The orchid family includes more than 22,000 species and over 880 distinct genera. The orchid family is the largest and most diversified of all flowering plant families, and these numbers are increasing each. The majority of orchids are tropical plants that cling to trees as “air plants” or epiphytes. Some orchids grow on or amid rocks as lithophytes, or “rock plants.” Terrestrial orchids, which make up the remainder, thrive on the loamy debris of the jungle floor. It can be difficult to provide basic recommendations for orchid care with a plant family this diverse. However, there are just a few dozen commonly produced species, and even fewer are offered at a nearby nursery. Our page on orchid identification gives a brief overview of many of the common varieties. It’s likely that the plants you find at nurseries, florists, big-box hardware stores, and grocery stores are hybrids. These hybrids were developed by mating various species, and occasionally genera, in order to breed out many of the difficult care requirements of pure orchid species while introducing desired traits including color, aroma, blossom size, and ease of care. If you spend a little time learning about their fundamental requirements, today’s hybrid orchids make for very rewarding indoor plants.
Are orchids able to live in the air?
We rejoice in the warmth and rebirth of the season as spring progresses and summer draws near. If you own an orchid, though, you should be mindful that warmer air may bring unseen dangers to your prized plant.
Here, we go through four potential hazards to springtime orchids and how to safeguard your plant.
Windows: Silent, but Deadly
On the first warm spring day, what is one of the first things you do? Unlock a window! It feels good to throw open a few windows and let some fresh air in after a long, chilly winter spent indoors. Air might be beneficial for your orchid as long as it isn’t too dry. Your plant won’t thrive if the air is too hot, too dry, or both; orchids need moisture and humidity to survive.
Don’t place your orchid close to an open window if you live in a desert or a region with dry heat.
Use Caution with Cool Breezes
The ideal daytime temperature for orchid health is between 65 and 80 degrees Fahrenheit; nevertheless, temperatures that exceed 80 degrees are sometimes experienced early in the season. And when they do, you turn on the air conditioner, just like many other people. Although this is excellent for keeping you and your family cool, it may be harmful to your orchid. Air that is too cold will shock your plant, which could lead to “bud blast,” or early bud fall.
Keep your orchid well away from air conditioner vents and direct air flow. Your flower should be placed in a space that is regularly between 65 and 80 degrees Fahrenheit during the day and 55 to 65 degrees Fahrenheit at night.
A Fan is Not an Orchid’s Friend
Quick and easy cooling down is possible with a fan. This is why, especially at night, people frequently run their ceiling fans at a high setting or position fans in their windows. Orchids thrive in temperatures between 55 and 65 degrees Fahrenheit at night, but under a fan’s direct line of sight, the temperature may fall significantly lower.
Tip: Keep your orchid away from the direct path of air if you use a fan to cool down your home.
Too Much Humidity can Harm
Although orchids enjoy dampness, too much of it can be harmful. You must keep an eye on the humidity levels in your orchid if you reside in a region with high humidity. When humidity levels are between 55 and 75 percent, phalaenopsis orchids flourish; however, excessive moisture promotes bacterial and fungal growth, which can result in orchid illnesses. A bad smell emanating from your plant is a sure sign that there is too much moisture present.
Advice: Dry out your plant at night by putting it in a low moisture region of your home if you expose it to a lot of humidity during the day. Apply a natural fungicide to your plant if it has a bacterial infection.
Enjoy the warm weather in spring and summer, but keep in mind these safety measures to help protect your plant.

An air plant is what kind of a plant?
Tillandsias, a member of the Bromeliaceae or Bromeliad species, is the true name for air plants. They are also known as epiphytes since they can grow without soil. In Central and South America, Mexico, and the southern United States in North America, the air plant is frequently found in the jungles, on mountain tops, and in deserts.
Because they are an epiphyte species, air plants may grow without soil. They do in fact need a platform to start growing. These plants rely on their host for support and are not parasitic. The moisture and dust fibers that are drifting through the air provide the plant with its sustenance. The basic purpose of the roots is to affix itself to the supporting subject.
These sorts of plants require little maintenance. For their wellbeing, regular watering, healthy air circulation, and dazzling filtered light are crucial. You can spritz your plants entirely 2-3 times each week or immerse them in water for about 20 minutes once a week. Allow them if they reside in a container or plate. Prior to moving them back with their storage containers, allow them to dry for three to four hours. Instead of doing so during the day, air plants absorb carbon monoxide at night. The plant can’t breathe properly if it is moist. This information indicates that morning watering is always preferred. Make sure there is enough airflow in every container used. Your plants will prefer filtered or indirect light; never leave them in full sunshine for long periods of time.
