The larvae become very active and mobile immediately. They start feeding on the plant’s tissues and extending their target to the parts below the potting mix. However, thrips do not survive in high humidity conditions and cooler weather. They usually become active in summer when humidity is relatively low, and temperatures are high. These Dendrobiums resemble the Moth Orchids (Phalaenopsis). They are the most common type of Dendrobium in the marketplace. They are warm growers with thin, tall pseudobulbs, up to 20 terminal inflorescences gracefully hanging down, usually blooming in the fall or twice a year. They include species such as Den. affine, Den. bigibbum, Den. dicuphum and Den. williamsianum. How to care for a dendrobium nobile orchid: Keep in bright light, at 65-85 °F (18-30°C) and 50-70% humidity. Plant in orchid potting mix, water when the top of the potting medium is dry and fertilize lightly every 1-2 weeks. Prune after flowering. How often do you water a Dendrobium orchid?

The best time to prune your beauties is during the growing season as this allows the plant to heal and produce new growth at a faster rate. When grown indoors, space may be limited as your orchid matures, so prune off the messy foliage to keep it neat.Additionally, using natural pest control methods such as neem oil spray or introducing predatory insects like praying mantises and lacewings into your garden can help keep unwanted bugs at bay without resorting to harmful chemicals.

There are two types of Dendrobiums; those that produce flowers along the shaft in between the leaves ( N obile), and others that produce a spike at the top ( Phalaenopsis). The flowers can last up to two months and can bloom at any time, most commonly during late winter. The best way to tempt any Orchid into flowering is by reducing the temperature in the winter; have a read of the 'Dormancy Period & Annual Flowers' above for more information on this... When you plant your orchid put it in a small pot. Orchids prefer smaller areas that compact their roots. This preference is due to their epiphytic nature. They produce smaller root systems so they can thrive in smaller environments. It takes a month or two, or even several months for Phalaenopsis orchids to rebloom. Many other varieties of orchids bloom annually. What to do with an orchid after the flowers fall off? Often, it’s as a result of temperature change. When winter arrives, many orchids start to flower, or it can be as simple as a change in temperature between night and day.” Dendrobium blooms are easily achieved when its dormancy irrigations are reduced by half; those who have a cooler room without artificial light at night will also be on the upper-hand. Keep the roots pot-bound to add further stress onto the specimen, which in turn will significantly heighten the chance of flowering. Blooms will generally appear in the late winter, but may occur at any given time.Warm-growing species will need to be watered throughout the winter too, but cool-growing species can be kept drier, as they enter their winter dormancy period – it is essential to research the requirements of your particular variety. Overwatering or excessive moisture around your plants causes their leaves to turn yellow . However, it is widespread for old mature leaves to turn yellow before they fall off. Therefore, you must carefully distinguish between the yellowing caused by excess moisture and leaf maturity. Fertilize your orchid once or twice a month using a balanced houseplant fertilizer at half strength. … We recommend that you loosen the soil after a few waterings so that it does not get compacted. Also, flash the potting medium regularly with distilled water to get rid of excess salts caused by fertilizers. Temperature Requirements Because there are thousands of species of dendrobiums, they can vary slightly in what care they prefer. But they do have some similarities and general care requirements, which we will explore below.
