Dendrobium lindleyi is widely distributed in Southeast Asia, including Sikkim, Bhutan, north-east India, Burma, Thailand, Laos, Vietnam and south-west China.
Dendrobium lindleyi also called as Lindley's Dendrobium, Callista aggregata, Dendrobium aggregatum, Dendrobium alboviride var. majus, Dendrobium lindleyi var. majus, Epidendrum aggregatum, is a species of the genus Dendrobium. This species was described by Ernst Gottlieb von Steudel in 1840.
IDENTIFY DENDROBIUM LINDLEYI
Dendrobium lindleyi is widely distributed in Southeast Asia, including Sikkim, Bhutan, north-east India, Burma, Thailand, Laos, Vietnam and south-west China. In Thailand, they grow in the mountains in the north of the country, at the heights of 650-1400 m, but they are also occurs in the southern and south-central regions. They usually grow on the branches of the trees that lose their leaves before winter.
It is a miniature to small sized, hot to cool growing epiphyte, which reaching a height of 10-20 cm, with erect, clustered, thickened upwards from a slender base, almost spindle-shaped, angled, 5-10 cm long stems carrying a solitary, oblong, leathery, obtuse, 7.6 cm long leaf.
Lindley's Dendrobium blooms in the winter and spring with fragrant flowers on an axillary, 5 to 15 flowered, often pendant raceme that arise from nodes at the middle of the leafed or leafless cane. The flowers are 2.5-5.0 cm in diameter. The round, flat petals of both whorls can be almost white to deep orange, but they are usually yellow. Over time, the color deepens. The lip is usually orange-yellow and is darker at the base. It can be very colorful even when the petals of both whorls are bright.
DENDROBIUM LINDLEYI CARE AND CULTURE
Cultural information should only be used as a guide, and should be to be adapted to suit you. Your physical location; where you grow your plants, how much time you have to devote to their care, and many other factors, will need to be taken into account. Only then can you decide on the cultural methods that best suit you and your plants.
Light:
Dendrobium lindleyi needs a light level of 35000-45000 lux. This plants require very bright light and strong air movement. The level of light is so high that the plants can tolerate without allowing leaves to burn. It is possible to grow this species on a sunny window sill, but flowering when growing in artificial light is almost impossible.
Temperature:
The average temperature of the summer day is 26-28 ° C, the night 19-20 ° C, giving a daily difference of 7-9 ° C. In spring, the average temperature of the day is then 30-31 ° C, the night 12-19 ° C, and the daily difference is 11-18 ° C. In winter the average day temperature is 25-28 ° C, night 9-10 ° C, with a daily difference of 15-18 ° C.
Humidity:
Lindley's Dendrobium needs the humidity of almost 80-85% in the growing season, but in the winter and early spring it drops to 60-65%.
Substrate, growing media and repotting:
Dendrobium lindleyi are best mounted on rootstocks of wood or tree ferns, because this corresponds to the climbing plant cut. You can add a sphagnum pillow between the washer and the plant. If the plants are mounted, it is necessary to ensure high humidity and watering in summer at least once a day. If they are grown in pots or baskets, any loose, fast-drying substrate should be provided. The containers should be large enough to accommodate the root ball. Mounting plants or baskets reduces the risk of slender new shoots breaking under their own weight.
Repotting should be performed as rarely as possible, but it must be done before the substrate begins to decompose. The plants should not be divided into clumps smaller than 3-4 increments.
Watering:
Dendrobium lindleyi should be constantly moist during the growing season from spring to early autumn, but when the new growth reaches maturity at the end of autumn, the amount of water should be gradually reduced.
Fertilizer:
It is recommended to use a 1/2 dose of fertilizer for orchids every week. From spring to mid-summer, high-nitrogen fertilizer enriched with micronutrients should be used, and then until the end of autumn fertilizer enriched with phosphorus.
Rest period:
Dendrobium lindleyi will bloom even if in the winter the night temperature is 16 ° C, if a dry resting period is ensured. The plants will however be healthier if these temperatures are around 10 ° C. A cold, dry rest is necessary to initiate flowering. The plants that do not pass this rest produce keiki instead of flowers.
You can completely eliminating water in winter, but the plants are healthier if during the most of this winter period they are dry out between waterings and will not dry for too long. Within 1-2 months at the end of winter, the plants should then dry completely between waterings and stay dry longer. Occasional morning fogging between waterings should protect the plants from complete drying.
The dry rest should last until the flower stems reach 2.5 cm in length. Fertilization should be eliminated until spring, when more watering is undertaken. The level of light in winter should be as high as possible.
