The pot soil should be mixed with rotten leaf soil with good drainage and river sand with 1 blade and 3 river sand, and a small amount of bone powder should be added as base fertilizer at the bottom of the basin, and a dilute liquid fertilizer with the proportion of 40% nitrogen, 30% phosphorus and 30% potassium should be applied every half month during the peak growth period, so as to maintain the luster of the leaves. Potted plants should not be too deep, just plant all the roots into the soil, otherwise it will affect the growth of new buds. At the end of autumn, pay attention to spraying potassium dihydrogen phosphate (0.2% to 0.3%) to facilitate plant growth and improve cold resistance in winter.

two。 Keep the potted soil moist often, but be careful not to get too wet so as not to rot the roots. Higher requirements for air humidity, it is best to maintain about 75%, such as the air is too dry, the new leaves will appear the phenomenon of leaf curl does not stretch, so the growing period should pay attention to often spray water to the leaf surface and around to improve air humidity, but should also pay attention to maintain good ventilation.

3. Like warmth, the suitable temperature for growth is 18 ℃ to 25 ℃, not resistant to cold, overwintering temperature should not be lower than 16 ℃, if the long-term lower than 13 ℃, will suffer chilling injury. If the temperature is low in winter, the basin soil should be kept dry, otherwise it is easy to cause scorched leaves or root rot, and the night temperature should not be lower than 16 ℃.

4. Avoid strong light exposure, the light should not be too strong, otherwise there will be leaf yellowing, curling up and other phenomena, but long-term lack of light will not make photosynthesis can not be carried out normally, affecting normal growth, 70% shade in summer and 30% shade in winter.

5. Change the basin with the culture soil every summer, remove the rhizosphere soil, cut off some of the old roots, and add new soil for planting. If the pot plant has grown larger, it can be planted in a larger pot or ramet, watered thoroughly after planting, and cultivated in a semi-shady place.

6. It is easy to suffer from leaf blight, leaf spot, whitefly, red spider and shell insect, so we should pay attention to observation and timely diagnosis and treatment after discovery.

7. The method of plant division can be used for propagation, which should be carried out when the temperature is more than 18 ℃ in spring or autumn. The plant should be removed from the basin, part of the persistent soil should be removed, and the rhizome growing laterally should be divided into several clumps, each clump should have 3 to 4 small plants, and then planted separately.

2. Watering: velvet taro is very sensitive to water. During the growing season, the basin should be fully watered to keep the basin soil moist. But do not water too much, the soil is too wet, will cause root rot, or even death. In addition, if the air humidity is small, the leaves of velvet taro will immediately become curly, so we should pay attention to maintain appropriate humidity during cultivation, especially at high temperature to spray water to the leaves to increase air humidity.

3. Lighting: velvet taro likes semi-overcast environment and avoids strong light exposure. Therefore, when raising velvet taro, the light should not be too strong, otherwise the leaves will turn yellow and curl up, but it is not good to put velvet taro in a completely shaded environment for a long time, which will affect the photosynthesis of velvet taro, thus affecting its normal growth.

4. Fertilization: in the vigorous growth period of velvet taro, liquid fertilizer can be applied every 1-2 weeks, and phosphate fertilizer can be applied 1-2 times properly to maintain the luster of leaves. Plants with low temperature in winter grow slowly or enter a dormant period, so fertilizing should be stopped and watering should be controlled.

5. Diseases and insect pests: velvet taro is easy to suffer from leaf blight, leaf spot, whitefly, red spider and shell insect, so we should pay attention to observation when breeding and treat the disease in time after discovery.

6. Change the basin: when raising velvet taro in pots, the pots should be changed every May. It is mainly to cut off part of the old roots and add new soil for planting. If the plant is larger, it can be planted in a larger pot or ramet, watered thoroughly after planting and cultivated in a semi-shady place. Pot soil should be mixed with rotten leaf soil with good drainage and river sand, and a small amount of bone powder should be added to the bottom of the basin as base fertilizer. Do not use sticky soil pot planting, pot depth to not expose the root is appropriate.

7. Reproduction: velvet taro is mainly propagated by individual plants, and the best time is after soil thawing in early spring (February and March). Ramets should not be too small, so as not to affect the growth of new plants. After potted, the moisture of the new plant should be controlled and maintained in a semi-shady place, and the new root should be fully irrigated after the new root is sent out.

3. Disease: velvet bamboo taro is in the environment of high temperature, humidity and poor ventilation for a long time, which will make the plant grow weaker and prone to leaf blight. Generally, infection occurs from leaf edge and leaf tip, and the disease spot is irregular from small to large, reddish brown to grayish brown, and the disease is serious in the lower leaves of the plant. The main diseases and insect pests are leaf spot disease and leaf blight, which are sprayed with lime Bordeaux solution. The insect pest is harmful to whitefly and is sprayed with 1000 times of imidophos EC.

The above is the introduction of velvet taro culture methods and how to yellowed velvet taro leaves. Velvet taro potted plants are suitable for family, hotel and public decoration, and are often used for flower arrangement.
