How to grow spider orchid?

(1) Temperature: It likes warmth, and the most suitable temperature for growth is 21-27℃. It is not cold-resistant, and growth stops at temperatures below 15℃. The leaves turn yellow and wilt at temperatures below 1℃, and the aboveground parts wither at 5℃. The wintering temperature should not be lower than 10℃. If the aboveground parts wither, it can enter a dormant period in the form of underground bulbs, and new leaves can still sprout and grow when the temperature rises in the following spring. It is also possible to store pseudobulbs in sawdust or sand from December to March of the following year, and maintain a temperature of about 8℃, and then plant them in the open field in spring.

(2) Light: It prefers semi-shady environment and has strong shade tolerance. However, if it is placed in the shade for a long time, the leaves will become thinner and darker, resulting in an ugly plant shape. Avoid strong sunlight exposure, otherwise the leaves will turn yellow and burnt. Shade should be provided from May to September, or place it in a place with sufficient scattered light. It should be given sufficient sunlight at other times.

(3) Watering: It prefers a moist soil environment and cannot tolerate drought. During the growth period, especially in the hot summer, it should be fully watered to keep the soil moist and prevent it from being too dry. It also avoids waterlogging. After the rain in the rainy season, the accumulated water in the pot should be poured out in time. In winter, it is necessary to water sparingly and keep the soil relatively dry. When the temperature is low and the humidity is high, the pseudobulb is prone to rot.

(4) Fertilization: It likes fertilizer. In spring, after the plant grows, apply nitrogen-based fertilizer once every half month to promote plant growth. After entering the bud formation stage, apply phosphorus and potassium fertilizers to make the flowers large. Fertilization should be stopped during flowering. After flowering, apply nitrogen and potassium-based fertilizers to facilitate the growth of stems and leaves and the hypertrophy of pseudobulbs. If the growth environment is relatively shady, the supply of nitrogen fertilizer should be reduced, and phosphorus and potassium fertilizers should be increased, which can ensure that the plant grows strong and does not grow too tall. Stop fertilizing in winter.'

(5) Pruning: After the flowers fade, cut off the flower stalks in time to prevent fruiting and consuming nutrients, which will affect the growth of the plant. If the indoor space is small, you can cut off the leaves of the above-ground part before winter comes, place the potted plant in a dry and shady place, and keep the room temperature at 5-10℃. After repotting in the spring of the following year, plant the Wuhe in the sun.

(6) Repotting: Repot once every 2 to 3 years in April. It prefers fertile, moist, organic-rich and well-drained clay soil. The substrate can be made of leaf mold, garden soil, peat soil, plain sand and other materials. It should not be planted too deep, and the top of the pseudobulb should be level with the potting soil. However, the bulblets can be planted a little deeper.

(7) Pest and disease control: Brown spot disease is prone to occur in high temperature, high humidity or low temperature seasons, so attention should be paid to prevention and control. When brown spot disease damages, small round brown spots appear on the leaves, which gradually expand, with the edges of the spots turning black and brown, and the center gray and black, until the spots are connected and the leaves die. Other pest and disease damages include leaf scorch and red spider mites.

Taeniophyllum glandulosum Bl., also known as the ribbon-leaf orchid, is a plant of the genus Taeniophyllum in the family Orchidaceae. The plant is very small, without green leaves, and has well-developed roots. The stem is almost absent, covered with many brown scales. The roots are numerous, clustered, slightly flat and curved. There are 1-4 racemes, erect, and the capsule is oval-cylindrical, 4 mm long and about 2 mm thick. The flowering period is from April to July, and the fruiting period is from May to August. It is distributed in Fujian, Taiwan, Hunan, Guangdong, Hainan, Sichuan, Yunnan and other places in my country. It often grows on tree trunks in mountain forests at an altitude of 480-800 meters.

The efficacy of water banana

The efficacy of water banana, also known as spider orchid, its flower looks like a spider. Many people often confuse water banana with Crinum orchid. Next, we will introduce the difference between water banana and Crinum orchid and the efficacy of water banana, let's take a look!

The effect of water ghost banana 1. The difference between water ghost banana and Crinum orchid

1. The difference between water banana and Crinum serrata is the leaves are different

The water banana has multiple leaves, concentrated at the base, growing on the stem. The leaves are sword-shaped, about 45 to 75 cm long and 2.5 to 6 cm wide. They grow opposite each other, dark green in color, and have veins.

The leaves of Crinum japonicum are relatively large, with 20-30 leaves, 0.9-1.2 meters long and 7-12 centimeters wide. The edges of the leaves are wavy and look soft. The light green leaves are broad and thick, growing on the upper part of the plant.

The leaves of the water ghost banana are stiffer than those of the crinum, and the midrib is more concave. In terms of number, the leaves of the crinum are more numerous, longer and wider. The leaves of the water ghost banana are opposite, and they are called things.

The leaves of the Crinum orchid appear to be growing in circles.

2. The difference between water banana and Crinum serrata is the difference in flowers

The style of the water banana is darker green, and the surface seems to be covered with a layer of frost, and it is not as green and smooth as the style of the Crinum japonica.

