The term “moth orchid” refers to the flower’s likeness to a flying moth. One of more than 25,000 species of orchids, the moth orchid (Phalaenopsis spp.) is indigenous to Asia. This plant is an epiphyte since it grows on tree branches high in the forest canopy. Moth orchids have 2 to 3 foot tall stems with thick olive leaves and flowers that bloom in shades of white and pink. A moth orchid’s blooms can endure up to 120 days. Moth orchids can bloom again on a spike around three months after the flowers start to fade. With the right care and the right growing conditions, a healthy specimen produces blossoms for approximately half a year.
Use sterile pruning shears to trim the stem below the wasted flower clusters. Leave two nodes, or the brown lines, at the very least, on the spike. One of the remaining nodes produces new flowers.
Place the orchid in a space that maintains a temperature of at least 60 F during the night and between 65 and 75 F during the day. The plant blooms again when nighttime temperatures hover around 55 degrees Fahrenheit for several weeks.
When the soil seems mostly dry, water the moth orchid. Use water that is room temperature and let the pot’s extra water drain completely. To avoid decay, water the crown in the morning and pat it dry at the base with a towel.
Use a 10-30-20 fertilizer on the orchid twice a month, following the dose instructions on the package. The increased phosphorus levels promote reblooming. During humid, warm weather, you can choose to use the same fertilizer at a quarter dose with each watering.
Put the pot in an area with strong indirect light, like an east-facing window. A lot of light is required for the moth orchid to blossom again. When the plant receives too much light, the leaves take on a reddish hue; when it receives too little light, they become a darker green.
Give a relative humidity range of 50% to 80%. The humidity is lower in many residences. Put the moth orchid in a humidifier or on a tray of rocks with water filled to just below the tops of the pebbles.
How can an orchid be made to bloom?
Moth orchids are a favorite among gardeners because of their soft, smooth petals, elegant stems, and vibrant colors. Even if you don’t have a green thumb, they are simple to grow and have long-lasting blooms. But after going into dormancy, how can you get your orchid to bloom again?
How to Make Orchids Rebloom
If you enjoy orchids, you undoubtedly already know how crucial dormancy is to them. It provides the plants with a period of rest so they can replenish the nutrients used to develop those beautiful, eye-catching blossoms. However, there are a few techniques for reviving orchid blooms.
- Feed them. Use an orchid-specific fertilizer on a regular basis once your orchid has finished blooming.
- Irrigate them. If the roots of your orchid become dry in between waterings, you are not providing it with adequate moisture. Make sure there is enough drainage in your pot. You can place the pot on a tray of pebbles to keep the roots extra wet; just make sure it’s not sitting in standing water but rather on top of it.
- Fire them up. For orchids to bloom to their greatest capacity, strong light is necessary. One frequent cause of orchids not blooming is a poor light source. However, they shouldn’t be exposed to direct sunlight either. Make sure your orchids get enough light access without placing them in the sun.
- Temp them. Moth orchids produce flowers from winter through spring. When there is a 10 to 15 degree difference in temperature between day and night, they blossom in response to the sharp change in temperature. By shifting the pot to a cooler place at night, you can trick your orchid into flowering again.

How long does a moth orchid require to bloom?
A phalaenopsis orchid’s life cycle is comparable to that of a common flower. It has six stages: seed germination, seed development, seed maturation, blooming, and reproduction. A phalaenopsis orchid can live for many years or even decades if it is properly cared for.
From Pollination to Blooming
Pollination is the first phase of the life cycle of an orchid. The orchid produces seed pods as a result of this activity, which starts a chemical reaction that begins the reproduction cycle. It will take 6 to 8 months for the seed pods to mature. The plant will draw energy from its leaves to produce blossoms, which could result in some leaves turning yellow and dropping off. The average time it takes a phalaenopsis orchid to flower is three months.
The orchid will develop many roots after it has completed flowering so that it can obtain the nutrients required to begin flowering once more. A phalaenopsis orchid’s flowers often bloom for several months, and throughout this time, the plant can be pollinated once more. An orchid’s life cycle can be finished in anywhere between 9 and 14 months. It normally blooms once every 8 to 12 months if it does not pass away.