Only once during their lifetimes do air plants flower, yet during this time they will produce pups or progeny. After the pup is one-third to one-half the length of the parent, it normally stays connected to the parent or can be separated with a delicate twisting/pulling motion at the base of the plant. Simply remove the parent leaves when they wither and die if the pups remain linked. As a result, the space will quickly fill with pups.
Almost anywhere can be used to grow air plants. Driftwood, old picture frames, seashells, and pottery can all have them added to them. To attach those to pressure-treated wood, copper objects, or copper cable is strictly forbidden and will result in the destruction of your plant. In general, if you decide to attach them all, you can use reasonably priced specialty glues.
Can you keep orchids inside?
When I was twelve years old and living in the Ukraine, I acquired my first orchid plant. I was captivated by an orchid’s capacity to root and grow totally above the ground. My passion in growing orchids inside quickly led to the acquisition of a collection, and finally my hobby became my business. For thousands of years, people have been fascinated with orchids because of their peculiar growth patterns and mysterious blossoms. However, the majority of what we currently understand about orchid culture was only amassed in the previous 200 years or so.
Early in the 18th century, plant hunters imported several epiphytic orchids to Europe. Epiphytes, also referred to as air plants, are plants that grow on other plants without attaching to the soil or causing harm to their hosts. However, European producers kept the orchids in warm, stuffy, poorly ventilated buildings, which was disastrous for the plants. It was around this time that the myth that orchids were challenging to nurture first appeared. It took nearly a century for growers to discover effective orchid care techniques.
Many orchids are as simple to grow as African violets, as we now know. Epiphytic orchids, which early British orchid gardeners regarded as so obstinate and troublesome, are the easiest to grow inside.
Here, I’ll concentrate on growing orchids inside, especially those that do best in a home atmosphere with typical environmental conditions. Knowing an orchid’s requirements, picking an orchid based on the conditions you can supply, and providing it with the appropriate care are the keys to success.
Orchids vary in their temperature preferences
An orchid’s general growth and, in particular, its blooming tendencies, are influenced by temperature. Winter, when many orchids are getting ready to bloom, is the most crucial season for them. According to the types of temperatures they require in the winter, orchids can grow in three different ways: cool, intermediate, and warm.
In the winter, cool-growing orchids prefer nighttime lows of 50°F and daytime highs of no more than 70°F. Orchids with intermediate growth rates prefer daytime temperatures of 70 to 85 and a minimum winter nighttime temperature of around 60. Most orchids in the intermediate group are those that fare well indoors (see sidebar). Winter daytime temperatures can vary from 75 to 85 degrees, but nighttime temperatures for warm-growing orchids shouldn’t drop below 65. As long as they have excellent air circulation, intermediate- and warm-growing orchids may withstand summertime temperatures of up to 85 or 90 degrees. Orchids that develop slowly prefer it to be chilly during the summer.
All orchids require a temperature difference of 10 to 20 degrees between the day and the night in order to flower. Because of the conditions that cool- and intermediate-growing orchids are accustomed to in the wild, this distinction is most significant for them. You can achieve this fluctuation in the winter by turning down the thermostat in your house or by shifting an orchid to a cooler location at night, such as a porch or a garage.
Most orchids thrive in direct, bright light. Usually, adequate light is provided by full eastern or western exposure or indirect southern exposure. But like with temperature, some orchids might need a particular level of light. When purchasing an orchid, read the label to determine how much light it prefers, then pay attention to how much light your orchid actually gets.
Sunburn, yellowing foliage, and a plant that seems weak and dehydrated are all signs of too much light. On the other hand, even though the foliage appears to be full and green, if you purchased an orchid in bloom and it did not bloom the following year, you might want to give it extra light. Make sure the temperature range is accurate, as well.
Too much water can be as deadly as too little
The most challenging part of raising orchids is watering. The majority of epiphytic orchids need a loose potting mixture to grow. Drench the mixture until water runs out the bottom to ensure that the orchid receives enough water. Before you water the orchid again, let the potting mix dry up. Don’t be misled into thinking that the orchid requires more water because the top layer will dry out more quickly than the bottom layer of soil.
Comparing an orchid’s weight before and after watering is a quick and easy approach to determine when it needs water. Before testing, make sure the plant is totally dry, then pay attention to how it feels when you raise it. Knowing the difference will allow you to calculate how much moisture is still there in the container. If you are unsure whether to water your orchid or not, wait a day, say seasoned orchid growers.
