In this post, we’ll walk through the essentials of how to care for purple orchids, covering everything from light and water to potting and common mistakes.

Let’s dive into the simple steps that keep your purple orchid healthy and blooming.

Why Caring for Purple Orchids Matters

Purple orchids are a specific color variety of the Phalaenopsis orchid, also known as the moth orchid, and they share most care requirements with other orchids.
 
The main reason caring for purple orchids matters is that these plants are epiphytes, meaning they grow on trees in the wild, not in soil.
 
This unique growth habit means their roots need air circulation, and their watering needs are very different from typical houseplants.
 
When you learn how to care for purple orchids properly, you’ll notice they respond quickly to good habits with new roots, leaves, and flower spikes.
 
Let’s break down the key elements of purple orchid care so you can keep yours thriving year after year.
 

1. Light Requirements for Purple Orchids

One of the most important factors in caring for purple orchids is getting the light just right.
 
Purple orchids love bright, indirect sunlight, which mimics the dappled light they receive under a jungle canopy.
 
Place your purple orchid near an east-facing window where it gets gentle morning sun but is protected from harsh afternoon rays.
 
If you only have a south or west-facing window, use a sheer curtain to filter the light so the leaves don’t burn.
 
A good sign your purple orchid is getting enough light is when the leaves are a medium, healthy green rather than dark green or yellowish.
 
Too little light means your purple orchid won’t rebloom, while too much light causes leaf scorch.
 
You can also grow purple orchids under fluorescent or LED grow lights if natural light is limited in your home.
 

2. Watering Your Purple Orchid

Watering is where most people struggle when it comes to how to care for purple orchids, but it’s actually simple once you get the hang of it.
 
Purple orchids should be watered about once a week, but the exact frequency depends on your home’s temperature, humidity, and potting medium.
 
Before watering, always check the potting medium by sticking your finger about an inch deep—if it feels dry, it’s time to water.
 
When you water your purple orchid, run lukewarm water through the pot for about 15 seconds, letting it drain completely.
 
Never let your purple orchid sit in standing water, as this will cause root rot, which is the number one killer of these plants.
 
The roots of a healthy purple orchid are plump and silvery-green, and they turn a brighter green after watering.
 
If the roots look mushy or brown, you’re overwatering, and you’ll need to adjust your care routine immediately.
 

3. Humidity and Temperature for Purple Orchids

Purple orchids are tropical plants, so they need higher humidity levels than most indoor spaces provide.
 
To care for purple orchids properly, aim for humidity between 50% and 70% around the plant.
 
You can increase humidity by placing a tray of water with pebbles beneath the pot, making sure the pot doesn’t sit directly in the water.
 
Misting your purple orchid’s leaves in the morning also helps, but avoid misting the flowers themselves as this can cause spotting.
 
Another way to boost humidity is grouping your purple orchid with other plants, as they create a microclimate together.
 
In terms of temperature, purple orchids prefer daytime temps between 65°F and 80°F, with a slight drop at night.
 
A nighttime temperature drop of about 10°F actually triggers purple orchids to initiate new flower spikes.
 

4. Potting Medium and Repotting

Caring for purple orchids also means using the right potting medium, which should never be regular potting soil.
 
Purple orchids grow best in a bark-based mix that provides excellent drainage and air flow to the roots.
 
You can also use sphagnum moss, but it holds more water, so you’ll need to adjust your watering schedule accordingly.
 
Repot your purple orchid every one to two years, or when the potting medium breaks down and starts retaining too much water.
 
The best time to repot purple orchids is right after they finish blooming, so the plant can recover without the stress of producing flowers.
 
When repotting, choose a pot that’s only slightly larger than the current one, as purple orchids prefer being snug in their containers.
 
Gently remove old bark from the roots, trim any mushy or dead roots with sterilized scissors, and place the plant in fresh medium.
 

5. Fertilizing and Blooming

If you want your purple orchid to bloom repeatedly, fertilizing is a crucial part of orchid care.
 
Feed your purple orchid with a balanced orchid fertilizer, like a 20-20-20 formula, diluted to half strength.
 
During the growing season, which is spring through fall, fertilize your purple orchid every other week.
 
In the winter, reduce fertilizing to once a month, as the plant’s growth naturally slows down.
 
To encourage reblooming, make sure your purple orchid gets that cooler nighttime temperature we mentioned earlier.
 
Once the flower spike fades and drops its blooms, cut the spike back to just above a node (the little bump on the stem).
 
This node can produce a new branch with more flowers, extending your purple orchid’s bloom cycle.
 

Common Mistakes When Caring for Purple Orchids

Even with the best intentions, there are a few common missteps that cause purple orchids to decline.
 
The most frequent mistake is overwatering, which leads to root rot and yellowing leaves.
 
Another issue is placing purple orchids in direct sunlight, which burns the leaves and causes them to turn reddish or brown.
 
Using ice cubes to water purple orchids is a popular myth, but the cold can shock the roots and damage the plant.
 
Instead, always use room-temperature water when caring for purple orchids to keep the roots happy.
 
Also, avoid moving your purple orchid around too much, as they are sensitive to changes in light and temperature.
 
Finally, don’t be alarmed if older leaves on your purple orchid turn yellow and drop off—this is normal as long as new growth appears.
