The cultivation method of Vanda orchids
Introduction: Topics related to the cultivation of Vanda orchids at home, the cultivation method of Vanda orchids, detailed information is as follows:
Vanda orchids originally come from the Sanskrit language of the Indian region, meaning orchids that hang on trees. They are very special orchids that can grow vigorously without soil or any other planting materials. They are air-rooted orchids, relying solely on aerial roots to absorb oxygen from the air. In the wild, they grow attached to tree trunks or rocks, which seems to transcend our understanding of plants and makes them magical.
Vanda orchids require more fertilizer than other foreign orchids, so during the period of vigorous growth, diluted fertilizer can be applied once every 7 to 10 days. The best fertilizer has a nitrogen, phosphorus, and potassium ratio of 10:10:5. Since the roots of Vanda orchids are aerial roots, any well-draining medium can be used, such as bark chips, broken bricks, charcoal, coarse gravel, etc. Whether used alone or mixed, they all make good potting soil. In addition to the medium, the pot is also quite particular. Among various materials, wooden and ceramic pots are the best. Adding more holes to the pot is more conducive to good drainage and air circulation. Besides wooden and ceramic pots, Vanda orchids can also grow well on snake木板 or tree trunks. Vanda orchids should not be repotted frequently, unless affected by pests and diseases, otherwise, they should be repotted only once every 3 years.
In spring, Vanda orchids are entering a period of vigorous growth, which is a good time for repotting. For Vanda orchids that have been growing for many years, their roots will tightly adhere to the inner walls of the pot. Therefore, if they are planted in ceramic pots, it is best to break the pot before repotting to avoid damaging the roots when removing the plant.
Finally, no matter what method of cultivation is used, it is important to ensure that the potting soil has very good drainage and aeration.
Propagation of Vanda orchids can be done through tissue culture or keikis. However, the former requires more professional skills and is not suitable for home use. In late autumn, Vanda orchids will grow keikis in the leaf axils. When the keikis grow to 5 to 7.5 cm, they should be cut from the mother plant with a sharp and sterilized knife and planted in a pot with snake bark chips. They can be transplanted to a larger pot. Remember to apply medicine to the cut to prevent infection.
Additionally, when a plant cultivated for many years grows to over 1 meter, you can cut off the top bud, about 30 to 46 cm long, and apply medicine to disinfect both sides of the cut before planting it in a pot. Keeping it moist is sufficient. Disease and pest control: The tough leaves are the main reason why Vanda orchids are not easily affected by diseases and pests. Apart from snails and slugs, common pests rarely appear on strong Vanda orchid plants. However, if moisture accumulates on the leaves for too long or if infected with a virus, dark spots or patches may appear and gradually rot. If the situation is mild, the affected area can be removed. If the rotting area is too extensive, the entire orchid plant must be discarded to prevent infection of other orchids.
The above is an introduction to the cultivation method of Vanda orchids, which can be used as a reference suggestion.
