Below, Xiaobian will introduce you to the breeding method of Vanda orchid and the flower language of Vanda orchid for your reference.

Vandai orchid was originally a Sanskrit word for Indian, meaning orchid hanging on tree. She is a very special orchid. Without soil, without any plant material, it can grow very vigorously. It is an aerial orchid that absorbs oxygen from the air only by its aerial roots. In the wild state is attached to the trunk or stone growth, which seems to go beyond our understanding of plants, people feel magical.

Culture method of Vanda orchid

Vanda orchids require more fertilizer than other orchids, so dilute fertilizer can be applied every 7 to 10 days during vigorous growth. The best fertilizer is nitrogen, phosphorus and potassium in a ratio of 10:10:5. Because the root of Vanda orchid belongs to aerial root, any medium with good drainage can be applied, such as snake sawdust, broken brick, charcoal, coarse gravel sand, etc., whether used alone or in combination, it is a good basin soil. In addition to the medium, the pot for planting Vanda orchids must also be very careful. Among the pots made of various materials, wooden battens and pottery pots are preferred, and several holes are perforated in the pots, which is more conducive to good drainage and air circulation. In addition to wooden battens and pottery pots, Vanda orchids can also grow well on snake boards or tree trunks. Vanda orchids should not be changed frequently, unless they are infested by pests and diseases, otherwise they can only be changed once every at least 3 years.

Spring Vanda is about to enter the vigorous growth period, is a good time to change pots. The root system of Vanda orchid, which has grown for many years, will be tightly attached to the inner wall of the pot. Therefore, if it is planted in a pottery pot, it is best to break the pot and change the pot to avoid damaging the root system when taking out the plant.

Finally, no matter what kind of cultivation method is used, remember that the pot soil must be drained and ventilated very well.

Vanda can be propagated in tissue culture or high bud propagation. However, the former is not suitable for home propagation because it requires more professional skills. At the end of autumn, Vanda orchid will grow high buds in the axils of leaves. When the high buds grow to 5~7.5cm, use sharp and sterilized knives to cut off the high buds from the mother plant and plant them in pots filled with snake sawdust. They can be transplanted to larger pots. Remember to apply medicine to the incision to prevent infection.

In addition, when the plants cultivated for many years grow to more than 1m, you can cut off the terminal buds about 30~46cm long, apply medicine to disinfect the cuts on both sides, and then plant them in pots and keep them moist. Pest control Tough leaves are the main reason why Vanda orchids are less susceptible to pests. Common pests, except snails and slugs, are less common on robust Vanda orchids. But when water stays in the leaves for too long, or is infected by viruses, dark spots or patches often appear and decay gradually. If the condition is mild, the affected part can be excised. In case the area of decay is too wide, the whole orchid must be discarded so as not to infect other orchids.