Varying Factors
The lifetime, length of flowering, and frequency of reblooming of phalaenopsis orchids differ from flower to flower. You must give your orchid the proper lighting and humidity levels, as well as weekly watering, if you want it to be healthy and long-lasting.
How frequently do moth orchids flower?
One of the longest blooming orchid genera is Phalaenopsis, which produces flowers that last between two and six months before falling off. Once plants reach a mature size, phalaenopsis have also been observed to bloom two to three times annually. Cut the stem immediately above the node where the first blossom opened after it has flowered once. Within two months, a new blossom stem from the top node should appear. Cut off the flower spike close to where it came from the plant if there is no reaction or if it turns brown.
Will the moth orchid ever rebloom?
In the 1990s, when I started working at Gardener’s Supply, my Vermont backyard was lush with grass. Only a very little portion of the original lawn is visible now. The majority of the available space has been taken over by masonry, trees, bushes, perennials, and annuals.
I also worked at Church Hill Landscapes’ gardening division while I was employed at Gardener’s Supply. In that capacity, I oversaw the upkeep of numerous gardens and the planting of countless perennials, shrubs, and trees.
In order to pursue a master’s degree in ecological landscape design at the Conway School, I left Gardener’s Supply in 2017. Discover my training portfolio by clicking here. You may connect with me on LinkedIn.
Your phalaenopsis will blossom again if you pay attention to light, water, and fertilizer.
Phalaenopsis (moth orchids) are among the most straightforward orchid species to grow. The blooms endure for several months, and you may easily get them to rebloom. Well, a few people can. I have a shelf full of non-blooming phalaenopsis to show that I haven’t had much success in getting another bloom. I have to admit, I feel a little embarrassed. How can I make my orchids blossom once more?
I spoke with Anita Nadeau, our orchid specialist at Gardener’s Supply, in an effort to increase my success. She assists customers in the conservatory at our garden center in Williston, Vermont. She offers the following advice for reblooming phalaenopsis:
Pay care to the humidity and watering. Your phalaenopsis won’t blossom if you don’t take care of it. You must water frequently because the plants are presumably growing in a free-draining mixture of fir bark. Between waterings, keep the roots from drying out completely. Wintertime humidity levels in most homes are rather low, but you can raise them by placing the orchid pots on a tray of stones or a specific humidity grid placed within a waterproof tray. Check to make sure the pots are just above the water, not in it.
Regularly fertilize. The importance of a regimen for fertilizing and watering is equal. Anita advises feeding orchids water-soluble fertilizer that has been specially developed for them. Mix according to the directions on the package.
Ensure sufficient lighting for plants?
but not excessively. According to Anita, when a healthy orchid doesn’t bloom, it’s typically because there isn’t enough light. Bright light is ideal for phalaenopsis, but not direct sunlight. The best windows are those that face east or west. Orchids can also grow in full-spectrum lighting if you are unable to give sufficient natural light.
With a grow light like this Medium Bamboo LED Grow Light, you can ensure optimum illumination even if you don’t have a window that gets plenty of sunlight.
Make the nights cool. The majority of orchids do best when the temperature drops significantly at night, typically by 10 to 15 degrees F. Phalaenopsis are more tolerant in this regard, although a plant that is reluctant to bloom can typically be encouraged to do so more easily if it is grown in an area with cool nights.
Why is my orchid not blooming?
- Lack of light, nights that are too warm to encourage flowering, or orchids that are too stressed from low humidity to create flowers are the usual causes of orchids not blooming. High humidity, intense indirect light, and chilly nighttime temperatures are all necessary for orchids to flower.
- The orchid is stimulated to generate new flower spikes and exhibit flowers by the variation in temperature between day and night.
- Once plants have flowered, moth orchids do not produce further flowers at the same nodes on a flower spike. If the orchid’s flower spike is going yellow or brown, trim it back to half an inch above a sprouting new growth or to the base of the orchid.
