Psygmorchis pusilla care infographicPsygmorchis Pusilla is often called the ideal bathroom plant because of its small size and high humidity requirements. In this blog post, we equip you with all the information you will need to grow healthy and vibrant pusilla orchids. So, what are you waiting for? Carry on reading to find out more!

What Is Psygmorchis Pusilla?

Psygmorchis Pusilla is a tiny orchid species from the hot, damp forests of Central and South America. As a typical epiphyte, it grows on trees, shrubs, and bushes at an altitude of than 800 yards or less.

Moreover, here are a few more details on the plant:

  • Pusilla is a very small-sized orchid and grows from 1.5 to about three inches in size maximum.
  • Its flowers bloom from autumn to spring on a less than one inch long inflorescence. Each individual flower is one inch across in diameter, but appears large in comparison to the rest of the plant.
  • The flowers are yellow-colored and speckled with brown spots.
  • Numerous lean leaves of about three inches in length can be seen emerging from the stem. The foliage is arranged in a beautiful fan-like pattern.

Psygmorchis Pusilla Care

– Light

Since Psygmorchis Pusilla is an indoor plant, its light requirements are very simple.

  • Put them indoors under bright indirect or filtered light.
  • Do not expose them to direct sunlight, especially during afternoon hours. These orchids are particularly vulnerable to sunburns.
  • Avoid putting them near windows. If you do want to decorate your windows with it, use curtains or blinds, or choose a shaded window for that matter. 
  • Artificial light works just as efficiently as natural sunlight. Use a light fixture that provides 20,000 to 30,000 lux of light. Keep this light at least 12 to 15 inches away from these orchids.

– Water

A large part of growing Psygmorchis Pusilla to be healthy depends upon watering it the right way. Learn the water needs of your orchids along with how to fulfill them below.

Psygmorchis Pusilla Growth depends upon watering

  • During the active phase, water Psygmorchis Pusilla abundantly and thoroughly. However, make sure not to overwater it and do not let the soil and the potting media become clumped around the roots.
  • Always make sure that your orchid has adequate drainage. Water should flow off the surface of the growth medium and not stay there. This is especially important if you plant your orchids in pots. Buy pots that are breathable and have drainage holes in the bottom.
  • When the active phase of Pusilla ends — around the start of autumn — decrease the watering frequency.
  • Many gardeners find that they need to water Psygmorchis Pusilla daily during the active period and then decrease this frequency to every other day during winter.
  • It would be best if you can use reverse osmosis or any other filtered, clean water to give to your orchids. However, you can use common tap water too, provided that it is not too laden with chemicals and toxins.

– Soil

Psygmorchis pusilla orchids are epiphytes in nature. They grow on larger ferns and trees by deriving support, protection, and strength from them. Our orchid experts suggest growing them bare-rooted but you can also grow them in pots. 

– Growing on Corks and Baskets

Growing this orchid by mounting them on pieces of cork or hanging down in baskets mimics the way they grow in nature.

  • If you grow Pusilla bare-rooted, you will need to give them more water as there will be no soil to retain moisture.
  • Bare-rooted orchids need more humidity than potted ones. You will need to use a humidifier around them or mist them regularly.
  • If the weather is hot or humid, your mounted Pusilla will need to be watered and misted even more than once each day.

– Growing in Pots

 Although it is not ideal, Pusilla can also be grown in pots.

  • Choose a potting medium that drains excellently and rapidly.
  • Use a coarse substrate for the mixture.
  • Never allow your potting medium to become decomposed. This can lead to the retention of more water than is beneficial for this orchid. Decomposed soil around their roots is something Psygmorchis Pusilla orchids do not tolerate. Replace the medium as soon as it starts to rot.
  • Choose a small-sized pot, as it will be well-suited for these tiny orchids.

– Temperature

Maintaining the right temperatures for your orchids is crucial for their proper growth and flowering. Orchids thrive best when they are grown under conditions similar to their native ones.

  • During summer, the ideal daytime temperatures are 86 to 88 degrees Fahrenheit. At night, the temperature should drop to 71 degrees Fahrenheit.
  • On the other hand, during winters, the temperatures should be from around 68 to 75 degrees Fahrenheit during the day and around 60 degrees Fahrenheit at night.

– Repot: When and How

You should replace the soil and potting medium of your orchids when it begins to become stale around the roots. This is because this orchid has a very low tolerance for such conditions.

Remember that the timing is important: Wait till new roots emerge before you repot. This will allow the plant to adjust better to the new potting medium.

Psygmorchis pusilla seeds are quite difficult to plant and grow adult plants out of. You will need to put them in flasks with a suitable nutrient mixture under the right culture conditions.

Even then, many times this orchid fails to grow properly. The life span of an average Pusilla is quite short. Repot and propagate old ones using tree fern or sphagnum moss.

– Fertilizer, Feed, and Humidity

  • Give Psygmorchis Pusilla orchid a feed-in type of fertilizer once every week during the active growth period.
  • Mix only one-quarter to one-half the recommended strength given on the label.
  • We suggest mixing the fertilizer in about a liter of water and letting it sit in the pot for about an hour. For mounted orchids, you can let the water simply flow through the plant.
  • For most of the year, ensure humidity levels around 75 to 80 percent. During winter and spring, 65 to 70 percent humidity is adequate too.

Diseases and Infestations

Like all other orchids, Pusilla species are susceptible to many common plant diseases and insect infestations. The major threats come from some species of pests, insects and bugs, such as mites, aphids, beetles, and thrips. Your Pusilla can also get infected by plant viruses.

Diseases and Infestations Problems

These bugs feed on the leaves and flowers of the plant. This leads to stunted growth, failure of the flowers to bloom, and causes the leaves to turn a sickly yellow or brown. Fungal infections can occur when the soil does not drain properly and water stays on the stem and leaves for prolonged periods.

For preventative and treatment measures, read our advice given below.

  1. First of all, the best way to prevent any type of pest infestation or infection is to make sure that all the cultural needs of the plant are being fulfilled. Be vigilant about providing the ideal light, water, humidity and air circulation requirements to your orchids.
  2. The second thing you should do to get rid of bugs is to ensure adequate cleaning and pruning of your plant. Regularly remove old leaves and decomposed potting medium. Also, remove old leaf sheaths from the stems to get rid of the hiding and breeding places of mites and beetles. Use water spray to dislodge insects that stick stubbornly to your orchids.
  3. If, despite all precautions, you do suffer from a persistent infestation, then you will need to buy and use an insecticide or pesticide. Keep in mind that not all insecticides can be used on orchids. Always read and follow the instructions given on the label.
