How to raise the latest potted rich bamboo?

Rich bamboo is also known as longevity bamboo, open bamboo, rich tower, etc., which belongs to the tequila family, is a perennial small evergreen tree foliage plant, originated in the Gali Islands and tropical Africa and Asia, and was introduced into China in large quantities since the late 1980s. It is generally used for family vase or potted conservation, and the ornamental value is very high. Let's take a look at how to raise potted rich bamboos.

Growth habits of Phyllostachys pubescens

Fugui bamboo is suitable for growing in sandy soil or semi-muddy sand and alluvial clay with good drainage, such as high temperature, waterlogging resistance, strong fertility resistance, cold resistance and semi-shade environment. Like the warm environment, the temperature is suitable for 18-24 ℃, can grow all the year round, below 13 ℃, the plant dormancy and stop growing. When the temperature is too low, because the root system does not absorb enough water, the leaf tip and leaf edge will appear yellow-brown patches, and the lowest overwintering temperature should be more than 10 ℃. Light requirements are not strict, suitable for growth under bright scattered light, excessive light, exposure will cause leaves yellowing, chlorosis, slow growth and other phenomena.

Propagation methods of Phyllostachys pubescens

1, soil culture propagation: rich bamboo soil culture propagation is to cut at least 10 cm stout stem, with leaves, the incision oblique cut, conducive to gas roots, inserted into the sand bed, and maintain the temperature at about 25 degrees, a month can take root and survive.

2. Hydroponic propagation: the hydroponic propagation of Fugui bamboo is to cut the stout stem of 10 cm, with leaves, cut the oblique mouth, and then insert it into the water. Pay attention to 1/3 of the whole plant immersed in the water, and due to the scarcity of nutrients in the water, nutrient solution needs to be added to improve the survival rate.

How to raise potted rich bamboo?

1. Soil: the ability of rich bamboo to adapt to the environment is very good, and it is suitable to grow in clay and sandy soil, and it is best to grow in sandy soil with loose, fertile and good drainage humus. Special plant nutrient soil, rotten leaf soil and river sand can also be used to grow together. In the process of breeding, the pot is changed every two years, which is conducive to the healthy growth of rich bamboo.

2. Watering: Fugui bamboo sprays water once a day in summer to wash the foliar dust to improve humidity, usually like to be moist, the growing season should keep the soil moist, and often spray or spray water to the leaves to increase the temperature of the air, but the water will grow, affect the beauty, generally keep the soil moist.

3. Fertilization: the requirements of rich bamboo on the environment are not so strict, especially on fertilization, but still have a certain amount of topdressing in the process of growth. Use chemical fertilizers and organic fertilizers for liquid fertilization, use a small amount of chemical fertilizers frequently, and need to water some water after fertilizing.

4. Temperature: Fugui bamboo is relatively cold-resistant, and the suitable growth temperature is 20-28 ℃, which can withstand 2-3 ℃ low temperature. But to prevent frost in winter, too low temperature will cause frostbite, resulting in wilting. Summer and autumn is a hot and humid season, which is very beneficial to the growth of rich bamboo, and it is the best time for its growth.

5, lighting: rich bamboo likes to grow in a warm environment, but avoid high temperature, can not grow in the summer sun, potted culture can be placed under the window and balcony, avoid direct sunlight, can give a certain amount of light, this is conducive to its healthy growth, otherwise the leaves will be dim or golden, there is no good ornamental value.

6. Diseases and insect pests: leaf spot, root rot, stem rot and other viruses will appear in the growth process of Fugui bamboo, which can be sprayed on the leaves with 100 times Bordeaux solution. Pests include thrips and shell insects, which can be sprayed with 1000 omethoate and EC, which can help kill insects effectively.

What if the rich bamboo leaves turn yellow?

1. Too much watering: the newly grown leaves are relatively dark yellow and without luster, but the old leaves do not have any obvious changes, the branches are relatively small, and the new shoots are relatively yellow and green, and the new shoots are shrunk, all of which are caused by too much watering. It is necessary to put it in a ventilated and hidden environment to dry, and then sort out the basin soil.

2. Lack of water: when the rich bamboo lacks water, the leaves will turn yellow. The tip and edge of the leaf will dry and wither, and the old leaves will fall off from the bottom up, but the newly grown young leaves are relatively normal, so it is necessary to pour water through and give them enough water.

3. Too strong light: too strong light will cause rich bamboo leaves to turn yellow, leaf tips and leaf edges will wither, and yellow spots will appear on the leaves, which need to be cultured in a more hidden place. Pot culture can be placed under the window and on the balcony to avoid direct sunlight and give some light, which is conducive to its healthy growth.

4. Too little light: if the bamboo is cultured in a relatively hidden environment for a long time, the leaves can not absorb enough light, the leaves can not form chlorophyll, and the leaves will turn yellowing. Need to put more sunny places for culture, but avoid the occurrence of direct light.

5. Excessive fertilization: when cultivating rich bamboo, too much or too much fertilization will cause the leaves to turn yellow. generally, the leaves will appear dry brown at the top of the new leaves. although the leaves are embarrassed and thick, they do not have any luster, and the leaves do not stretch completely. The old leaves will fall off naturally after yellowing, so stop fertilizing and watering more, so as to wash some nutrients.

6. Insufficient fertilization: in the case of insufficient fertilization, the leaf color of rich bamboo will be relatively light, usually light green or yellow. At this time, you can check the basin soil, you can change the soil in the case of dry soil, apply more thin fertilizer or alum in it, mainly with nitrogen fertilizer as the main fertilizer.
