Dendrobium flowering management
This article introduces the content about the orchid plant Dendrobium, focusing on the management of its flowering period. Let's take a look together!
Dendrobium is a precious variety of tropical orchids, known for its numerous and brightly colored flowers. It is one of the largest genera in the orchid family, with over 1000 native species. The flowering period of Dendrobium is from January to June, lasting up to half a year, so its management during the flowering period is very important.
Temperature Control: Dendrobium is native to the tropical region of the Pacific and prefers a warm environment with significant day-night temperature differences and avoids direct sunlight. Therefore, in winter, it should be placed in a semi-shaded greenhouse, with night temperatures controlled between 13°C and 15°C, and day temperatures between 18°C and 20°C, to promote the differentiation of flower buds. If the minimum temperature is below 5°C, it not only affects flowering but can also cause the leaves to fall off successively.
Maintaining Humidity: Dendrobium thrives in humid conditions and has poor drought resistance. It is necessary to frequently spray water around the plant to maintain a higher air humidity of 60% to 70%. If the humidity is insufficient, the leaves are prone to yellowing and wrinkling, which directly affects flowering.
Timely Fertilization: After entering winter, Dendrobium should be fertilized less frequently, preferably with phosphorus, potassium, and a moderate amount of nitrogen fertilizer to promote flowering. However, fertilization should be stopped once flower buds appear. Starting in May, resume fertilizing every two weeks with a thin, decomposed cake fertilizer water to promote growth.
Proper Ventilation: Dendrobium has high requirements for plant ventilation. Its medium should be made of breathable materials such as bark, charcoal, and broken bricks, and indoor air circulation should be maintained.
Preventing Pests and Diseases: Dendrobium is susceptible to red spider mites, which can be controlled by using a 1000-fold solution of trichlorfon, or by spraying with a 40% dimethoate solution every other week for 2 to 3 times.
