The Ultimate Guide to Orchids

Discover facts, types, care tips and the meaning of this striking flower

Distinctive, bright and beautiful – there are a lot of reasons orchids are so popular. But they do have a bit of reputation for being tricky to care for, a reputation that really isn’t deserved. All an orchid needs is the right TLC and it can last years and years. Stick with us and we’ll fill you in on how, with this guide to all things orchid, from how to keep them thriving to the different types.

Did you know?

  • There are around 28,000 species in the orchid family, or Orchidaceae to give it the proper scientific name!
  • There’s an orchid that looks exactly like a bee (called the bee orchid, of course)
  • Orchids are usually tropical plants, but there are at least four species living north of the Arctic Circle

Orchid meaning: what do orchids symbolise?

Like many blooms the meaning of an orchid might change according to its colour, so a white orchid might signify innocence, while red can indicate passion. What all orchid’s symbolise though is a refined beauty. This idea emerged during the Victorian period when these expensive flowers were worn by those dressing to impress. A favourite for gent’s buttonholes the orchid combined was striking but simple: a guaranteed eyecatcher.

Orchid Types

Here's some of the most popular varieties available to buy in the UK:

Vanda Orchid

Vanda orchids require a great deal of water. Keep them moist at all times but avoid over-watering.

Phalaenopsis Orchid

Phalaenopsis orchids generally require brief dry periods between every watering.

Cymbidium Orchid

Cymbidium orchids need their soil to be evenly moist at all times. Be careful to ensure the soil is not soggy or wet.

Dendrobium Orchid

Dendrobium orchids require evenly moist soil during growth but also need a brief dry period between watering when it is not growing.

How to water

Although orchids are commonly found growing wild in tropical rainforests, they do not need heavy watering.

In fact, the most common way people harm an orchid is by over watering. When it comes to watering an orchid, the golden rule is to ensure the plant is not constantly sitting in water so that it causes the roots to rot.

Here are three ways you can water an orchid plant...

Ice cubes

Yes, that's right. Ice cubes straight from a small/medium sized ice cube tray are a great way to water orchids. 'Why would you use ice cubes?' we hear you ask. Well using ice cubes will...

  • Improve absorption
  • Prevent root rot
  • Avoid overwatering
  • Make life easier!

How often should you water with ice cubes?

  • Depending on the season and where the orchid is kept, pop one cube twice a week on top of the potting medium underneath the leaves.
  • Be mindful to ensure no water is left standing in the pot and if possible, remove any excess water if you notice any water pooling on the orchid. You can also tell that there is too much water if the pot has become very heavy and sloshes when you tilt it.

How to tell when to water orchids

Watering can be a little bit of trial and error. Keep in mind that long summer days may require you to water the orchid more and short winter days will require less watering.

Here's how to tell if the orchid needs water:

  • Roots that are green are getting just the right amount of water
  • Roots that are soggy and brown are getting too much water
  • Roots that are grey or white are not getting enough water

Another easy way to judge if the orchid needs watering is to use your finger to poke deep into the pot:

  • If the mix is wet or damp - don't water it
  • If the mix is dry - water it

Humidity

Humidity is important as it recreates the conditions of an orchid's natural habitat, which of course helps them thrive.

There are multiple ways of creating ideal humidity for your plant but by far the easiest method for indoor orchids is to mist them regularly.

What is Misting?

  • Misting is simply spraying an orchid regularly with a fine mist spray bottle.
  • Spray the orchid leaves and any aerial roots up to two times a day depending on the plant's location in your home. This may sound like a lot but water very quickly evaporates. Do a finger test if you're worried about overwatering.

Avoid plain tap water

If possible, use distilled or water boiled in the kettle and cooled for your mist bottle. Standard tap water is laden with impurities, which can cause the orchids leaves to become covered in white crust. This can be unsightly and can also block moisture from entering the leaf.

How to tell when to mist

Insufficient misting and lack of humidity can lead to a few problems. If you notice any of the following, increase your misting:

  • Stunted growth
  • Falling flower buds
  • Brown-tipped leaves
  • Twisted flowers

Ideal light for orchids

Like most plants, optimal light is the absolute key to keeping orchids happy.

Avoid Direct Sunlight

Under no circumstances, place the orchid in direct sunlight, as they will get sunburnt - yes, really!

It can happen in a matter of hours, so keep your eyes on the light the orchid is receiving.

An ideal place for the orchid to live is in a room that stays at a consistent temperature through the day, away from drafts, fruit and where it can receive indirect sunlight.

What's indirect sunlight?

Indirect sunlight is simply sunlight that has been filtered by bouncing off a wall or through an object before hitting the orchid. If you're unsure if your location is suitable, the simplest way of measuring light intensity is to use your hand. It sounds strange but, at the height of the day, when the sun is pointing through the window at its brightest (a bright day is best to try this rather than overcast), put your hand a few inches above the plant’s leaves so that you cast a shadow over the plant.

How to prune orchids

How Often Do Orchids Need Pruning?

When the orchid peaks its blooming period, its new flowers will last up to 12 weeks. After this time, they may fade, droop or fall off their stems (spikes) when they are spent.

Once they do this, you will need to determine how to prune the orchid. First, check if the stem is healthy or in poor condition:

Orchid Pruning Tips

Cutting back an orchid for the first time can seem daunting. Nevertheless, by following the next few tips, you should expect the orchid to produce their beautiful flowers for its next blooming cycle (providing all other care instructions are followed of course!).

  • Bear in mind when pruning that orchids are very fragile plants and canÂ’t be handled like you would a shrub. For example, if you partially cut an orchid leaf, the rest of the leaf may die as a result
  • With sterilised and sharp shears or a knife, trim away any dead leaves, tissue or roots as well as your stem
  • As a rule, if something is still green, it is living
  • When you make the cut, be sure to cut diagonally as shown

Orchid care FAQ's

Often people think because there are no flowers that an orchid is past its best. DonÂ’t worry, if the leaves are healthy then keep going. Often insufficient light causes orchids to concentrate their energy elsewhere. If the orchid has already bloomed, try pruning them.

Some loss of leaves for an orchid is natural, providing they donÂ’t all fall at once. Excessive leaf loss usually indicates that the plant is either kept too cold or is overwatered. Allow the plant to dry and remove the dead foliage.

This is orchid nectar which is created to attract insects to pollenate it. If you notice this in excess on the leaves, wipe it away with a damp cloth.

When new leaves grow from an orchid they tend to stick to one another if the atmosphere is too dry and crinkle. If you spot this, increase the humidity by misting.

Orchids commonly grow on trees with their roots exposed to a moist rainforest atmosphere so this is normal. Lots of aerial roots is a great sign that the orchid is happy in its environment. Spray these roots regularly with the misting technique to keep them green and healthy and not grey and dry.

Yellow leaves are either a sign of too much water or too little light. Check that your roots are not brown and waterlogged. If they are, hold off the water and allow the plant to dry. If your roots are healthy then try the plant in another spot to get more light. Also use the light measuring technique.
