Orchids make wonderful houseplants, and a collection of orchids can provide year round blooms. The most popular and commonly sold orchids are phalaenopsis orchids, also known as moth orchids. Orchids are fairly easy to care for, and will rebloom year after year in the right conditions. Follow these orchid plant care instructions for the best results…
Growing Orchids As Houseplants
Like bromeliads, orchids are epiphytic plants. That means that in their natural habitat they don’t grow in the dirt, they grow on other plants. Don’t worry they don’t feed on other plants, they just use them as a growing support.
There are tons of different varieties of orchids, and many of them can be grown as houseplants – though some are fussier than others.
Phalaenopsis orchids are the most commonly sold variety because they aren’t that much harder to grow than your average houseplants (though they do require extra care if you want them to bloom).
Once you get the hang of caring for your orchids, and learn the tricks to get them to rebloom, they make excellent flowering houseplants.
Phalaenopsis Orchid Plant Care Instructions
The delicate flowers dangling from skinny stems is what makes orchids look so exotic… and it’s also what makes them look like they’d be really hard to grow.
But they are surprisingly easy to grow houseplants. I’ve broken down these orchid plant care instructions into small chunks to make it easier for you to digest, or simply skim through to find exactly what you’re looking for.
How Much Water Do Orchids Need?
Orchids like to be watered consistently, but don’t like soggy feet. Allow the medium to dry out slightly between waterings, but not to the point where the plant starts to shrivel.
Water thoroughly until the water comes out the bottom of the pot. Allow the water to drain fully, and never allow the pot to sit in water.
It’s especially important to use room temperature water on orchids, they are very sensitive to temperature extremes.
Humidity Requirements For Growing Orchids
Because they are a tropical indoor plant, high humidity is important for orchids. Set the plant on a pebble tray to increase humidity, or mist your plants on a regular basis.
If you mist your orchids, make sure to do it in the morning so the leaves are dry by the evening to prevent disease or fungus issues.
To increase the humidity levels for your orchid house plant, you could grow it in a sunny bathroom or near the kitchen sink, or add a humidifier in the room for your plants.
How Much Light Do Orchids Need?
The phalaenopsis orchid likes bright, indirect light. Never put your orchid house plant in full sun or it could burn the tender leaves of the plant, and the plant will suffer with too much sun.
Indirect light from a south facing window, or filtered light in an west or east facing window are the best choices.
Can Orchids Be Planted In Soil?
No. Do not use regular potting soil for orchids. Since orchids are epiphytes, they get their nutrients and moisture from the air and not the soil.
Orchids grow on the bark of trees in their natural habitat, so a potting medium made from bark (specifically made for orchids) would be the best, rather than planting orchids in soil. This is the stuff that I use… orchid potting medium.
Do Orchids Need Fertilizer?
Yes, phalaenopsis orchids will perform their best if you feed them properly. Generally speaking, it’s best to feed orchids using a weak half dose of plant fertilizer every time you water during their active growing season (May-September).
Don’t fertilize orchids during the winter, or while they are flowering. I recommend you buy a fertilizer specially made for orchids (rather than just a general houseplant fertilizer) and follow the directions on the package.
When Do Orchids Bloom?
In most cases phalaenopsis orchids are winter blooming plants, making them a popular plant sold at garden centers and big box stores around the holidays.
Phalaenopsis orchid blooms last for several months, and will usually last all the way through spring. Some types of orchids can even bloom year round!
Once they’re done blooming, the flowers will naturally drop off in the spring, which is normal.
Will My Orchid Rebloom On It’s Own?
Phalaenopsis orchids are one of the easiest orchids to get to rebloom… but they don’t usually rebloom on their own, so you’ll have to help them out a bit.
The trick to getting phalaenopsis orchids to bloom is cooler evening temperatures.
It would be best to have it at least 10F degrees cooler at night than during the day (but not below 55F) for at least a week. This is easy for those of us who live in cold climates.
When you’re anxiously waiting to see if your orchid will rebloom, it can be hard to tell if the new growth is a flower spike, or just more roots. There is a subtle difference, so look closely.
The roots have smooth and slightly pointed edges (like the ones in the photo above). Bloom spikes will have folds at the tips, and they look kinda like a tiny mitten.
If you’ve been religiously following all of these orchid plant care instructions but your orchid still won’t bloom, that’s a sign that it needs to be repotted.
Orchid Houseplant Pests
Organic neem oil is a natural insecticide that is very effective at getting rid of these nasty orchid pests. You can also use a cotton swab dipped in rubbing alcohol to kill mealybugs and houseplant scale on contact, or use an insecticidal soap.
Never use chemical pesticides on houseplant pests though because they can build up a resistance to chemicals, only making the pest problems worse.
If you’re thinking about trying your hand at growing an orchid (or maybe you got one as a gift!), then follow these simple orchid plant care instructions, and you’ll enjoy your orchid for years to come (heck, you’ll probably have a whole collection of orchids soon!).