The petals of Crinum japonicum are purple in the middle and pink on both sides. When in full bloom, they stretch out to the surroundings and even bend backwards. The petals of water banana are slender and wide apart. When in full bloom, the front ends of the petals turn slightly downward. The difference between water banana and Crinum japonicum is that the flowers of water banana have umbrella-shaped corollas, which is obviously different.

In addition to the difference in flower shape, the number of flowers is also different. Crinum striata usually has 10-24 flowers on each inflorescence, while the inflorescence of Glechoma longituba usually has 3-8 flowers growing on the top of the flower stem. If you observe carefully, it is not difficult to distinguish the two.

The efficacy and function of water banana 2 The growth habits of water banana

The water banana is native to tropical America and the West Indies. It likes plenty of sunlight, warm and humid climate, and is not cold-resistant. It is not very demanding on soil, prefers fertile soil, can be potted with leaf mold, or planted in clay soil. The winter temperature of potted water banana is above 15 degrees Celsius, and water and fertilizer should be sufficient during the growing period. Water banana planted in the open field needs to be dug in autumn and stored indoors. With a little maintenance, water banana will grow and bloom year after year.

How to propagate water banana

1. Bulb division: Bulb division of water banana can be carried out in April and May every year in combination with repotting. When repotting, dig out the bulbs and plant them. When planting, be careful not to plant too deep, just keep the neck of the bulb level with the ground. The bulbs can be buried a little deeper. In North China, potted water banana is planted in March, and outdoor planting is best done in early May, and must be done after frost.

2. Division: As the water banana grows, some small buds usually grow on the mother plant. These small buds are used for division. Generally, in February or March in spring, the mother plant of the water banana is removed from the pot and soil, and then the small buds beside the mother plant are cut off. The cut small buds are the daughter plants, which can be directly potted. Usually, the division is combined with repotting once every 3 to 4 years.

How to cultivate water banana

1. Soil: The water banana is not very demanding on soil. It can be potted in leaf mold or clay soil. Potted water banana can be planted in early spring. It is usually planted in a mixture of peat soil, fertile garden soil and river sand. The planting depth should be level with the top of the pseudobulb and the potting soil. For ground planting, choose deep, fertile, well-drained clay soil. It is best to plant in early May.

2. Watering: The water banana likes a moist soil environment and is not drought-resistant. During the growth period, especially in the high temperature in summer, it should be fully supplied with water to keep the pot soil moist and prevent it from being too dry. Avoid waterlogging. After the rain in the rainy season, the accumulated water in the pot should be poured out in time. In winter, watering should be restrained to keep the pot soil relatively dry. When the temperature is low and the humidity is high, it is easy for ants to suffocate and cause the pseudobulb to rot.

3. Light: The water banana prefers a semi-shady environment and has a strong tolerance to shade. When the light is too strong in summer, it is advisable to shade it appropriately or move the flower pot to a semi-shaded place. If the water banana is placed in a shaded place for a long time, the leaves will become thinner and the leaf color will become darker, resulting in an ugly plant shape. Avoid strong light exposure, otherwise the leaves will turn yellow and burnt. Shade it from May to September, or place it in a place with sufficient scattered light. Give it sufficient sunlight at other times.

4. Temperature: Water banana likes warmth and cannot tolerate cold. The suitable temperature for its growth is 21-27 degrees Celsius. When the temperature is below 15 degrees Celsius, the growth of water banana stops. When the temperature is below 10 degrees Celsius, the leaves turn yellow and wilt. When the temperature is 5 degrees Celsius, the aboveground part dies. The overwintering temperature of potted water banana is above 15 degrees Celsius. If the aboveground part dies, it can enter a dormant period in the form of an underground bulb, and new leaves can still sprout and grow when the temperature rises in the next spring.

5. Fertilization: Fertilize once every half month during the growth period of the water banana. After entering the bud formation stage, apply more phosphorus and potassium fertilizers to make the flowers bloom larger. Fertilization should be stopped during flowering. After flowering, apply nitrogen and potassium fertilizers to facilitate the growth of stems and leaves and the hypertrophy of pseudobulbs. If the growth environment is relatively shady, the supply of nitrogen fertilizer should be reduced, and phosphorus and potassium fertilizers should be increased to ensure that the plants grow strong and not too long. Stop fertilizing in winter.

6. Diseases and pests: Water banana is prone to brown spot disease in high temperature, high humidity or low temperature seasons, so attention should be paid to prevention and control. When brown spot disease damages, small round brown spots appear on the leaves, which gradually expand, with dark brown edges and gray-black centers until the spots are connected and the leaves die. If a small amount is found, pick the old diseased leaves and destroy them. If the disease is serious, spray 75% mancozeb wettable powder at a concentration of 500 times.

7. Pruning: After the flowers of the water banana fade, cut off the flower stalks in time to prevent fruiting and consuming nutrients, which will affect the growth of the plant. If the indoor space is small, you can cut off the leaves on the ground before winter comes, place the potted plant in a dry and shady place, and keep the room temperature at 5-10 degrees Celsius until the next spring when you repot it and plant it in the sun.

8. Repotting: The water banana potted plant should be repotted once every 2 to 3 years in April. It prefers fertile, moist, organic-rich and well-drained clay soil. The substrate can be prepared with leaf mold, garden soil, peat soil, plain sand and other materials. It should not be planted too deep, with the top of the pseudobulb flush with the potting soil, but the bulbs can be planted a little deeper.
