Culture methods of Brown Bamboo

Palm bamboo, also known as Guanyin bamboo, Jintou bamboo, palm bamboo, dwarf palm bamboo, etc., are evergreen foliage plants of the palm family. They often grow in shady, moist bushes beside hillsides and ditches, because they are shade-resistant, moisture-resistant and like scattered light. They can be placed in bright indoor places for a long time, which is of great ornamental value. Let's take a look at the cultivation methods of palm bamboo.

Culture Environment of Brown Bamboo

Brown bamboo likes a warm, humid and well-ventilated semi-shady environment, not resistant to stagnant water, extremely resistant to shade, afraid of the hot sun, slightly cold-resistant and can withstand about 0 ℃ of low temperature. When it is hot and bright in summer, it should be shaded properly. The suitable temperature is 10: 30 ℃, and when the air temperature is higher than 34 ℃, the leaves will often be scorched, the growth will stagnate, the overwintering temperature is not lower than 5 ℃, but it can withstand the low temperature of about 0 ℃, avoid the cold wind, frost and snow most, and can survive the winter safely in the general room. The plant shape is small, the growth is slow, and the requirement of water and fertilizer is not very strict. It requires loose and fertile acidic soil, not resistant to barren and saline-alkali, and higher soil moisture and air temperature.

Propagation methods of Brown Bamboo

1. Sowing and propagation: the loose permeable soil is used as the matrix, and the rotten leaf soil is generally mixed with river sand. The seeds can be soaked in warm soup before sowing, and then sowed when the seeds begin to germinate. Because of its irregular germination, it is appropriate to cover the soil a little deeper after sowing. Generally, it can germinate within 1-2 months after sowing, and the germination rate can reach about 80%. Transplanting can be carried out when the cotyledons of the seedlings are 8-10 cm long. It is worth noting that 3-5 plants should be planted in a clump when transplanting to facilitate survival and growth.

2. Ramet propagation: ramet propagation can be carried out in combination with turning the basin and changing soil in spring, the original plant cluster can be poured out from the old basin to remove the old mud, but take some old mud pile on the old root properly, cut off the brown bamboo root cluster with mulberry shears, and cut off the blackened and rotten roots with poor growth at the same time, the incision should be flat, at least 5 to 6 branches per clump, and 10 to 20 branches at most. Then plant it into the prepared pot, cover the drainage hole at the bottom of the basin with broken pieces to facilitate drainage, put in the culture soil first thick and then fine, put it to eight points full, while adding the culture soil, poke the soil and root tightly with small bamboo slices. Do not plant too deep, with the original root neck and culture soil flat, pour enough water, put the pot plant into half a shade for about half a month and then take the pot.

Culture methods of Brown Bamboo

1. Soil configuration: Brown bamboo bonsai can be mixed with rotten leaf soil, garden soil and river sand as substrate, and appropriate amount of base fertilizer can be added when planting. The sandy loam with a large amount of humus is the most suitable for potted soil. the cultivated soil can be mixed with 6 parts of garden soil and 4 parts of rotten leaf soil and planted in burning mud pot.

2. Light management: Brown bamboo is a plant in the south, which should be placed in a warm, moist, ventilated and shady place. At ordinary times, the key to maintenance is not to let the sun shine directly, otherwise it will cause the stems and leaves to be withered and yellow, and the potted plants should be placed under the scaffolding, under the big trees, with shaded balconies and corridors. The growing season should be shaded, especially in summer, or the leaves will turn yellow, the plant will grow slowly and low, and the shading degree will generally be about 50%. Brown bamboo growth requires a well-ventilated environment, such as poor ventilation is prone to shell insects.

3. Temperature management: Palm bamboo likes semi-shady, slightly humid and ventilated environment, has a certain cold tolerance, but does not tolerate the severe cold and frost in the north, so it can only be used as a potted plant in this area. It can survive the winter safely when it is moved indoors in winter and kept at a room temperature of not less than 5 ℃. The suitable temperature is 10-30 ℃, and when the air temperature is higher than 34 degrees Celsius, the leaves often have scorched edges, the growth is stagnant, the overwintering temperature is not lower than 5 ℃, the plant shape is small, and the growth is slow. Brown bamboo is afraid of cold in winter and is vulnerable to freezing damage at minus 3-4 ℃. It can be moved indoors to spend the winter, which can not only avoid frost damage, but also be used as hall and guest room decoration. Planting in the open field for the winter can protect the soil against the cold, cut off the old leaves in spring, and still sprout new leaves.

4. Timely watering: the temperature in summer is high, the soil is easy to dry, water should be watered sooner or later, and foliar water should be sprayed. Watering in spring and autumn should not be too frequent, as long as the basin soil is often kept moist (slightly dry), watering should be controlled in winter. Usually to keep the basin soil moist, but not stagnant water, brown bamboo is easy to rot roots, the most afraid of stagnant water. Water and spray foliar water in the morning and evening in summer.

5, rational fertilization: every 3-4 weeks in spring and autumn, 20% 30% rotten human feces and urine or cake fertilizer and water are applied to make the plant grow strong and the leaves green. During the growth period of spring and summer, thin fertilizer should be applied frequently, and the rotten cake should be better, and a small amount of ferrous sulfate can be added to the fertilizer to make its leaves green. During the vigorous growth period from May to September, liquid fertilizer was applied twice a month. In order to control the height, 400ppm paclobutrazol could be irrigated once in May, which could effectively control its overgrowth.

6. Pruning and turning the basin: the pruning of brown bamboo is very simple, mainly cutting off its withered and yellow leaves and diseased leaves. If the layer is too dense, it can also be thinned. The basin is turned every 2 years, and the new plants can be planted separately or rearranged. The time to turn the basin should be from March to April in spring. To replace the old soil above 1B2, cultivate loose humus soil.

7, pest control: Brown bamboo growth requires a well-ventilated environment, such as poor ventilation is prone to shell insects. If a small amount occurs, it should be manually scraped off in time, and controlled with 800 times omethoate, while paying attention to ventilation and timely pruning of withered branches and leaves. Brown bamboo has fewer diseases and insect pests, mainly shell insects, and often apply a small amount of ferrous sulfate solution to prevent leaf yellowing.

Matters needing attention in brown bamboo culture

1. During the growing period, brown bamboo should often spray water on the leaves of the plant, which is suitable for potted plants.

2. Although brown bamboo is shade-tolerant, it also needs proper light. If there is too little light, the leaves will turn yellow. If coupled with poor ventilation, plants will produce parasites and affect plant growth.

3. The amount of fertilization should be less and the number of times should be more. Mainly organic fertilizer, trace fertilizer as an auxiliary.

4. Brown bamboo needs a lot of water. When watering, remember to pour down from the growing point of brown bamboo, let the water flow down to the root, and maintain the humidity in the basin.

5. Brown bamboo is vulnerable to diseases and pests such as red spider, rust wall lice, leaf spot, shell insect and so on. If diseases and insect pests are found on leaves, they should be sprayed in time.
