Caring for your Oncidium orchids

Oncidium orchid

These lovely epiphytic orchids originate from South America upwards through Central America and as far north as Mexico.  They are also present in the islands of the West Indies.  Unlike other orchid species, they grow well in regions other than their native ones, and many thousands of plants are cultivated in South East Asia for use as pot plants and cut flowers.  orchids are epiphytic and grow in trees. When kept in the home they need a steady warm temperature with plenty of indirect light and should be watered once a week.  The plants are generally compact and should flower every year, often producing two flower stems at a time if properly cared for.

Watering your orchid pot plants

By far the best way to water orchids is to place them in a sink or other container of lukewarm water which comes up to the top of their pots.  Because they are not growing in densely packed soil or compost, the water will easily rise up from the bottom of the pots and saturate the roots.  The plants should be left for several hours, or overnight, and the watering should be repeated on a weekly basis (although most plants will easily survive a 10 interval if you are away).  At the same time as watering, spray the leaves with a fine water mist.  Feeding should be kept to a minimum and stepped up only once new growth or flower shoots appear. Never overdo it – food is not high on the agenda of survival for plants that live perched up in trees with their roots exposed!

What about our native wild orchids?

Yes, we have many native wild orchids throughout Europe and around 30 species in the UK.  Most of them are rare, endangered or in serious decline due to the destruction of their natural habitats. They will not survive being dug up and moved either to gardens and greenhouses or to window ledges. It is also an offence under the Wildlife and Countryside Act to dig up any wild plants without the landowner’s consent.

Where to see wild orchids

There are many local and national nature reserves where wild orchids can be seen at the right time of year, and the network of local Wildlife Trusts can advise you on the best time to visit and also arrange for you to take part in some of the many tours that they organise during peak flowering times.