Also bear in mind that during their resting phase, when they are not blooming or developing new growth, orchids require less water. An orchid can receive additional water when new roots and shoots start to emerge.
Orchids that are dormant often require watering once each week. I water them twice a week or more while they are actively growing. However, you should not strictly abide by this rule; instead, use your best judgment. The temperature, the size of the container, and the potting mix will all affect how much water is required. The fresh stems and leaves of an orchid that has been dry for too long will have shrunk and become wilted. A plant that receives too much water can eventually develop root rot and become dehydrated.
Most orchids also benefit from moderate humidity (50 percent or higher). You can accomplish this by frequently misting them with water or by using a humidifier in your house. Fertilizing orchids with a reduced-strength fertilizer once or twice a month during the growing season can encourage healthy growth and robust flowers. A 20-20-20 solution is my go-to equation.
Many orchid growers I’ve met have a certain soil mixture they can’t live without. In my experience, while potting up an orchid, it doesn’t matter what kind of components and how much of them you use. The mixture merely has to be airy, drain well, and degrade gradually. If those conditions are met, it doesn’t matter if you make your own or buy a readymade mix; it will still function. There are several alternatives, including bark, peat moss, sphagnum moss, and tree fern fiber.
However, given that orchids enjoy being root-bound, container size is a crucial consideration. Their roots frequently extend directly into the air outside the container. The plant may not necessarily require a larger pot as a result. To select when to repot, see to the sidebar above. The new container ought to be just big enough to hold the root system and allow for growth over the course of the following year or two. You are free to choose a clay or plastic pot.
It’s not required to divide every time you repot. I prefer to allow an orchid to develop into a larger specimen that has numerous flowers. One justification for dividing a plant is a lack of growing space, together with the desire to have more than one plant or to exchange with friends. Each division, also known as a pseudobulb, needs at least three established stems to develop swiftly into a healthy blooming plant. There are a lot of old, bloomed-out pseudobulbs in orchids. If these are still green, leave them alone; if they are dry and yellow, clip them off.
Keep an eye out for pests and disease
Orchids are typically trouble-free with proper maintenance, which includes sufficient air circulation. The discovery of an orchid suffering from disease or being tormented by pests, however, can be sad. A key to maintaining the health of orchids is early detection. It will be simpler to repair a problem the earlier you identify it.
I separate a problematic plant from its neighbors first. I personally exterminate pests like scale, aphids, or mealy bugs using a gentle brush if they are visible. I might use a pesticide if a pest does get out of control. After the therapy, I keep the plant in isolation for another two to four weeks while periodically checking on it.
The appearance of bacterial or fungal illnesses on orchids may be a sign of cultural issues. Finding the disease is the first step. The following phase is to assess growing methods and make any necessary adjustments. For instance, insufficient air circulation may contribute to fungal illness. Reducing watering is important for some bacterial illnesses. Sometimes a shift in culture will be sufficient to solve the issue. If not, try a more forceful course of action. For assistance in selecting a suitable fungicide or bactericide, speak with your neighborhood extension agent or garden center.
Orchids love the summertime air since it’s so refreshing. Of course, the outdoor environment should mirror the indoor environment you have created for your plants. When the season for flowering arrives, it is acceptable to put your treasure on display outside of the growing area in a place of honor. The plant won’t suffer if it receives less light for a few weeks; in fact, it will be pleased of you for your accomplishment.
Start with these easy orchids
The orchid species listed below are some of the simplest to grow indoors. When it comes to temperature requirements, the majority of the orchids in these categories are categorized as intermediate-growing orchids. In other words, they enjoy daytime temperatures of 70 to 85 F and minimum winter nighttime temperatures of around 60 F.
The small to medium-sized tropical lady’s slippers (Paphiopedilum spp. and cvs.) have gorgeous, waxy flowers that persist a long time and leaves that are frequently mottled. They thrive indoors because they can handle reduced light levels. More than a day or two of dryness bothers them, especially when they are developing or blooming. Winter and spring is the blooming season.
This category covers Cattleya, Laelia, Rhyncholaelia, Sophronitis species and cultivars, as well as their hybrids. Small to medium-sized plants produce medium-sized to huge, vividly colored blooms. They require filtered bright light for blooming. Before watering the plant, the potting mixture should be extremely dry. Winter through late spring is the bloom season.
Some of the simplest to grow orchids are included in this group, including Doritis and Phalaenopsis species and cultivars. These medium-sized plants produce long-lasting sprays of small, medium, or big blooms. They favor filtered light, consistent watering, and brief dry intervals. Winter blooming lasts through late spring.
