Prune Dendrobium orchids between November and May, depending on which one it is. After flowering the older stems which carried flowers are usually cut down low as new stems replace them. Repot when the pot is full of roots.

Orchids are a diverse and popular family of flowering plants, with over 30,000 species and thousands of hybrids. They are found on every continent except Antarctica and are known for their intricate and often fragrant flowers. Orchids have been cultivated for centuries for their beauty, and they are now one of the most popular houseplants worldwide.
Orchids come in a wide variety of shapes, sizes, and colours. The flowers can be small or large, and they come in a range of colours, from pure white to deep purple. Some orchids have striking patterns or unusual shapes, such as the slipper orchid. Orchids are also known for their unique reproductive structures, which include a specialised lip or "labellum" that acts as a landing pad for pollinators.
Orchids can be grown both indoors and outdoors, but they require specific growing conditions. Most orchids prefer bright, indirect light and high humidity. They also require a well-draining growing medium, such as bark or sphagnum moss, and regular watering. Orchids should be fertilised regularly during the growing season with a specialised orchid fertiliser. Some orchids, such as Phalaenopsis, are relatively easy to care for and are good for beginners, while others, such as Cattleya, require more specialised care.
Orchids are primarily grown for their ornamental value. They are popular as houseplants and are often used in floral arrangements. Some orchids, such as Vanilla, are also grown commercially for their flavour and scent. Orchids are also important in traditional medicine and are used to treat a variety of ailments, including coughs, fevers, and infections.
Many species of orchids are threatened by habitat loss, over-collection, and other factors. Some orchids, such as the Ghost Orchid, are extremely rare and may be on the brink of extinction. Orchid conservation efforts include habitat protection, captive breeding, and efforts to combat illegal trade in wild orchids.
Orchids are a fascinating and beautiful group of plants with a rich history and a wide range of uses. Whether grown for their ornamental value, their medicinal properties, or their commercial value, orchids are an important and beloved part of the natural world. Conservation efforts are needed to protect these plants for future generations to enjoy.
