How to water it
The Vanda orchid is a plant that needs a considerable amount of water and the maintenance of a high humidity. It is recommended to wet the plant every day during spring and summer, especially if the Vanda orchid is grown in hanging baskets. During the cold season it is good to reduce the frequency of wetting by paying attention to the substrate and keeping it always moist. Furthermore, the Vanda orchid needs a humidity level of 80% and for this reason it is advisable to spray water around the crown once or twice a day. It is good to use non-calcareous water at room temperature for both irrigation and nebulisation. Finally, as regards the process of wetting the foliage, it is good to proceed during the first hours of the day.
How to cure it
The Vanda orchid is a plant used to warm climates. As a result, it does not withstand temperatures below 14 ° C. In case of excessive heat, it is good to put the Vanda orchid in a rather ventilated environment in order to prevent the leaves from drying out. This plant needs a high amount of light to grow well. By guaranteeing these conditions, it is possible for the plant to flower even three times a year with blooms that manage to last quite a long time. The Vanda orchid can produce from the main stem some lateral shoots that will be able to give life to new seedlings emitting roots and developing independently from the mother plant. These plants will be detached and planted by themselves once the development of the root system has been completed.
How to fertilize it
The Vanda orchid is an epiphytic plant. This type of plants do not have their roots in the soil and therefore require special attention regarding the fertilization process. Generally, it is advisable to spray the fertilizer around the crown of the Vanda orchid. During the hottest period, between spring and summer, it is good to fertilize the plant about once a week. During colder periods, the Vanda orchid can also be fertilized once every two weeks. As far as fertilizers are concerned, it is good to avoid those with a high nitrogen content that tend to inhibit flowering. On the other hand, fertilizers with balanced levels of phosphorus, potassium and nitrogen are to be preferred in a proportion of 20:20:20. These fertilizers must be diluted in irrigation water with doses of about 1 g per liter of water. When the Vanda orchid is fertilized once a week it is good that it is subsequently watered only with water in order to eliminate excess mineral salts.
Vanda Orchid: Diseases and Remedies
The diseases that affect the Vanda orchid are generally linked to poor plant care. For example, excessive wetting may cause the leaves to fall. Conversely, poor watering could lead to flower fall or an arrest in their growth. Bad lighting could completely inhibit flowering or excess light could cause burns on the leaves of the Vanda orchid. As for the parasitic diseases, the plant could be affected by the cochineal which manifests itself in the form of brown spots on the lower side of the leaves. The most useful method to eliminate them is to use an alcohol swab to pass over the areas affected by the parasite. The Vanda orchid can also be attacked by aphids. These parasites cause yellowing of the leaves and can be counteracted by the use of specific pesticides.
