe a person's character. Nowadays many people like to grow bamboo as a potted plant at home, but when growing bamboo at home you should not be careless and need to care for it attentively.

How to grow potted bamboo

1. Soil. Bamboo likes acidic and neutral soil. A pot is a special small environment; the soil capacity in a pot is limited, and its buffering capacity for water, fertilizer and so on is relatively poor, so the potting soil should be a substrate soil that is relatively loose, well drained and well aerated, while also having strong water retention and fertilizer-holding capacity and being relatively light in weight. This not only favors the growth and development of the bamboo root system and the activity of rhizosphere fungi, and prevents root rot caused by waterlogging, but also ensures sufficient water and fertilizer for the bamboo's growth and development needs.

2. Light. It needs light, but it must not be too intense. In summer it must be shaded. In winter, place it in a sunny and wind-sheltered spot.

Potted bamboo cultivation methods and precautions

1. Cultivation methods

1. Water management. Potted bamboo likes shallow planting in the open ground and should not be buried deep in thick soil. The potting soil should be on the dry side, and muddy soil should be avoided. In the heat of summer do not let direct sunlight hit it; water once every morning and also spray the branches and leaves once in the evening, so as to keep the potted bamboo verdant and green. When the temperature drops to about 10 degrees C, it should be moved indoors for cultivation to avoid withered shoot tips and leaf loss. For overwintering, keeping it at 10 degrees C is suitable. Water less in winter, but keep the potting soil moist to prevent "dry plants."

2. Control fertilizer use. The fertilizer for potted bamboo is mainly the organic fertilizer mixed into the potting soil when potting. Potted bamboo is grown mainly for ornament, and it is required to be short and small, so it should be kept to between 50-60 cm. Because the potting soil is shallow and thin, the amount of fertilizer applied must be controlled. If fertilizer is applied blindly, the potted bamboo will grow tall and thick, losing its dainty and unique charm.

2. Precautions:

In winter, it needs to be kept in a warm place, or covered with plastic film to keep it warm. In summer, when evaporation is especially high, it is necessary to frequently spray a little water on the leaves.

What to do if bamboo leaves turn yellow

1. Fertilizing: When transplanting, pay attention to mixing base fertilizer into the soil. After the bamboo has recovered from transplanting, pay attention to topdressing. Following the principle of "light fertilizer applied frequently," apply compound fertilizer in spring and summer to maintain nutrient supply. If it is fertilizer damage, immediately drench the pot to dilute the fertilizer concentration or wash the fertilizer away; if necessary, dig the bamboo out and wash the roots.

2. Watering: When transplanting, the soil moisture should not be too much, but pay attention to spraying water on the leaves. When bamboo lacks water, the leaves will curl slightly; at this time it should be watered promptly, and after the water is replenished the leaves will quickly unfold. In hot summer weather, pay attention to replenishing water more; in winter water less to prevent freezing inside the pot.

3. Ventilation: Bamboo planted in a courtyard should be placed by a wall that is ventilated and able to receive sunlight; if it is potted, it should be placed by a window so that it can receive sunlight and also be ventilated.

Common bamboo diseases and their control

1. Bamboo shoot rot. Control method: Do not choose vegetable, pine or fir land as the nursery site, and the base fertilizer must be fully decomposed. Use 2-year-old robust bamboo culms for propagation. When bamboo shoots with rotted leaf tips and shoot tips are found, they must immediately be cut off from the base. After emergence (or at the beginning of the disease), spray 50-times Bordeaux mixture or potassium permanganate, once every 10 days, until the bamboo seedlings grow robustly.

2. Moso bamboo shoot blight and top dieback. Control method: Remove the pathogen: in conjunction with bamboo forest felling and tip hooking, cut off the bamboo plants or bamboo tips already infected with top dieback, and promptly burn the diseased bamboo and branches. Do not use diseased bamboo or dead branches to make fences and the like. In the peak disease period of July to August, investigation should be strengthened. If new bamboo branches and leaves are found to be yellow and withered, and brown lesions appear on the nodes of the bamboo culm, the bamboo tip should promptly be hooked off 1-2 nodes below the affected site, so as to prevent the disease from continuing to spread and causing the whole plant to die. Use 50% carbendazim wettable powder or 70% thiophanate-methyl wettable powder, at a 1:1,000 dilution, or 1% Bordeaux mixture, spraying once every 15 days starting from when the new bamboo unfolds its leaves.

When growing bamboo, be sure to pay attention to the soil ratio and then do a good job of controlling light. In the later stages of cultivation, water management also needs to be strengthened, and timely fertilizing is also very important. If you find that the bamboo leaves have turned yellow, do not panic first; find the cause and then solve the problem at its root.
