The moth orchid ( Phalaenopsis spp.) has arching stems that sway softly beneath the numerous white, pink, yellow, speckled, or variegated blooms. Moth orchids are perennials that thrive in partial to full shade in USDA plant hardiness zones 10 through 12, but they can also thrive in bright, filtered light inside. While most orchids are propagated by detaching plantlets or “keikis” from the parent plant, phalaenopsis orchids can be grown from seeds using agar. Be aware that this is a lengthy process, and your young orchids may not produce flowers for another five to seven years.
Is it easy to grow orchids from seeds?
Is it possible to grow an orchid from seed? Orchids are normally grown from seed in a laboratory’s tightly regulated environment. Planting orchid seeds at home is challenging, but it is doable if you have enough time and patience. Even if you are successful in germination, it will take a month or two for the first little leaves to appear, and it could be years before you see the first bloom. It’s simple to see why orchids are so pricey.
Do orchid seeds need light to germinate?
- Remove the flasks one at a time and wrap a one-inch piece of saran wrap around the top of the lid (covering the sides of the flask to keep pathogens out) and tape shut with the label or elastic band.
*Some orchid breeders wrap the entire lid with a larger single piece of tin foil. This bothers me because it prevents light from entering from above.
After you’ve sown orchid seeds caring for flasks
I honestly didn’t believe I’d have to be concerned about this. I assumed that flasking would take up the most of my time, however as you can see, contamination began to appear in the large flasks after approximately 2-3 weeks. The little test tubes were all clear of contamination, whereas the large flasks finally became infected. Here’s what I learned after doing some research:
Temperature Changes & Flask Types Flask Contamination
I’m from Canada. In the winter, interior temperatures can range from around 25°C on hot days to 15°C (at its coldest) on cold days. The 10°C difference can cause air within the flask to expand and compress, generating air draw, which can draw in contamination. I used square flasks without threading when I first started producing orchids, and they had an EXTREMELY high rate of contamination in my conditions (literally 100 percent ). I experimented with many methods to adjust my temperatures, but the best answer for fluctuating temperatures was to utilize threaded flasks. Spice bottles, babyfood jars, and mason jars with plastic caps from Walmart have all been used. All of these alternatives have performed far better than square flasks.
Spreading: Taking PLBS from one mother flask into new mother flask
This step is only necessary if your protocorms are piled on top of one other. If you don’t do so, the seedlings beneath the top layer will eventually perish. By transferring them to a fresh mother flask, both flasks will be able to feed all of the seedlings. Because there’s always the potential of infection, you should sow fewer seeds and skip this stage if at all feasible.
Steps for Spreading Orchid Protocorm-like Bodies
Place the mother flask in the glovebox, along with a second un-sown flask containing mother media. Clean your work space as well as the outsides of both flasks. Scoop PLBs from one flask into the second with an utensil (spatula or whatever). Make every effort to avoid touching anything other than the media and PLBs. Distribute the PLBs in the old flask then spread them out in the new flask. The goal is to collect two mother flasks.
Some orchid species require darkness to germinate. Normally, this applies to terrestrial plants; however, I have had no trouble sprouting Phalaenopsis and Phragmipedium seeds by placing the flasks under lights immediately after sowing (rather than performing a “darkness treatment”).
How do you germinate orchid seeds?
Plant the seedlings 2 inches apart in the pot after washing them in lukewarm water to remove any residual agar. Place the pot in a warm, sunny location and spray the seedlings several times each day after the first week. When the orchids outgrow their original pot, transplant them to new pots.
How do you sterilize orchid seeds?
If you have little seeds, such as orchid seeds, sterilisation can be done in micro-centrifuge tubes (2mL volume) loaded with bleach solution. Mix it briefly and repeat the steps two or three times more, each time using an autoclaved yellow tip to replenish the solution. Finally, only add water a couple of times.
How do you grow Phalaenopsis orchids indoors?
Phalaenopsis orchids are among the easiest orchids to grow indoors out of all the varieties. They can produce lovely flowers that linger for several months if given the appropriate circumstances and diligent supervision.
Below are instructions for growing Phalaenopsis orchids indoors:
- Place your Phalaenopsis orchid in a window that faces east or south, or in any room in your house that gets plenty of indirect light.
- The humidity level in the room where you keep your orchid should be at least 70%. To maintain high humidity, place the pot on a tray with a layer of wet gravel. Then, to create mild air flow in the room, use a circulating fan set to the lowest setting. (Be careful not to place your orchid in the path of the airflow.)
- During the day, keep the temperature in the room between 65 and 80 degrees Fahrenheit, and at night, keep it between 60 and 70 degrees Fahrenheit.
- To pot your Phalaenopsis orchid, use pine bark mix. This potting medium can aid in the development of thick, robust, and healthy roots in the plant. Because the roots are so delicate, you must be careful not to break them when repotting.
- The majority of fertilizers are effective at promoting growth when used at modest concentrations. Once every four months, fertilize.
- Remember to inspect your orchid once a week for bugs (maybe while you’re watering it). Insecticides can be used to get rid of them if you locate any.

How many seeds are in an orchid seed pod?
Orchid seeds are tiny and have very little or no food reserves. A seed capsule can contain anything from 1,500 to 3,000,000 seeds. Immature seed can be germinated by sowing the seed in vitro (green pods). After the capsule has broken open, sterilizing the green capsule is significantly easier than sterilizing individual seeds.
Can Phalaenopsis be propagated?
A flower stem cutting cannot be used to propagate an orchid like a Phalaenopsis, as previously stated. That doesn’t rule out stem cuttings, though.
Monopodial orchid stem cuttings
Cutting the stem of a Phalaenopsis or any monopodial (single-stemmed) orchid like a Vanda can be used to propagate it. We’re not talking about a flower stalk here; we’re talking about mature orchids with so many leaves stacked on top of one another that a good-sized stem has grown.
Topping the plant is the process of cutting your orchid in half with a clean knife or shears. The bottom part of the plant, which includes roots, can be kept in its current container and will continue to develop if properly cared for.
The top section, which has no roots, can be planted in moist sphagnum moss. With any hope, it will take root and continue to grow normally.
Do Phalaenopsis orchids multiply?
You may spread the beauty and more plants to fill your house by propagating phalaenopsis orchids. The easy-to-grow moth orchid ( Phalaenopsis ) is a favorite among beginners. Planting one of the orchid’s naturally occurring offsets or plantlets, also known as keikies, that grow on nodes along its spike, or stem, is the most common way for home orchid aficionados to reproduce it. This is a division method. It’s best left to commercial growers to propagate it through seed or tissue culture, as it necessitates specialized laboratory equipment.
Can you start orchids from cuttings?
Orchid propagation from cuttings and spikes appears to be all too frequent these days. I’ve seen far too many videos and articles claiming that flower spikes and orchid stem cuttings may produce spectacular results. Some myths become real after being repeated thousands of times, such as “orchids purify the air” or “ice cubes are beneficial for orchids.” Misinformation about reproducing orchids from cuttings has resulted in some really unfortunate outcomes. Is it true that you can grow orchids from cuttings?
Cuttings of orchids can be grown, but only once a keikia new growth on the side of a Phalaenopsis flower spike or stemhas developed excellent roots and stems. Back bulb division can also be used to propagate orchids. Cutting flower spikes without a keiki and burying them in sphagnum moss for a month will not result in the establishment of new orchid plants.
