You may think that miniature orchids require less care than larger orchids due to their size. It’s actually just the opposite, and in fact, they require even more attention.

You may be wondering why that is…it’s due to a few reasons.

Because they are potted in small pots where the moisture evaporates faster than in larger pots, and because they have very fine roots, they tend to dry out very quickly and will need to be watered and misted quite frequently.

Also, if your orchid becomes infected with pests or disease it needs treatment right away otherwise it can be disastrous.

Because of a mini’s small stature, pests and disease can overtake them very rapidly, so you will need to be vigilant with checking your orchid’s health. So how mini can miniature orchids be?

Certain species produce flowers so minute (only a few millimeters) that in order to really get a good look, you need to pull out a magnifying glass!

The Platystele jungermannioides orchid (believed to be the smallest orchid in the world) has flowers that are only two millimeters in width! It’s blooms are so thin that they’re nearly see-through.

Other wild orchid species reach a height of only a few inches and their flower spikes are often at least twice as tall as the plant itself.

Some miniatures even produce blooms that are almost larger than the actual plant.

Some mini orchids do very well grown in a vivarium, which is an enclosed area that allows light to penetrate while maintaining consistent climate conditions inside.

Some examples of vivariums that can easily be set up in your home or apartment are terrariums, aquariums, and Wardian cases. Before you set up your own, make sure that your type of mini is one that will do well in a vivarium and be sure to include materials that will help prevent mold from growing in the moist environment.

A great thing about vivariums is that not only can it help your mini orchid thrive, but it is a great way to display your tiny beauty.

When looking for a mini orchid it’s best to shop at a reputable orchid nursery or online seller because they will be able to tell you how to properly care for the particular mini that you purchase.

You can also find them at big box stores. The orchids sold in these stores are usually hybrids that have been bred for hardiness, which makes them great beginner minis. The mini Phalaenopsis orchid is one of the most common you will find.

How To Care For The Miniature Orchids?

Here’s a guide to help you care for and appreciate these lovely miniature orchids:

Selecting the Orchid:

  • Look for healthy plants with vibrant leaves and undamaged stems.
  • Consider the specific care requirements of the orchid species you’re interested in.


  • Miniature orchids usually prefer bright, indirect light.
  • Place them near a north or east-facing window to provide the appropriate light levels.

Temperature and Humidity:

  • Most miniature orchids thrive in moderate temperatures ranging from 60-75°F (15-24°C).
  • Maintain a humidity level of 50-70% by misting the orchids or placing them on a humidity tray.


  • Orchids generally prefer slightly moist conditions. Water them when the top layer of the growing medium is dry.
  • Avoid letting the orchid sit in water, as it can cause root rot.

Potting and Growing Medium:

  • Use a well-draining orchid potting mix like bark, sphagnum moss, or perlite.
  • Repot the orchid every 1-2 years or when you notice overcrowded roots.


  • Use a balanced orchid fertilizer diluted to half strength during the growing season (usually spring and summer).
  • Reduce or stop fertilizing during the orchid’s resting period.

Resting Period:

  • Some miniature orchids go through a rest period during the winter or dry season. Reduce watering and fertilizing during this time.

Air Circulation:

  • Ensure good air circulation around the orchid to prevent fungal infections and improve overall health.

Pests and Diseases:

  • Regularly check for signs of pests like aphids, mealybugs, or spider mites, and treat promptly if detected.
  • Maintain good hygiene to prevent diseases.


  • Miniature orchids often produce stunning and delicate blooms despite their size.
  • Be patient, as some varieties may take time to bloom.

Support and Staking:

  • Use small stakes or supports to help the orchid maintain an upright position, especially if it tends to be top-heavy.

Remember, each orchid species may have slightly different care requirements, so it’s beneficial to research the specific type of miniature orchid you have to ensure the best care and blooming potential.

Before purchasing a mini orchid, be sure to do a little research to make sure you will be able to give it the care and attention that it will need to thrive. There are thousands of miniature orchid species around the world, so you have a wide variety to choose from when it comes to adding to your own collection…
