Guanyin bamboo

1. Cultivation methods of Guanyin bamboo

1. Bonsai Guanyin bamboo should be moved to an outdoor cool place in summer, and pay attention to watering more to keep the potted soil moist and moist, as well as sprinkling water to foliar fountains and the ground to maintain moist and moist air and the ability to make Guanyin bamboo branches and leaves green. The dry and hot wind in summer will scorch the leaves of Guanyin bamboo. It must be appropriate to lower the temperature to avoid stagnant heat. Cold winter needs to be kept indoors, control nutrients, and rest on fertilizer. The indoor temperature should be maintained above 10 ℃.

2. During the growth time, liquid fertilizer should be applied every 20 days or so. Liquid fertilizer can be used with bean cake water with low maturity density, or compound liquid fertilizer. The cold winter should rest and fertilize.

3. Guanyin bamboo does not need to change pots year after year. The basin is usually changed every 2 years. The cultivation soil of bonsai is 1 part of rotten leaf soil and 0 part of garden soil. It is made of 5 parts, and a small amount of river sand and rice chaff ash.

4. Ramet or ovule can be used in Guanyin bamboo. Ramet can be carried out in early spring when joining and changing pots. When ramets, the overgrown clumps of plants are poured out of the basin, cut with a knife from the rhizome, and put on the basin separately. Be careful not to hurt the roots. After dividing the plant, it should be placed in a cool place, watering thoroughly for the first time, and then just keep it moist and moist, not too much watering. The information of ovule should be carried out from April to May, and warm soaking should be used for 1-2 days before sowing. It can sprout about 40 days after sowing. The seedlings grew very slowly and were able to transplant and cultivate after about half a year.

Second, the leaves of Phyllostachys pubescens are yellowing in water culture.

The main results are as follows: 1. Water yellow: the young leaves are dark yellow and dull, the old leaves have no obvious change, the branches are small and yellow-green, and the new shoots are not long, indicating that they are overwatered. Remove the flowers from the pot and place them in a ventilated, cool, self-drying soil mass and then put them back into the basin.

2. Dry yellow: the yellow with lack of water is different from the yellow with more water, the yellow with lack of water is withered and dry at the tip or edge of the leaf, and the old leaf is withered and yellow from the bottom up, but the growth of the new leaf is relatively normal. Pay attention to watering enough and thoroughly.

3. Burning yellow: strong sunlight shines directly on some shade-loving flowers (such as hanging orchids, hairpins, etc.), which can easily cause withered leaf tips and edges, and macula in the sunrise part of the leaves. Just move to the shade.

4. Lack of light and yellow: put in a shady environment for a long time, the leaves can not get enough sunlight, can not form chlorophyll, the whole leaves turn yellow and then fall off, supplementary light can avoid the disease.

5. Fat yellow: flowers yellowing caused by too much fertilization or too much concentration, showing dry brown at the tip of new leaves, general leaf thickening and no luster, and concave and convex not stretching, old leaves scorched yellow shedding. Fertilizer should be stopped immediately and some fertilizers should be washed with a large amount of washing.

6. lack of fat yellow: the color of the tender leaves becomes lighter, yellow or light green, while the old leaves are more normal or gradually change from green to yellow. Check the basin soil, if there is a dry phenomenon should change the soil, usually apply thin fertilizer frequently and timely sprinkle some alum (Guanyin bamboo is Guanyin bamboo should be nitrogen-based fertilizer).

7. Root-cutting yellow: don't cut off the roots in winter, so they can't absorb water, and the leaves will naturally turn yellow.

The plant type of Guanyin bamboo is short, and if it is designed properly, it can be raised as a small potted plant. However, Guanyin bamboo will continue to grow taller during the growing season, and friends who raise it indoors can cut off the high part as needed.

What about the yellowing leaves of Phyllostachys pubescens? the culture method of Phyllostachys pubescens

I. Culture methods of Phyllostachys pubescens

1. Choose the suitable cultivation season. The cultivation should be carried out in March, when the mother bamboo has a high germination rate and is the easiest to survive.

two。 Choose the ideal mother bamboo. The mother bamboo should grow healthily, free from diseases and insect pests, the stem bud eye is enlarged, the fibrous root is well developed, and the bamboo age is better in 2012.

3. Planted in time. If long-distance transportation is really needed, it should be watered and moisturized in a cool shelter and properly handled during packaging to prevent damage to the root eye and vibration of the lodging soil.

4. Apply sufficient base fertilizer before planting to ensure adequate nutrition. Choose soft and fine soil, first fill in the bottom of the hole, then apply rotten stable fertilizer, mix well with the topsoil, put the mother bamboo down, cover the soil layer by layer, and cover the soil slightly 2 cm to 3 cm deeper than the original soil of the mother bamboo.

5. Pour enough water to fix the root. Watering in time after planting, be sure to water thoroughly for the first time, and then reduce the amount of water appropriately, as long as it is wet and dry.

How to raise Phyllostachys pubescens? what if the leaves turn yellow?

Phoenix tail bamboo is actually one of our common potted plants, because it has the role of absorbing formaldehyde and purifying the air, so it has been favored by people. The Phoenix tail bamboo, which originated in the southern part of China, likes a warm, humid or semi-shady environment, its cold resistance is relatively poor, and it is not resistant to strong light exposure to it. It is also cultivated in the Yangtze River and the south of China or in Japan and India. So how do we need to raise it? What should we do if its leaves turn yellow?

[growth habits] first of all, we need to know that Phyllostachys pubescens likes a warm, humid and semi-shady environment, of course, it belongs to a plant with poor cold tolerance, and it can not be resistant to strong light exposure. Waterlogging is the most suitable for growing in fertile, loose and well-drained loam, and its lowest temperature can not be lower than 0 degrees in winter.

[culture method] temperature: Phyllostachys pubescens is an evergreen tufted shrub plant, so it also belongs to a humid and semi-shady environment, and its cold tolerance is relatively poor and can not withstand strong light exposure to it. I'm afraid that stagnant water likes to live in a loose and fertile environment with good drainage, and the lowest temperature in winter can not be lower than 0 degrees. Lighting: like light can only slightly withstand shade, it also likes the warm and humid climate. Wet and warm environment is its favorite, it also likes semi-ventilated and semi-overcast environment, in winter it should be moved into the indoor and sunny place for breeding, placed in the sunny place can make it grow more healthily. Soil: Phyllostachys pubescens likes acidic or slightly acidic loam, if it is planted with ordinary basin soil, its survival rate will be very low, and with peat mixed with perlite as the matrix, its survival rate will be relatively high. and to maintain the grace of the posture, the pressure ball of the soil is not high, generally only need to use loose sandy soil. Moisture: Phyllostachys pubescens likes to be wet but afraid of stagnant water, it needs to be watered thoroughly the first time it is installed in the basin, and it only needs to keep the soil moist in the future, and it can't be watered too much, otherwise it will cause its roots to rot.

The cause of yellowing may be due to the strong light on it, resulting in the loss of water in the leaves and yellowing. At this time, we only need to put it in a cool place. 2. In the process of its growth, if there is a lack of nutrition, especially the lack of fertilizer, it will also lead to the yellowing of its tender leaves, as long as we need to fertilize and water it properly. 3. Too much fertilization may lead to the yellowing of the leaves, especially the new leaves will appear dull. At this time, we should pay attention to dilute the fertilizer in the soil, of course, we can also add water to the soil to dilute.