- Without routine fertilization, orchids do not flower as effectively because the roots can deplete the nutrients in the potting material. To ensure the orchid has the nutrients available for flowering, use a specific orchid fertilizer in the spring and summer.
- Tropical plants like orchids prefer a humidity level of about 50%. The orchid is frequently too stressed to produce any blossoms if the humidity level surrounding the roots, stem, and flowers is too low.
- An aerated potting medium, like pine bark, that allows water to drain well is necessary for orchids. The orchid’s roots will rot if the soil or potting material is too wet, which will stress the plant and prevent it from blooming.
- Reduce the nighttime temperature by 10F for 2-4 weeks to encourage orchid blooming. This encourages the growth of new flower spikes. In order to give your orchid the nutrients it needs to start blossoming so that it can bloom once more, use a specific orchid fertilizer in the spring.
Why don’t my orchid’s blooms bloom, only their leaves?
Overall, inadequate light is the most frequent cause of orchid bloom failure. The filtered light from a windowsill is usually enough light for Phalaenopsis and Paphiopedilum orchids, but many other types require more. For the kind of light levels they need to bloom, medium- to high-light orchids like Dendrobium, Cattleya, Oncidium, and others may need additional grow lights or time spent outside in the summer. Unlike tomato plants, orchids cannot generally tolerate full sun. The best type of shade is dappled, and despite the appearance, a brilliant window does not provide more light than natural shadow.
An orchid’s leaves lighten in color as it receives more light. Very dark forest green leaves can suggest too little light, but very light yellow-green leaves typically indicate too much light. In conclusion, if an indoor windowsill-grown Dendrobium, Cattleya, Oncidium, Cymbidium, Vanda, Brassia, or other high-light orchid hasn’t blossomed in a year or two, it probably isn’t getting enough light.
One method is to place orchids that need a lot of light in a vanda basket that’s suspended from a tree branch. High light orchids can have a vigorous growth season when there is increased humidity along with enough watering. With this kind of care, Dendrobiums have been known to blossom again even after spending a long time dormant on a windowsill. More light was essential for the bloom to appear.
Which fertilizer promotes orchid blooming the best?
Feeding orchids frequently is necessary. Growers advise applying a fertilizer that is “balanced” and has all “essential trace elements,” such as 20-20-20. Whatever fertilizer mix you decide to use, it need to have little to no urea in it.
What are moth orchids fed?
Yates Specialty Potting Mix for Orchids should fill half the pot. Fill the pot with the remaining orchid mix after adding the plant. Add a little water. During the times of flowering and leaf growth, feed your orchids with Yates Thrive Orchid Liquid Plant Food every two to four weeks.
Do orchids benefit from used coffee grounds?
Your difficult-to-grow orchids will require appropriate feeding in order to thrive. When the leaves and roots of an orchid are actively growing, relatively little fertilizer is needed.
The American Orchid Society advises giving your plants a 20-20-20 fertilizer with little to no urea on a regular basis.
Another suggestion is to fertilize with water-soluble fertilizer at a quarter strength each time you water your plant. This means to mix it with water and use only a fourth of the amount recommended on the label. Weekly application of this mixture is recommended for orchids because it’s preferable to underfertilize than overfertilize.
Prior to fertilization, make sure the potting mix is slightly damp because completely dry potting mixes might burn the roots.
Coffee grounds make a great fertilizer, especially for African violets and orchids.
I’ll discuss how much light you should and shouldn’t expose the orchids you’re caring for on the show tomorrow.
What time of year do orchids bloom?
Orchids grown as potted plants have varied blooming seasons, depending on their species. There are certain varieties of orchids that bloom in the winter, summer, or fall, but March is often when they reach their peak blooming period.
How much time does an orchid need to flower?
After that, one of the lower nodes will start to grow, and in eight to twelve weeks, blossoms will appear. Cut the stem completely off and let the plant fall dormant if the bloom cycle doesn’t begin in two months or if the stem starts to turn yellow.
