Vanda hindsii
Also known as: Hinds' Vanda or Vanda truncata Vanda hindsii h.f. lutea Vanda whiteana The Native Strap Orchid in the subfamily: Epidendroideae
Native to: Queensland - Australia
General Information
Hinds' Vanda is a large monopodial warm to hot growing epiphytic or lithophytic orchid belonging to the sub family Epidendroideae native to Australia. It is named after the English Botanist early in the 19th century.
Plant Description
Monopodial. Grows to 0.8-200cm. Each new growth has numerous leathery arching, rigid leaves that grow to 1.8-40cm long
Substrate(s)
- Coarse
- Charcoal
Care Notes
This orchid goes into a dormancy phase during winter, during this phase it is best not to provide water unless the plant is starting to look thirsty. The lack of water increases the chance of flowering in spring, and also reduces the likelihood of any rot forming. Do not resume watering until new growth has appeared and is growing strongly.
Often a period of intense growth occurs after dormancy. During this time the amount of light, water and fertiliser the plant receives will directly impact the amount of growth that occurs during this time, and in the case of seedlings, will reduce the time required to reach maturity.
It's recommended to heavily reduce the water amount at the middle to end of autumn to trigger dormancy. Leaves on older bulbs will begin to drop during this time while the newer bulbs continue to mature until terminal leaves appear at the tip of the pseudobulbs.
Repotting can be done any time of the year though it's best to do it in early spring when new growth is appearing as this also means new roots will appear to help the plant anchor into the new media and offset any damage to established roots during the repotting process.
Climate
These orchids grow in cool climates, at low altitudes, in cool plains, forests or coastal scrub.
They are forgiving of humidity variances as long as temperatures are kept on the cool side. They can do well outdoors in the garden in cool and temperate areas, though it is important that they are protected from warm dry winds. They can enjoy morning sun especially in winter but will need protection from the hot sun in the afternoon and during summer. With some acclimatisation they may be able to receive more sun.
Grows at low elevations. Rainfall ranges from 18mm to 262mm per day, heaviest in July and lightest in February. Humidity ranges from 79% to 91%, highest in August and lowest in May. Temperature ranges from 21C to 33C, highest in May (23C to 33C) and lowest in March (21C to 29C).
Watering
These orchids gather most of their water from their aerial roots, which should be sprayed regularly or kept in a humid environment; roots exposed to dry air that receive no water will die back. On that same note, roots that are inside a pot surrounded by media may also die back, with new roots growing from the stem away from the pot.
If outdoors, a misting system aimed at the roots that turns on regularly will help them grow, otherwise if indoors placing the roots inside a vase or pot with no media along with regular spraying should give them the moisture they need.
Fertiliser
These orchids do not need to be regularly fertilised and roots may be sensitive to salt build-up, dying back and therefore impairing the plants growth or even killing it.
If fertilising, use half to quarter of the recommended amount of fertiliser. If they receive fertiliser as part of a collection, be sure to flush out the pots regularly with fresh water and monitor the roots by checking how much resistance is given by the plant when nudged in its pot or mount. If the plant becomes wobbly or loose, repot in fresh mix or rinse the media/mount thoroughly and do not fertilise for at least 3 months.
Apply fertiliser regularly at half strength year round. This plant is sensitive so apply fertiliser sparingly at one quarter recommended strength or less. Use a high Nitrogen fertiliser during Spring and Summer. Use a high Phosphorous fertiliser during Summer.Potting
These plants are quite forgiving and will do well repotted ever 2-3 years. The mix should be coarse, well draining, and allow space for air to move and for roots to grow.
Alternatively, these plants will also do well mounted to tree fern or cork slabs, or mounted to trees.
Best time for repotting or mounting the orchids is the end of winter when new growths start to appear. Avoid repotting during hot weather,
This plant does very well in baskets or suspended pots
